You can use 2 lens to expand the dot in a shorter distance, but brightness does suffer a little bit for each filter the laser has to pass through.
on What specs should the focus lens have? Also, I went to college and stuff. Reply I have personally a ~185mW red laser... it's soo much fun.
I love the idea of a cigarette sized projector though - it'd be a worthwhile challenge to get it down that small :) Excellent instructable!
on Nice project.
If it were actually so, cigarette-pack sized projectors that can throw images many feet would probably be available for $125-300.

The plans published in this instructable are very basic indeed - I've experimented with a few other things but thought it best to keep this article strictly aimed at fundamentals with only the laser being the main burden of cost. 12 years ago
Now they have some LEET lasers. If you're going to eventually try using the laser to illuminate a TFT lcd, you might want to go ahead and try your hand at blending lasers to get a "white" beam out to your LCD. My work has also appeared in ReadyMade, c't – Magazin für Computertechnik, and The Wall Street Journal. This is then combined with a variety of homebrewed refractive media – …

on Well, if you want to experiment with a "blu" laser now, repair parts for the ps3 can be found for 40-50USD via My work has also appeared in I love video projectors, and have used one instead of a traditional TV for almost 6 years now. Reply Is that correct? on I'm not sure what their difficulties were, but their laser projector's not good enough to replace our current system. My work has also appeared in I love video projectors, and have used one instead of a traditional TV for almost 6 years now. If you come on LPF, there are people who have laser power meters to whom you can send your laser, if you pay postage they will test it for you and provide a report.
I have never done this, know little if anything about the optics involved, and have only seen a few laboratory attempts at making this work that succeeded with a purely multilaser lightsource.
