I'm in the process of circuit bending this "Micro Jammer" handheld drum toy. I've made some really cool progress on it, but now it seems like this picky ass thing is going to change its mind every other day!
I've been able to get it into this great warble sound mode that is varied with hand distance to a couple of points/probes...but alas, it goes away! I had the thing in this mode for a few hours last night, but now it's resorted to this random-like garbage mode. The sound output also seems to be worse (distorted) when put back into its "normal" mode of operation. I much prefer the other way it worked.
The kicker is, I have no idea what changed. To my knowledge, nothing has changed in that part of the circuit since last night. In fact, this isn't the first time this has happened!!! Dammit! I don't want to continue with this until I get this figured out! Argh!
