Two University of Washington students exercised their creativity in a maker space and created a pair of gloves that won them a $10,000 prize. Obviously, they weren’t just ordinary gloves. These gloves can sense American Sign Language (ASL) and convert it to speech.
The gloves sense hand motion and sends the data via Bluetooth to an external computer. Unlike other sign language translation systems, the gloves are convenient and portable. You can see a video of the gloves in action, below.

As MMA continues to grow in popularity, the competition is getting tougher. There’s always someone else out there who’s training harder and longer than you are. So how do you get the advantage over your competitors? More push-ups? Sit-ups? Eat more vegetables? What about installing custom 2 by 1 inch, 5 gram PCB’s armed with an ATmega32U4, a MPU-6050 6 axis accelerometer and an RN-41 Bluetooth module into each of your gloves? Now that’s what we’re talking about.
[Vincent] and [Jooyoung] of Cornell joined their classmates in turning out another cool piece of electrical engineering. Fight Coach records data from the fighter’s gloves so that it can not only be analyzed to improve performance, but also interact with the fighter in real-time. Though not quite as immersive as some fighter training techniques we’ve seen, Fight Coach might just give a fighter a slight edge in the ring.
Fight Coach offers 3 modes of training: Defense mode, Damage mode and Free-Training mode. As usual with Cornell projects, all code, schematics and a wealth of information on the project is just a click away. And stick around after the break for a video demonstration of Fight Coach.

Winter is coming. We’ve see those gloves in stores made specifically to work with your smartphone. [hardsoftlucid] isn’t buying it. He made his own version using… well, you just have to see it.
Here’s an eBookmark for a real book. What? Well, you know how an eReader does a great job of keeping your place between reading sessions? This is an electronic bookmark for paper books which uses LEDs to show you where you last left off reading. [via Adafruit]
[Thomas Brittain] wrote in to share his BLE Module and Pulse sensor updates. Both were featured in a recent Fail of the Week column and the latest iteration takes them from fail to functioning!
You may be able to get a free XMOS xCORE starter kit. The company is giving away 2500 of them. [Thanks Tony]
After learning about custom labels for microcontroller pinouts from [John Meachum] we’re happy to get one more helpful tip: a breadboard trench is a great place to hide axial decoupling capacitors.
A bit of cutting, solder, and configuring lets you turn a simple gamepad into a 4-controller interface for MAME.
Many of the Hackaday Staff are into Minecraft (between Let’s Play videos, running servers, and building computers in-game it’s a wonder we get anything done around here). We restrained ourselves by not making this video of a Restone circuit Blender animation on your desktop into a full front page feature. [via Reddit]
After working on the DARPA Virtual Robotics Challenge this summer, visions of a Heinlenesque robotic actuator filled [Hunter]’s head. His lab had access to something called a Cyberglove that used flexible pots in each of the fingers, but each of these gloves cost the lab $15,000 each.
With a little help from some joystick potentiometers, [Hunter] whipped up a decent approximation of a $15,000 device that measures how much a user’s fingers are bent. The pots are tied into an Arduino and read with analogRead(), while a small Python script interprets the data for whatever application [Hunter] can imagine.
There are a few drawbacks to [Hunter]’s design – it’s not wireless, unlike the $15,000 version, and they certainly don’t look as cool as the real thing. Then again, the DIY version only cost 0.2% as much as the real deal, so we’ll let any apparent problems slide for now.
[Jair2k4] ditched the Altoids tins and found a new voltage source for this latest rendition of his taser gloves. Regular readers will remember his first iteration which used wrist-mounted enclosures containing the flash circuitry from disposable cameras to shock the wits out of someone with the laying on of hands. This one is a complete rework but it follows the same concepts.
The new shock circuitry is from a bug zapper in the shape of a fly swatter. We’ve seen these handheld devices before and dismissed them as a gimmick, but [Jair2k4] got his hands on a couple of them and found out they can put out a spark of up to 2300 volts. He set to work by getting rid of the tennis-racket-style grid at the top of the handle. He soldered on some contacts which reach to the tip of his middle-finger and thumb on some rubberized work gloves. The original handle was kept as it’s a nice battery holder and works well strapped to his forearm.
Does it work? You bet – even singing his arm hair and leaving welts on his skin. See for yourself after the break. And yes, this goes on the list of hacks you should recreate!

In a project that you’re sure to read about in police blotter someday, [Jair2k4] built a pair of Taser gloves that will shock your victim with they laying-on of hands.
Not surprisingly, this project was spawned from a conversation at work about what tech would best suit a vigilante crime fighter. [Jair2k4] suggested taser gloves, which drew a laugh, but also stuck in his mind. His prototype takes advantage of the flash circuitry from a disposable camera to step up battery voltage all the way up to 300 volts.
The gloves he’s using are rubberized fishing gloves which help ensure that he doesn’t shock himself. Wire travels from the capacitor to conductors sewn into the fingers and thumb of the gloves He’s got video embedded on his post that shows the bright spark and loud zap of a discharge when the conductors get close to one another. Altoids tins lined with electrical tape house the hardware, with a momentary push button used to charge the devices.
Hopefully criminals will not mind waiting for you to charge your weapons before they attack. But then again, [Jack Buffington’s] own version of a taser glove had the same issue. That one used conductors on the knuckle side of the glove, and involved long wires tethering the glove to a belt pack. Locating that back as a bracelet is a nice improvement on the idea.
[Rachel’s] Bluetooth glove is proving that you don’t have to be missing fingers to talk to the hand. You can see in the video after the break that, like us, she wears fingerless gloves while typing to keep the cold from causing pain in her hands (it’s so cold in here it’s like we’re [Bob Cratchit]). So why not make those gloves multitaskers?
She cracked open a small Bluetooth headset to see if it would play nicely with her fuzzy purple gloves. A bit of wire and some shrink tubing allowed for the speaker and microphone to be moved a bit further from the circuit board. Once those components had been extended she pinned everything in place to make sure it fit the bill. The components were then sewn in place and a microswitch for answering calls was repositioned in the hollow of the wearer’s palm. Now you’re free to work the day away, with all of your incoming calls already at your fingertips.
