Andy takes a 1987 Sony Watchman portable CRT TV and transforms it into a working retro arcade system—without modifying the TV itself. Using a Raspberry Pi Pico, custom NTSC video generation, a hand-built RF modulator, and an Atari joystick, he codes an original Space Invaders–style game that broadcasts wirelessly to the Watchman. Along the way, he tackles composite video generation from scratch, resistor ladder DAC design, precise timing with PIO and DMA, and building RF circuitry from a 1985 magazine schematic.
