Interesting little Class-D using a ATTiny up

[quad]

I came across a neat little Class-D amp using a cheap 8 pin ATTiny45 microcontroller.
Looks like a nice one to play with.

Old version - but this has a nice video.

Just yesterday I was looking at this micro controller. That reference was from EFY April edition which I received yesterday. Thinking of making many things of this.

Thanks for starting this thread, I feel the core C-programmer inside me is jumping to write some code for this chip.

Interesting , I would not be surprised if many of the dedicated class D chips turned out very close to this albeit a custom made microcontroller. Definitely something to try out though, would cost very little to build.
