Thanksgiving Turkey Quadcopter Shenanigans

November 26, 2010 by 9 Comments

The challenge: can you build a flying turkey that drops pumpkin pie bombs? That’s the question that Utah Aerials asked themselves and they did manage to make it happen. Of course they’re not starting from scratch, but adding a little holiday cheer to an existing quadcopter in the form of a spray painted turkey fuselage. The cheapest pumpkin pie they could find was hung from the copter with care, and dumped thanks to a servo motor. Check the video after the break to see if they were able to hit their balding-bullseye or not.

Seems like the wicked witch music should have been the background for that video.

Ubertooth Board For Bluetooth Experimentation

November 26, 2010 by 9 Comments

Ubertooth Zero is the first offering in [Michael Ossman’s] quest for a Bluetooth sniffing and hacking hardware platform. We’ve seen some of his hacks in the past, like the build-in guitar tuner and some pink pager fiddling. The Ubertooth dongle is his original design based around an LPC1758 ARM Cortex-M3 processor paired with a Texas Instruments 595-CC2400-RTB1 to handle the 2.4 GHz RF communications. Looking at the bill of materials shows a very low cost for the components at just under $30 (if you can get your hands on a PCB to mount them on). He’s written firmware as well as host code to help you up start pulling Bluetooth packets out of the air as quickly as possible.

What can you do with this? That’s up to you, but whatever it is you accomplish, we’d like to hear about it.

Roller Curtains With Your Graphics On Them

November 26, 2010 by 5 Comments

[Lenore] added a bit of customization to her office window hangings by fitting roller curtains with custom printed fabric. The treatment seen above is a $20 Enje roller blind from Ikea but that logo is all Evil Mad Science. The weight at the bottom of the fabric uses a friction-fit plastic insert that can be stapled onto new material. Some fusible tape was ironed onto the sides to finish those edges, and the roller at the top has strong adhesive that remains for a second use after peeling off the original material.

A fabric printer was used to produce this rendition of shades. But we’d like to see some conductive thread added for a fabric-based display that can be rolled up when not in use.

Dodecapod To Offset Segway As Futuristic Transport

November 26, 2010 by 35 Comments

Who doesn’t love a 12-legged robot, especially if you can ride it around work? You can watch this one running around the patio with rider perched atop it. The machine translation is a bit crude, but it seem this is based on the wicked walking sculptures of [Theo Jansen]. The rider can shift their center of gravity to control the walker, much like a Segway. We’d bet this makes for a rough ride on anything but a smooth level surface, but we’re fine with indoor use only. After all, you’ll need to be close to a charging station as this boasts 45 minutes of juice when transporting a 165 pound operator. See it scurry after the break.

Cheap Audio Equipment Makes ATM Theft Easier

November 26, 2010 by 17 Comments

ATM information theft is nothing new. Neither is the use of skimmers to gain access to the data. But it’s a little surprising just how easy it has become to hack together the devices using audio equipment. The images above are samples of a skimmer for sale from an Eastern-European do-no-good. It is the magnetic stripe sniffer portion of the attack which captures card data as an audio recording. That is later turned into the binary code that was read from the card. We’re just speculating, but that looks an awful lot like the PCB from a pen recorder, something you can pick up for just a couple of bucks.

Of course this is used in conjunction with a camera to capture PIN data as the second part of the security protocol, but it really underscores the need for new ATM technology. Some skimmers don’t even require retrieval of the hardware, and you never know where the sketchy machines might pop up next.

Hopefully Detect Trolls Before They Devour You

November 25, 2010 by 24 Comments

In the cold and mysterious wilderness of Norway, it pays to be ready for anything–especially heavy-walking trolls. The team at [nullohm] decided to prepare thoroughly for their trek into the woods to witness the Leonids meteor shower by putting together an Arduino-based “troll detector”.

The device is based on the superstition of hammering a steel spike into a tree to keep trolls away from camp. This goes one step further by including an accelerometer and LED indicators so that you can tell exactly what type of troll is just about to feast upon your tender human flesh.

When the detector is installed into a nearby tree, it takes an average seismic measurement and then looks for telltale footfalls. Even if you’re not concerned with perpetuating superstitions, you might find a use for the source code for simple seismic activity monitoring at home to supplement your miniature seismic reflector.

Elder Robots

November 25, 2010 by 8 Comments

It’s always nice to show our appreciation for our elders. Today’s young robots may be whippier, snappier, and go-gettier than their forbears but you have to admit that few of them have the moxie to dust themselves off after 45 years and have a walk around town (although it still wouldn’t qualify for a senior’s discount). George, a British humanoid robot made out of a WWII bomber, was resurrected by his inventor after decades in the garage–and all it took was a little bit of oil and some new batteries. Respect.

George is very impressive, but he’s not the oldest robot by any means. Ever-popular Buddha inspired a Japanese robot some 80 years ago that has recently been updated (pics here)–do robots meditate in solid state?

In a similar aesthetic vein to George, Chinese farmer Wu Yulu made a robotic rickshaw driver, one of his many eccentric projects since the 80s.

Here on hackaday we see a lot of modern robotics, but what about a return to the old school? Next time you have a scrap airplane on hand why not weld together a classic robot, and while you’re at it give your regards to old George.
