Not since the WiFi sniffer built to look like a sniper rifle has there been a project with “Bad idea” stamped so many times over it. Matt from NYC Resistor cased a Sansa 2GB MP3 player inside of a decommissioned training hand grenade.

(There was already something of a bomb scare at NYC Resistor when a box was opened with four grenades in it. Yikes. A discovery like that’ll sure starch your shorts. It was finally figured out that Matt had ordered them.)
