Here’s Pi In Your Eye – HUD Goggles

[John Ohno] has found what is perhaps the best possible use for steampunk goggles: framing a monocular display for a Raspberry Pi-based wearable computer. [John]‘s eventual goal for the computer is a zzstructure-based personal organizer and general notifier. We covered [John]‘s zzstructure emulator to our great delight in July 2011. Go ahead and check that out, because it’s awesome. We’ll wait here.

[John] has been interested in wearable computing for some time, but is unimpressed with Google Glass. He had read up on turning head-mounted displays into monocular devices and recognized a great opportunity when his friend gave him most of an Adafruit display. With some steampunk goggles he’d bought at an anime convention, he started on the path to becoming a Gargoyle. He encountered a few problems along the way, namely SD card fail, display output issues, and general keep-the-parts-together stuff, but came out smelling like a rose. [John] has ideas for future input additions such as simple infrared eye tracking, the addition of a chording keyboard, and implementing a motorized glove for haptic learning. 

Want to make your own wearable display but have an aversion to steampunk? Check out this homebrew solution with (mostly) 3-D printed frames. And it has servos!

Wearable Raspberry Pi turns you into the Borg

The Hoboken hackerspace, MakerBar, recently hosted a very special guest – [Rob Bishop] from the Raspberry Pi Foundation. Wanting to impress [Rob], [Zach] and a few others from MakerBar put together a wearable computer based on the Raspberry Pi in just a few hours.

Putting a Raspi, small Bluetooth keyboard and mouse combo, and a USB charger equipped with lithium-ion battery wasn’t that hard. The tricky part was finding a wearable display. Luckily, [Zach] had a pair of MyVu Crystal video glasses lying around and after a tricky bit of dissassembly, the folks at MakerBar had a completely wearable computer.

Apart from the RCA cable connecting the Raspi to the glasses, the project is completely wireless; with a small webcam also mounted to the display, the Pi in the Face could easily be a platform for figuring out what to do with Google Glass.

[Zach] said the entire setup could be reconstructed for about $100, a fair price for being turned in to [Locutus] of Borg

Emulating a marching band with wearable instruments

[Scott] is a design and technology master’s student who just came up with The Imaginary Marching Band – virtual band instruments you can wear on your hand.

Taking inspiration from Minority Report and the NES Power Glove, the system is able to emulate 6 instruments at this point – A trumpet, trombone, tuba, snare drum, bass drum, and cymbals. The glove itself reads data from a variety of sensors and passes that onto an Arduino Uno which sends serial data back to a computer. This data is then parsed by a Serial – MIDI converter, and can then be played back through a sampler, synthesizer or piped into your sequencer of choice. Happily, [Scott] will be designing custom PCBs for his gloves to cut down on space and weight, and he’ll also be making his project open-source eventually.

[Scott] has a kickstarter page for his project, and so far he’s been on track towards getting this project funded. Check out a demo after the break.

25C3: State of the art wearable computing


[Kai Kunze] from the Embedded Systems Lab at Passau came to 25C3 to talk about Cyborgs and Gargoyles: State of the Art in Wearable Computing. There have been a lot of homebrew wearable computing solutions, but [Kai] covered specifically projects that could see everyday use in the real world.
