I make keyboards, hydroponics that no one has seen and lots of cool pcb / mass production solutions. Reach out if you want to discuss anything.

  • Not that I’m aware of but the DRC systems should be able to make it pretty clear if there’s track issues.

    There are circuit / electrical simulators but that’s a very complicated solution for keyboard designs that tend to be simplistic.

    Matrix circuit designs are not much to be worried about. If you had a design in question I’m sure someone including myself would be willing to look at it.












  • SK6812 Mini-E (they’re the big legs, but I don’t know the component name difference).

    They can be per key (not supported on ZMK currently) or just treated as up facing underglow. BUT! The biggest concern I’ve had is the realization thaht all RGB boards on the market that use SK6812 in bulk don’t seem to consider the total peak power consumption.

    One color can peak at 12ma at 5v. They’re often ran at 3.3 or 3.7v. 3 colors per led for 36ma per led. So on sofie type boards where there’s ~30 keys per half you’re pulling 1.08ma if you ran the leds at max white. This would be HIGHER if they’re run on 3.3v or 3.7v due to the relationship between wattage and voltage. Yet! They’ve worked fine. I’ve had good success.

    Going forward I’m swapping to SK6805 surface mounted leds. I’ve got the pick and place running, and the goal is to have per key rgb with underglow. That would almost 1/3rd the amperage requirements. Also gives me a little more board space I’m hoping.

    Ideally, I’ll have non-rgb options, up facing perkey rgb, underglow, and up and underglow rgb options (probably 2 independent rgb channels aka underglow has its own data pin). All in either Choc v1, MX, and whatever else I decide to support.

    I’ve got a working “screw” mount solution that works! The problem is with the pcbs fitting super well (model dependent) (I’ve based on the standard dactyl) why bother using lots of screws when a little hot glue does the job. My first versions were wrongly sized and I ended up being extra cautious with lots of extra glue to ensure there’s never a issue with pcbs coming free, but at this point I’ll either cut the number of screw points down, or honestly supply it but not use it myself.

    The nice thing with getting access to production equipement (my designs are all about saving my time in production) you get to save that time too.

    Sorry for the silly long response!


  • It’s resin from JLCPCB. My small resin printer just can’t do a 5x6 sadly. The first transparents I had done was with PETG.

    Sadly, JLCPCB doesn’t do tinted black, but honestly a clear coat with a little black alochol dye probably would do the trick.

    I was blown away with the quality from JLCPCB. It’s not that expensive but shipping hurts. Holes aren’t perfect, but my switch dimensions worked great surprisingly. I need to do a little more work getting the threaded inserts I have fully working (might have to drill potentially because I didn’t expect the oval circles). Their texture really confuses me. I legit don’t know for sure what technology they’re using for their resin prints.
