Electromagnetic Field: A Cyberpunk Headdress To Be Noticed In

Posted on by

At the recent Electromagnetic Field hacker camp in the UK, one of the highlights was the Null Sector, a cyberpunk-themed zone best described as something close to the set of Blade Runner made from shipping containers, clever props, and lighting. Our community rose to the occasion with some truly impressive costumes and wearable electronics, lending the venue a real authenticity.

Among the many creations on show there was one that stood quite literally head and shoulders above the rest. [Chebe]’s colour stealing sound reactive LED headdress is a confection of Neopixels, organza, and transparent floor protectors on a wire frame, …read more

Robots Invade Your Personal Space

Posted on by

If you have ever had to complete a task such as building a LEGO model over a remote connection, you will know that the challenges are like an absurd grade school group project. The person giving directions often has trouble describing what they are thinking, and the person doing the work has trouble interpreting what the instructor wants. “Turn the blue block over. No, only half way. Go back. Now turn it. No, the other way. NO! Not clockwise, downward. That’s Upward! Geez. Are you even listening‽” Good times.

While you may not be in this situation every day, the …read more

MIT Makes Washable LED Fabric

Posted on by

Let’s face it, one of the challenges of wearable electronics is that people are filthy. Anything you wear is going to get dirty. If it touches you, it is going to get sweat and oil and who knows what else? And on the other side it’s going to get spills and dirt and all sorts of things we don’t want to think about on it. For regular clothes, that’s not a problem, you just pop them in the washer, but you can’t say the same for wearable electronics. Now researchers at MIT have embedded diodes like LEDs and photodetectors, into …read more

Sonar in Your Hand

Posted on by

Sonar measures distance by emitting a sound and clocking how long it takes the sound to travel. This works in any medium capable of transmitting sound such as water, air, or in the case of FingerPing, flesh and bone. FingerPing is a project at Georgia Tech headed by [Cheng Zhang] which measures hand position by sending soundwaves through the thumb and measuring the time on four different receivers. These readings tell which bones the sound travels through and allow the device to figure out where the thumb is touching. Hand positions like this include American Sign Language one through ten. …read more

RCA TV Gets New Life As Interactive Atltvhead

Posted on by

TVs are usually something you sit and passively watch. Not so for [Nate Damen’s] interactive, wearable TV head project, aka Atltvhead. If you’re walking around Atlanta, Georgia and you see him walking around with a TV where his head should be, introduce yourself! Or sign into Twitch chat and take control of what’s being displayed on the LEDs which he’s attached to the screen. Besides being wearable technology, it’s also meant to be an interactive art piece.

For this, his third version, the TV is a 1960’s RCA Victor Portable Television. You can see some of the TVs he found …read more

Is That a Tweet on Your Belt Buckle or Are You Just Happy to See Me?

Posted on by

What a time to be alive! The range of things you never knew you needed but absolutely must have expands at a breakneck pace, such that it’s now possible to pick up a belt buckle with an embedded LED matrix to scroll messages. We have no idea what the use case for something like this is, but some people will buy anything.

One such person was a friend of [Brian Moreau], who doubled down after being gifted the glowing bauble by turning it into a WiFi enabled Tweet-scrolling belt buckle. It appears to be a just for fun project, and …read more

Hacked Fitness Trackers Aim to Improve Mental and Physical Health

Posted on by

We all know that the mind can affect the body in dramatic ways, but we tend to associate this with things like the placebo effect or psychosomatic illnesses. But subtle clues to the mind-body relationship can be gleaned from the way the body moves, and these hacked fitness monitors can be used to tease data from the background noise of everyday movements to help treat mental health issues.

Over the last few years, [Curt Smith] of the Child Mind Institute has been able to leverage an incredibly cheap but feature-packed platform, the X9 Pro Sports Bracelet, a fitness band that …read more

Be the Electronic Chameleon

Posted on by

If you want to work with wearables, you have to pay a little more attention to color. It is one thing to have a 3D printer board colored green or purple with lots of different color components onboard. But if it is something people will wear, they are going to be more choosy. [Sdekon] shows us his technique of using Leuco dye to create items that change color electrically. Well, technically, the dye is heat-sensitive, but it is easy to convert electricity to heat. You can see the final result in the video, below.

The electronics here isn’t a big …read more

Color Organ Dress, A Wearable With Audio Feedback

Posted on by

There is a huge amount of interest among our community in wearable electronics, but it is fair to say that it is a technology that has a way to go at our level in terms of its application. Some twinkly LEDs are all very well, but unless you have the arrived-on-a-spaceship-from-the-future aesthetic of someone like [Naomi Wu] to carry them off they get old rather quickly.

What the sew-on LED sector of wearable electronics is waiting for are some applications, wearable lights that do something rather than just look pretty. And [Moko] has a project that takes them in that …read more

34C3: Fitbit Sniffing and Firmware Hacking

Posted on by

If you walked into a gym and asked to sniff exercise equipment you would get some mighty strange looks. If you tell hackers you’ve sniffed a Fitbit, you might be asked to give a presentation. [Jiska] and [DanielAW] were not only able to sniff Bluetooth data from a run-of-the-mill Fitbit fitness tracker, they were also able to connect to the hardware with data lines using test points etched right on the board. Their Fitbit sniffing talk at 34C3 can be seen after the break. We appreciate their warning that opening a Fitbit will undoubtedly void your warranty since Fitbits don’t …read more
