Ditch that boring mouse for a military-grade trackball

military-grade-trackball

The bad thing about this type of hack is that now [Tomek Dubrownik] needs to cut a hole in his desk to house the thing. He got this military grade trackball working over USB. It’s old, and could be used as a blunt weapon. But as the video shows it still makes a great input device.

He found the hardware on Allegro – a Polish auction site similar to eBay — for just $20. The original circuitry didn’t make a lot of sense, but a bit of probing with the old oscilloscope let him establish connections to the encoders which are read by some TI 54xx parts. Apparently they use the same logic as 7400 parts but are military grade. He chose a ATmega32u4 development board for his replacement control board. That chip has native USB support so the rest is just a matter of passing data like an HID input device. His code even lets him use those pushbuttons to toggle between cursor movement and window scrolling.

[Tomek] translated his post into English after some prompting by friends at the Warsaw Hackerspace. Here’s the original in Polish if you’re interested.

Hacking the R-390A military shortwave radio receiver to transmit as well

hacking-r390a-radio

After getting his hands on this relic [Gregory Charvat] manage to hack it, converting the receiver into a transceiver.

It may be old, but the R-390A is nothing to scoff at. It’s abilities include AM, code, and FSK operation from 500 kHz to 32 MHz. But it is a receiver with no way of transmitting on the same bands. This is where [Gregory's] hack comes into play. He rerouted the variable-frequency oscillator feed inside of the R-390A in order to use his 20M single-sideband unit. Basically what this does is allow him to control everything from the 390, using the microphone from the SSB — along with some switching hardware — to transmit his own messages.

His demo video starts with him making a few contacts using the hacked equipment. He then spends some time at the whiteboard explaning the changes. This portion went over our heads, but it becomes more clear when he cracks open the case and shows the actual modifications.

BigDog throwing cinder blocks

bigdog-throwing-cinder-blocks

It’s as if giving cheetah-like speed to an advanced robot wasn’t good enough. The engineers over at Boston Dynamics must have been thinking to themselves, how can we make this thing even more menacing? The answer seems to be adding a highly dexterous articulated arm that gives the robot the ability to chuck objects as heavy as cinder blocks. We’re not kidding, look at the image above and you’ll see one mid-flight in the upper left. A quick search tells us that block probably weighs 30 pounds!

BigDog is a research project for the US military that we’ve seen navigating all kinds of terrain. It’s a heavy lifter able to carry loads where other machinery cannot. But now they’ve added an appendage that reminds us of an elephant’s trunk. It branches off of BigDog’s body where a quadruped’s neck would be. At the end of the appendage is a gripper that looks much like what you’d seen on industrial assembly robots. But enough talk, click through to see the action video. Oh, and if you didn’t pick up on the cheetah reference we made earlier you’ll want to check out this post.

Military steals idea of anyone who ever tied a cellphone camera to quadcopter

spy-helicopter

Check out the toy this solder is using. It’s a tiny remote-controlled helicopter. The thing comes in a kit that includes a small tablet through which the nose-mounted camera image can be viewed. These are in use in Afghanistan by the UK Military. The purpose is to help protect foot soldiers by allowing them to perform discrete reconnaissance. What would you pay for this type of life saving technology? How does $31 million for 160 units sound? For that price we expect eight propellers and a cinema quality camera.

The drone is manufactured by Prox Dynamics. They’ve been in development since 2008 and you can bet that a lot of that time went into making it “inaudible” which is the main difference we see between this and hobby-built versions. For now you’ll have to deal with trying to make your own since they will only sell to the government.

The best we can do for you when it comes to video of the thing is prototyping footage from 2009 (after the break). If you have a link to a newer clip we’d love to see it in the comments.

Libyan rebels turn toys into weapons of war

scrapyard_weaponry

They say all’s fair in love and war – trust us, you don’t have to tell these guys twice.

With the war in Libya raging on, the rebels have turned to anything and everything to help give them the upper hand. Engineers and engineering students have put aside their work and studies to become the architects of the Libyan revolution. In a school playground-cum-weapons facility people from all walks of life work together creating powerful weapons from scrap parts.

[Rajab], the group’s chief weapons engineer, used to drive trucks for a living. Now he is directing his fellow fighters on how best to re purpose scrap materials and recovered military weaponry into effective killing machines. As you can see in the video below, everything is fair game. Their creations range from pickup trucks fitted with recovered fighter jet machine guns, to a Power Wheels chassis that has been converted into a remote controlled machine gun turret.

It’s amazing the things that can be produced with some scrap materials and a bit of ingenuity.

Spherical military drone coming to a sky near you

spherical_drone

We’re always fascinated by flying drones around here, and this latest creation by Japan’s Ministry of Defense is no exception. The spherical drone, which looks far simpler than this drone we saw several months back, looks pretty benign at first glance. Once it starts moving however, you can see just how slick it is.

Reports say that it can hit a top speed of 40 mph, but it seems that the fun is relatively short-lived, as the drone runs out of juice after about 8 minutes. While it is flying, the drone appears to be incredibly agile and fairly easy to control. The built-in camera isn’t top end, but it looks more than sufficient for general surveillance use.

While we love quadrocopters and all of the cool acrobatics they pull off, there’s something awesome about a drone that can hit the ground at speed, roll, and take off again without incurring any serious damage.

Anyone care to start work on a civilian prototype with a longer battery life?

RSA SecurID breach leads to intrusion at Lockheed Martin

rsa_securid

It looks like Lockheed Martin is the latest victim in what seems to be an endless string of security breaches. This time however, it does not look like a lack of security measures led to the breach. In fact, it seems that Lockheed’s implementation of a widely-trusted security tool was the attack vector this time around.

Last month we reported on the apparent compromise of RSA’s SecurID product, and while many speculated that this intrusion could lead to subsequent attacks, the firm downplayed the breach. They stated that the stolen data was unlikely to affect their customers, but as usual, the problem appears to be far larger than originally estimated.

The breadth of the intrusion is currently unknown, and with both RSA and Lockheed officials keeping mum, it may be some time before anyone knows how serious it is. When military secrets are in question however, you know it can’t be good!
