All the instructions, from how to build the firing mechanism to the open source control software, are available on the site below and while the video clip leaves a bit to be desired for lack of an actual gun (water or otherwise), I still think this is one kickass project. I can't wait to build one and duck while it shoots paintballs at anything that moves. [Sentry Gun via Boing Boing]

Plug-and-play compatible with "X-box" (we assume he means Xbox 360), Wii, PS3 and Windows (Macs are for yankees, not self-proclaimed redneck techies), the Game Gun has an external battery pack that can be pocketed during play. The accelerometers look pretty decent considering the project's homemade, and the gadget really does turn shooter games into a more immersive, Lazer-tag type experience. Pricing hasn't been announced but this kind of awesome probably won't come cheap. [Crunchgear]

Don't count on holding an invasion of them, though. The coil gun—which uses electromagnetic coils configured as a synchronous linear electric motor, accelerating fire metal pieces as it goes through it—needs eight seconds to have enough electric charge. And that's while plugged to the wall. With batteries, it's 90 seconds.

That said, it's quite impressive, knowing that it only took its creator, Daniel Eindhoven, 40 hours to make it. I want. [The Contaminated]

The Army began using tungsten in its weapons to replace depleted uranium, which is also allegedly (but notoriously) nasty stuff. Tungsten is used in missiles carried by drones, the Phalanx anti-missile gatling gun, anti-tank rounds and a lot more. What's crazy is that even as the Army stops using tungsten in training ammo, it's still looking at tungsten as a depleted uranium in other stuff.

On the other hand, it's not like bullets and other weapons, though they might be more advanced technological terrors, aren't designed to horrible things to human beings in the first place. [Danger Room, Image: longhorndave/Flickr]

The Airsoft pellet gun, in this case a 9mm replica, sits atop a Construx base and can be sighted with a webcam and aimed and fired with a Wiimote. It's like a mashup of our favorite things! [The Capacity]

The Shoot and Cook Rifle BBQ Lighter is a 14.5-inch implement that can set pretty much any flammable material on fire. Sure, it's designed to light coals on a grill, but I can think of plenty of uses for a flame-inducing side arm.

Imagine, you're at a bar. A lady needs a light. You reach into your pocket and pull out the Shoot and Cook Rifle BBQ Lighter. She says, "Oh no he's got a gun!!" Bouncers rush toward you. They can't tell if the tiny rifle is real, but these guys aren't taking any chances.

By the time the night is through, you've both had your heart broken and seen what human bone looks like when exposed to air. $10. [Bass Pro Shops via OhGizmo!]

The Alcohol Shot Gun fires 1 oz of delicious booze right into your mouth (or onto your face, as it would probably turn into after a few rounds). It's the perfect way for you to turn a night of drinking into an awkward show of your aggressiveness and homoerotic tendencies. Party on, dudes. [Urban Trend via Slippery Brick]

It's going to be convenient because the Ripsaw MS1, an unmanned ground vehicle that is designed to be easily fixed and replaced. Make them cheap, don't worry about armor—there are no soldiers inside, so who cares—, and just put them on the battlefield by the truckload, ready to destroy and be destroyed. The philosophy is terrifying.

Developed with just $1 million by the Howe brothers in Maine, the light tank is controlled from a modular station that can be fitted in other army vehicles located out of the battlefield. The Ripsaw MS1 is all-terrain, and as you can see in the video, it can jump through obstacles made of concrete at full speed.

Needless to say, the military are excited: Gen. Peter Chiarelli, Army’s vice chief of staff, called it “an amazing piece of gear” when it was presented yesterday at the Army Science Conference in Orlando. You can rejoice too, because soon there will be no soldiers killed in wars. Just the usual collateral damage of innocent civilans. [Howe and Howe via Defense Tech]

The GAU-17, as this gatling gun is called, drops from the belly of the Osprey when needed. The crew chief—not the pilot—uses the gamepad and a targeting monitor to fire it. The targeting monitor—which also corrects targeting automatically for angle and speed—is connected to a sensor which houses a CCD camera, IR camera and laser range finder.

The GAU-17 is not limited in one axis, but covers the entire field of battle, moving all across 360 degrees. However, since the Osprey engines move from horizontal to vertical orientation depending on the maneuver, the targeting software limits the fire range so the rotors can't get damaged. The pilot can also activate a mode that fixes the gun in a forward configuration, allowing for traditional targeting without having to use the gamepad. [Defense Tech]

Yup, you got it: a cartoon robot with a stylized cartoon laser gun pissed off an airport guard so much that Jake had to swap it before flying. He even asked to speak to a security supervisor, who supported the guard and warned Brad not to put the shirt back on or he could be arrested.

A spokesman for the British Airports Authority said "If a T-shirt had a rude word or a bomb on it for example, a passenger may be asked to remove it," and that sounds pretty fair. But this was a cartoon giant gun-toting robot... on a T-shirt, not a detailed photo recreation of a Glock that might be mistaken for the real deal at a quick glance.

Looks like Britain's safe from cartoon robot gun attacks, at least. [The Sun]
