CRT Badge – Sony Watchman Hack @Raspberry_Pi #PiDay #RaspberryPi
from Cameron Coward via hackster.io
A few months ago I wrote a post for the Hackster blog about Bitluni’s CRT Boy project. I thought the idea of using a tiny CRT for a build was really cool, and on Twitter Emily Velasco (@MLE_Online) pointed out that you can find a used Sony Watchman online for less than $20. So, I ordered one and decided to turn it into a badge!
Eventually, after quite a lot of research and trial and error, I was able to identify the pins I could use to send a composite video signal directly to the CRT. Since the Raspberry Pi Zero W has a built-in composite video output, this new setup is nice and compact. Below, I’ll describe the steps you can follow to do the same.
