You: an 80s-style cyberpunk hacker who's got to spread your video message to the people. Jam this tiny, battery powered video nub shank into a state-of-the-art composite video input of a "television" and run!

Use the QT Py ESP32 Pico to build a stylish vaporwave clock, NTSC SPMTE color bar test pattern generator, or other lo-fi/hi-style video applications.

Thanks to the incredible coding efforts of rossumur, bitluni and marciot, it's possible to generate an analog composite video signal with the original ESP32 chip's 8-bit DACs.

Due to 'creative' uses of the DAC on the ESP32 original chip, this code doesn't work on ESP32-S2, C2, S3 or newer chips. Only the ESP32 as found on the QT Py ESP32 Pico, Feather ESP32 v2, and others build on the original architecture.

You'll need a TV or monitor with a composite video input -- this is nearly always a yellow RCA jack.

Some modern displays have compositve video inputs, but this looks particularly awesome on an old CRT TV!
