OK, so I finally corrected the schematic - it took a while because I discovered a few changes I had made to the prototype which I had forgotten about, so I had to check both sides of the board and make changes to the schematic several times. It is still missing reference designators and some part info but definitely there is enough there to get a very good idea of what is going on. C.U.T. stands for Capacitor Under Test (connects on the third page) I would be happy for any questions or feedback. https://nofile.io/f/XdFAOyByjPQ/Capacitor+Bias+Meter+Feb+17+2018.pdf I apologize that the PDF is 12 MB - since I scanned a hand-drawn schematic it is essentially a large image. I could have used a lower resolution, too. Sean On Fri, Feb 16, 2018 at 12:51 PM, Sean Breheny wrote: > I would release the schematic and firmware as open source regardless of > whether I sold any.
