Arduino Goes to War
Shown uppermost is the prototype of a handheld artillery spotting device developed as a student capstone project at West Point. The blue board to upper left is pretty clearly an Arduino Mega. You can see, in the near upper corner of that board, where the DC power jack has been desoldered and the pads hardwired to the battery pack. The system, called DemonEye, is now reportedly undergoing field testing.
Lemon Hand Grenades
I took an aesthetics class in college. One of the assignments was to package a piece of fruit in an innovative way. I bought a miniature pineapple, cut off the flower, and screwed the fuse, spoon, and pin from a dummy hand grenade into the top. I got an A. But then, I think, so did everyone else.

Giant Machete-Shooting Slingshot
I love Cory Doctorow’s droll description of this creation almost as much as I love the thing itself:
This handy gentleman has built an (arguably ill-conceived, but nevertheless impressive) rifle-cum-slingshot that fires machetes, should you find yourself with the need to fire machetes.
The handy gentleman in question is YouTuber Jörg Sprave, slingshot enthusiast par excellence. He blogs about it here. [via Boing Boing]
Working Handheld Homemade Pulse Laser Weapon
The claim of penetrating a razor-blade impresses me, although I note the only metal penetration in the video is thin aluminum, which has been painted, possibly so that it will absorb more light energy. There’s also some cool shots capturing the pulsed-laser’s plasma ball in midair.
Post-Apocalyptic Pan Pipes
Bullet casing, shell casing, cartridge case, pan pipes, flute.
