LapBoard

This project turns a laptop keyboard into a USB keyboard for other devices. It is handy when setting up a Raspberry Pi if you cannot find a spare keyboard or are simply too lazy to get one.

Wrapped up my latest custom #keyboard today. It’s a single handed keeb designed exclusively for playing #ArcRaiders . Designed in TinkerCad and #3dprinted on my #Prusa mk4. Then hand painted with Panduro Hobby Acrylics and dusted with weathering powders. Running #kmk on a #seeed Xiao #rp2040. #circuipython #kmk

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

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 ?

Finally got around to play with my Raspberry Pi Pico and the fantastic HF oscillator demo by R2BDY. I added some code to generate Chirped Hell and QRSS FSK-CW with it. A bit drifty without locking it to GPS. This will go on the air (30m) tomorrow! 🙂 https://github.com/RPiks/pico-hf-oscillator/pull/6 #hamradio #qrss #rp2040

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.
