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!

May 16, 2012 - can you add more mosfets and up the voltage that they switch and push more power?

May 16, 2012 - Yes and no. By increasing the voltage, power will increase quadratically, but you will sacrifice audio quality because of the 10-bit ADC on the attiny. The 10-bits are available only at max power.
