A developer named RayTriangle has fit a TV game console capable of playing DOOM, along with its battery, inside a TV antenna plug. The plug used is the screw-terminal type, normally designed to match a 300 ohm balanced line to a 75 ohm coaxial cable; it serves as a tiny project enclosure.
The console is based on an ESP32-S3 that communicates with the controller over Bluetooth. Thanks to a lookup table holding phase-shifted chroma waveforms for each color, a high-quality composite signal is generated using a resistor-ladder DAC; this signal is modulated onto a carrier taken from the ESP’s clock generator.
Designed for PAL televisions with VHF tuners, the device consists of two boards placed on either side of the battery and joined with a flexible PCB. The picture is somewhat noisy, but it is thought that this could be fixed with a filter.
Why it matters
Projects of this kind provide a concrete example of how the boundary between hardware and software is shifting in hobby electronics, showing that a single microcontroller can both run a game and generate the RF signal a television can understand, without requiring an external modulator. The development is of most interest to amateur electronics makers, retro gaming enthusiasts, and those who want to make obsolete devices such as old PAL televisions functional again; the fact that even the plug itself is used as a ready-made enclosure is an accessible demonstration of repurposing everyday parts for different purposes. The project is not a product announcement but a personal build experiment; as such, it serves as a technical reference for those who wish to undertake similar work. The question that remains open is whether the noise in the picture can truly be eliminated with the proposed filter.
