    I want to make a mini laser text projector at home is this possible and if it is possible could you send me a circuit diagram or something i want to do small as possible. i just want it to project a few letters. I thought with a mini keyboard (like in old electronic dictionaries) when i pressed the button it shows the letter. I mean is this possible to do something like that like in the laser projection clocks which projects the clok on the ceiling or on the wall :D I am waiting for your suggestions :)

    Yes, it can be done using two rotating mirrors.
    You can also do it with one rotating mirror and a single array of LEDs.
