[GreenKeys] Jack (K2TTY/K0TTY) Hart's Motor Control Board

[Paul Birkel]

I’m interested Steve.  Please keep me in mind if you do proceed :->!  Recommend that you check into current parts availability to ensure that you have the right footprints in KiCad.

Yes, I have finally come to grips with the issue I was having with what I was seeing on the opto-isolator.  And Nick, K4NYW, sent me some scans of the top and bottom of a bare board so that I could confirm the fact that there was no connection to pin 6 of the H11D1.  Have only used Jack's board an not having done any design work with an opto-isolator, I would have thought there would have had to have been a connection to pin 6.  Without a board handy to refer to, I was assuming (I know!) that the board would have a connection and that there was an error on the schematic that had remained undiscovered all these years.  I guess my breakfast this morning could be the egg on my face! 🙂

 

Not having a bare board for a project in mind, I had the bright idea of trying to improve my Kicad skills and recreate Jack's board in a 2020 edition, or 2021 if I don't get busy.  With full credit to Jack for his design right on the board silkscreen.

 

Anyone interested if I'm successful?
