This was a build first design later kind of project.
At this point I believe it is physically complete and should be functional.
I might have taken this project as far as I can alone - the real time control firmware for reliable high power regulation is a bit over my head. Anyone out there interested?
All design details will be made available - My goal is 100% open source and open hardware.
