hi folks,

I've just finished my 2nd circuit-bending experience, using an old yamaha pss-190.

Unfortunally this yamaha doesn't have FM chip, so I couldn't use that 270 tutorial someone posted on the yamaha topic (http://www.circuit-bent.net/pss-270-tutorial.html)

Still, I found some nice and noisy bending points, but no pitch resistor. And neither could I control the bending points with pots (I tried almost all of them, from 5k to 1m). Some guy told me that a lot of pcm keyboards need full current to short.

But I found six good bending points, which I turn on/off with toggle switches. These points can make a nice mix and play random noise.

Here's the video: http://www.youtube.com/watch?v=csy5XRvtJTA&e

Now there are these guys waiting to be bent: a casio sa-1, a pense bem multi (a brazilian children computer-toy, very popular on the early 90s) and a furby. Any sugestions?

thanks and sorry for the raw english.

Well, go for full current bends using triggers: normally-open switches, you can trigger a bend a lot shorter than the time it takes to use a switch!
This results in less crashes.

Combining a trigger like this with a pot, can help you as well! This bend should give you a lot of glitches on the sa-1.

What does pcm have to with variable resistance, just try different resistors, and recheck if you wired the pots correctly, using log pots could be a problem?

Furbies are great, they have a lot of complex circuitry inside them and the eyelids, etcetera are all waiting to be bent! I've seen a lot of 'm and destroyed and old one once, but that was before I knew what circuit bending was!

How about that brazillian computer-toy!? Maybe you could post some pictures and/or sounds, if it's like those v-tech talking teachers, it's great stuff to bent. Very Happy

hey alex, thanks for the reply and the suggestions!

actually, I already opened that computer toy and it has some good stuff inside to be bent! here it goes: http://monotonico.files.wordpress.com/2008/05/img-1.jpg

when I finished it I'll post some pics and a video here.

sorry man, I made that quickly in one afternoon and I didn't mark the bending points Sad
