I started circuit bending this Speak & Read over a year ago, but lost interest in the project... until last week. That's when I decided to finish it off. I even painted it. I so very rarely do that. It must be love, right?
Here's a list of the bends & mods:
1x 'on' repeater switch.
1x tone switch
1x distortion
5x loop/hold switches.
1x glitch switch.
1x master pitch dial.
1x reset button.
Video output.
line output.
line input.
PT2399 delay w/ rate & feedback dials. Overdrive repeats button and slapback switch.
555-based LFO w/ rate, shape & depth dials and blue indicator LED.
2x switches for LFO control of the Speak's pitch and the delay's rate.
TL082 mixer w/ volume dials for the Speak & Read and Input.
386 based amp to drive the speaker w/ 2x distortion/overdrive dials.
I think that's everything.
The Casio SK-1 (well, Concertmate 500) has 21 switches for glitched out beats, an added LTC1799 precision oscillator to control the pitch. A bass boost switch, Drum volume dial, reset button and also a video-output and a whole bunch of flashing LEDs
one of the scattering-like effect spst toggles causes the gradual raise in pitch every time you press ON. i fixed it on mine by finding an alternate lead nearby. awesome though! still mounting all the switches and stuff on my SK1, been too busy with my band to finish it.
