Latest revxlp prototype is a success*!

* New case tweaks for sizing, the height and fit are great now.
* Moved reset and power closer to the edge, for easier access in the case.
* Half PCBA'd by JLC
* Shorter 2mm standoffs for lower overall height of the build.

* Small copper fill issue, but not a show stopper, and already fixed in git.

Career best. Tied for third at a one round #discgolf tournament while staying in TX!

New revxlp case came in. Just trying to wait patiently for the solder nuts to arrive so I can see how it assembles, but I'm optimistic! #mechanicalkeyboards

"Daddy... I love my burp when I've just eaten enchiladas"

Truer words were never spoken.

First Corne Ultralight (ks-27 switches, power switch, nice!view support) PCBs in for testing, as well as half PCBA'd revxlp PCBs. Next case revision, and solder nuts are en route. #mechanicalkeyboard

Zaphod Lite final protos are validated! Will be OSH soon.

* Runs ZMK
* seeedstudio XIAO family of controllers (BLE pictured)
* adafruit sharp memory display
* Kailh choc v1, MoErgo MCC legend sample keycaps
* TI shift register for extra IO

My life and my work on ZMK is taking an exciting next step: https://petejohanson.dev/blog/new-journey-2022/
A New Journey

Ordered the hopefully last round of prototypes of ZMK Uno https://github.com/petejohanson/zmk-uno/

Changes:

* 3 state toggle switch added
* Power domain indicator LEDs
* TRRS jack moved out of the way of the display
* Optocoupler relocated to avoid physical interference with a header on the Nordic DK.
* Better silk, including QR code/URL.
* Solder jumper option to route SPI to the display, to support sharp memory display modules as well.
* I2C pull up option is now a solder jumper to make more room

JLC is moving at quite the pace on these ZMK Uno protos I ordered last night. Will they get it assembled overnight, you think?
