So, I'm not sure if this is the proper place to post this, but here goes:
While I've been waiting ages of eternal days for my NTRQ NVSRAM bank chips to arrive my mind has wandered back to a previous project of mine, which is a DIY video projector built inside of an old slide projector. Slide projectors are easy to get and very cheap, and their replacement bulbs are also very cheap. I found a Kodak 500 Ektagraph for $4 at the thrift shop and brought it home.
I previously experimented with a stripped down Gameboy pocket LCD, but in relocating the ribbon cable I managed to partially damage the LCD, rendering the experiment useless, even though just knowing that it worked was fun.
So now I have a different screen in mind, a 2.5 inch Audiovox display:
This thing can take a standard NTSC composite input and runs off 12v DC. Removing the backlight should be simple, and then I might also remove the anti-glare layer on the front, assuming it has one.
Today I ran some pretty extensive heat buildup tests to find out whether it would get too hot inside. My very un-scientific method was to tape plastic food wrap to the closed slide aperture, which is where heat buildup would be a problem for an LCD panel. I left it installed in the running projector for over an hour and the plastic didn't melt, so I'm going to assume that it'll be safe for the LCD.
I'm going to post more progress and pictures here as I do this project, and please feel free to leave comments. If this works then my total cost for this video projector will be a whopping $19, not including the dead Gameboy pocket I killed in my first attempt.
