Me Arm and Me Raspberry Pi

What is it?

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.

A #CheerLights Virtual Christmas Tree

What is #CheerLights?

Cheerlights is a IoT based light control system, originally intended to allow social media to dictate the colour of festive lights around the world.

On the back-end there is a feed aggregator which exposes a JSON, TXT or XML API. Continue reading

Word Clock with a Unicorn

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

Inventing with the IoT – Extension Task

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.

Inventing with the IoT – Workshop

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
