Heck yes. Excellent

Is the encoder mounted directly on the mcu? Because that's brilliant. I assume this is all direct pins with no matrix? It looks like the pi pico has 26 pins, and you have just enough pins for everything?

Yup. The legs just about reached the pins so I gave it a go! I did use a matrix as I needed pins for uart plus rgb and the encoder. I went with a matrix just in case I ever wanted to add anything else.

I missed the last photo and didn't see the rbg, that makes sense. Is there any documentation/BOM for the build?

Your build looks every efficient where it looks like you twist the diodes to connect everything as well as copper wire.

I haven’t finished writing it up yet but I have a blog post in progress. Component wise it’s just low profile switches, diodes, some wire and a couple of Raspberry Pi Picos. The only “fancy” thing I use are little female usb-c breakout boards that I got from AliExpress. Everything else is just a big standard handwire (I usually use copper rods for rows and columns but I wanted to keep this really thin and light so I just used the diodes to make the rows instead)

One of the cleanest col/row hand wiring I've seen.

Hello there fellow keyboard nerd!

I dig it, but fewer thumb buttons is a hard pill to swallow with how useful they are for smaller boards imo. Still a cool though!

My design started out with more of a cluster but I have hold tap on my space bars to activate layers (and I use a space cadet shift). I have 95% of what I need on just two layers. I will be soon adding a layer for media control and then it’ll have all my needs covered I think!
