The CRT will be perfect for the not-yet-revealed project he eventually has in mind for it, but since it doesn’t have a traditional RCA input, this meant a bit of hacking (while wearing rubber gloves to prevent shock) to get it working. What he found was that there is a header pin literally labeled as “video in” on the tube’s control board. Taking this at its word, he took out a Raspberry Pi Zero and wired in its “video out” signal. This actually worked the first time, displaying the Raspberry Pi boot sequence, and showing that sometimes things just work right the first time. With a little more hacking, he was also able to hook up a Raspberry Pi 3.
