Unfortunately, everything I've worked on so far as circuit-bending goes has died, except for one really basic piece where I slowed down a phonics toy. I think I'm getting better, but the last one completely died on me--weirdly, when I was reducing the amount of current going through it. I added a resistor--in the middle of a length of wire, not even soldering to the board--and it croaked :(
Oh, well. If at first you don't succeed, fry, fry again...
