 "Freedom Torch" is a cheap device, reproducible and easy to assemble from standard parts, enabling to project messages with light. It is basically a powerful customized flashlight. "Freedom Torch" is a cheap device, reproducible and easy to assemble from standard parts, enabling to project messages with light.

 Experiment with the right size, as you may prefer that instead of being as big as possible your message be as sharp and un-distorted as can be. Find the right size of printing that matches your flashlight by experimenting. Experiment with the right size, as you may prefer that instead of being as big as possible your message be as sharp and un-distorted as can be.

 In our prototype, a lens from a discarded diapositive projector worked best, but anything could work really. Some quality lens is likely to give best results in terms of absence of distortion. Find the approximate distance to which it should fit in front of the lens of the flashlight by experimenting. Keep in mind that //the lens will have to move, in order to adjust focus// to different distances of projection. In our prototype, a lens from a discarded diapositive projector worked best, but anything could work really.

 You need to fit the lens snugly into the tube, but not too snugly so it can practically be moved back and forth. Experiment, and feel free to post your own clever solutions to this problem. You need to fit the lens snugly into the tube, but not too snugly so it can practically be moved back and forth.
