I switched from C to Python for the proof-of-concept for rin. In fact, I might just ditch the hardware idea entirely and try to make rin into a full-featured python program, followed by some sort of web service that runs rin on a cloud instance. Really good software would be more accessible than hardware, and because rin probably won't be too resource intensive, a simple javascript webpage with python in the background with support for multiple users could be very, very cheap, somewhere around the range of $30 USD.
