R/C Hexababy Is Guaranteed To Give You Nightmares

For this week’s hack, [Dino] was working on a mechanical cat toy, but the project fell apart towards the end for some reason or another. With time running out, he had to come up with something on pretty short notice, using whatever he happened to have on hand. Luckily he picks up some seriously weird stuff at the local thrift store and had a disembodied doll’s head kicking around for this last minute project.

Taking a cue from Toy Story’s [Sid Phillips], [Dino’s] doll’s head hexapod is as creepy as it is simple. He had a remote controlled hexapod from RadioShack sitting around, and thought it would be fun to combine it with the doll’s head. He replaced the dolls eyes with a handful of LEDs, which are green as the hexapod retreats, but glow a bright red as it advances towards you. The only way it could be any creepier is if [Dino] added a voice box that plaintively called for “mommy” as the doll crawls around!

It’s a relatively goofy project, but it gave us a good chuckle. The most disturbing highlight of the build is when [Dino] removes the doll’s eyes using a wood drill bit around the 6:00 mark.

If you’re looking to kill a few minutes, be sure to check it out – [Dino’s] work is entertaining as always.

Digital Cootie Detector

July 25, 2011 by Brian Benchoff 19 Comments

Kids love games of exclusion. This usually manifests itself in games of ‘keep away,’ having someone ‘catch cooties,’ or the ever-popular ‘No Brian club.’ [Rob] wrote in to tell us about the digital cootie detector he built. The cootie detector operates on galvanic skin response. It’s actually very similar to an E-Meter, although instead of Thetans this device measures something that actually exists.

Galvanic skin response is a measure of the skin’s conductivity. Skin conductivity changes because sweat glands will be activated when someone is nervous. This is a measure of psychological arousal, making it a great detector for games of exclusion – a kid who doesn’t want cooties will ‘psych themself out’ and give themselves cooties.

Modded Wall-E Becomes A Real Robot

[DJ Sures] got his hands on a plastic Wall-E toy and decided to build a robot that includes a camera, voice recognition, and object tracking. The result is adorable so we’re putting this video before the break:

RC Transmitter Does Everything

July 19, 2011 by Brian Benchoff 56 Comments

[Demetris] sent in a tip about a project he’s working on: an Open Source Remote Control transmitter. This is one of the most impressive looking RC transmitters we’ve ever seen. The OSRC could be great for a small UAV – just get the GPS position from the aircraft and map it with the transmitter’s screen. There’s also support for a video downlink so flying around New York City is possible with a single device.

Take To The Skies With This Flying RC Superhero

July 5, 2011 by Mike Nathan 42 Comments

It’s a bird! It’s a plane! It’s….

A flying RC super hero?

No, you’re not imagining things. Maker [Greg Tanous] loves both RC airplanes and super heroes, so he thought it would be awesome to combine his two loves into one spectacular toy. The RCSuperhero comes in two flavors, measuring 75″ and 57″ tall. The larger plane can be purchased as a kit, but the smaller unit is only available in plan form.

The flying superhero weighs in at just about three pounds, and is constructed from foam, carbon fiber, and various other lightweight materials. When using the recommended motor, the RCSuperhero can be launched from a standing position, doing away with the need for runways. The craft looks to be just as maneuverable as any regular RC airplane, making it easy for any seasoned pilot to pick up the controls and get started.

RC planes are pretty cool, but we’ve got to admit that the idea of a vertically launching, flying superhero sounds like a lot of fun!

Stick around to see [Greg’s] RCSuperhero in action.

Sandbox Game In A Sandbox

July 3, 2011 by Brian Benchoff 21 Comments

The team at Monobanda have been working on a sandbox game called Mimicry that uses a Kinect to read the terrain of a sandbox.

From the teaser video and press release, the eventual goal appears to be controlling both a character in the game and the environment simultaneously. By reading the terrain of the sandbox with a Kinect, the team was able to import that into the game world. The team says the game world is inhabited by tiny virtual characters that, “roll around, jump and glide through the Mimicry world.” Anyone playing Mimicry can create obstacles for these little creatures or build them a race track. The Monobandia team says the point of this game is, “to create your own games.” With a fully editable world and its ‘rolling ball’ inhabitants, we can’t wait to make our own custom Beyblade arena.

Since the release of the Kinect SDK a few weeks ago, we’ve been seeing some really amazing projects that should have been day-1 demos from Microsoft. We’ve been impressed with the projects we’ve seen so far, and can’t wait to see what others come up with next. If you have a neat build, be sure to send it into the tip line.

Check out a video testing the game mechanics after the break.

Enhancing Simple Circuit Kits With Microcontrollers

June 24, 2011 by Mike Nathan 12 Comments

[manuka], aka [Stan Swan] is a teacher in New Zealand who enjoys enlightening his students on the wonders of electrical circuits. He primarily uses “snap connector” circuit kits, sold under the BrainBox name in NZ, for his interactive labs as they can be easily manipulated by pupils of all ages.

While the kits are great, he says that the range of experiments they provide can be a bit limited, so he decided to swap out the kit’s sound module for something far more useful – a PICAXE-08M. The space left by removing the sound module was pretty small, but [Stan] got everything to fit without too much hassle. His modification allows his students to program the PICAXE, as well as utilize four of the uC’s output pins.

Needless to say, the addition of the PICAXE module was a huge hit with his students, allowing them to create far more exciting circuits. [Stan] has been revising his system over the years, adding extra output pins, enabling lamp and motor control, as well as tweaking his setup to respond to IR commands.

We think [Stan’s] work is pretty awesome, and we’re still wondering how this flew under our radar for so long. He says that his students vary from preschool kids to centenarians, so if you’ve got someone that you would like to introduce to the fun world of electronics, we suggest picking up one of these kits and getting to work.

[Thanks Haku]
