ScottoGame Handwired Keyboard

The ScottoGame is a 42-key ortholinear keyboard with a dedicated action button, split spacebar, 5 function keys, and a 0.96" 128x64 OLED display. The action button is 2.75u as I didn’t want to make it fit perfectly due to 3u stabilizers being harder to source and wanted it to be more prominent. The display simply shows the active layer and profile along with Bongocat as you type. I went with stock Gateron Milky Yellow switches and a YMDK DSA keycap set I had laying around with some pink caps for the function keys.

 

Getting One

If you’re interested in getting one assembled, contact me and we can discuss the components and other details for a commissioned build. However, the files are available for free here if you want to build one yourself.

In addition to the 3D printed case, heat shink tubing, wire, and copper, you'll also need tools along with the following components:

• 1 Arduino Pro Micro
• 42 1N4148 diodes
• 2 2u plate mount stabilizer
• 1 0.96" OLED display
• 11 M2x8mm standoffs
• 24 M2x6mm screws
• 2 M2 heat set inserts
• 42 MX switches
• 39 1u keycaps
• 2 2u keycaps
• 1 2.75u keycap

 

 

Wiring

When looking at the back of the board, the columns (blue) go to the following pins on the controller from right to left: RX1, 4, 5, 6, 7, 8, 9, A3, A2, A1

Then the rows (red) go from top to bottom: A0, 15, 14, 16, 10

In addition to the matrix, you will also need to wire up the OLED display.

• VCC: VCC
• GND: Any GND pin
• SDA: Pin 2 
• SCK: Pin 3

Keep in mind, you can connect anywhere on the column or row to the controller, it doesn't need to just be at the end.

 

Firmware

You can find the firmware files on the qmk_firmware repository or you can compile them online using the QMK Configurator. However, QMK is often slow at getting changes merged and because of that you can find the most up-to-date firmware on the ScottoKeebs Github repository. Also available are the pre-compiled firmware files that you can simply download (right click, save as) and flash using QMK Toolbox: 

default.hex - Default QMK keymap in QWERTY.
vial.hex - Default QMK keymap in QWERTY with Vial configurator support.
scotto.hex - My personal QMK keymap in Colemak.

After flashing vial.hex, you should load the vial.vil configuration file within the Vial application to ensure everything functions as expected.
