[Rob] has been hard at work designing and building this LED suit which he can wear to parties. He’s got it working, although right now it’s just a pair of pants. It reacts to sound, and has the potential to be controlled from a smartphone via Bluetooth. You’ll find a video description of the build embedded after the break.
The planning started off by selecting driver hardware for the LEDs. [Rob] wanted the suit to pulse to the music in the room so he grabbed an MSGEQ7 chip. When connected to a microphone and opamp this chip will output a signal which can be used as a VU meter. He built the hardware into an Arduino shield, then got to work on the LED driver board. He’s using LED strips, but they’re not individually addressable. Instead he cut loops which wrap around the wearer’s legs. Each loop connects the pins of a TLC5947 LED driver chip which sinks a constant current and offers PWM abilities. He’s using PNP transistors on the high side.
For anyone that’s ever worked in a Tyvek suit before you’ll know they don’t breathe. Sweat will literally be pouring off of you. And we’d bet that’s what cause the short that burned the back of [Rob's] leg at a recent party. Then again, your light-up pimp coats are going to be hot to wear too.

Guess where this guy’s headed in his suit of many colors? If you said Burning Man give your self a pat on the back. After making a half-hearted EL suit for the festival in 2010 [Sander] decided he needed to step it up this year. He bought and affixed 200 LED modules to this suit so that he could light up the night.
They’re mounted in a grid, and in order to keep the changing patterns orderly he mapped the physical location of each in his code using a two-dimensional array. The controller uses an Arduino nano to push the patterns out to the array via SPI.
[Sander] included several different visual effects for the controller. One strobes the suit starting from the right cuff when he shakes someone’s hand. There’s also an audio spectrum analyzer chip and microphone that let him pulse the lights to music. You can see how bright this thing is in the image above, but to get the full effect shouldn’t skip the video after the break.
He’s entered the project into the Full Spectrum Laser Cutter giveaway. If he wins, we expect laser cut goodness for next year’s festival!

What would you do if you were a foot or two taller? How about if you had an arm span two times as wide as you have now?
A group of Japanese engineering students asked themselves the same question and built a wearable chassis that does just that. Their project is called “Sukerutonikusu”, which we believe roughly translates to: “This is freaking awesome, we’ll take two!”. [Thopter] however informs us that it translates to “Skeletonics”, a fusion of the words “skeleton” and “mechanics”.
The suit is comprised of lightweight aluminum pipes and sheeting, allowing for it to be powered solely by the person wearing it. Stepping inside the chassis looks like it lifts the wearer about a foot and a half off the ground, while increasing their wingspan by nearly 6 feet! In the video embedded below you can see that while in the suit, the wearer is quite agile, and even has the ability to run at a decent tick.
If this ever comes to market, you can bet we will buy one in a heartbeat – until then, we will have to settle for making RoboCop sounds as we walk about the office.

When the tipline popped up with this LED suit, part two, by [Marc DeVidts] we were expecing a simple led version of the previously known EL coat.
Well we were right and wrong in the same instance. Correct in that like predictions, the outcome is stonking great. Wrong in that this suit far outpaces EL in abilities we weren’t expecting. Namely to start off, an iPhone app over WiFi dictates to some 200 Arduino multiplexed RGB LED modules to dance randomly or follow patterns; an accelerometer and microphone are also implanted to further some effects. And finally if the suit isn’t enough to make you giddy, his PCB and enclosure milling surely will. Catch a video of the entire setup after the break.
