Ladyada demonstrates how to make your own government made $1,000,000 non-violent(?) flashlight for the much, much lower cost of $250.
"After attending a conference where the $1 million "sea-sick flashlight" (named "THE DAZZLER") was demonstrated by the US Dept. of Homeland Security, we decided to create our own version. For under $250, you can build your own dazzler and we've released the source code, schematics and PCB files to make it easy. A great Arduino project for people who really like blinking LEDs. We also added in a mode selection so you can put it into some pretty color-swirl modes, great for raves and parties!
Yes this project does indeed cause: Nausea, dizziness, headache, flash blindness, eye pain and (occasional?) vomiting! So don't use it on your friends or pets."
