Wearable flames with fur and LED strips

wearable-flames-with-fur-and-LED-strips

[Finchronicity] over on Hackaday Projects has made a pretty awesome furry LED Vest to keep him warm and well lit at this year’s Burning Man. He is using a Teensy 3.0 that drives strips of 470 WS2811 LEDs.

The vertically aligned strips run on a continuous sequence which reaches up to 31 frames per second using precompiled animations. The effects rendered in Processing or video mapped, are captured frame by frame and stored as raw color data to an SD card. Playback uses the NeoPixel library to control the strips. The high resolution LEDs, with the video mapped fire and the long pile fur, create one of the nicest flame effects we have seen on clothing.

We’ve also seen the Teensy 3.0 and WS2811 LEDs used as a popular combination for building huge displays, a 23ft tall pyramid, and more recently in the RFID jacket at Make Fashion 2014. Have you made or seen a great Teensy/WS2811 project you would like to share with us? If so, let us know the details in the comments below.

Forget Stopping Bullets – Vest Warms You While Stopping Taser

carbon-ribbon-clothing

[Bruce Wayne] [Shenzhen] wanted a garment that would protect him from a jolt, while keeping him toasty in the cold weather. Well that’s not it at all, these are merely two of his projects using the same material in different ways.

We’re going to start with the infrared image on the right. This is a vest with chest and back pieces made of carbon tape totaling two meters of the material swirled on each side. Hook it to a power source and the carbon tape warms the wearer. Portability is something of an issue as each “element” takes 36 W of power (3A at 12V). Click through for advice on how to interface the tape with the power source.

Onto the main event… avoiding electrical shock when you get all up in the grill of that mall cop you’re hated for years. [Shenzhen's] jacket is really just an ordinary long-sleeved coat. But he separated the lining at the bottom seam and used fusible material to hold the carbon tape in place. The carbon tape provides a better conductor than your skin, preventing the shock from stunning you as it was intended. This really is the thing of superheroes, or former editors who should have known better.

Light up biking vest shows impatient drivers how fast you are going

[Mykle Hansen] is an avid cyclist, and safety is a big concern for him. He says that bicyclists often receive a lot of honks and grief from passing motorists because they perceive them as moving far slower than they really are. According to [Mykle], this misjudgment can result in “right hook” collisions, which kill several bicyclists each year. To increase his nighttime visibility and to give drivers a better idea of how fast he’s traveling, he constructed a bicycling vest that displays his current speed in large 7-inch tall numbers.

He uses an off-the-shelf speedometer to get his current speed, feeding that data to an Arduino tucked inside his vest. The Arduino then lights the appropriate EL wire digits to relay his speed to motorists behind him.

It seems to work pretty well if the video below is any indication, and there’s no denying that it will catch a driver’s attention at night. If you’re thinking of making one for yourself, check out his Make:Projects page for a complete look at how it was put together.

DIY Heated vest/clothing


[Jared] sent in his experiment in building his own heated vest for motorcycle riding. He used some of the ever so common enamel coated wire and some surplus teflon tape in place of Teflon coated wire. So far he’s been testing things out with a bench power supply, but it seems to be working. Despite my love of building my own stuff, I’d probably just pony up for a commercial product. His site is hosted on his DSL, so I’ve put up a mirror here. (with some tweaks to the thumbnails to make them load faster.)
