A TV Antenna Plug Is a Complete DOOM Console, Battery Included
DOOM Plays From a Nine Millimeter Antenna Plug Screwed Into a Television
RayTriangle built a game console inside a tiny television antenna plug, including its battery. An ESP32-S3 generates the video and audio signals for an older PAL television and runs DOOM.
Two small circuit boards sit on either side of the battery and connect through a flexible cable. The system creates an analog television carrier signal, while a Bluetooth game controller handles input.
The game console has shrunk until it is effectively the antenna plug behind the television. DOOM is on the screen, but the console is almost invisible.
