I dont have any video sources or screens so when Ive verified the PIC works I can send it back to you to check out the video. On Dec 2, 2017, at 21:30, Eric Page wrote: Beautiful. It looks like our mux design with a single positive supply should work fine. I'll get the ball rolling on a prototype, which I'll send to Alec to stuff with a programmed PIC. Alec: Should I add a couple of PIC12F683s to my parts order, or do you already have them on hand?

I'm going to order parts first, as I want to measure the inside of the D-Sub backshell before I order PCBs. After looking at the 3D models of the backshell and PCB together, I don't think it's going to fit. It looks like the pin headers will be too tall and the PIC won't be able to be socketed. I'd like to use a right-angle DB-25 connector to lower the board and gain more vertical space, but there are only a few available with flanges to fit a backshell, and those start at $10.60 ea., versus $0.64 for the solder cup versions. Stay tuned...
