Your Laptop Keyboard, On Another Device

I am slowly getting better at soldering, 4 out of 7 successful #MechanicalKeyboard PCBs now - all three of my diode-free #GraphTheory wired keyboard PCB designs have worked (eventually) ⌨️🎊

1️⃣ #RaspberryPiPico #RP2040 ‘Gamma Omega TC36K’ (USB only) http://astrobeano.blogspot.com/2025/08/my-first-self-built-computer-keyboard.html

2️⃣ #ProMicro #nRF52840 BLE ‘Gamma Omega Hesse’ https://astrobeano.blogspot.com/2025/10/hesse-diode-free-bluetooth-keyboard.html

3️⃣ #SeeedStudio #Xiao #SplitKeyboard BLE split Forager ‘Acid’ http://astrobeano.blogspot.com/2025/10/partial-heawood-forager-keyboard.html

#ErgoMechKeyboard #ErgonomicKeyboard

My current success rate with #MechanicalKeyboard PCB soldering is currently only 2 out of 5, well 40% is a pass mark - just.

The #RaspberryPiPico #RP2040 ‘Gamma Omega TC36K’ board worked (an easy build, could probably have socketed it). 💚

One success, one failure with #SeeedStudio #Xiao BLE castellated in Forager ‘Acid’ PCB (some fiddly back pads). 🧡

Two failures with #ProMicro #nRF52840 BLE in ‘Gamma Omega Hesse’ board attempting faux-castellation💔

Just as well custom PCBs are fabricated in batches of five - waiting on spare parts to try again - #LearningByDoing or #LearningByFailing ?

Also, the #Pi5 has been announced. Which is all well and good, and I'm tempted to get one for some home NAS shenanigans. But...

Tell me more about that #RP1 chip.

And then tell me when the successor to the #RP2040 is being released.

They are alive!!!

I soldered all 30 of them, they all work nicely!

These will be some nice pro micro alternatives for mechanical keyboard projects!

They have 32 megabit nand flash, the biggest available at the factory.

Due to the #ChineseNewYear , they forgot to process my stamp hole #gerber update approval, and the order has been sitting for their processing confirmation state for over a week. Glad I checked by them this morning. Awesome!🤦 Currently it's in production. Can't wait to have them on my hands.

I got these as #usbc connectors from China. Got both of the variants just in case. #PCB is going to be 1.2mm thick.
