Laser-Cut ArcSin Dress Is Wearable Math

Using sewing simulation, 3D modeling and laser-cutting [Nancy Yi Liang] makes custom dresses that fit like a glove. Her project documentation walks us through all the steps from the first sketch to the final garment.

After sketching the design on paper, the design process moves into the digital domain, where an accurate 3D model of the wearer is required. [Nancy] created hers with Make Human, a free software that creates to-size avatars of humans from tape-measured parameters. Using the professional garment modeling software MarvelousDesigner (which offers a 30 day trial version), she then created the actual layout. The software allows her to design the cutting patterns, and then also drapes the fabric around the human model in a 3D garment simulation to check the fit. The result are the cutting patterns and a 3D model of the garment.

RFID Jacket Flashes the Crowd at Make Fashion 2014

RFID-DRESS

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.

Electronic cufflinks for the discerning hacker

icufflinks

[Phillip Torrone] gave us a heads up about a project he and [Limor Fried] along with [Mike Doell] have just wrapped up. Their aptly-named “iCufflinks” softly pulsate with light the same way in which you see many Mac products do.

The cufflinks are made from machined aluminum and have the ubiquitous “power symbol” milled into the face. Inside the cufflinks, you will find a small circuit board and a battery, which powers the device for up to 24 hours. The team reverse-engineered the soft LED pulse found in Mac products in order to deliver the exact same visualization in their cufflinks.

Ignoring for a minute, the name and the inspiration for the product, we think they are pretty darn cool. There’s nothing like a set of softly glowing cufflinks to spark conversation at any social gathering.

Like anything else you’ll find on Adafruit.com, the cufflinks are completely open source, so you can feel free to tweak and remix the design any way you’d like.
