Hi. I'm a newbee & not too electronically literate so please expand your abbreviations to help this dummy. I'd like to build a small simple Infrared still image projector like a photographic slide projector but IR only. It doesn't need to be too powerful as I'll only use it in total darkness to project the image about 3 feet. I'm guessing that some IR LEDs would probably provide enough light but I don't know anything about a suitable reflector or lens or how & where to mount my transparency image in the device. I don't want to modify a stills projector & want something much smaller. Is there something small I could buy & modify the light source maybe ? Thanks for your patience in advance.
