I designed a 70W bridged amplifier based on the Atmel Tiny (attiny45) micro-controller. To keep the video short, I just gloss over the technical details, especially regarding the firmware. I have more details, including schematic and source code at: http://rdimitrov.info/blog/show.php?entry=Microcontroller%20Class%20D%20Amplifier Enjoy!
