News: WTFoto's Hobo Advice Challenge Winners!

Howdy, hobos! Last week's WTFoto challenge meandered on much like its namesake, the vagrant. We had a couple good submissions that warmed my heart with laughter. I thought my examples were pretty on point, but my confidence is pretty low right now because I failed a recent IQ test. For your amusement, here are those awesome remixes of the Hobo Image Macro!

Making Electromagnetic Weapons: The Theory Behind EMP Generators

This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.

Camera Phone Photo Challenge: 33 Worcester Boulevard

Over the past 10 months the once peaceful city of Christchurch in the South Island of New Zealand has been haunted by a plethora of devastating earthquakes with hundreds of fatalities.

It was a dull, cold day, so I used a monochrome 'film' which captured the sombre mood of a mourning city; this was coupled with underlying parallelisms of an angled shot emulating t...

News: Analog Video Cam + Thermal Printer = Slowest Instant Camera Ever

Sometimes an "analog" result is highly satisfying when the means for producing it is just the opposite. Enter Niklas Roy's "Electronic Instant Camera" project. The endeavor combines an analog black and white videocamera with a thermal receipt printer. The outcome is something in between a Polaroid camera and a digital camera. Like the olden days, the subject must sit still for a quite a while—3 full minutes—as their image is recorded and printed directly on a roll of receipt paper.

News: Robotic Ghost Knifefish Is Born

Researchers at Northwestern University have hatched a robotic replica of the ghost knifefish, an amazing sea creature with a ribbon-like fin, capable of acrobatic agility in the water. The fish is distinctive in its ability to move forward, backward and vertically, but scientists didn't understand its vertical movement until the creation of its robot replica, GhostBot (shown below). They now know its vertical propulsion is caused by two waves moving in opposite directions, crashing into each ...
