The Gemini PDA, it's as close to a Psion as you'll get (and it's real)

Before the iPhone or even Blackberry, there was a PDA made by a company called Psion, well several, eventually culminating in the Series 5. It was a clamshell design with a keyboard on one side and the monochrome screen on the other. It could run applications and it did basic things like had a calendar, calculator and word processor, all driven by a toolbar running along the bottom of the screen. It also had a 'view' screen to see what was happening throughout your life (well days/weeks anyway).

Unfortunately Psion is no more, however a company called Planet Computers is trying to change that and though the actual Psion can't be resurrected, the Gemini is born. The company was set-up by Dr Janko Mrsic-Flogel who used to resell Psion hardware and develop software and has developed a lot of mobile cloud solutions under another company (Private Planet Ltd).

The Gemini looks and feels like a Psion 5

The PDA on the left is an actual working Psion 5 and the PDA on the right the Gemini - they do look remarkably similar. It's worth noting that the Gemini is also running a view screen that emulates the Psion calendar view, giving access to what's coming up in an easy to read manner.

The next picture shows another comparison, but with a lot of test keyboards too.

The various keyboards are for testing different membrane thicknesses and how 'clicky' the keys are. The current thinking is a softer keyboard which will probably appeal more to modern computer users who are used to the light touch, while programmers would probably prefer the keyboard with a deeper travel and more 'Cherry mechanical' keyboard feel (the programmers will probably lose out). But either way, it's perfect possible to touch type on either one.

Underneath the keyboard sits a big battery (removable Li-Ion 4220mAh) giving 12 hours talk-time and a full 2 weeks in standby.

The screen is a 5.99 inch FHD (18:9) with a resolution of 2160x1080 at 403 ppi and full colour. It looks very good. The Gemini doesn't come lightly spec'ed either with: -

• CPU - Mediatek MT6797X Helio X27 with 10 cores (2 x Cortex A72 @ 2.6GHz, 4 x Cortex A53 @ 2.0GHz, 4 x Cortex A53 @ 1.6GHz
• GPU - Quad core Mali T880 MP4 @ 875MHz
• RAM - 4GB
• ROM - 64GB
• Sound - Stereo speakers (either side of display)
• Microphone - integrated behind display and external 3.5mm jack
• Bluetooth - v4.0
• GPS - GPS and AGPS
• USB - 2 USB C ports (OTG support)
• Camera - front facing 5MP
• Sensors - accelerometer, gyroscope, compass, magneto-sensor, light sensor
• SD Card slot - takes at least 128GB, may take 256GB

The Gemini comes in 2 versions, WiFi only and WiFi with 4G. The specs for the 4G model are: -

• WiFi - 802.11a/b/g/n/ac
• GSM - 850/900/1800/1900 Mhz
• CDMA - 850/1900 Mhz BC0 BC1+ EVDO
• WCDMA - 900/2100 Mhz
• LTE - 1/2/3/4/5/7/12/17/20/41 and VoLTE

The 4G models has SIM slot (under the top lid) and both have an external camera module space (for a later rear 5MP camera module). There are also 5 fully programmable RGB LEDs on the lid, which can be programmed for fun, but also to light up to indicate, say, who's calling. When the phone rings, it can be operated without ever opening the case.

The Gemini's default operating system is Android (currently 7.1) and it will run many standard Android apps, but in order to make it more Psion like, there's a toolbar at the bottom of the screen that can launch specified apps (as well as using various Psion like key combinations).

There's a dedicated voice assist button giving access to Google's voice system.

A quirk is the Gemini can also dual-boot and the second partition holds Linux (currently Debian, but Planet will open source at least enough of the Linux side so other variants can be installed). Linux can also be run as a VM under Android (yes it does work).

All Planet apps can be run locally (with no need for access into the cloud), or they can link into the Private Planet cloud service (or Google's).

There will be a range of peripherals, but on launch there's a USB-C to HDMI adapter and a USB-C hub with 3 USB-A sockets, Ethernet port (and maybe others). There's also a USB-C mains charger and a nice leather pouch.

Using the HDMI adapter, an external HD display is easily driven running video/etc.

The Gemini is currently selling 'in-demand ' on Indiegogo (the original target was for $200,000 and it's now at over $800,000).

The WiFi only version sells for $299 and the WiFi + 4G is $399 (prices are likely to go up by $200 after the campaign).

The Gemini is a very nice unit and completely usable as a mobile phone, but with a full features of a PDA with a touch-typable keyboard so allowing productivity apps and leisure apps like video to run, even at the same time and it will fit into a jacket pocket.

It's a badge of honour, that changes face

Another day, another Crowdfunded project, this time it's a Bluetooth connected connected badge (or Pin as those over the pond like to call them).

Pins Collective are the people behind the badge (which is round) is about 2 inches across and the colour display has a resolution of 300 x 300 pixels. Information is sent to the badge using an iOS of Android app (using BLE i.e. Bluetooth version 4+ so it's needs to be a reasonably recent phone). The battery lasts around 6-72h depending on what the badge has to do (animation, backlight, etc).

Currently the app is pretty basic (in iOS) allowing selection of an image and sending it to the badge (and of course pairing the badge in the first place).

The badge will display GIFs (including animated GIFs, so you can get some spiffy moving images). The app will I,port and convert various image file formats to the correct version for the badge. Images bigger than 300x300 will be cropped.

Wearing pictures of your colleagues can be quite annoying to them.

Currently they're available to pre-order through Indiegogo at $69.

Alivecor Kardia

Alivecor make products that read your EKG. The Kardia Band was previously reviewed and although convenient as it's always on your wrist (it's an Apple Watch add-on) it's extremely susceptible to movement, external interference and lots of other constraints so it's not always easy to get an accurate reading. It also takes a while to process the result as a lot of noise has to be filtered out.

The Kardia Mobile is much easier to use. It's a unit with two electrode pads on it (underneath there's a battery compartment which holds a CR2016 coin cell) which should give about 12 months of use.

Download the free iOS or Android Kardia app and then set-up an account. Then take a reading and the app will search for the Kardia Mobile device and pair with it (it uses Bluetooth 4 so a recent'ish iOS or Android phone must be used with a recent OS).

The app will wait a while, while you put your first and second fingers from both hands on either pad, then relax and the app will record your EKG. It needs to read about 30 seconds to get a sensible heart rate reading.

After the reading is saved it will tell you if there are any abnormalities or anything. As the pads are large and the signal is being received from across the body, the results are much cleaner and less susceptible to interference (compared to the Watch version).

The EKG Characteristics are single lead ECG, 10 mV peak-to-peak input dynamic range, 30 second to 5 minute recording duration, 300 samples per second sampling rate at 16 bit resolution.

There are extra features such as unlimited storage and history, summary reports for your doctor, blood pressure monitoring and tracking weight and medication (though the last two need manual intervention) that are available through the premium service which is available as an in-app purchase.

There's also a phone attachment strip that allows the Kardia Mobile to be carried with the phone (glues on to the phone).

The Kardia Mobile costs £99 direct from Alivecor.

Xiaomi Huami AMAZFIT A1603 Smartband

Xiaomi make lots of stuff, but they also work with partners and specifically Huami who make wearables (under the AMAZFIT brand). In the US it's known as the Amazfit ARC.

Though the functionality is almost identical to the Xiaomi Band 2, it looks much nicer and the silicon strap has a 'hatch' effect on it which is very comfortable to wear. The actual unit is permanently attached to the strap and has a soft 'brushed' metal feel. Underneath there's an optical heart rate sensor and charging pins and the top is a UV coated scratch resistant OLED display.

Like most trackers it measures steps but also sleep (you obviously have to wear it at night), distance and active calories. The battery life is VERY good (Huami claim 20 days). It can also display notifications from your phone (currently iOS and Android are supported).

