ISS Hidden (behind)

ISS Tracker

The blame for this little project can be firmly placed at the door of @SouthendRPiJams (aka Andy) after I signed up to be an Exhibitor at the Southend Raspberry Jam on 21st Feb.  He dropped me a DM and the conversation went like this

SRJ:

We’re doing Astropi this jam but the HAT won’t be out.  If you could show some of the equivalent AstroPi hardware and code working to help give people ideas, it would be greatly appreciated.

Me Arm servos wired directly to Pi GPIO (breadboard used for power distribution only)

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.

Attach Motors

ToffeeBot

OK, so not quite the Sheldon Virtual Presence Device from Big Bang Theory but who knows…. maybe my next version?

I have had various bits of robots floating around for a while now and never actually pulled them all together. I’ve made both a Scratch, and a PS3 controlled, Pibrella powered bot which I must blog about one of these days. I also built one from LEGO motors and a SN754410 H-bridge a year or two back, but the motors were old (20+ years) and it didn’t get far. Continue reading

The current cheerlight status

How does it work?

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

WordClock

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
