The Globe’s Smallest TV Console Performs DOOM

We’ve seen loads of recreation console tasks right here, lots of them that search to provide a miniature recreation console. But this one from [RayTriangle] could break a brand new barrier totally — it matches a complete TV recreation console that performs DOOM, together with the battery, into a TV antenna plug.

There’s a sort of antenna plug with screw terminals, initially supposed for matching 300 ohm balanced feeder to 75 ohm co-ax. It offers a tiny mission field if you happen to take a look at it that means, and it’s in right here that the console sits. It’s an ESP32-S3 that talks to a controller by way of Bluetooth, and he’s gone into some element on how the RF for the TV is made. Some intelligent methods corresponding to a look-up desk for the part shifted chroma waveforms for every coloration enable the creation of a very good high quality composite sign by way of a resistor-ladder DAC, and that is modulated in a surprisingly old school means onto a provider offered by the ESP’s clock generator.

The end result as will be seen within the video under is a bit noisy, however we expect that is likely to be fixable with just a little filter magic. It’s designed for PAL TVs with a VHF tuner, however we’re guessing some ingenuity might be introduced into play to make it occur for UHF or NTSC. The {hardware} in the meantime is placed on two boards both facet of the battery, with a versatile PCB becoming a member of the 2.

It’s true that gaming although an analogue RF enter to a TV might be much less frequent in 2026, however we applaud the ingenuity in getting this into such a small house. For some purpose it reminds us of the world’s smallest MIDI synthesizer.
