128x32 OLED screen holder for Kinesis Advantage keyboards

thingiverse

Hi. This is a 128x32 OLED screen holder for the Kinesis Advantage or Contoured keyboards. These are very cheap I2C screens To make full use of it you should use QMK (find a 'Stapelberg' PCB or wire a Teensy 2.0+ manually. DuckDuckGo your friend). Stuff I used ======== * Pattex 100% repair gel (I really like this glue) * Black PLA filament because I could get better detail with it than PETG * 128x32 OLED screen from AliExpress for like really cheap (like less than 2 euro). There are blue(cyan) and white screens for sale Cutting the hole ============ * Remove the original label from the keyboard * Print the sawing template (PLA, 0.2mm, grid fill, no supports) * Use the template and a marker * Then saw the hole, I used a Dremel tool Installing the screen holder ===================== * Print the screen holder (PLA, 0.2mm, grid fill, no supports) * Slide the OLED in the screen holder, use a drop of glue to fix it in place * Glue the screen holder to the case Connecting the OLED screen ====================== The Teensy 2.0+ supports I2C on pins D0 and D1. Unfortunately the Stapelberg controller uses these pins to map key columns. In this configuration I moved the first two column pins from D0 and D1 to E6 and E7 respectively. To use this configuration, be sure remove the connection between pins D0 and D1 and the PCB (desolder, then remove both pins). Then route D0 and D1 from the Stapelberg PCB to Teensy pins E6 and E7 respectively. Now you can use I2C to connect an OLED screen or some other awesome stuff! For more info on how to enable the screen see https://beta.docs.qmk.fm/for-makers-and-modders/i2c_driver and https://beta.docs.qmk.fm/features/feature_oled_driver You still have to do some manual programming to do what you want with the screen. Some ideas: showing the selected layer, showing modifier combinations, showing typing speed etc. I'm working on that, but my keyboard layout is heavily modified, so not useful to many. Finalizing ======== * Print the attached sticker and cut an opening for the OLED screen using the template, to really finish it * Preferably use some only sticker service that offer those very thin metallic sticker (everything white in the picture will be metalic gray)
