DeVry had a hand-cranked projector which Edmund sold surplus for $20 so in the seventies and eighties. They had a pull-down claw and would go in both directions, with a fairly dim lamp.
I have a Speco motion analysis projector that can run on a motor or be hand-cranked... in single-frame or hand-crank mode there is a heat absorbing glass which drops down. And it wouldn't be hard to turn an old B&H 500-series projector into a hand-cranked thing... the hard part would be putting a much lower intensity lamp into it, and rigging up a fan to keep the lamp cool. --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