As a bonus it's also water proof and can be used when swimming, though it doesn't track swimming.

There's a USB charging cable that is magnetically polarised so it 'snaps' on to the charging pins on the bottom of the unit, this also stops you getting it the wrong way around.

There is an Amazfit app available and through it's pretty basic, it does support all the devices features and notifications, alarms etc can be set through it. However, it the ARC also works with the Xiaomi Mi Fit app, which has a lot more features and links with Apple Health and Android Fit on the relevant platforms. The Mi Fit app also seems to have a few more advanced features like being able to track heart rate when sleeping which give more accurate results (though reduces battery life).

It's definitely a cut above the Mi Band2 in terms of looks and comfort and on a par with traditional fitness trackers from established US companies, though at a very competitive price. However, the apps of more expensive western vendors are generally quite a bit better with more functionality.

The list price is $99 from the US Amazfit site, but various Asian sites have it available for around £30 including shipping.

Kardia Band - an ECG monitor for your Apple Watch

The Kardia Band is made by AliveCor and is a watch strap for the Apple Watch (it comes in both 38 and 42mm versions). It replaces the standard Apple Watch strap and there's a big chunk of metal in the bottom strap.

To record your ECG place your thumb on the metal blob and your fore-finger onto the other side of your wrist. Run the Kardio app, sit back and RELAX. It's VERY sensitive to any kind of movement. After 30 seconds it will beep and then press save and it will try and filter out your ECG. If you move or there's lots of electric interference it's unlikely you'll get a good reading. Assuming you're not moving around much and the software processes the data, you'll then get a normal (or not) reading and you can scroll through the waveform, like it's been printed on paper and you move along along it.

AliveCor also make a Bluetooth version where you place your fingers on which is actually considerably cheaper and I'd guess gives better readings, but then you have to remember to take it with you or buy their special iPhone cases which wil hold the device.

The Kardia band does work and it's not reported any abnormal heart readings, which is probably a good thing. It's nice that you can take a reading whenever you like (as long as your wearing your Apple Watch), but it's very sensitive to environmental conditions.

The Kardia Band costs £199 in the UK directly from the AliveCor site (it's not available in the US as it's not FDA approved). The watch strap and metal insert have been improved since earliy version when the metal bit tended to fall out.

The Kardia Mobile Bluetooth sensor is available for £99 from AliveCor and is also available in the US.

Hologram - a developer friendly international SIM

Hologram is a US company that offers both a hardware cellular device called a Dash, back-end cloud services and international SIMs that can be used globally.

The Dash is programmable through the Arduino IDE (and is supported out the box in recent versions) and the Dash firmware directly supports Holograms cloud services.

The cloud services know about Dash devices and then various routes can be set, which allow things to be sent to the Dash or from the Dash to another service (like IFTTT, Slack, etc).

The SIM is a standard 2G/3G SIM that can be fitted in a Dash and then be used on any supported mobile network. There are various pricing models with paid plans starting at $0.40 per month with data costing $0.60 / MB (billed by KB) in a pay-as-you-go service or pre-pay: -

>

Data	Zone 1	Zone 2
500KB	$0.59	------
1MB	$0.99	$1.29
2MB	$1.49	$1.99
3MB	$1.49	$2.99
5MB	$2.99	$3.99
10MB	$3.99	$6.99
20MB	$5.99	$12.99
30MB	$6.99	$16.99
50MB	$7.99	$28.99
100MB	$14.99	$47.99
125MB	$18.99	$59.99
250MB	$32.99	------
500MB	$55.99	------

There are also US only plans: -

$8.00	250MB
$12.00	500MB
$20.00	1GB
$36.00	2GB
$70.00	5GB

SMS	Zone 1	Zone 2
INBOUND (to device)	FREE	FREE
OUTBOUND (from device)	$0.19 / Message	$0.30 / Message

Zone 1 is EU, US etc and Zone 2 Canada, bits of Africa/South America and other odd countries.

Hologram have just announced a Developer plan (1 SIM ONLY), which gives 1MB per month absolutely free (and then $0.60 per MB billed by KB) and they'll even ship it for free using code "DEVPLANBLASTOFF" (no quotes).

That's pretty useful so testing the service is easy, without spending a lot of data charges.

The Dash has some pretty nice features too, such as being able to sent program and even firmware updates OTA (though that's going to quickly eat data, especially for firmware updates).

Google Glass Zombie Edition

Google launched its "augmented reality" device (Google Glass Explorer Edition) in 2013 to much fanfare, though the hype soon overtook the realities of the product. Though never aimed at consumers (it cost around £1,000), the media, and to some degree Google, positioned it as that. Then came the crash and people wearing Glass were known as "glassholes".

Google Glass Explored Edition was just that, a platform that "explorers" i.e. developers, could start experimenting with augmented apps. Though the device did have a camera and wearers could take snaps of things they saw and camera info could be used by apps, Glass is really more of a Head's Up Display (HUD).

In 2015 Google stopped production of the Explorer Edition, but quietly in the background apps were developed and Glass found a market in the industrial, scientific and medical (ISM) arenas. Think surgery and having access to patient data or access to information about the operation, or in industry working on some device and instant access to pertinent information maybe an instruction or service manual. The list goes on and in these areas, lightweight HUD technology is a big winner.

Now it's 2017 and Google have announced Google Glass Enterprise Edition. This will be sold by resellers and positioned squarely for the ISM markets and launch partners were in those very fields. It's definitely NOT a consumer device. Google were right all along and there's a good chance they sell lots of units in those specialist areas.

The other contender is Microsoft Hololens, again people are writing it off as an expensive tech gadget, but Hololens is to Microsoft and Glass is to Google.

So long Arquiva, hello WND

SIGFOX, the low power wide area network system have dumped Arqiva and now selected WND (who have successfully deployed SIGFOX networks in Brazil, Mexico, Columbia and Argentina). WND have already installed 50 base-station since they launched in March 2017 which covers 34% of the UK's population and have committed to 95% by 2019.

SIGFOX is a narrow band system using the license exempt 868MHz band in the UK (and EU in general), it's low power and long range so is designed for deployments that can be powered off batteries or power scavenging techniques and then left alone to monitor whatever they're designed to monitor.

SIGFOX supports 140 uplink messages per day (12 bytes in size, bit packed format determined by the user) and 4 downlink messages per day (8 bytes bit packed format). Uplink is from the remote site to the SIGFOX network and downlink is from the central service, though SIGFOX to the remote service.

There are other competing technologies such as LoRaWAN and specifically The Things Network, but their service sits on top of existing ISP connections, so there may be regulatory and other issues as well as a lot of unlicensed operators out there.

Fitbit Alta HR - a pretty little fitness tracker

Fitbit are the leading manufacturer of fitness trackers (and foraging into the smart watch market with the purchase of Pebble assets last year). The Alta was released a while back and it was the prettiest of Fitbit's offerings. Now comes the Alta HR which is the name suggests, supports heart rate monitoring. Fitbit have managed to squeeze the LED system into the base of the unit (next to the skin) and still keep the same size as the original Alta.

There are various modes and the Alta HR can be set to record heart rate automatically or manually and to background sync etc. The different options will affect battery life, which is about 7 days on a full charge.

The Alta HR will track steps (and a run if you're inclined that way), distance travelled (but it's calculated as there's no GPS), calories and sleep (if you wear it to bed). If you do wear it to bed it will also calculate your resting heart rate as well as show your type of sleep (light, deep, REM and awake).

Though splash proof, it's not waterproof so no swimming or showering. When you remove the unit it should stop trying to read your heart rate, but sometimes it seems to continue to try to read it (the LEDs flicker) for quite some time.

The smarts is in the Fitbit companion app (Apple Health compatible on iOS) and that where most of the information is displayed.

