This week we decided to build lasers. Not just any laser, but one that puts out 100KW pulses of Ultraviolet light. Okay, the pulses only last 1-2ns and it’s hard to burn things with it, but it’s still pretty cool. It’s pretty easy to make from junk, and it uses Nitrogen right out of the atmosphere to lase. Check out the video:

A while back, a friend of ours asked if we could build one these for him:
Since I like a challenge, I went for it. I ended up using the EM-406A GPS module from U.S. Globalsat, a standard Arduino 328 board, a backlit 16×2 character display from Futurlec.com, and the Pololu soft power switch from Sparkfun.com. The code will be cleaned up and posted soon.
Here are some pics of the build and completed project:
