DISQUS

tr · 1 year ago

i have a pretty bright green laser pointer, and one thing i've always wanted to do is to measure the spot size that occurs from beam divergence...but like from a mile away. i haven't done it myself with mine, because a) i haven't found a line of sight, 1 mile area b) i have no friends to help me, or who would want to help me, haha.

try to burn (cook?) different types of meat or other random foods around your house. like a cracker, hotdog, small pile of brown sugar, etc.

You should set up a series of mirros (Like in the movie w/Val Kilmer Real Genius) and see if you can redirect the beam and either change it's size, or just shoot it around corners etc.

use a magnifying lens to focus the beam and see if it'll burn something metal, maybe do some laser engraving

Set your sights on the hubble.. use the satellite finder on NASA's pages to locate it... or beg/borrow a high end home users telescope set up the laser at the eye piece and draw a smilly face on the moon. May need some friends to sync up with draw at the same time.
