I've always wanted to make an oscilloscope clock or something similar with a really small CRT. Perhaps input some video with the use of something like the Uzebox game emulator.
I found this cool little 5" black and white CRT in the garbage the other day. I though they tossed it because they lost the 12V power supply. I plugged one in, but nothing. I couldn't open it since it was all sealed up with these really wacky screws. Not the little star ones either, something I've never seen before. I basically just took a pair of cutters and cut the top of the case off.
I realized right away what the probable culprit is. These 2 caps have popped. I could try and swap them out and see if it breathes life back into the TV.
The thing that stinks about this TV is that there are no inputs. I could just hack a Raspberry pi or an Arduino into it and generate some simple text of graphics and use it as a clock.
So the question is, does anyone know where to begin in hacking an input into the tube? I know the dangers of CRTs. I've worked on computer CRTs and have disassembled Macintoshes before. I know how to discharge a CRT.
I suppose I could ditch the speaker, and the AM/FM board to trim things down. I just don't know how to go about inputting a video signal. Anyone have any suggestions on where to start? What am I looking for? I'm no stranger to electronics or making my own PCBs. So if I have to make a little video input board to interface with the tube, even better.
