Tiny CRT Display

I had an old camcorder that was pretty useless. It used VHS tapes (so it was HUGE), but it also didn’t work properly and would eat the tapes sometimes. I decided to take it apart to see if I could do anything cool with it. I found that the viewfinder was a tiny CRT display. I tried to hook it up externally to use it as a display, but I didn’t know much at this point (I was maybe 13 or 14) and probably fried it. I later read online that a lot of video cameras with old CRT viewfinders just took composite video and power for input. I went to the local freecycle forum and got an old camcorder with a CRT viewfinder. I took it apart and took out the viewfinder.DSC_0374This thing is tiny. I think it’s around 0.5″ across. I figured out the pinout of the driver board and hooked it up to 5v and composite video, and it worked great. I wired up a 5v regulator to a 9v battery clip, as well as a 5v input on a molex connector, and wired on a composite video lead.DSC_0365

My mom was doing a photography contest where the theme was minaturization, so I made a little cutout of a old TV and we took a couple pictures:
