I went to the Vancouver Glitch Launch Party last week as my Glitch... which wasn't especially difficult given his taste in clothing. Except for his love of the beautifully geeky LED Sneakers.
So I took on the challenge to construct a pair in real life. I bought myself an Arduino microcontroller, wrote a little software and fired up the hot glue gun. The results were a lot of fun and got a lot of attention.
I've blogged the hell out of the shoes and the development process... mostly to provide an intro to Arduino development but might also be of interest to fellow Glitches.
You can read about it here: intro, parts, hello world, first test, final code, putting it all together, in action, epilogue.
[If you only want to see what they looked like, you probably want to skip over my love of software, hot glue and velcro and get straight to in action !]
