Now that the triple whammy of Makerfaire/Toorcamp/school project is over, I now have some time to work on this. I've created a Github repository for it, and I'm in the process of uploading core documentation for the chips I'm using so I have a consistent version of it to work from.

I'm still working out the details of what the analog front end should look like. In an ideal world, I'd have some sort of magical tuneable anti-aliasing and reconstruction filters. In my circuit of the imagination, the input would also have nice low-drift high-impedance programmable gain and the output would have high current drivers. I think I have to give up on most of that simply due to the complexity, size, and expense of implementing a circuit that does all of those things and is also low noise, low distortion, etc. I think I will break this tie in favor of building a circuit of minimal size and providing shield kits that allow users to add things like filters, drivers, and screw terminals. 

Next step is to put together a high-level block diagram that shows the functional blocks of the circuit and how they relate to each other. Then I can actually have an image for the project!
