We excited to see this Raspberry Pi Zero RF Video Modulator on Crowd Supply:
Dust Off That Old TV
PiMod Zero brings old tech back to life by allowing a Raspberry Pi Zero to display color or B&W video – and play audio – on vintage televisions. It provides a super-compact way to watch old movies, play retro games, present digital art, or navigate your operating system using any television that receives standard NTSC broadcasts on VHF channels 2 and 3 (55.25 MHz and 61.25 MHz).
In the past, you would have needed a cumbersome RF modulator box to adapt the HDMI signal from a Pi Zero. Now, with this convenient HAT snapped on top of your Pi Zero, no additional dongles are required. In fact, once the Pi is powered up, the only other cable you need is a piece of coax to connect PiMod Zero to your TV.
Configuring the Raspberry Pi to output composite video and stereo audio to PiMod Zero is extremely simple. Handy scripts and thorough documentation will be available in our GitHub repo.
