It's time to Blaze ahead (well Beryl)

Beryl (as was Blaze) have started shipping their new front-facing white light/laser combo now called the Laseerlight Core. It's considerably smaller than the older Laserlight and attaches via a silicon strap that goes around the handlebars. There are two inserts for the clip that attaches to the Core to cope with differing tube widths.

The case is now plastic rather than aluminium and it's an altogether smaller design, though the light is 400 lumens along with the green laser that projects the bicycle shape on to the road.

There are 4 modes Day Flash, Pulse, 100% solid, 50% solid and the laser on or off. The battery should last for 41 hours (according to Beryl).

No idea why the iPhone made the green laser look bluefish, but it's really green.

The original Laserlight cost £125, but the new Core is a much more wallet friendly £69.99 and much smaller so it can easily be taken off the bike and put in a rucksack or bag and not take a lot of space.

Is Twitter on the menu? if not get Twizzy

The macOS Twitter client is dated and hasn't been updated for a while, it also can take up a fair bit of screen space. There are other clients out there, but many don't offer that many more features than Twitter's own.

Now there's Twizzy, it's a neat little app that sits in the menu bar of macOS and clicking it allows sending a quick tweet (can put images etc in there too). There is a window that's around all the time, which shows DMs, but that can just be minimised and kept out the way until needed too.

It's really just a quick post tool, but good to have something without distractions that allows you to post that something just when you need too.

It costs $4.99 from the Twizzy site (inc VAT).

Have a little light in your life

Beryl as was Blaze have released a new light designed for portability. It's called the Pixel.

It's quite small being an oval about 2cm long with a ring of LEDs around the edge and a single push-button in the middle. Surprisingly in this day and age it uses micro-USB to charge and not USB-C (Charging cable supplied). There's also a clear clip that the Pixel oops into. The flip can then be attached to a pocket or belt or using the supplied rubber strap attached to a bike or other mode of transport.

There's also a velcro strap which will allow the clip to attach to a helmet.

There are 4 modes that are accessed using the central button, long press and the Pixel will turn on (by default it is all white). A single press then cycles to all red, the next press goes to pulsating white and finally to pulsating red, then solid white again. A long press will turn the Pixel off. The solid white and red are pretty bright.

Beryl claim 10 hours of use on a single charge.

The Pixel costs £19.99 direct from Beryl.

Linking without Libya (well an alternative), try Poplinks

Many sites want to have short links that point to their content for use on Twitter or other social media accounts. There are quite a few sites already doing this, but do you want you link to be hijacked if the regime say changes in Libya?

There's now an alternative called Poplinks and they have some quite neat features (there's also a free plan so you can trial the service). Though the choice of .io is controversial (but probably for another post) and Poplink is moving to the pool.ink domain soon.

Poplinks allow you to enter a URL that you want the Poplink to point to, the actual link can be named whatever you want i.e. say popl.ink/mysensiblename and then this can be called form a button, an image or Mailchimp.

Custom domains can be used which point the domain to Poplink (i.e. your own domain can be used).

Once the campaigns/links have been set-up, there's a nice dashboard to track it all.

It's quite a useful service and really easy to use and much nicer than supporting the Chocolate Factory or Libya.

There's currently a promotion on which gives 70% off all plans using code POP70OFF, sign-up at Poplink.

When need you're in in need of power get InCharge

There's a lot of rubbish on crowdfunding sites and a lot of projects don't deliver. In August InCharge's campaign finished with the promise of a USB charging cable that actually looked pretty neat.

Two versions were on offer, the dual and all in one. The dual offers micro usb and lightning and the all in one micro usb, lightning and USB-C.

It's quite a clever design.

The image shows the all in one and amazingly one actually arrived today and does exactly what it promised to do. It's really compact and can fit on a keychain, the ends are magnetic to stay closed, but are easy enough to open.

They are still available on Indiegogo, though presumably they'll be available through the InCharge site shortly.

How to make 20 Easy Pies

Well actually "20 Easy Raspberry Pi Projects" is a book from Nostarch Press and takes the user through a variety of projects that can be built around the Raspberry Pi.

