I've mentioned conductive paint before, but did you know there's conductive thread too?
E-textiles have been around for a while. Leah Buechley, an associate professor at MIT and director of the High-Low Tech Group, is a leading expert in this area and has developed the super-cool Lilypad Arduino toolkit. She's got a great tutorial online using basic components and I thought I'd give it a try.
I made this robot using a snap as a switch.
And my favourite – the component dude/tte! This was made by my 11-year old helper. The hook and eye works really well as a switch for this example, and the battery is hidden behind the figure.
Next step, finding more kids to try this out with. I wonder what they'll make?
