Arduino Controlled NES (2A03) Synth - PART II

This works, I swear.

Last time, we left off with a semi-functioning, proof-of-concept noise-maker. In the interest of eliminating variables, we simply shoehorned a design meant for an Arduino Mega onto our Uno. However, now that we know the circuit and software work, we can move on and add another layer, namely: a set of daisy-chained shift registers.

I've wanted to build an NES synth for some time. I knew there were a few options for writing sequenced tracks for the Nintendo, but nothing that would be as satisfying as hitting a key on a keyboard and hearing a sweet arpeggiated square wave spill out. Rather than try to interface with the entire system via the cartridge slot, I felt the easiest way was to just rip out the CPU and control it with an arduino Uno/Duemilanove.

Its been a long time...

My last post was almost 3 years ago(!).  Sorry about that. Thanks for sticking around and checking back.. If this is the first time you've been here: Hi, I'm Nate.

I'll go into more detail in the next couple posts, but here's a quick overview of some of the things I've been working on:
