hermafrobit

hermafrobit - bitcrusher


the objective of this was simply to make a analog-feel bit-depth reducer, from 8 to 1 bit. also, integrated is a sample-rate selector that goes from (about) 8Khz to a couple of 100hz.

terribly simple design; a preamp (electro-harmonix lpb-1), a/d, bit-selector & d/a. that's it.

schematic:




i got this unit ordered and was told to do a housing that was very "me", so i did.



i was very happy when i found a doll with a male body and a female head in a flea-market. maybe it's not actually a girl-head per se, it might just be terribly androgynous (like it's creator?). though "hermafrobit" sounds nice...



trivia:
due to the rubbery squeezy-friendly material i fastened the main circuit board in the stomach of the doll on screws that pushes the board up with springs. the little psu is small enough to put in one of the arms and she's got the transformer-wire running out from the back of her head.

since poor design is my trademark (or rather, i'm not good enough on electronics.... ..yet!) you can get plenty of digital noise, self-oscillating and other weird sounds out of it. the sample rate selector works a simple filter (duh!).

plans for the future involves doing a modular version with pachable ins and outs, thus being able to patch bit 0's out to bit 6's in etc. also, CV-control of bit depth and sample rate could be nice...

unfortunley i couldn't hear what i was doing while recording these soundsamples, they're decent but definetly not showing the whole potential;

- speech.
- a clean triangle with sample rate sweep
- a tr808 with changes in bit depth and sample rate
