[sdiy] Delays: how?

[René Schmitz]

Hi MED and all,

there is a delay core (i.e. very long shift register) at my website. Its based 
on an ATMEL 90S1200 controller. You could modify this circuit/firmware to connect 
a bit serial ADC/DAC. I've used a delta modulator copied from a delta lab patent, 
all you need to interface this to the register is to use a levelshifter (40109 
for 5V->15V, 4050 for 15V->5V). The delta modulator and demodulator doesn't 
really qualify as "simple", but at least the parts are easily obtainable and cheap.

Merry Christmas,
 René
