Tri-Solar LED Flashlight: because three panels are better than one

If you've ever been memorized by the eerie glow of a laser diode (that would be everybody, no?), and don't mind hacking up a spare DVD drive in order to craft your own laser-based flashlight, this here project is all you. By extracting the laser diode from an unused DVD optical drive and obtaining an AixiZ Laser Module, a Mini Mag, and an assortment of fairly common tools, the laser that formerly read your flicks can now light your way. Of course, you should realize that beaming any living thing in the eyes with such a device is unsafe (and frankly, downright unkind), but feel free to hit the read link below, check the vid after the jump, and get to work if your trusty flashlight just isn't brightening your
Someone in Homeland Security's R&D department must have a sense of humor, because the agency is hoping to soon deploy an LED flashlight that causes uncontrollable vomiting. The light, which is being developed for DHS at Intelligent Optical Systems, first shines a high-intensity beam to stun the target and then begins flashing a series of pulses that change color and duration -- inducing "psychophysical" effects that that include nausea, vertigo, and vomiting. While the concept isn't that far-fetched -- similar symptoms have been seen in helicopter pilots affected by sunlight strobing through spinning blades -- you've got to wonder how many thousands of dollars have been spent developing a weapon that can be defeated by simply looking away.
Unfortunately for those 4,400 or so owners of the Xenon Aluminum flashlight sold at Sportsman's Warehouse, the recall wagon has come your way, and unless you have no fear of exploding batteries, we'd suggest you power it off at your earliest convenience. Interestingly enough, this case involves more than just a faulty design, as the Panasonic CR123A Industrial Lithium batteries packed within are believed to be counterfeits, and it comes as no surprise that these knockoffs "can overheat and rupture, posing a fire and burn hazard to consumers." So, if you happen to own the six-, nine-, or twelve-volt version of these here devices, it looks like you'll be making an unwanted trip out to Sportsman's Warehouse before long.Although most modern phones can go quite a few hours sans an AC outlet, we understand the need for juice in unexpected emergencies, and while the solar-powered charger does a fair job at high noon, you'll probably need a different approach come nightfall. Tackling two issues in one fell swoop is the cellphone-charging flashlight mod, which not only provides a beacon of light for those dim excursions, but also offers up hand crank recharging abilities for your fading mobile. Of course, hacking your flashlight to pull double duty as a manually powered charger is a bit more complex than just picking up a hamster or bicycle-powered option, but you've got to admit, crafting a makeshift charger with spliced cables and a soldering iron is totally MacGyver-approved. So if you're interested in giving yourself (and your handset) a bit longer life when robotic overlords eventually invade our domiciles, be sure to hit the read link for a video demonstration, and do mind the managerial cat on duty.

Sure, we've heard the heartwarming stories of SMS savings a boy's life and TiVo preventing a man from heading to prison, but this round of "Gadgets Saving Lives" features none other than the token iPod as the center of attention. While Griffin has long since had the idea of using the iPod to power a flashlight-type device, a mushroom hunter (yes, they do exactly as the title describes) resorted to the backlit LCD in his Apple in order to lead rescuers to his location. While enjoying a presumably thrilling evening of picking 'shrooms from the wild brush in Vancouver, Washington with his mother, Pini Nou somehow found himself off the beaten path and lost under a cover of darkness (and wild grass, too). By phoning in authorities and faintly describing his surroundings, troops were able to get close enough to view the white glow emitted from his PMP, and 20 minutes later he was safe and sound, albeit "cold, tired, and aching." So, there you have it kids, the ultimate excuse to get an iPod for the holidays -- safety.