There are a variety of standard bands that can be bought in different colours. They're made of a fairly chunky silicon that 'feels' pretty solid and use a standard pin/hole clasp to close so can easily be adjusted for size.

Fitbit are now selling premium leather bands and even metal bands which turn the Alta HR into bracelet, though they're pretty expensive and as they're solid, heart rate tracking may not work (as the unit may not be snug on your skin).

Fitbit make other trackers that are more functional, but the Alta HR is definitely the prettiest, but it's reasonably expensive at £129 or more for the premium versions. It's a lot compared to something like the Mi Band2 which can be had for about £16 (it's not as pretty) for almost identical functionality and the battery life on the Mi is over a month.

Engie helping people with sick cars

There are quite a few devices out there which connect to your car's OBD port (all modern cars have one, they're usually under the dashboard and provide access to diagnostics about the car).

Engie comes in 2 parts, an app that can be downloaded from an App Store (both iOS and Android versions are available) and the device that plugs into the OBD port (the Android and iOS devices differ). It's possible to download the app for free and set-up an account and order a device through the app (which sends you to the website) or just order the device from the site directly.

Once the device is plugged into the OBD port and the engine turned on, launch the app, search for the device and then connect. The app will then show how the car is performing. There's various modes which can show things like engine temperature, actual trip costs (using real petrol pricing that you have entered), however the real USP of the app is that if there is a fault, Engie will tell you what it is and can then send you to a local garage - the app knows where you are and has a large garage database.

The only downside is that if your car doesn't have any faults, then there's no real advantage to using Engie compared to other OBD devices and other free software that's out there.

The Android device is £14.99 and the iOS device is £19.99 available directly from Engie (it arrives quickly once ordered).

Mi Band2 - a lot of band for not much

Xiaomi are a Chinese company that make stuff - a lot of stuff and they tend to make it well and very cheap. The Mi Band2 is no exception. It's a fitness tracker with a heart rate sensor.

The actual tracker unit is about 4cm long (a bit like a flat capsule) and it fits into a silicon strap. The top is a monochrome OLED display with a single capacitive button on it which allows various modes to be displayed. Underneath is the optical heart rate sensor. Once removed form the strap, it can be charged using the supplied USB charging cable which it pushes into.

There's an accompanying app (both iOS and Android) that sets the Band up (and upgrades the firmware if necessary). The app isn't the best in the world but it shows the number of steps etc. The band is also configured through the app i.e. what's displayed on the band and what notifications it gets. The app can also record activities (running).

The band will autodetect and track sleep, though there are two modes - one uses more battery life and is more accurate as it measures heart rate more often though the basic mode seems to work well too and battery life is very good, so far the band is on 82% charge after a week and a half of wearing so should get a month out of a charge.

Though not recommended for swimming it is IP67 splash resistant so can be used in the shower.

Considering the competition the price should be over £100, however it's available off Alibaba for around £16 including shipping to the UK.

KERV minor update

Use code ETN10 for a 10% discount until the end of March at KERV

There's been a few curve balls, but KERV has arrived

KERV is a ring with an NFC chip embedded so it can be used for contactless payments. Well it's actually more than just a ring as there's a whole payment eco-system behind it.

KERV actually started life on Kickstarter - quite a while back - and there's been a few issues moving the project forward. But it's now possible to actually go on-line and order a ring in a variety of colours (white or black exteriors with varying interior colours).

The ring can be used anywhere that a MasterCard contactless card can be used as it behaves a an M/Chip contactless payment device.

The ring is made from a ceramic called Zirconia, so it's pretty tough (the only things that should be able to scratch it are sapphire and diamond) so it should last a while. When using the ring it needs to be held parallel to the reader (not placed on top with your finger flat i.e. bend your finger and the top of the ring should be parallel with the reader).

The website is available to users which allows activating the ring (a unique 'visual' code is distributed with the ring which is then used to activate it on the site). Users can also activate a virtual MasterCard (you get to print out a copy) which can be used for on-line/over the phone purchases. It's actually pre-paid MasterCard so it needs to be topped up. The ring can then be linked to the card too so only one top up is needed for both.Top-ups can be done using another card or by transferring money into the Kerv bank account with a unique reference generated by Kerv.

Being contactless it also means it can be used on the London Underground just by putting your finger near the reader and 'tapping in'.

The ring currently costs £99.99 from the KERV store if you use code ETN10 you'll get a 10% discount until the end of March.

It should be worn as below: -

Wicked Cool Shell Scripts

The exact title is "Wicked Cool Shell Scripts, 101 scripts of Linux, OS X and UNIX systems, 2nd Edition" by Dave Taylor and Brandon Perry from No Starch Press.

It's been a while since the first version of the book came out (2004) and a lot has changed in the world of UNIX since that time so though many of the ideas from the first version are still valid, it has been updated to take into account systems like macOS and even Windows.

The book is broken into the following sections

• Acknowledgments
• Introduction
• Chapter 0: A Shell Scripts Crash Course
• Chapter 1: The Missing Code Library
• Chapter 2: Improving on User Commands
• Chapter 3: Creating Utilities
• Chapter 4: Tweaking Unix
• Chapter 5: System Administration: Managing Users
• Chapter 6: System Administration: System Maintenance
• Chapter 7: Web and Internet Users
• Chapter 8: Webmaster Hacks
• Chapter 9: Web and Internet Administration
• Chapter 10: Internet Server Administration
• Chapter 11: OS X Scripts
• Chapter 12: Shell Script Fun and Games
• Chapter 13: Working with the Cloud
• Chapter 14: ImageMagick and Working with Graphics Files
• Chapter 15: Days and Dates
• Appendix A: Installing Bash on Windows 10
• Appendix B: Bonus Scripts
• Index

It's a long book at 305 pages, and it's probably more of a reference book for ideas on shell scripting and what you can do rather than reading it from start to finish - though if you're new to the subject, it's probably worth reading Chapter 0 before moving to other chapters.

If you want to get more out of using the command line (on pretty much any UNIX like OS) this could be the book for you.

It's available for purchase direct from No Starch Press for $34.95 Print Book and FREE Ebook or $27.95 Ebook (PDF, Mobi, and ePub), slightly more through O'Reilly (but you can get it through their Safari service) and considerably cheaper through Amazon.

Canon EOS 5D Mark III - The Guide to Understanding and Using Your Camera

This post should have been published a LONG time ago.

O'Reilly are known for their computing books, but they also do technology on other subjects through Rocky Nook. Here's a review on the Canon EOS 5D Mark III - The Guide to Understanding and Using Your Camera from Paul Clark (a professional photographer).

Having worked through the EOS range from 40D, 50D, 5D2 and now to the 5D3, this book has unlocked many things I thought I already knew about Canon digital cameras, even before we get to the new features of the 5D3. It's usefully laid out - in part, going through each menu feature much like the manual does, but adding a lot of When and Why to the How of the manual's basic descriptions. For the first time I really understood what the stopping down preview was all about, and some of the Live View functions. As well as the feature dissection, the book also goes into great detail on some of the really complicated areas that benefit from a chapter to themselves. Focus, and in particular the 5D3's sophisticated autofocus settings are really well explained. I suspect that the actual range of functions is so vast and complex to set up that in the field one would hardly ever have time to do more than a couple of familiar settings, but it's nice to know what's on offer anyway.

The illustrations are clear and plentiful, and the text very readable. I'm a big fan of the style, but if I could pick out one area for improvement it would be a stronger steer towards "what really works" for different shooting scenarios - e.g. which of the many options on focus point selection might work best for a particular settings, or what three custom settings should be the shooter's priority when preparing. There are a few of these "opinions and tips", such as whether the Rate button really offers any value, but there's always room for more in a book like this.

Overall: excellent.

Next time publishing will be in a more timely manner.

