We don’t want to call it a challenge because we fear the regulars at DEFCON can turn our piece of hardware into a smoking pile of slag, but we are planning to bring a bit of fun along with us. I’ll be wearing this classy headgear and I invite you to hack your way into the WiFi enabled Hackaday Hat.
I’ll be wearing the hat-of-many-scrolling-colors around all weekend for DEFCON 22, August 7-10th in Las Vegas. You may also find [Brian Benchoff] sporting the accessory at times. Either way, come up and say hello. We want to see any hardware you have to show us, and we’ll shower you with a bit of swag.
Don’t let it end there. Whip out your favorite pen-testing distro and hack into the hat’s access point. From there the router will serve up more information on how to hack into one of the shell accounts. Own an account and you can leave your alias for the scoreboard as well as push your own custom message to the hat’s 32×7 RGB LED marquee.
You can learn a bit more about the hat’s hardware on this project page. But as usual I’ve built this with a tight deadline and am still trying to populate all the details of the project.
[Agy] a fabric hacker in Singapore has made a chic light sensitive LED necklace, and written up the tutorial on her blog Green Issues by Agy. The lovely thing about this hack is that it doesn’t look like a breadboard round her neck, and most of the non-electronic components have been upcycled. [Agy] even used Swarovski crystals as LED diffusers for extra bling.
Using a LilyPad Arduino with a light sensor and a few LEDs, [Agy’s] circuit is not complicated. She seems to be just branching out in to wearable tech, so it is nice that she learnt to program different modes for bright and low light (see video below). Her background in sewing, refashioning and upcycling does show through in her crafty use of an old pair of jeans and lace scraps for this project.
We love tech focused jewelry like [TigerUp’s] LED matrix pendants or [Armilar’s] Nixie-ify Me Necklace, but they do scream Geek. DIY electronically enhanced accessories are becoming more commonplace with the variety of micro-controller platforms expanding rapidly. Low energy wearable boards like MetaWear are making it easy for the tech to be discreet and easily connected to your smartphone. 3D printing is enabling us to create durable enclosures, settings and diffusers like the ones used for LED Stegosaurus Spikes. With all these things, hobby wearable projects can not only be functional and durable, but can also look great too.
Do you think this necklace would look out of place in a non-geeky gathering? Have you got any helpful tips for [Agy’s] code? Have you tried using gems or crystals as diffusers and what were the results? Let us know in the comments below.

[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.

[Cynthia] has shared a great video of machine sewing parallel lines of conductive thread onto ribbon using a cording foot which usually comes standard with most machines. This technique could be particularly useful when using addressable LEDs like a NeoPixel to get the ground, data, and positive lined up fairly accurately. Sewing the conductive thread onto ribbon also makes it a hell of a lot easier to attach to many garments or textiles, and also makes it easier to replace or reuse.
The method is pretty easy, essentially using the grooves in the cording foot to guide the conductive treads and ensuring even spacing. Two of the lines are sewn down approximately 3 mm apart using a zigzag stitch. The third line is sewn separately making sure the stitching doesn’t break the first two lines. In the video, a striped ribbon is used which has slight troughs that additionally helps the threads stay in place and the sewer to stay on target.
[Cynthia] of Cynthia Designs Studio has been experimenting with embedding electronics in textiles and has quite a few great videos that you can check out on the Cynthia Designs Studio YouTube channel.
We have seen a machine embroidered LED matrix and a hand sewn LED quilt here on Hackaday, but those who have tried know that conductive thread can be very tricky to work with and keep conductivity. Do you have any tips or tricks for hand or machine sewing conductive thread? If so, please share in the comments below.

This little ring packs the guts of an NFC keyfob, allowing [Joe] to unlock his phone with a touch of his finger.
The NFC Ring was inspired by a Kickstarter project for a similar device. [Joe] backed that project, but then decided to build his own version. He took apart an NFC keyfob and desoldered the coil used for communication and power. Next, he wrapped a new coil around a tube that was matched to his ring size. With this assembly completed, epoxy was used to cast the ring shape.
After cutting the ring to size, and quite a bit of polishing, [Joe] ended up with a geeky piece of jewelry that’s actually functional. To take care of NFC unlocking, he installed NFC LockScreenOff. It uses Xposed, so a rooted Android device is required.
We’ll have to wait to see how [Joe]’s homemade solution compares to his Kickstarter ring. Until then, you can watch a quick video of unlocking a phone with the ring after the break.

The [RADLab team] has created an eye-opening RFID jacket for Make Fashion 2014. For this project, [Dan Damron, Chris Zaal, and Ben Reed] of RADLab teamed up with designer [Laura Dempsey] to create a jacket which responded both to a dancer on the runway and the audience itself. RADLab stands for Radio Frequency Identification Application Development Lab, so you can probably guess that RFID was their weapon of choice for interaction. We’ve got a bit of RFID experience here at Hackaday, having recently used it at The Gathering in LA. The [RADLab team] didn’t skimp on processing power for this jacket. A BeagleBone Black running Debian controls the show. The BeagleBone receives data from a Thingmagic M6e 4 port UHF RFID Reader. The M6e is connected to 4 directional antennas. The BeagleBone responds differently depending on which RFID card is read, and which antenna reads it. With the data processed, the BeagleBone then issues commands to a teensy 3.0, which controls WS2811 “Neopixel” addressable RGB LEDs sewn into the jacket.
During the fashion show, the jacket wearer danced with a second model who had RFID tags sewn into his t-shirt. The LED clusters on the front, back and sleeves of the jacket would light up, and change color and flash frequency based upon which tag and antenna got a read. Once the performance was over, the audience was encouraged to pick up tags and interact with the jacket themselves. The software was still very much beta, so the [RADLab team] monitored everything via WiFi and restarted the software when necessary.

Wearables are all the rage lately. Have you been eyeing the Pebble or one of the new smart watches lately but are not sure if it’s for you? With [GodsTale’s] “Retro Watch” you can now build your own, allowing you to try out a smart watch without making a huge investment.
This smart watch uses very common and easy to obtain parts: Arduino Pro Mini, HC-06 Bluetooth module, Adafruit’s 0.96’’ OLED display, and a lithium battery. It is amazing how few parts can be used to make such a functional project. While the example packaging shown is a bit rugged around the edges, it gets the job done. Having such simple hardware allows [GodsTale] to focus on the software. One of the coolest aspects of this project is the Android app [GodsTale] provides. The app provides basic functionality, such as viewing RSS feeds and Android notifications. Check out the GitHub and a more detailed write-up for more information.
It would be great to see this project evolve in the future, it has so much potential. We would love to see a custom circuit board, or a model for a 3D printed case for this awesome smart watch. See a video of the Retro Watch in action after the break. If you thought this was cool, check out a few of these recent hacks.
