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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