Tide, now washing the web

Tide, the on-line business account has now moved into beta. The app can be downloaded from Apple's App Store and it's now possible to access Tide through the web (through it ties into the mobile app and certain things will be authorised through the app).

Tide is a new kind of business account designed for small businesses, it's incredibly easy to sign up (takes under 3 minutes), you immediately get a sort code and account number and you can set-up sub accounts too (so say one is your main business and one for consulting). A card arrives a couple of days later which can be used in ATMs, stores and on the web to pay for things.

As posted before there's an invoicing part of the app and the template can be customised with your logos etc and then if it gets paid, it will tie the payment to the invoice, if it isn't paid, the invoiced person can be automagically reminded from time to time.

All transactions can be tagged (like Sales, Loan, whatever) so easy to see what's happening with your money.

If you haven't signed-up, do it now.

p.s. there are no bank charges as such, though some transactional fees will be taken (like in future when accepting card payments through the app).

AliveCor Kardia band for Apple Watch

AliveCor make things that can read your ECG (EKG) and they've now released the Kardia band which is an Apple Watch strap.

It's easy to install, just press the release buttons on the underside of the Apple Watch, slide the original straps out and insert the Kardia Band ones (the sensor band goes into the one at the bottom of the Watch).

The watch rebooted after the sensor strap was inserted, but it came back fine.

You need to have the Kardia app installed and register an account, then make sure it's installed on the Apple Watch.

Running the app on the phone doesn't do much (it's designed to work with other AliveCor products). Opening the app on the watch then gives you the option of recording an ECG. It's best to have your hand resting somewhere and not moving much (there are options in the app to select which region you're in and whether you're in a 50Hz or 60Hz mains area).

The sensor strap has two sensors, one underneath the strap and one on top. Say the watch is on your left hand, lay that flat somewhere and place the right hand on to it and your finger on the top sensor. Hit record (well you'd probably do that before, you're given some time before a reading is taken) and a countdown timer starts, stay as still as possible until it finishes. After the reading is taken is does some calculations and you can scroll through your ECG and the watch app tells you if it's normal or not (couldn't test the not normal reading) and you can save the results.

It's possible to allow another user to use the app, but the watch needs to be placed on them.

The band costs £99.00 direct from the AliveCor site in both 388mm and 42mm versions. It's a nice quantified self device to have, but expensive and unless you have a heart problem, don't know if really worth it and have to wait to find out how it affects battery life of the watch.

Intel Genuino 101

Well there seems to be a bit of a battle going on in Arduino land, so some of the boards are now known as Genuino (outside of the USA). This board, the 101, is produced by Intel and has a Curie processor (Quark architecture) and a 32bit ARC CPU (not ARM, this is a CPU based on the Argonaut Risc Core - remember Argonaut Software and Jez San), they're both clocked at 32MHz and are 32bit.

Though the board will act like a 'standard' Arduino and can be completely driven through the Arduino IDE, it actually runs an Intel Real Time Operating System (RTOS) that Intel has open sourced and is available through their download centre. When the IDE compiles the code it will do the right things and put the right bits on the correct core.

The 101 should support most UNO and Zero shields, though it's a 3.3V board (though Intel say it will tolerate 5V boards). It's powered either through a dedicated 5V socket or through the USB port. It's NOT microUSB but the older chunky USB B socket.

As well as the 2 cores, there's also a 3 axis accelerometer and 3 axis gyroscope so the board can sense it's spacial direction and movement and it also supports Bluetooth Low Energy (BLE) meaning it can do things like become a beacon or talk to your phone.

The tech specs are

Operating Voltage	3.3V (5V tolerant I/O)
Digital I/O Pins	14 (of which 4 provide PWM output)
PWM Digital I/O Pins	4
Analog Input Pins	6
DC Current per I/O Pin	20 mA
Flash Memory	196 kB (though on-board 384KB rest for RTOS)
SRAM	24 kB (80KB on-board again rest for RTOS)
Clock Speed	32MHz
LED_BUILTIN	pin 13
Features	Bluetooth LE, 6-axis accelerometer/gyroscope

So altogether a nice little Arduino (sorry Genduino) which is pretty fast and pretty compatible.

Pricing varies considerably on-line and it's available from around £16 all the way up to £35, and its available in a variety of kits.

Ring your bell, ring your Oi

Another day, another Kickstarter project. This time it's a bicycle bell made by Australian firm Knog who seems to make a variety of bike accessories (lights, locks, computers, toolsets) and now bells.

The Oi bell is different from other bells, it's circular and fits around the handlebars (it's easier just to look at the picture).

The bell materials available are aluminium, brass, copper, and black (though only copper and brass seem to be available at the moment) and it was also available in Titanium via Kickstarter.

It comes in two sizes, small and large - fitting 22.2mm and 23.8 to 31.8mm handlebars respectively.

The chime is quite pleasant and the design is definitely different.

It's available to buy on-line for €19.99 through the Knog site

Kobo Aura ONE eReader

Kobo have been making eReaders for a while, but have never quite got the market penetration (compared to their book selling rival).

The Aura ONE is a nice unit. It's bigger than the competition (the screen is a 7.8 inch Carta E.ink display with a resolution of 1872 x 1404 at 300ppi). It weighs 226g. So it's about the same size as a paperback book and weighs about the same (195.1 x 138.5 x 6.9 mm). It charges via microUSB and battery life is up to a month (varying by usage of course). The display is backlit and it has a light sensor which will adjust the colour of the front light to suit ambient surroundings (and time of day, so it will reduce the blue content at night - which can potentially affect sleeping technology called ComfortLight PRO).

Several standard book formats are supported, including the most popular ePUP, ePUP3, PDF and MOBI. It can also display several image formats and comic book formats (CBZ and CBR).

The main new feature however is the water resistance, it can survive getting wet (IPX8 i.e. an hour in up to 2 meters of water). If reading in the bath is your fancy, this is the reader for you (or even in the shower, though that's less practical). It's probably usable on a beach too, though salt-water tends to mess things up really badly if it does get into the electronics.

When plugged into a Mac/PC it appears as an external USB disk and books can just be dropped on to the device. Once unmounted (ejected) the books are 'processed' and put into the library ready for reading. Trying both a ePub and MOBI version of the same book (O'Reilly tech book), though the Kobo would read both, the MOBI version caused the Kobi to become very sluggish and reacting to page changes or going back 'home' took a while. The ePub version reacted quickly without problems. PDF's were sluggish too and caused various bits of the screen to flash as pages loaded and moved between bits of the screen.

If you have an account on the Kobo store, it's easy to download a book, just find the one you want, tap on it and it will download.

It's also possible to borrow books from your local library (assuming there's still any left in your area) using the Overdrive service. All you need is a library card and books can be requested. You'll be warned (3 days) when the book needs to be returned, then you can re-request it if you haven't finished it. The list of libraries is available here.

Assuming you stick to ePubs it's not a bad eReader and being waterproof is a nice feature. It's a shame MOBI/PDF aren't handled better.

The Kobo Aura ONE is available on-line for £189.99 which is a lot cheaper the Amazon's top of the range eReader, but a lot more expensive than their basic ones, though it's bigger and more book like. Oddly the Kobo site doesn't have availability at the moment.

Adonit Pixel - it's no pencil (but close)

Adonit have been making styluses for iPads for a while. The latest incarnation is the Pixel (which is slightly longer and thinner than the previous Script so it feels more like a pen). It still uses a 1.9mm pressure sensitive point at the end, but it's been improved so it feel more like a pen on paper.

It has rechargeable battery which is charged via a small USB adapter which plugs into a USB port and then the Pixel can "sit" on that.

It can work with any iPad or iPhone as a dumb stylus, but the magic happens when you power it up and then use it with applications that know about stylus' (there's usually an option is the settings area of the application to enable it).

