The MeArm has been developed by Ben Gray (aka @phenoptix) and is a laser cut, build it yourself, robotic arm controlled by 4 servos. Once built, just add a controller of some description (micro controller/Arduino, Pi, Beaglebone Black, etc) and drive the servos to move the arm around. You can find out more from Indestructibles article. Mine was purchased from 4tronix. Continue reading
Cheerlights is a IoT based light control system, originally intended to allow social media to dictate the colour of festive lights around the world.
The current cheerlight status
Put the word Cheerlight and a colour in a tweet and you’ve just told light systems around the world the colour they should show. On the website is a list of the currently supported colours.
On the back-end there is a feed aggregator which exposes a JSON, TXT or XML API. Continue reading
A few days back I saw this article about a Word Clock that had been built using at ATmega328P and an 8×8 LED matrix. “Cool” I thought, I have bi-colour one of those in the “toy” box, I might have a go at that.
Around the same time, those pesky pirates Pimoroni were having their #yarrbooty twitter competition. I was fortunate enough to win a few rounds and decided to spend some of my booty on a Unicorn HAT and an A+. The Unicorn HAT is an 8×8 matrix of very bright RGB LEDs.
And low, the Unicorn Word Clock was born Continue reading
If you have not read Inventing with the IoT – Workshop go do so first, otherwise this will make less sense than usual!
As I said in my previous post, I never actually worked with the IoT code before the workshop, so I downloaded it and combined it with my PiDuino code from earlier this week. As a result I have an Internet of Things NeoPixel ring.

CamJam has a lot to answer for; mainly the evaporation of my evenings this past week. During the jam I helped run the “Inventing with the Internet of Things” workshop, I had no idea what it was all about as it was a last minute thing but I know enough Python and the principles of networking to bumble along. The workshop was run by David Whale in conjunction with IoTic Labs
