U of M laser mimics helicopter heat signatures to thwart missiles

Researchers at the University of Michigan have developed a new laser-based countermeasure for aircraft, and unlike others we've seen (and we've seen a few) this technology aims to "blind" missiles rather than knock 'em out of the sky. The system uses a mid-infrared supercontinuum laser to mimic the heat signature of a helicopter, and it has no moving parts -- making it rugged enough to last a long time on rotor-based aircraft. The school has even spun off a company, Omni Sciences, to develop the thing, and has received some $1 million in grants from the Army and DARPA to build a second-generation prototype. Of course, questions remain: is it really a wargadget if you can't blow something up with it? And even if it is, where's the fun in that?

DIY photog creates laser trigger for remote DSLR snapping

There's just no two ways about it: the integrated self-timer is easily one of the most amazing technologies to ever be invented. Yeah, we said it. Unfortunately, beeping for ten seconds while a shooter races to get in position isn't always ideal or fun, and that's where isharq comes in. His Arduino-based mod is amongst the most flexible out there for DSLRs, enabling it to morph from a basic laser trigger hack to something that senses heat, movement or sound (just to name a few) and then makes your camera react accordingly. As it stands, his setup triggers his DSLR to snap a shot whenever a laser beam is broken, and if you're eager to see more, be sure to peek the in-action video just past the break. Oh, and the source link holds all the secrets to recreating something like this in your own laboratory.
