I need a low cost LED or OLED display of about one inch in size, capable of displaying composite video signals.
I've messed around with viewfinders from older video cameras, but they are black and white, bulky, and worst of all, very fuzzy. The newer cameras I've hacked into have a ribbon style plug that I've been unsuccessful in splicing video signal into (though I did manage to power a few on, or at least get the backlights going). I'm unsure if this is from an inability for the display unit to display the video signal the camera is generating, or my lack surface-mount soldering skills. Does anyone have any links or advice for how to get the newer style video cameras displaying live, unrecorded video from an external source?
I've heard that people have had great success with playstation one screens for displaying video without hacking, but they are much too large for my application. My hope is for the entire unit to be housed in a section of PVC about the size of a PVS14 night vision system (2.5" in diameter by 4" long), with a high-sensitivity camera in the front, disposable lithium batteries mounted in a case on the bottom of the tube, viewfinder at the back, and the wiring, voltage regulators, and switches in the center of the tube.
I've seen stand-alone LCD and OLED panels for cheap (these come to mind: http://www.4dsystems.com.au/prod.php?id=9) but my understanding is that they need some sort of controller unit to input composite video. Is this correct? I have nearly zero programming experience, just messing around with the BASIC STAMP platform, so how much more knowledge would be required in this area to get one of these units up and running? Are there any tutorials on something similar to what I'm trying to do?
I can get commercial night vision in the area of $125, which means that, to be a viable DIY option, the whole unit should come to under $85 or so. With the camera clocking in at about $30, this needs to be a dirt-cheap display.
Thanks for your help
