[Infowarrior] - DIY 'Dazzler' for $250

[Richard Forno]

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

Our first open source Homeland Security non-lethal weapon project -  
The "THE BEDAZZLER: A Do-it-yourself Handheld LED-Incapacitator".
