I did the first Rather Useful Seminar of the semester today. Thanks for turning up and being a great audience folks. I was talking about the joys of just "Making Stuff". We had various flavours of coloured lights, the ThingOMatic and my balancing robot. Which promptly leapt off the desk and smashed itself on the floor.
As I said at the time, "If only I had some kind of device which I could use to 3D printa new part to replace the broken one...". In the next couple of days I'll knock out a design and then get Una to print a new chassis. Only stronger.
