IPhone Controlled Daft Punk Helmet Replica A Dazzling Build

October 5, 2011 by 21 Comments

This Daft Punk helmet replica is beautiful to look at, but the deeper we delve into the build process, the more we begin to think that the entire project is a piece of artwork. [Harrison Krix] has been working on it for months, and just posted his three-part build log in September. Check out the video and the links to all three parts after the break.

Now [Harrison] isn’t new to prop replica scene. He’s the guy responsible for the other fantastic Daft Punk helmet we saw last year. He’s tapped the same fabrication skills to churn out an equally impressive chromed helmet, complete with addressable flashing LEDs. He built his own mold to create the body of the helmet, reminding us of the Storm Trooper helmet replicas we saw in July. While this was off being coated in chrome, he got down to business with the electronics.

The visor of the helmet has a red LED marquee. This, along with the multicolored visor sides and ear pucks, is controlled by an Arduino yellow jacket. The lights can be controlled by an iPhone app that connects to the helmet via WiFi, letting a user push custom messages to the display, and alter the light patterns. The build shines on the inside as well as the outside with an incredibly clean LED matrix build, and clever control placement for switching each part on or off.

High Voltage Hacks: All About Electroluminescence

August 25, 2011 by 11 Comments

Although many might not know it, electroluminescent materials use high voltage, and thus qualify for our featured topic. Many may assume that these sheets work in the same way as LED lights, using low-voltage DC power.  This, however, is not the case, as they need around 100 volts of AC current to allow them to light up.

For a battery-powered solution, this means converting the battery’s DC power to AC. Adafruit has a good tutorial about working with EL wire and powering it up using a portable inverter. One should obviously be careful to properly insulate any clothing using this material as being shocked is generally not fun.

The video after the break is pretty long, but is well produced and will give you a good background of EL use. If you don’t have 30 minutes to dedicate to this, be sure to at least skip to 2:43 to see one of the coolest EL shirts we’ve seen.

Bluetooth Wristwatch Based On An Arduino

August 23, 2011 by 30 Comments

We hate to admit it, but we missed out on the TI Chronos watch deal last week. While we’re still a little bit burned over the fact that these watches sold out so fast, [Ahmet] sent in his Open Source Bluetooth Watch and we’re thinking this could eventually be a decent replacement.

The watch is built around an Arduino Pro Mini, a scavenged Nokia LCD, and a BlueSMiRF Gold. The Bluetooth connects to a Nokia N900 with a little Bluetooth client app [Ahmet] wrote. He also wrote a small GUI for the watch’s LCD display. Afterwards, he was able to display missed calls, new email, and is now working on support for changing songs on his N900’s media player.

Admittedly, a little work needs to be done on the enclosure. Still, the potential for this watch is much greater than the iPod as a watch project we saw last year. Right now, we’re thinking about what could be added to [Ahmet]’s watch. An accelerometer would probably be on the top of our list, but if you have any ideas feel free to leave them in the comments.

Check out the walk through of the watch’s functions after the break.

The Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Asstance Device.. Or The Tacit

August 19, 2011 by 14 Comments

Here is a hack that takes the stick out of the blind mans hand. [Steve] has been working on the Tacit, a wrist mounted sonar device with haptic feedback, it’s like strapping a bat to your wrist to help you see. The Tacit uses two sonar ping sensors to measure the distance to the nearest obstacle, the relative distance to an object is then fed back to the user using two servos which apply pressure to the back of the wrist. The Tacit is sporting an Arduino pro mini to control the ping sensors and drive the servos, and runs off a 9 volt battery.

This is not an entirely new concept, haptic headbands have been around on the net for a while, but the Tacit allows the user to detect  obstacles on the ground waiting to trip you up. All in all a neat hack that may have a future in helping the blind. Check out the video after the break to see it in action.

Lighted Shoe Ruffles — He’ll Never Step On Your Toes Again

August 9, 2011 by 11 Comments

Whether for fashion, emergency lighting, or just to make a statement, these lighted shoe clips make for a unique footwear accessory. [Becky Stern], who we’ve seen before hacking automatic knitting machines, tackles this quick lighted project.

The electronics are simple, two LEDs connected in parallel to a button battery by some conductive thread. The circuit is the same as an LED throwie, but she’s using a sewable battery holder. The ruffle is made by cutting out and folding several circles of fabric. We’re not too used to working with this building material and were glad to hear her tip on fusing the cut edges with a lighter. She’s also got a good tip about bending one LED lead in a square shape and the other in a round shape to keep track of the polarity. After sewing everything together and completing the circuit with the conductive thread [Becky] adds a paper clamp making this easy to use with any shoe. In fact, the guy’s don’t have to miss out on the fun as this could easily double as a boutineer.

Don’t miss [Becky’s] complete walk through video embedded after the break.

Wearable Video Coat

July 12, 2011 by 13 Comments

[David Forbes] is no stranger to the weird and esoteric, so he created a color LED TV built into a lab coat. He plans on bringing it to Burning Man next month.

The RGB LEDs are mounted narrow flex boards, providing a 160×120 pixel NTSC display. Video processing is taken care of by an Xilinx FPGA that takes the YCrCb video feed from a video iPod and converts it into four separate RGB streams for the front, back, and the two sides. The requisite controls for brightness and color are on the shoulders.

Of course, the build wouldn’t be over-the-top without the ability to plug a Nintendo into a lab coat, so there’s an NTSC input on an RCA jack. Everything is powered by two 11.1 V, 5Ah radio-control LiPo battery packs that should power this for a while.

Check out a video of the LED lab coat below.

VU Meter Scarf Lights Up The Night

July 8, 2011 by 10 Comments

vu_meter_scarf

[Eli Skipp] wrote in to share a project she has been working on bit by bit, for over a year – an LED VU meter scarf. The project was originally going to be built using a custom PCB, but no matter how long she spent troubleshooting the piece, it just wouldn’t work right. She eventually broke down and purchased a VU meter kit, which worked out quite a bit better than the homebrew version.

The VU meter circuitry is tucked away inside the scarf as she shows in the video below. The LEDs are connected using conductive thread sourced from Lamé Lifesaver, which she says is far more durable than other threads she has tried. After originally testing the VU meter, she was unimpressed by the output of the LEDs, so she swapped them out for brighter ones, which look much better. It looks like it works quite well – we definitely dig the idea of a scarf with a built-in VU meter, even if it was partially built from a kit.

Continue reading to see [Eli] give a quick demonstration and a rundown of the scarf’s construction.
