bleghboard
The bleghboard is a WIP handwired ortholinear split keyboard that is BLE-capable due to the Adafruit Feather M0 Bluefruit LE.
Goals
- Modular & Easy-to-Repair
- I break stuff pretty frequently. I'm not sure if that's due to my rough nature or kids or cats or clumsiness, but I need a keyboard that is kind to my hands and simple to repair
- Sturdy
- USB-C
- Bluetooth for wireless and portable use
- Split hands
- Ortholinear
- Reprogrammability
- Cheap & Salvageable parts
Parts
- Wire (duh)
- Adafruit Feather M0 Bluefruit LE
- Some 18650 cell I tore out of a laptop battery
- Some salvaged keyboard switches
- A fat pack of diodes
- 2x TRRS Jack Terminal Blocks (Link)
- TODO: TRRS-friendly IO expander
- MCP23018 as seen on ErgoDox?
- TODO: Male Mini-USB to Female USB-C (because I only want one or zero cables for all the things)
- TODO: Some means of indicating battery power, preferably in time remaining?
Tools
- Soldering Iron (I have a trash Radio Shack one)
- Rosin-Core Solder (Mine is 0.22" Diameter Silver Bearing 62/36/2 also from Radio Shack)
- Computer capable of flashing the firmware
And since I've done all the extremely difficult work, you won't need:
- Breadboard
- Jumpers galore
- Header pins for controller <-> breadboard
- A head full of ways to write terrible C/'duino code
