This is the schematics and the prototype...
It generates signals (very nice to 1300 hz, acceptable to 10khz) using a N - 2N resistor ladder DAC.
It has been designed to be plugged on 7 contiguous pins (GND, D2, ... , D7).
Using 150ohm resistors its impedence is around 300ohm. It generates 0 to Vcc waves on an open circuit, 0 to Vcc/2 on a 300 ohm Load.
