And thusly were the wise words spake by David Griffith
Somehow I got subscribed to an optics catalog. This got me to thinking.
How hard would it be to cause a laser beam to sweep with the speed and
accuracy to be a substitute for a CRT? The upshot? Take an old terminal
with nasty screen burn. Cut off the gun end of the bottle, clean off the
old phosphor. Apply new phosphor of some kind, then mount the laser
rasteriser where the old gun was. Projecting raster images on the side of
a building would be fun too.
I would rather do vector graphics.. :) I have seen plans on the where
you use the voice coils from two old hard drives with mirrors stuck to
them to bounce the laser onto a wall..
Cheers,
