seeing 6 trim pots on a board felt a hair excessive
Wait until you see my relay matrix order switch circuit.

Mine was designed for using the PCB pin version of the rotary but I've just made an alternate that should fit the solder lugs... Or, you could probably clip the eyelets off each pin.Yeah, that would be great! Thanks!
I missed the post where you previously mentioned this board, but just wanna say that looks fantastic! Never heard of that circuit before, but your praise makes me think I better breadboard it up!
yeah, clipping the eyelets seems like it would work fine— the ‘legs’ of the eyelets are pretty long, so even after clipping they’d be plenty long enough to get thru a board.Mine was designed for using the PCB pin version of the rotary but I've just made an alternate that should fit the solder lugs...

I have one of the switches on the way to verify.

Breadboarding it is apparently easier lmao, I can’t figure out why the board isn’t workingI missed the post where you previously mentioned this board, but just wanna say that looks fantastic! Never heard of that circuit before, but your praise makes me think I better breadboard it up!
Oooooooh! sp12t and cmos chips together makes me think… something fun is coming without a doubt, and I think I might have an idea as to what it isJust to follow up, yep, that works just fine. I'm still going to modify the footprint so they'll fit without having to clip anything.

This just for battery status. The preamp itself is my Space Heater design, running a 12AX7. Because I need a 12AX7 in my bass.I don't see a micro tube (6111 for example) in that diagram, or is that diagram JUST for the battery status ...?
I know nothing about Macs but I am wishing you good luck! Hope you can find a worthwhile solution.Anyone have suggestions for a free PCB cad that actually works on Mac in the meantime?
