1-Bit Music with Atmel
By Ionela Jan 28th, 2009
In the case of a CD was inserted an ATMEL microcontroller, an audio jack and a battery.... The minimum configuration audio possible! This minimal circuit generates music to one BIT.
It is intriguingly, no?

Yes, it is intriguingly
It is actually so intriguingly that I decided to reverse engineer the schematic. It is possible to do this, in some degree, because if you browse the original website the author provides some high-resolution pictures of the device itself. It might be a little more difficult to determine the value of the potentiometers, but this is more theoretical calculations, and you (or I) will also have to make a guess on how the software works.
