"Made this on Polaroid Type 665 that "expired" in 1975. Negative was pretty good though. Used a radio controlled shutter device I made from a toy RC car. ISO of film was 80, exposure time 20 seconds, cloudy bright, Polaroid negative was scanned and inverted. http://andpph.com"
"Made from the back end of a Polaroid pack-type camera and fitted with a wood box front carrying the pinhole and capping shutter. It is equipped with a removable remotely controlled rotating shutter made from a toy RC car. See http://www.davidhazy.org/andpph/text-pinhole-remote%20control-shutter.html"
