As featured on NYC Resistor, Gizmodo, and the Make blog… and many more..
This is the text of the original NYCR blog post.
One cold day in november members of NYC Resistor received a nondescript box… There were no markings on the box that could identify any specific member at NYC Resistor to which it had been sent. They opened it to find what appeared to be 4 hand grenades.
There was much fear and freak out. But cooler heads prevailed and a phone call was made. “Hey Matt, did you order metal objects of a dubious nature?” “Yes, yes I did.” There was a great deal of internal strife over this particular event as ordering munitions to the space is strictly forbidden. Upon review and discussion it was decided that while purchasing decommissioned training grenades was not in fact illegal in NYC (as far as we know), it was not something we would ever do again. That being said. I immediately set forth on a childhood dream project. I put an 1/8th inch jack into the pin hole for the grenade. It looked GOOD. Totally flush… very pretty. So I decided to run with it. I ran the cabling into the grenade… hacksawed it open. Inserted a Sansa 2 GB mp3 player. And then tried to SMD rework it. This ended poorly as the first sansa basically got burned by the rework station and died. The second I avoided using the rework station and instead recruited bre and his arms for a session of intense soldering onto very tiny solder points.
The results were this functional mp3 player embedded in an old hand grenade, with a pretty awesome interface that works. The mp3 is loaded with legal mp3s bought at the amazon mp3 store. The albums are Kompressor’s. Kompressor does not dance. Brush your teeth!
