SudoGlove Gets A Big Software Upgrade

March 26, 2011 by Mike Szczys 11 Comments

[Jeremy Blum] recently finished writing a couple of software packages for his SudoGlove system that turns it into a music controller with a lot of features. We’ve seen the hardware in a previous post and as a goal for this iteration he decided not to alter the hardware or the firmware controlling it whatsoever–making this a PC-side software only hack. It’s nice to see improvement on the original ideas as we feel most of the glove-based projects we’ve covered end up getting thrown in the junk box after the developer’s interest wanes.

After the break you can see and hear a demonstration of the complete system. The front end of application shown ~~was written using Processing and~~ includes a slew of user configurations for each sensor on the glove itself. Under the hood [Jeremy] built on the PureData framework in order to really unlock the potential for translating physical movement into synthesized sound. There is also a visual feedback application which will help you practice your movements, important if you’re giving live performances where each finger is a different instrument. Everything for this project, both hardware and software, has been released under a CC license so check out [Jeremy’s] site if you’re interested in building on part or all of the good work he’s done.

Update: [Jeremy] wrote in with a bit of a correction for our synopsis. The application shown in the video is written entirely in PureData and the visual debugger was written with Processing. The two are standalone packages that don’t depend on each other. He also sent us a link to download the code packages.

Giving “sight” To The Visually Impaired With Kinect

March 16, 2011 by Mike Nathan 27 Comments

NAVI

We have seen Kinect used in a variety of clever ways over the last few months, but some students at the [University of Konstanz] have taken Kinect hacking to a whole new level of usefulness. Rather than use it to control lightning or to kick around some boxes using Garry’s Mod, they are using it to develop Navigational Aids for the Visually Impaired, or NAVI for short.

A helmet-mounted Kinect sensor is placed on the subject’s head and connected to a laptop, which is stored in the user’s backpack. The Kinect is interfaced using custom software that utilizes depth information to generate a virtual map of the environment. The computer sends information to an Arduino board, which then relays those signals to one of three waist-belt mounted LilyPad Arduinos. The LilyPads control three motors, which vibrate in order to alert the user to obstacles. The group even added voice notifications via specialized markers, allowing them to prompt the user to the presence of doors and other specific items of note.

It really is a great use of the Kinect sensor, we can’t wait to see more projects like this in the future.

Stick around to see a quick video of NAVI in use.

Fly Like Superman Using The Force

infinity_simulator

At one point or another, who hasn’t had a dream in which you could fly, simply by thinking about it? [Yehuda Duenyas, aka XXXY] is currently working on a project at Rensselaer Polytechnic Institute which can allow you to do just that.

As part of a thesis project dubbed the “Infinity Simulator“, he has constructed a system that allows people to fly about using the elaborate rigging system at RPI’s Experimental Media and Performing Arts Center. His project allows users to glide through the air, walk up walls, and otherwise live out their flying fantasies, with mere thoughts.

An EEG headset is placed on the user, along with other wearable sensors which enhance the audio and visual experience of the person in flight. With enough concentration, the rigging system sweeps people off their feet, sending them soaring anywhere their mind desires. It sounds a bit like pretending to be Superman while using The Force to us, however the installation is described on the EMPAC web site as a “live-action stunt show crossed with a video game.” Either way, sign us up!

Hopefully we will see some video of the completed project in the near future, but in the meantime keep reading to see a behind-the-scenes preview of the flying rig in action.

Clap To Remove This Brassiere

February 14, 2011 by Mike Szczys 71 Comments

Like some strange manga come to life, you can remove this brassiere with a clap of your hands. Under the red bow is a not-so-small mechanical clasp that replaces the original on the strapless front-clasping undergarment. We hate to criticize, but [Randofo] really went off the deep end of hardware overkill on this project. The clasp itself is the electromagnetic coil removed from the case of a mechanical relay. An ATmega168 listens for a spike in sound pressure from a microphone, then drives the relay to release the feminine support system.

It is Valentine’s day. The question being is this romantic or sleazy? Watch the NSFW video after the break and let us know your opinion in the comments.

Macintosh Plus DJ Helmet With An IPad

January 14, 2011 by James Munns 39 Comments

Elaborate helmets are not a new concept, with many famous artists such as Daft Punk and Deadmau5 using them for stage shows. For a sculpture class, [Terrence] fashioned his own out of the body of a Macintosh Plus and an iPad conveniently sourced from eBay. After gutting the insides, the Mac Plus was fitted with parts from a helmet both for comfort as well as for keeping the whole setup head mounted. For additional eye candy, an LED visualizer was affixed below the iPad display. The rig is remotely controlled by a bluetooth keyboard, just for good measure. We think this setup easily stands up to other Daft Punk-esque style head mounts.

Be sure not to miss the video of the helmet featuring DJ Chameleon (a friend of [Terrence]) in action, as well as a number of other photos.

[Edit: Thanks to everyone who caught the Mac Plus/Pro error!]

Make The Wedding Ring Speak To Her

January 5, 2011 by Mike Szczys 41 Comments

It’s a nice touch to engrave a heartfelt message on a wedding band, and my couples choose to do so. But you can say a lot more with a 20 second audio message. That’s exactly what [Luke Jerram] did by etching an audio track into this ring. He uses his custom-built hardware to playback the message, which you can see in the video after the break. The ring is an Edison Cylinder, which works just like a modern record player except that the media is on a spinning drum (the ring) instead of a rotating disk. We wonder if this would sound a bit better with a high-end cylinder player.

While you’re on [Luke’s] page you might as well take a look at his image projecting ring as well. It has a color image slide on one side and a projection lens on the other. Wacky!

‘Tis The Season To Decorate Bags With EL Wire

December 24, 2010 by Mike Szczys 14 Comments

We hope you’ve already got parts on hand for your holiday projects because shipping might be a little slow at this time of year. But if you’ve got a bag and some unused EL wire here’s a one-day project you should try. Make yourself a Tron-inspired shoulder bag, or backpack.

On the right, [PT] is doing fantastic job of modeling with his electroluminescent offering. This is another Adafruit offering that holds your hand each step of the way from designing, to sewing, to wiring it up. This will go great with that glowing unitard he’s been working on.

[Alan Yates] has also done a spectacular job with his Tron backpack seen on the left. He picked up his EL wire on clearance at a place called “big-W” after Christmas last year. They were selling 3 meter segments (each with their own inverter) for just $3. We’re happy he got a deal and even more pleased that he found a use for it.

[Thanks Drone]
