Militarized Computing
Okay, this looks like flat-out fun!
Here are two stories about craming a computer into an Army surplus ammo box. The first article is about a regular PC and the second article is about a Linux machine. Both are fun, though.
I really like the idea of an ultra-portable, but ruggedized, PC. And, what better way to ruggedize a PC than to make conform to MilSpec!?! Anyway, these two projects look like lots of fun, so check them out.
