kad VS key-ripper

As for switch hole sizes, I haven't designed anything myself but heard ppl use http://builder.swillkb.com/ to design their plates - it's some generator with size standards for switches and stabs.

Not 3d printing, but found this site which can generate files for laser cutting http://builder.swillkb.com/

In terms of workflow: I'm using a generated layout from Plate & Case Builder - swillkb after pasting in the raw data from http://www.keyboard-layout-editor.com/ : if there's a better workflow out there im all ears and open to trying anything new.

Use SwillKB to create layer design files

I design my own key layout and copy paste the raw json file to this site to generate the case and the plates. http://builder.swillkb.com

The only thing is, it's hard to do a plateless design with handwiring - but not many customs are plateless, anyway. You'll need to get a plate cut, but that workflow can be quite streamlined using a tool like Swillkb's builder.

I used this incredible tool to generate the top and bottom .svg files for the switch portion of the plate and a vector graphics editor to make the silly screen bump on the top right. The cost for the plates on this one was around 180USD after shipping but they charge by area so I was at a distinct disadvantage. I wish you luck on your keeb! This project was very fulfilling once all the bugs got hammered out, I hope yours is as well.

If you can't find a plate file, make a QAZ layout with KLE, import it to this plate generator to make a plate file. The thing is, the generated plate file will be without mounting point or holes. If you want more control, use this one, it's more complicated but with more options.

I just swiped it off of here. seeing as it's a custom board and all hahaha.

Nice - a friend and I worked on my keyboard's debouncer and call it "eager debouncing", not sure if there's an official term for it. I agree that it's much better for latency.

Awhile ago I made an remote infrared sending tool so a raspberry pi can control my A/C unit

Since then I made a much slimmer, cheaper, more efficient version based on the ESP32 but I haven't written up much about that.

I also created my own keyboard with firmware in Rust

I've done a bunch of other small one-off projects too.

Good luck! I have an open source keyboard project in KiCad as well, feel free to reference or use anything from it.

Not sure if the author of the post is around, but I guess this is a question for anyone who has designed keyboards: have you ever tried using shift registers for reading all the keyswitch inputs, and is it worth it? Does it mean you don't have to use a diode per switch?

I've designed my own as well but just went with the traditional key matrix with a diode per switch. Works well enough for the current size.

I made my own keyboard layout just the way I want so I would put these caps on that, or replace the stock caps that came with my Filco board.

Twist looks awesome, I'd put it on my key-ripper

You can absolutely run Rust on the pico - I designed a keyboard with Rust firmware which runs on an RP2040. That being said, wireless functionality might not be existent yet in the Rust world for the Pico W, but I'm sure it won't take long to get added.

I looked at the schematic and it seems reasonable. I just completed an RP2040 project with USB C and it works correctly. You can see the project files here