As it uses Bluetooth it only works with iPhone 5, 5c, 5s, SE, 6, 6 Plus, 6s, 6s Plus, iPad Mini, iPad Mini 2, iPad Mini 3, iPad Mini 4, iPad 4, iPad Air, iPad Air 2 and iPad Pro 12.9 (don't quite know why it won't work with the smaller iPad Pro). Packages that support it are Photshop Sketch, Concepts, Procreate, Illustrator Draw, Autodesk Sketchbook, Astropad, Picture Photo Studio, Goodnotes, Penultimate, Notes Plus, Noteledge Cloud, Noteshelf, Myscrypt Smart Note plus many more (and more being added all the time as Adonis have an open SDK that people can use to integrate the Adonit features into their apps).

In terms of features, the Pixel's nib is pressure sensitive so things like line widths or increased/decreased shading will correspond to the pressure being applied, there are also two short-cut buttons that can be defined within the application (say to change brushes or undo/redo). Supports apps also support palm rejection (you tell it your pen holding style) and that can make a big difference as putting your palm on the screen will normally confuse the app and may apply paint (or whatever's being drawn) where your palm is. This can allow a much more comfortable drawing position without worrying about where your palm is resting.

The only gripe is that if you have a screen protector on your Apple device, it can make it feel a bit squidgy (the screen protector in use has a soft texture, a glass screen protector would fair better).

If you're into drawing or note taking on an Apple device, this could be a useful addition for you.

Amazon stock the Pixel for £79 but it can be had online for £59 if you look (it's also cheaper than the Apple Pencil which is only supported on iPad Pros).

There's a new business bank in town and it'll wash the competition (it's called Tide)

There's a new business mobile first bank which will be launching soon. It's called Tide and it looks pretty good.

Though there are a slew of new banks coming on-line, Tide is aiming for the business market with no fees (they make their money on various services that a banking customer might use and they're not unreasonable).

The first thing to say is it very easy to sign-up. Just present a valid ID to the app and take a photo of it, then clever magic works out who you are (which you confirm) and then it asks what company you're going to use (it looks up your details in Companies House).

You then get an account (a real account number and sort code).

Once set-up you can do all sorts of things through the app, like invoice customers, pay invoices from suppliers etc. When invoicing it can track incoming payments and send out reminders if the customer doesn't pay. If you need to take a credit card payment, it can do that too, just scan the customer card, it will then ask the customers for the CCV (the number on the back of the card) and that's it (there's a fee for handling the payment, that's where Tide take a small percentage), but no card readers to worry about etc.

The service is currently in alpha to a few select customers (the alpha client looks very nice, though the version tested was a sandbox'ed version so not doing live transactions, the real alpha client does the same thing in a live environment) and it will hopefully launch in beta very soon.

Though it's mobile first, all services are also available on-line (web access) and there's a (developing) API on to everything, so if you want to build your own client and offer new services, you'll be able to do so.

If you want to sign-up for access, use this link Tide Preview.

Blink (and the thieves are gone)

There's a new home security security system, it was originally a Kickstarter project and was delayed a long time. But now it's here and it's called Blink.

There's a sync module and then camera units (the system can cope with 10 camera units in total). Currently it all works over WiFi, but as there's an Ethernet port on the sync unit, it's expected that it will be enabled with some future version of the firmware.

Set-up is relatively simple, install the iOS (or Android) app, create an account and then it will look for the sync unit (it initially uses its own WiFi), connect to it and select the WiFi network you want it to work with.

It then asks to set-up the cameras, which is done by adding the number printed inside them (you have to open them to put the batteries in anyway), they then get added (and you can name them) and they also connect to the WiFi network.

The camera install is relatively straight forward too, open the back, put in the batteries, push out the bit of plastic in the hole where the mount goes, put it all back together (snaps), put the mount on, then affix the two sided pad and stick it on a wall (or wherever suits).

Though they're battery powered, they should operate for a year under normal operating conditions (a new software update now takes this to 2 years). The cameras have a motion detection on them (infrared) and also an LED flash (for night time usage) which is VERY bright. If a burglar were to break in, they'd probably be more put off by being blinded rather than a camera being in the room. The cameras can take a photo or video (720p with audio) and the system can be alarmed and when triggered, your phone will notify you and get a video or photo.

People have used the cameras outside, but they're not waterproof so if that's required, mount them somewhere where they'll be protected from direct rain (like under the eaves or similar).

A single sync module and camera costs $99 (available from Amazon.com or directly from Blink), a 2 camera kit is $159, 3 camera kit $219 and 5 camera kit $399. Additional cameras are $70.

Update, all the Blink modules are available from Amazon UK, The sync module with 2 cameras is £189.99 and sync module with 3 cameras is £259.99 and an add-on camera is £89.99.

Watch this space for a new external camera which is coming out in 2017.

Plazmatic X dual beam lighter

There are lighters and then there are lighters, the Plazmatic X dual beam lighter definitely falls into the second category.

The lighter is 7.3cm x 3.6cm x 1.25cm which makes it about twice as high as it is wide (which feels slightly wrong, being used to a Zippo to size), this is probably needed to fit a decent battery and the high voltage electronics.

Amazingly the lighter doesn't use any fuel (no gas or petrol to worry about) as it uses plain old electricity to produce a dual plasma beam. Say lighting a cigarette, you hold it near the beam and suck and the beam bends and quickly ignites the cigarette. Very satisfying experience. It's also mean to be able to light all sorts of other smokables (no judgement here).

The lighter can also be used in all sorts of weather conditions including wind as the plasma beam will still be generated (as long as there's a charge of course).

A full charge will give 50-100 lights (though it's so pretty that it's likely people will just click on the button to see the effect. It charges via a micro USB port (USB cable supplied) and charges to full in about 2 hours.

The lighter comes in various finishes (though they seem to be skins attached to the same base model rather than say anodising the body itself).

The lighter is available directly from the Elementium website for $59.95 (there's free shipping at the moment to the US). This may seem a lot for a lighter, though never having to buy fuel should offset it.

Rate: 9/10 (only because of the case).

Garmin Dashcam 35

The Garmin Dashcam 35 is a little camera that can be mounted on your card dashboard and then as soon as power is applied it will start recording. It's size is 9.43 cm x 4.85 cm x 3.89 cm and it has a 3" TFT LCD display and weighs about 113g.

The supplied mount need to be pushed into the socket on the front of the camera (it takes a fair bit of effort to snap it in) and the mount then attaches to the windscreen with a sticky pad. Unfortunately that means the mount is pretty well permanently attached to the the windscreen as it's pretty strong glue, it's a shame there aren't other types of mount that say attach to a heating grill or some other part of the dashboard that can easily be removed. A bodged mount can work by attaching some sticky tape to the mount and the bottom of the camera and it will just about sit on the dashboard with an unobstructed view ahead.

The system records HD video (1080p or 720p) and will stamp the video with GPS coordinates and the system records in a continuous loop i.e. if it runs out of space it will overwrite older video. The system should come with a 4GB microSD card (though the unit supplied didn't have one) which is enough for about an hour of video. It supports up to 64GB cards.

It also has a microphone which records what's happening in the car!!! There's also an accelerometer which will detect a collision (and start recording if it isn't and log GPS coordinates) which is detected as an "event". However when it's recording an event can be pushing the mount into it or it falling off the dashboard on to the car floor.

There's no software in the box, though Garmin's Dash Cam Player is available for download (for Mac and Windows) through their site. This will show the video and the GPS route next to it (when run it will look for an attached camera or videos on the SD card and import them on to the PC/Mac). The actual video files are MP4 so can be viewed in pretty much any video player. The player shows the route taken, speed and time (there is a pointer on the route that moves as you play the video).

A quite nice feature is that it's possible to select Bing (default)/ Baidu or OpenStreetMaps for the map display. It's also possible to convert any unsaved videos to saved (on the PC/Mac), export GPS positions to a GPX file and take a screen shot.

