Hacking magnets into your skin

May 13, 2012 By Leave a Comment

[Dave] loved his iPod nano so much that he implanted 4 magnets in his arm to hold it.

Ok, go ahead and shout “fanboy” at your screen and say something snide about apples products or lament the poor working conditions at foxconn. Got it out of your system? Cool.

Actually, if we had to guess, [Dave] really isn’t doing this all for his love of the device or the company. It is much more likely that he is just really into body modding and this was a convenient theme for a mod. We find the idea pretty interesting. We’ve seen implants before, but they are usually of the RFID type. Typically those are used for some kind of security or computer control.

Implanting a magnet, however, is interesting because it could almost give you a “sixth sense” You could detect what was magnetic, and how magnetic it was. If we were going to do something like this, we would probably go fully sub-dermal though to help avoid infection.

What other kind of implants could you realistically do with today’s technology to give yourself other senses?

Sign and speak glove

May 4, 2012 By Leave a Comment

This wire covered glove is capable of turning your hand gestures to speech, and it does so wirelessly. The wide range of sensors include nine flex sensors, four contact sensors, and an accelerometer. The flex sensors do most of the work, monitoring the alignment of the wearer’s finger joints. The contact sensors augment the flex sensor data, helping to differentiate between letters that have similar finger positions. The accelerometer is responsible for decoding movements that go along with the hand positions. They combine to detect all of the letters in the American Sign Language alphabet.

An ATmega644 monitors all of the sensors, and pushes data out through a wireless transmitter. MATLAB is responsible for collecting the data which is coming in over the wireless link. It saves it for later analysis using a Java program. Once the motions have been decoded into letters, they are assembled into sentences and fed into a text-to-speech program.

You’ve probably already guess that there’s a demo video after the break.

A blanket that detects its own orientation

April 24, 2012 By Leave a Comment

If you want to capture a 3D model of a physical object, you could use a Kinect, a couple of lasers, constructive light, or even a simple touch sensor mounted on a robotic arm. Those are all expensive devices, and somewhat unnecessary now that you can just throw a blanket over an object and get a 3D model instantaneously.

The project is called IM BLANKY and it’s supposed to reproduce 3D shapes by simply throwing it over an object. The petals in the flower motif are pieces of conductive fabric that serve as contacts for the electrified tassel in the center of each flower. When the blanket is thrown over an object, the tassel is pulled by gravity, makes contact with one of the six conductive petals and sends a tilt switch to a microcontroller.

While we’re not too sure about the resolution IM BLANKY will provide with only 20 tilt sensors, but we imagine this could be used for a few medical applications.

Badges? We don't need no stinking badges!

April 19, 2012 By Leave a Comment

In a an obvious marketing move akin to a drug dealer offering up free samples, Urban threads is offering free badge plans for hackerspaces that have robotic embroidery machines. We’ve seen this trend of badges coming up lately and we don’t know if it is the boy/girl scout in us, or the punk rocker that makes us pine for them. You may laugh, but look at that skull with the welding goggles on. If you don’t think that’s badass… then we disagree.

The idea of giving some away free isn’t new. You can download free photoshop brushes, free fonts, free circuits and all kinds of other free stuff from sites that sell better versions as well. We just couldn’t pass up the chance to point out that skull, and helping out hackerspaces is always good in our eyes. So, who has one of those embroidery machines?

Closing in on Nixie cuff links

April 4, 2012 By Leave a Comment

It’s not Nixie cuff links yet, but we’re seeing a lot of potential for a few very classy accoutrements with [thouton]’s Nixie tube necklace.

The build was inspired by this much clunkier necklace that found its way onto the MAKE blog. Unlike the previous necklace, [thouton] used a much smaller Mullard ZM1021 indicator bulb. Instead of the normal 0-9 digits in a Nixie, this tube displays only A V Ω + - % and ~, betraying its pedigree as part of the display from an ancient multimeter.

To power the bulb, [thouton] is using a single AA battery and a boost converter salvaged from a camera flash unit. All the circuitry is on a little piece of perfboard encased in a handsome aluminum tube. Power is delivered through two terminals with a bit of audio cable standing in as the chain of the necklace. We suppose this could be re-engineered to use a coin cell battery; although a coin cell doesn’t offer as many amp hours as a AA cell, [thouton] is confident the AA will last for a few days. A coin cell would be more than enough for a night on the town, though.

Electric poncho keeps you warm on the go

March 22, 2012 By Leave a Comment

electric-poncho

With the mild winter and spring we have had, it might seem strange to think about ways to keep yourself warm, but there’s no better time than the present to prepare for chilly weather down the line.

In his blog [Berto] was thinking about how to keep warm when things cool off again, and decided that a heated poncho would be great to have on hand. He found a dead simple way to craft his heated poncho, requiring little more than a bit of wiring, some thread and cloth, as well as a pair of scissors.

[Berto] picked up a 12V-powered electric blanked, then proceeded to cut a head-sized slit in the middle of it, avoiding the heating coils. He sewed a bit of cloth around the hole to ensure it didn’t end up ripping over time, then he wired the blanket up to a 12V battery he tucked away in his backpack.

The result is a variable-temp poncho that you can use to keep warm in a variety of situations. [Alan Parekh] from Hacked Gadgets says that he thinks the poncho would be awesome on a full-day snowmobiling trip, and we think he’s right!

Continue reading to see a short video where [Berto] explains how to put one of these heated ponchos together.
