Make a Steampunk "Atomic Disruptor" Raygun from Old Parts
The Atomic Disruptor Raygun is straight out of steampunk fiction. The cool DIY raygun has been put together by Cohophoto entirely from old radio and camera parts. If you are looking for a slice of futuristic fantasy, Cocophoto has illustrated the project on his Flickr photoset. Though short on words, the pictures show the construction details of the gun.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