It's also possible to by a Cyclops subscription from the Garmin store (for various countries including UK/Europe) which will alert the user to speed cameras etc.

Apart from the niggling permanent windscreen mount, it's a nice little unit. It retails for £159 from Garmin, but can be had on-line for at least £20 cheaper.

Misfit Ray, it might actually be the first wearable that actually looks like jewellery

A while back, Misfit released the Ray. Basically a tube with a single LED and straps coming out either side (initially only silicon, which are a bit ugly, but now leather straps are available, which look much nicer - though obviously not made for sports/water). The tube is made from aluminium and comes in Carbon Black or Rose Gold.

Apart from the lack of LED's, the Ray has pretty much the same functionality as the Shine2 and measures steps, activities and sport and works with Misfit Link to trigger actions (and can link to IFTT to trigger pretty much anything).

Progress is tracked by the LED flashing different colours (under 25%, 25%+. 50%+, 75%+ and 100%+ i.e. goal met) and it flashes blue when syncing with the Misfit app over Bluetooth (it supports Bluetooth version 4.1). It will;l also indicate incoming calls, incoming texts and wake-up alarm.

The Shine2 uses a single CR2032 battery while the Ray now uses 3 x 393 button cells (which should also give 6 months usage).

The Ray is also 50m water resistant so can be used for swimming.

Misfit are promising a range of new straps and other accessories so it can be worn, say, as a pendant.

The sport band version retails for £72.87 and the leather for £87.45, not the cheapest units out there, but probably (at least for now) the prettiest.

Speed-up your headless Mac Mini

The Mac Mini is Apple's smallest Mac and though it can be used as a workstation, it's often used as a server for offices/workgroups and even in datacentres. Apple even supplies software to make it function as a server (unsurprisingly called OS X Server - currently v5.0.15 is the release version and the beta variety v5.1 beta 2).

The server software supports various functions including a mail server and even remote Xcode compilations. However sometimes it's useful to remotely access the Mac Mini using Apple's remote desktop so getting a virtual screen on to the unit itself. Unfortunately if it's in headless mode, the on-board GPU is not enabled and all graphics is handled by the main CPU, which can make the system seems extremely slow as the CPU is spending it's time rendering the screen, animations and doing screen refreshes etc.

Now there is a solution to this and Newertechnology have produced an HDMI Headless Video Accelerator (t's about the same size as a small Bluetooth or WiFi adapter) that is plugged into the HDMI port and then the Mac Mini then thinks a screen is attached and thus the GPU is enabled meaning all screen handling is done by the GPU rather than the host CPU and everything runs smoothly again.

The adapter supports a maximum resolution of 1080p (and up to 3840 x 2160 on a late 2014 model). Other models supported are Mid 2010 through to the latest. OS X 10.6.8 is the earliest version of the operating supported (no drivers are required).

It can be found on-line for around £21.99. A really useful little edition if using a Mac Mini in headless mode and accessing it remotely (it's also true for using it for remote animation and anything that uses the GPU).

Techstars London opens applications for next cohort

Techstars has opened applications for their 5th London program which will run from June 20th with the demo day taking place in September.

They will be accepting 10 to 12 teams and interested companies should apply on-line through F6s.

Techstars has some great mentors (there may be some bias here) and some great companies have come out of the program. It's progressed a lot since Springboard days.

Ofcom publishes regulations for 'TV whitespace' tech

Ofcom, the Super Regulator, (in December) published the new regulations for TV Whitespace technology which came into force on the 31st December 2015 allowing equipment that meets the regulations to operate on a license exempt basis.

In the new digital era of terrestrial TV, there are digital multiplexes across the UK, these multiplexes use different channels, so neighbouring transmitters don't interfere with each other, which means there is a lot of potentially unused spectrum in a particular area. Multiplex sit in the UHF band which covers 470 - 790 MHz.

In order to avoid interference with existing (licensed) spectrum users, devices will need to communicate with databases which apply rules, set by Ofcom, to put limits on the power levels and frequencies at which devices can operate. There is also a 'kill switch' function whereby the database can tell a device to stop operating completely if interference is found to be occurring.

The UHF TV band is currently allocated for use by Digital Terrestrial Television (DTT) broadcasting and Programme Making and Special Events (PMSE). Currently, Freeview TV channels are broadcast using up to ten multiplexes. Each multiplex requires an 8 MHz channel. Multiplexes are transmitted at different frequency channels across the country in the frequency range 470 to 790MHz.

Whilst a total of 32 channels each 8 MHz wide are reserved for DTT in the UK, normally only one channel per multiplex is used at any given location. In other words, the majority of channels are unused for DTT transmission at any given location. This is required because high-power TV broadcasts using the same frequency need geographic separation between their coverage areas to avoid interference.

The channels that are not used by DTT at any given location can be used by lower- power devices on an opportunistic basis. This opportunistic access to interleaved spectrum is not new. Programme making and special events (PMSE) equipment such as radio microphones and audio devices have been exploiting the interleaved spectrum for a number of years, and Ofcom issues more than 50,000 assignments annually for this type of use.

Ofcom refer to the spectrum that is left over by DTT (including local TV) and PMSE use as TV White Spaces (TVWS). By this we mean the combination of locations and frequencies in the UHF TV band that can be used by new users, operating in accordance with technical parameters that ensure that there is a low probability of harmful interference to DTT reception, PMSE usage or services above and below the band.

The following organisations have signed contracts and completed qualification to run the white space databases (WSDB): -

• Fairspectrum Oy
• Nominet UK
• Sony Europe Limited
• Spectrum Bridge Incorporated

The 'master' devices that talk to the databases should report their height, if they don't the database will use a use conservative default values for the purpose of calculation of operational parameters i.e. it will use height values that would result in operational parameters that are equal or more restrictive than they would be had the device reported its height.

Though the regulations do not specify an update time (for master devices to communicate to the databases), Ofcom has stated a maximum time of 15 minutes which strikes an appropriate balance between the need to be able to act quickly in the event of interference and limiting the practical burden on databases of maintaining frequent communications with potentially large numbers of devices. This may be revised if found to be unsuitable.

The WSD Regulations apply to the United Kingdom and the Isle of Man. They do not extend to the Channel Islands.

A master device is a device which is capable of communicating with and obtaining operational parameters from a database for the purpose of transmitting within the frequency band 470 MHz to 790 MHz.

A slave device is a device which is capable of transmitting within the frequency band 470 MHz to 790 MHz after receiving slave operational parameters from a master device.

Type A equipment as equipment which has an integral antenna, a dedicated antenna or an external antenna11 and is intended for fixed location use only.

Type B equipment as equipment which has a dedicated antenna or an integral antenna and is not intended for fixed location use.

WSDs must not be used airborne.

WSDs must be configured in such a way that a user is unable to input, reconfigure or alter any technical or operational settings or features of a device in a way which (i) would alter the technical characteristics of the device which are communicated to a database (this includes the master and slave device characteristics), or (ii) would cause the device to operate other than in accordance with master operational parameters or slave operational parameters, as applicable. An example of (ii) would be the antenna gain. If this parameter is set to be smaller than the actual gain of the antenna, then the device could radiate at a higher level than the limit communicated by the WSDB.

A master device:

• must be able to determine its location
• must provide device parameters (defined now as its ‘master device characteristics’) to a database, in order to obtain operational parameters from the database. The device parameters include the location and the technical characteristics of the device listed below. The operational parameters indicate to the device the channels and power levels that it can use, together with other constraints.
• must only transmit in the UHF TV band after requesting and receiving operational parameters from, and in accordance with, operational parameters provided by a database
• must apply the simultaneous operation power restriction (described at paragraph 3.23 above), if it operates on more than one DTT channel simultaneously and the master operational parameters indicate that this restriction applies
• must report back to the database the channels and powers that the WSD intends to use – the channel usage parameters – and operate within those channels and powers.

