As we're certain you know by now, there are fails, and then there are epic fails. This case most definitely falls into the latter category, as Sea Change's shark-deterrent system (affectionately dubbed Shark Shield) was actually bit into by a great white when tested off the coast of South Africa. Reportedly, the device sends out electronic fields that are meant to deter sharks from coming near surfers, but according to the company's CEO, the botched trial was "due to a problem with the electrode's configuration." Furthermore, he noted that the thing is only "guaranteed to work when it's stationary, not when it's surfing in the wave or paddling." Needless to say, the effectiveness of these type devices have now been called into question, and regardless of whether this thing actually works as advertised, the lack of total protection -- you know, while actually surfing -- is enough to make us steer clear.

While we've seen lots of research revolve around battlefield-ready vests, new sensor-studded helmets could be headed to Iraq in order to "measure the shock from explosive devices." Due to mounting concern and a thirst for knowledge about traumatic brain injury (TBI), the US Army awarded Simbex -- the same company involved with Virginia Tech's data gathering helmets -- a contract to further develop technology for use in combat headgear. Furthermore, the firm hopes to "develop an automatic data-collation system" that could potentially relay information to bases or medics via RFID. It was noted, too, that the Army plans on testing Simbex's design along with "several alternative technologies," and the method that proves most useful could be deployed "as early as December of this year."

GETAC's latest rugged laptop does something that most other units simply can't, as it conveniently converts into a tablet while maintaining that beefy stature and war-tested agility. The V100 is fresh out of FCC boot camp, and judging by the documentation, it looks like it's been cleared for civilian handling. Inside the 11.2- x 8.7- x 1.9-inch enclosure sits a 1.2GHz ULV Intel Yonah U2500 Core Duo processor, up to 2GB of RAM, Intel's 945GMS integrated graphics set, a shock-mounted SATA hard drive, gigabit Ethernet, a 56k modem, WiFi, and of course, optional 3G, Bluetooth, and GPS connectivity. You also get your choice of a 10.4-inch XGA or 12.1-inch WXGA screen, a smorgasbord of ports, Windows XP, a 1.3-megapixel webcam, and a magnesium alloy case that shouldn't have any issues with vibrations, drops, shocks, or extreme temperatures. Unfortunately, there's no details concerning price or a planned release date, but we can't imagine a battlefield-ready convertible landing without some sort of premium.

Dell 9400 owner "ViriiGuy" is a PC repair guy by day, human lightning rod by night. His 17-inch laptop seems just dandy, other than a nasty habit of sending off between 19 and 65 volts of AC out of any screw on the bottom of the laptop. Along with the annoying result of making ViriiGuy "feel like a 9 volt battery" to his wife whenever he's using the laptop, the laptop also fried its own RAM and video card. After getting a replacement 9400 from Dell, along with couple more 9400s he was prepping for clients, VG noticed the exact same shocking dilemma on all three laptops. Reports have also surfaced of similar jolt coming out of a Inspiron 6400, and Dell's 17-inchers are mostly based off the same platform, so other Dell laptops of that size could be at risk as well. The latest word is that VG's own problems were solved by springing for a three-pronged grounded power adapter, but since Dell still hasn't fessed up to the problem, or offered up such adapters for free other than in a few isolated incidents, we thought we'd run this by you Engadget guinea pigs valued readers to see how widespread the problem actually is.

Sure, we've got plenty of options to sit in when it comes to rewarding yourself, but what if you've got a mischievous trick-or-treater that really needs some payback for stiffing you in the candy department? Enter Lil' Sparky, the miniaturized (albeit potent) electric chair, handcrafted to scare the living daylights out of anything or anyone who dares to place its behind in it. Rob Cruickshank has officially "put the cute in electrocute" by wiring up a wooden electric chair that's powered by a single 9-volt battery and can deliver the juice to the unlucky participant with just the flip of a toggle switch. While we certainly don't condone the act of channeling unabated voltage through anybody's bones, be sure to peep the video of the electrifying chair in all its sizzling glory just in case the need presents itself.
