Recently, I realized that there is no real replica of the Disney Sound Source, yet.
There is the thread "Reversing the Disney Sound Source", but the compatible hardware suggested therein looks quite different.
So I thought I should just give it a shot and quickly threw this together:
It's an ATtiny24 with voltage regulator and RC low-pass filter for the PWM output. The DAC in the original dongle was unfortunately a custom part.
The discrete 22kΩ resistors in the original dongle have been replaced with resistor packs, because there's not enough space in a standard enclosure.
The solder bridges connect the RESET and MISO lines in a way that should permit programming via parallel port.
What do you think? Does this make sense? Would it be fully compatible?