  • Table of contents
  • Introduction
  • Primer

  • LEDs
  • Project 1: Blinking an LED
  • Project 2: Pushbutton LED Flashlight
  • Project 3: LED Dimmer Switch
  • Project 4: A Graphical User Interface for a Multicolor LED
  • Project 5: Rainbow Light Strip

  • Displays
  • Project 6: An LCD Reminder
  • Project 7: Mini Weather Forecaster
  • Project 8: Pong with a Sense Hat

  • Sensors
  • Project 9: All-In-One Weather Sensor Station
  • Project 10: Intruder Alarm with Email Notifications
  • Project 11: Gas and Smoke Alarm
  • Project 12: Temperature and Humidity Data Logger

  • Cameras
  • Project 13: Burglar Detector with Photo Capture
  • Project 14: Home Surveillance Camera

  • Web Applications
  • Project 15: Building Your First Website
  • Project 16: Connecting Your Electronics to the Web
  • Project 17: Internet of Things Control Center with Node-Red

  • Games and Toys
  • Project 18: Digital Drum Set
  • Project 19: Make a Game in Scratch: Hungry Monkey
  • Project 20: Wi-Fi Remote-Controlled Robot

  • Appendix A: Raspberry Pi GPIO Pin Guide
  • Appendix B: Decoding Resistor Values

All the projects are built using the Pi, some external hardware and then programming the Pi using Python or Node Red.

You don't really need to fully understand programming and in-depth Python to get the most out of the projects, the book goes through the code and explains what the various code segments do.

Node Red is more complex and also simpler as it runs on the Pi and is accessed via a web browser and then the various actions are all performed by wiring bits together. All the actual programming is done behind the scenes. Some libraries and other bits and bobs have to be installed to support various bits of hardware, but the book goes into enough details of how to do it.

Each chapter ends with some tasks that the user can extend the project and though the basic knowledge of programming in the chapter should give these enough of a background to modify/extend the code, to really extend it, it;'s probably learning Python more fully.

All in all if you want to hook a Raspberry Pi up to some hardware, access the hardware through Python (or Node Red), then this book is no doubt a good starting point. However it is just that a starting point and doing more complex things with both the hardware and Python in particular will require more in0-depth knowledge and a more in-depth programming knowledge.

Saying all that, it's a great start and easy to follow and even with a basic knowledge of Python (just basing code on examples from the book) it should be possible to build all the projects and extend most of them without too much fuss.

CRL Demo Day

It was a hot Thursday evening on the 19th of July at U+I's London HQ. The audience hushed which meant it was the started of the Central Research Labs' Demo Day.

CRL specialises in hardware start-ups and runs an accelerator in the old EMI Vinyl Factory in Hayes (which was also the home of EMI's Central Research Laboratory's where the accelerator took its name from).

There was an intro from Matt Hunter of CRL and then Marcus Shepherd, U+I’s Chief Finance Office and then Hadeel Ayoub of BrightSign and Andrie Danescu of Botsandus who presented their entrepreneurial journeys and vision for the future.

The 5 start-ups that went through the program and they were: -

  • Waalflower - a smart charging solution for tablets/phones presented by Arun Thangavel
  • @waalflower
  • Ignius - a device to keep women safe when leaving work, mainly for the Indian market, founded by Chakshu Saharan.
  • Animaro - a design studio led by Matt Gilbert making an 'animated' solstice clock.
  • Gilaasi - make glasses with an LCD film that can be instantly switched from clear to dark and vice versa worn by Bukki Adedapo.
  • Chip[s]board - an MDF replacement made from potato waste products and fried by Rowan Minkley & Robert Nicoll.

Some really interesting companies there and it's going to be exciting to see what happens as CRL expand to other sites across the UK.

The next generation of built-it-yourself Smart Robot is here and it's Smartibot

There are some very clever people in this world and Ross Atkin is one of them. He's more widely known from the BBC TV program The Big Life Fix (with Simon Reeve).

In the past he did a previous Kickstarter project, The Crafty Robot (now with it's own website), over 4,000 robots were sold on the campaign.

Now Ross has launched the next generation of robot, the Smartibot again with a Kickstarter Campaign.

By backing £1 you'll get a PDF so you can print your own mini Smartibot case, though for £35 (£30 earlybird) you get the main board, 2 motors, a battery box and all the components and all cardboard parts to build teabot, AI Bot and Unicorn.

£60 get you the Genius kit which also includes a LED matrix board and distance and gesture sensor.

The most expensive kit is £100 and includes 3 of everything so all 3 bots can be built and a limited edition shiny version cases (gold AI, rainbow Unicorn and silver Teabot - all numbered and signed).

The AI bot (it's not really Artificial Intelligence, but Machine Learning that runs on your phone - beware it can eat your battery) that can do nice things like track an object and follow it.

The main board can actually control up to 4 DC motors and 10 servos all controlled from an app. Microsoft is also involved which will allow Smartibot to be programmed using their MakeCode system (that can be used to program the Micro:Bit used in schools) using a block language or javascript.

Though Smartibot will launch with the two expansions boards (LED/distance) more are planned in the future.

The kits do come with cardboard (cut-out) cases, but Smartibot can be embedded in anything, including a potato. However cases can be 3D printed or even built out of Lego. Of course Smartibot can also be put into existing toys with electric motors and used to control them, so you could make your RC car and give it some smart brains and make it autonomous.

Don't delay and get your Smartibot now
