Tweeting Dinosaur

This project was inspired by the work of Andy Stanford-Clark (@andyc) and Lucy Rogers (@drlucyrogers).  They used NodeRED to control a Maplin Action Dino kit via the Twitter hashtag #wakedino.  When a tweet containing #wakedino is found by the NodeRED script, the motor is started, which in turn makes the dinosaur nod up and down.

I opted to recreate their work in Python using the Tweepy library.  I also wanted to build upon the NodeRed implementation with the addition of sound, and the capturing and tweeting of an image. Continue reading

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


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


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
