Wow! If you're really considering making a PCB design, keep me in the loop and post stuff here. I'm sure I'll have comments. I'd think the biggest stumbling block will be finding/making an enclosure. The 2 trimpots have to be cleverly positioned for screwdriver access...though these tend to be one-and-done adjustments for a given layout.

Stan, you will most certainly be in the loop! I'm entering the schematic into DipTrace now, and then I'll do a trial fit to see what size PCB will work. Since I don't have that relay, and I already got bit by low current contacts, I'll be using the Songle 5V relay with 10A contacts. I may have to improve the 5V supply.
