How can I power a digital projector from my exercise bike so when you pedal the video plays?
It's for an installation I've made for an exhibition this sunday so I'm stuck for time! I want people to trigger the video (linked above) by cycling the bike..
I suppose I'd like to do this mechanically rather than electronically- rather than be turning the projector on and off all the time I'd like it to be always turned on and when the pedals start turning a piece of cardboard covering the projector lense is lifted, revealing the video.
Would really appreciate any advice! xAoife