In addition, where its operational parameters stop being valid, a master device must tell slave devices that are connected to it to stop transmitting and must stop transmitting itself. The operational parameters stop being valid if:

• a database instructs the master device that the parameters are not valid
• a master device cannot verify, according to the update procedure, that the operational parameters are valid.

In order to support more WSDBs Ofcom also intend to publish on our website a machine-readable version of that list on a website hosted by Ofcom so that it can be selected by a WSD through a process known as “database discovery”. Ofcom would expect that list to include those database operators which have informed Ofcom that they are ready to start providing services to white space devices.

It is interesting that Sony is moving into this space, which probably means they will start producing equipment that uses white space technology for short range communication, such as say a PS4 to its peripherals.

Intel Edison, jack of all trades, but maybe master of none

The Intel Edison is a small system-on-chip (SoC) that measures about 35.5 × 25.0 × 3.9 mm (on its carrier PCB) which has a connector on it allowing it to be plugged into other things (it is possible to get the SoC on just the PCB without the edge connector).

The SoC board can then be plugged on to various boards from Intel, one is a breakout board which exposes various pins and has some USB sockets, there's also an Arduino compatible PCB allowing Arduino shields to be used.

The Edison tries to be everything to everyone, but doesn't always succeed. It actually has two processors inside, a dual thread dual core Atom running at 500MHz and a Quark 32 bit micro-controller running at 100MHz. The Atom runs Yocto Linux and the Quark a Real-time Operating System (RTOS).

It has 1GB of RAM and 4GB of Flash, 802.11 a/b/g/n WiFi and Bluetooth 4.0

There's a total of 40 I/O pins that can be configured to be: -

• SD card - 1 interface
• UART - 2 controllers, 1 with full flow control
• I2C - 2 controllers
• SPI - 1 controller with 2 chip selects
• I2S - 1 controller
• GPIO - 12 with 4 capable of PWM
• USB 2.0 - 1 OTG controller
• Clock output - 32 kHz, 19.2 MHz

Intel provide multiple ways of programming the system: -

• Arduino IDE (v1.6+, no longer requires an Intel specific build)
• Eclipse supporting: C, C++, and Python
• Intel XDK supporting: Node.JS and HTML5

There are other environments that also support Edison (in Arduino or direct mode) such as the node.js Johnny-Five system. Node-red can also be installed directly on the Edison and accessed through its web server. Google's Brillo is also an option now.

Running Linux does have benefits if you're into Linux environments as there's lots of packages that can be downloaded for it or indeed built as required.

You'll either love or hate Intel's development environment (XDK).

Integrating Edison into your own projects does give you a lot of flexibility, though the power requirements aren't as low as some other Arduino types (but by the time shields have been added to give the same functionality, power requirements increase with them). In theory it is possible to put the Atom to sleep and have the Quark micro controller do background non CPU intensive tasks and then it can wake the Atom up to do some hard processing or data transfers through WiFi say, but it's not meant to be 'easy' to actually implement.

The basic Edison (just the board) is around £42, on the small breakout board it's about £72 and on the Arduino base it's £96 though on-line pricing varies.

Overall the Edison really does tries to be everything to everyone and it's a pretty powerful computer (well 2), but it may be too generic for lots of things and the variety of programming modes etc can be confusing.

Socksy, get new socks every quarter

Socksy held their relaunch party last night at the Groucho club in Soho.

Socksy is a socks as a service company (SaaS), you sign-up and then get 3 pairs of high quality socks (street, neat or chic) delivered to your door every three months. They come in an A4 box so it will fit through your letterbox and the box can then be used to file papers etc.

The socks are all high quality and though the preferred Socksy method is for the subscriptions, it's also possible to buy them individually.

Socksy Mens' socks are generally knee length which takes a bit of getting used to if your used to wearing ankle length socks, but they're meant to be the 'real deal' and they're not socks if not knee length. Who knew?

If anyone wants to use the service there a 25% discount off the normal £60 per month service, by using code "lucky feet" (without quotes) the subscription fee is reduced to £45 every 3 months, so that's 3 pairs of high quality socks i.e. £15 a pair.

Socksy are also on Twitter , Facebook, Instagram and Tumblr.

Last chance to control your home with nCube

nCube is a home hub that connects to your home network and then allows you to control devices in your home through the nCube app.

It works with lots of home devices such as Nest thermostat, Philips Hue and LIFX lights, sonos music and Belkin WeMo plug-in & lightbulb products.

Protocols supported are WiFI, Bluetooth and Z-Wave.

The device is secure (the phone app must be set-up on the home network) and the nCube device uses a VPN into the nCube cloud services.

As well as being functional the nCube app is designed to be easy to use and has won several design awards.

The nCube Kickstarter campaign finishes in 3 days so get backing, it's still possible to get one for an early bird price of £99 (it will retail for £139).

Ofcom consults on Walkie Talkies, Level Crossings and DECT phones

Ofcom, the Super Regulator, is holding a consultation on Licence Exemption of Wireless Telegraphy Devices.

Walkie Talkies or as they're officially known as Private Mobile Radio (PMR), are allowed to operate in license exempt status in the band 446.0 - 446.2 MHz. Previously this was split into to bands, 446.0 - 446.1 MHz for Analogue PMR446 equipment and 446.1 - 446.2 MHz for Digital PMR446 equipment.

Ofcom is proposing to make the whole band available for both analogue and digital PMR446 equipment, whereby: -

• the band 446.0-446.2 MHz for the use of analogue PMR 446 with a channel plan based on 12.5 kHz spacing where the lowest carrier frequency is 446.00625 MHz
• the band 446.1-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,103125 MHz and 446.10625 MHz respectively
• the band 446.0-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,003125 MHz and 446.00625 MHz respectively as of 1 January 2018
• analogue PMR446 equipment operating in the frequency range 446.1-446.2 MHz should use more robust receivers as specified in ETSI TS 103 236 or equivalent technical specifications

This would allow any device to transmit max 500mW while NO fixed basestations are allowed and the maximum transmit time would be 180s, This would all come into effect in Jan 2018.

Ofcom also wish to change mandated exclusion zones around radio astronomy sites for level crossing radar to that of co-ordinated exclusion zones i.e. level crossing radar in the exclusions zones could be used with the coordination of the Radio Astronomy sites. The methodology, decision and appeal processes to determine whether a device can be deployed in the coordination zone is to be agreed between the rail network operators and the Radio Astronomy service.

The current exclusion zones are

Site	NGR	Exclusion zone
Jodrell Bank	SJ 79650 50950	20 km
Cambridge	TL 39400 54000	20 km
Defford	SO 90200 44700	20 km
Darnhall	SJ 64275 62265	20 km
Knockin	SJ 32855 21880	20 km
Pickmere	SJ 70404 76945	20 km

DECT equipment has been license exempt for a number of years, operating in the band 1880 to 1900 MHz. Currently the document exempting the equipment states that a handset connects to a basestation and it is proposed to just change the to a short range device (SRD) to make it more applicable to handsets that aren't connected to the telephone network.

Stakeholders wishing to respond may do so using Ofcom's on-line form.

Misfit Shine2 - it's not shiny

Misfit have produced the prettiest wearable for a while, the original Shine tracked steps and was one (if not the) first to do automatic sleep tracking. It was a small disk (27.5mm across and 3.3mm high) which contained the electronics and a changeable CR2032 coin cell which lasted for about 6 months. It came with a silicon strap and a silicon magnetic clip so it could be worn on the wrist or clipped on to a t-shirt, bra, shoes, trouser pocket or wherever suited the user. It's also possible to buy socks and t-shirts with a dedicated Shine pocket and a necklace too. It links back to the Misfit app (Android and iOS) using Bluetooth 4.0.

