In my hacking together of my Arduino-controlled OTA Overdrive mod, you may have noticed how messy it was. Tons of wires everywhere! I'm thinking that, to finalize this mod, I'll need to make my own little PCB. I then though, hey, if I'm going to make a custom PCB, why not build the Arduino right into the board!?! I don't know how to do that, but I figured that I'd give it a try.
One important motivation for me was that, I learn how to build in my own microcontroller (Arduino or otherwise), I could then use that skill to design all sorts of fun new modifications for the Polysix...like making a more flexible LFO, or like adding a set of six wavetable oscillators (one for each voice) to expand the synth's tonal palette. Oh, the fun that could be had!
So, I started by figuring out how to build an Arduino on a breadboard. It's been done many times before by others, but it's the first time that I've ever done it. I was surprised at how simple it was. If you're interested, you can check it out here:
