The final version of the Concertodrone's build docs is online! Also I've added the CAD files for the front panel and some info on the case design in general.
The Concertodrone is a bent Casio SK-1 I've built years ago, and the build docs are intended to give some insights on how I've made it... and hopefully help some people to build their own!
Well check it out here:

This is really nice work. Can you post about the filter circuit?