Now the Shine2 is out it's bigger (it's 30.5mm across and 8mm height) and comes in matt black (carbon back as Misfit describe it) and rose gold. It's also 50m water resistant. The original Shine had 12 white LEDs around the edge and the have been upgraded to RGB LEDs, there's also a 'buzzer' inside that can notify you of various things. The battery is still a CR2032 which should last for around 6 months and Bluetooth is now 4.1 which allows for faster data transfers.

The Shine2 can now wake you up by its buzzer (you set the time in the app), the original Shine had the smart alarm feature, but you'd need the phone by your side. It can now also notify you of calls and texts.

The strap and clip unfortunately don't feel as well made as the smaller ones with the original Shine, but then there'll probably be a slew of new accessories for you to spend more money with Misfit.

Having used the Shine2 for a day, sync'ing definitely seems faster, though you definitely notice the size increase.

Still a very pretty wearable compared to most.

It retails for $99.99 from the Misfit Store (they do ship to the UK using DHL so add shipping costs and import duties/VAT).

Ofcom tackles Pirate Radio

Ofcom, the Super regular has published a report on how it has worked with Haringey Council to remove equipment used for Pirate Radio broadcasting from buildings operated by the council. 19 stations were closed in 2014.

Ofcom and Haringey estimate that this has saved the council £90,000 in enforcement and maintenance costs. Ofcom is meeting with other councils on the 3rd of November to report their findings from the Haringey cooperation and if this is rolled out across London could save councils £1m per annum.

Though Pirate radio is illegal it can form a basis for community radio, unfortunately it can cause real issues and NATS has reported 55 incidents of interference from Pirate station. There have also been complaints from emergency services and licensed commercial users.

There are schemes in place for local broadcasters to legally broadcast and Ofcom has even allowed DAB stations to be set-up using off-the-shelf hardware and open source software which means a DAB station can be set-up for around £6,000. These use Linux and efforts from OpenDigitalRadio and commercially available software defined radios.

Pirate radio has been groundbreaking in the past and it will be a shame if all Pirate radio stations disappear, but if Ofcom genuinely allow more open access using local commercial DAB multiplexes maybe it won't matter.

ARM doesn't quite open source M0 processor

ARM, the company that licenses it's CPU technology, is now offering the designs of it's Cortex-M0 for 'free'.

It isn't quite free, but the IP is available to designers to integrate into their own System-on-Chip (SoC) designs pre-commercialisation, along with supporting peripherals. There's then a fast track process to license the IP when the chip goes into production.

The designs will allow prototyping the the CPU and peripherals on a field programmable gate array (FPGA) before committing to actual silicon.

ARM is also supplying access to the ARM Keil MDK (software developer kits) for 90 days so developers can test their designs.

Once a commercial license has been obtained, ARM will provide use of the ARM Cortex-M0 processor IP, SDK, and Keil MDK development tools, along with ARM technical support.

This should allow start-ups who wish to develop specific SoC solutions to utilise the ARM M0 in their designs without having to pay traditional (large) licensing fees upfront.

There's a new smartwatch on the BLOCKs

After a 2 year wait, the BLOCKS smartwatch is now live on Kickstarter. It has a round face and comes in 3 colours (Onyx Black, Marble White, Sunrise Red) with a 360 x 360 colour display with haptic feedback.

Inside it's got quite a lot of technology inside the core itself: -

• Snapdragon 400 CPU
• WiFi supporting 802.11b/g/n
• Bluetooth 4.1 (Bluetooth Low Energy/Bluetooth SMART)
• 512MB RAM
• 4GB Flash (ePOP
• 1.35" fully round display
• Accelerometer / Gyroscope
• Power button
• Microphone
• Vibration (motor)

It runs a (full) version of Android Lollipop (not Android Wear) which gives the core module much more functionality than standard Android based smartwatches. It doesn't stop there as the watch can be upgraded with modules (blocks) which can be thought of as strap links. A large wrist will support 4 blocks, while a more petite wrist should support 3.

Though designed to support extra modules, the watch core (i.e. the main round watch bit) will function by itself and the lowest cost option is just the core and a strap.

The BLOCKS smartwatch is fully compatible with both iOS (v8+) and Android.

The exciting bit is the additional modules, the following are available via the Kickstarter campaign: -

• Extra battery (the main battery lasts about a day and a half, this extends the period by at least 20%)
• Heart Rate module - uses and optical sensor
• GPS module
• NFC Module - may support contactless payment
• Adventure module - it measures altitude, pressure and temperature

Next year the following modules are planned (Phase 2): -

• GSM module - insert a SIM and leave your phone at home
• Fingerprint module - authenticate things, maybe NFC payments
• LED module - a torch?
• Button module - use for emergency alerts or anything else you can think of using a button for

Then at a later date the following modules might come into being: -

• Air Quality module
• Camera module
• Flash Memory module
• Stress Levels module

The smartphone app allows further modules to be purchased (BLOCKstore), customise watch faces and buy watch apps (BLOCKSware?).

The basic BLOCKS core (and strap) starts at $195. The Super Early Bird (sold out) was at $250, the Early Bird (one left at time of publishing) was $260 and the Late Early Bird is $275 which goes up to $285 when all the early birds have gone. All of the later pricing includes for modules and further modules can be purchased for $30. There are also options to purchase multiple units.

BLOCKS has now been fully funded (the campaign launched at 5pm UK time) and has raised over $300,000 of a $250,000 target, that's $300,000 in under 2 hours!!!

New NFC ring, better with twice the NFC

Last week seems to be the week of NFC (Moo launched it's Business Card+ NFC cards, see previous article) and John McLear has launched the second series of his NFC ring.

The original NFC ring was launched on Kickstarter and though the campaign was a success, rings took far longer to arrive than expected due to production difficulties. Now there's a second NFC ring (also launched on Kickstarter, the campaign is active), which is nicer and better than the first.

The new ring is made from ceramic and looks much smarter than the first series. It has TWO NFC inlays based on the NTAG216 NFC chip made by NCP semiconductors. This allows to the ring to be dual use and store both public and private information. Use one NFC chip to store something like a website address and use the other to store secret info which could be used to unlock a phone (and with the appropriate hardware even a house lock etc). The chips work in the 13.56MHz band and can store up to 888 bytes of information (and that info will be held for up to 10 years). The chips support 100,000 write cycles (unlikely people will change the info stored that often, but in a retail environment that could happen).

The ring is laser engraved with the NFC logo on the inside making it easy to differentiate which is the public and private side of the ring.

The NFC supports 3 modes: -

• open, which allows the user to write the data into chip (and also anybody else who might have an NFC writer in the vicinity)
• closed, whereby once set, the data in the chip can never be changed again
• code lock, this allows setting a code and data on the chip can only be set once the code has been verified by the chip

Currently code lock is not implemented in the Android app that accompanies the ring, but it will be in the future.

The early bird price for the NFC ring was £18 (all gone), but it's still possible to pledge £23 and get one (it's possible to order multiples too). It's also possible to get 2 NFC inlays for £5 and 4 for £10 so users can build their own ring designs (the inlays are 20mm by 6mm by 0.2mm).

Unfortunately NFC is only really usable on Android/Windows and Blackberry users (there's lots of programs available to program the chips including ones by NXP themselves). Since Android 5.0 the smart lock application is included in the base operating system so a phone can be unlocked with an NFC tag.

MacOS X/iOS users are once again out of luck as there's no real native support in the operating systems themselves, though 3rd party NFC add ons are available.

In future it may even be possible to pay for goods with the NFC ring utilising contactless payment technology (though it will require addition security so the crew card tokens/keys can be securely stored in the rings).

The Kickstarter campaign ends on the 21st Oct 2015.
