Creators! Feel free to tip me off about your keyboard related projects to bring them to 120K readers.

SKZBadHabit made a stand for his aviator connector, but what's even better, we got a follow-up on the evolution of his lasercut keyboard, as well as some new tidbits and photos.

Original photos: here.

New ones: here.

The complete keyboard is laser cut with 3 mm MDF and it's covered by a black foil.

The display is a normal SD1306 Display, and the IBM logo is from an old server and just a stick on.

There is a trackpoint module from an old HP notebook, and it also features a RTC module (Real-Time Clock) so the correct time can be displayed.

In addition, the firmware is a custom one too (not QMK): just a simple Arduino code.

One more tip is the pin extender:

First I had the aviator connectors (20 pin) to connect both halves wire by wire but than I added a MCP23017 which is a digital pin extender for my Arduino Pro Micro and so I only need 4 pins.
