Play DOOM directly from the flash memory of a KB2040 embedded INSIDE THE KEYBOARD!
Press the custom DOOM button to launch!
A secret USB hub mounted inside the keyboard does the trick of allowing both the keyboard and the Adafruit KB2040 KeeBoar connect to your Windows computer over a single USB cable. CircuitPython watches the NeoKey button and launches a tiny ZDoom.exe when pressed. The host computer doesn't need anything installed at all!
DoooooOOOOM
Mechanical Keyboard
A keyboard with enough space inside to tuck away the hub and microcontroller, plus an added special key. Bonus points for embedded trackpad for all-in-one emergency use.
I used the Cherry Touchboard which is available from DigiKey
