Im starting to work on a laser projector. I’ve seen a couple of cool posts on Hackaday and I think it would really fit the advanced activism project. Imagine you could project a message or video 400 meters away on a building you could never get access to. Buckingham palace? MI6?
The setup consists of a laser diode shooting at a rotating set of mirrors. The sync is done by a IR encoder that changes state every time it sees the flag attached to the rotating mirrors.
I’m just starting to get it all assembled. For the moment my aim is to control on line created by one diode. If it works well I’d try to have an array of diodes creating a screen.
