The Scotto36 is a 36-key split monoblock ergonomic ortholinear keyboard with 15° of angle on each half. For the first time ever I decided to add an 0.91” OLED display so I could have Bongocat right on my keyboard as I type. In the middle of the board is a “mod“ where I took a stem of a switch so I could display my artisans. I went with stock JWK Lil’ Tyke switches as I had tons of them from a prior build. Keycaps are Drop DSA Astrolokeys.
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
- 1 0.91" OLED display
- 36 1N4148 diodes
- 12 M2x8mm standoffs
- 24 M2x6mm screws
- 36 MX switches
- 36 keycaps
Wiring
When looking at the back of the board, the columns (blue) go to the following pins on the controller from right to left: 4, 5, 6, 7, 8, 9, A3, A2, A1, A0
Then the rows (red) go from top to bottom: 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.

Hey Joe.
I may have flashed my micro controller with your colemak layout on accident.
I reflashed to the default QWERT layout by holding down top left key(case is already assembled with caps). all keys are correct but now the display only Shows scotto36. How can i get my bongo cat back?
