Circuit Bending Challenge completed! [UPDATED 21Mar08]
I ended up bending 2 of the things I got yesterday for the Circuit Bending Challenge. The driving toy was very straightforward, it had your standard black blob IC inside. I replaced the volume and pitch resistors with pots and added a switch for the 'indicators' sound, since it makes a decent beat. It doesn't sound as good using the 6.5mm output jack, I might need to do something to emulate the speaker better or try a transformer.
The 'black mystery box' was pretty cool to start off with so it didn't need much to take it to the next level. I gave it an RCA out and a switch that puts it into constant burble mode. There were some good pitch up and pitch down points but without re-casing I couldn't use them unless I went for touch contacts and I didn't have anything handy. They way it goes off at random intervals makes it great for doing some dub style bleeps, as I demonstrate below.
I uploaded some .wav files too, but I have to wait for them to make it through the moderation queue before I can link to them.
UPDATE: I finally remembered to post the link to the WAV files.
