[Furze] Sets Fire To Everything With Pyro Gloves

Pyro Build

Crazyman [Colin Furze] is back, and this time he’s setting everything on fire with his Pyro gloves. Though Hackaday readers are already a discerning bunch, this is a build we get submissions for all the time and feature fairly often. It would take an exceedingly impressive build to outshine the other fire hazards. But, as with his pneumatic Wolverine claws and his electromagnetic boots, [Furze] knows how to build the insane and then put on a good show.

The Pyro build is part of [Furze’s] 3-part celebratory X-Men extravaganza, a nod to the realm of superheroes coinciding with the release of the new X-Men film. [Furze] began with a custom reservoir cylinder that fitted with two solenoid valves: one for a pilot light and another for the big blasts. He’s also affixed a Piezo element and a AA battery, which sits in a cozy little container. The bulkier bits of the assembly sit in a backpack, hooking up, as expected, to the wrist-mounted devices. This flame cannon, however, is unique among the ones we’ve encountered here.

Interactive Gloves Turn Gestures Into Music

Imogen Heap wearing her Mi.Mu gloves

[Imogen Heap] is a UK-based musician who is trying to change the way we think about making music. She’s been working on a pair of gloves called the Mi.Mu, and they’re getting close to production.

In the included interview she explains that while computers and technology have brought many new advances to music, twiddling dials and pushing random buttons “is not very exciting for me, or the audience”. With these gloves, the artist becomes one with the music and interaction.

The current iteration of gloves use flex sensors along each finger to determine the movement (along with motion sensors for other gestures). She’s been through many designs and hopes to integrate e-materials into the next — using the actual glove as the sensor (not physical flex sensors).

She’s been working with both developers and musicians mapping the various motions of the gloves to music which makes sense in an intuitive way, and it’s very unique to see in action.

Commodore 64 Power Glove Is So Bad

November 14, 2013 by 11 Comments

The Nintendo Power Glove was terrible. Really, really terrible. Thanks to modern components, though, it’s possible to recreate the Power Glove experience in a way that doesn’t suck so much. That’s what [Leif] did with his motion sensing glove for the Commodore 64.

Instead of rolling his own IMU and putting it in a glove, [Leif] is using SonicWear SoMo, a glove originally designed to generate MIDI data for performance pieces. Inside this glove is a 9 DOF gyro/accelerometer/magnetometer, uC, battery, and XBee that can be easily reprogrammed to do something a little more (or less) useful than simply sending MIDI notes and commands.

[Leif] reprogrammed the XBees to use I/O line passing instead of sending serial data, and connected the recieving XBee to the C64 joystick port through a very simple circuit with a hex inverter.

All the code to turn a SonicWear glove into a C64 controller is available on the Github, and there’s a neat demo video of [Leif] demoing his glove at the VCF Midwest late last month.

Sensor Gloves From Joystick Pots

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.

Make Your Own Fume-extracting Glove Box

Here’s an easy to follow guide for building your own glove box. It’s a lab tool that contains the project you’re working on to keep things in or out. For instance, we could have used this a few years back when we tried to add an acrylic window to a hard drive. Instead, we ended up putting several hours of work into a cool-looking paperweight. But it will also come in handy for chemistry experiments that generate harmful or dangerous byproducts.

The picture above tells most of the story, but [Jason Poel Smith] does include several good tips about the construction in his video. He uses weather stripping along the edges of the clear container to ensure a seal. The hose is used to provide negative pressure so that no fumes leak out. We figure adding a smaller hole on the opposite side with a charcoal filter will help air pass into the chamber to serve as a fume extractor.

We’ve already seen a similar setup for a reflow oven. Perhaps this is the perfect solution to protect yourself from 3D printing fumes. We’re sure you saw the headlines about 3D printing being as bad as smoking cigarettes.

Virtual Chess Uses Glove Controllers

December 11, 2012 by 5 Comments

chess-using-glove-controllers

Check out the game of chess going on above. It’s a virtual game where each player uses a glove as the controller. Or course the game board and pieces are missing from this image. They’re displayed on a computer monitor which both players can see.

The hardware rather simple, and we think it would be a great project to challenge your microcontroller skills. Each glove has an accelerometer attached to it, as well as a ring of copper foil on the pointer finger and thumb. One ATmega1284 monitors both gloves. The accelerometer data is used to move the mouse cursor on the screen, while the contacts are used to grip or release a playing piece. The game board and pieces are displayed using MATLAB with controller commands fed to it via a USB connection.

If you’re more into building a mechanized game check out this pair of telepresence chess boards.

Vibrating Gloves Help Bring Back Finger Sensation After Injury

July 22, 2012 by 6 Comments

This glove is something of a medical breakthrough. It’s used in conjunction with a musical keyboard to teach the wearer how to play simple songs. The thing is, instrumental proficiency isn’t the end goal. This is aimed at returning sensation to patients who have had a spinal cord injury. Many of the test subjects — all of which had the injuries more than a year before participating — experienced increased sensation in their hands and that is quite rare under these circumstances.

There’s not a ton of information available on the hardware itself, but this image lets us make a  pretty good guess. The glove is a typical fingerless cycling glove. There are two conductors worth of ribbon cable going to each digit. On the ring finger you can make out the bulging hardware which appears to be a vibrating cellphone motor. The white enclosure houses the microcontroller which receives wireless commands from a PC. When it is time for a finger to move, the appropriate motor vibrates. This is best explained in the clip after the break.

Apparently the combination of sensory feedback and the need to react to it provides the therapeutic impetus which achieves the promising results seen in the study.
