A dress is shown in three shapes: the original, a slightly-heated A-line version, and a close-fitting body con version.

4D Knit Dress Skirts Waste

Regular 2D sewing of anything is inherently wasteful. You can align the pattern pieces however you want, but there’s going to be wasted everything — thread, fabric, and interfacing — whether you get it right the first time or not. Never mind the fact that people tend to create a muslin (prototype) first using inexpensive fabric (like muslin) for the purposes of getting the fit right.

A few examples of the lines than can be created.

The MIT Self-Assembly Lab x Ministry of Supply have come up with a 4D garment construction technique that minimizes waste while being pretty darn cool at the same time. They’ve created a knit dress that combines several techniques and tools, including heat-activated yarns, computerized knitting, and 6-axis robotic activation. The result is a dress that can be permanently molded to fit the body however and wherever you want, using a heat gun mounted on a 6-axis robotic arm.

As far as we can tell, a finished dress does not come off of the machine in the short demo video after the break. It looks like it still has to be sewn together, which creates some potential for waste, but absolutely nothing like conventional methods.

This is probably the coolest dress we’ve seen since the one covered in LCD panels.

Elegant Evening Dress Sports Servo-Actuated Flowers

There’s been plenty of research into “smart fabrics”, and we’ve seen several projects involving items of clothing with electronics integrated inside. These typically include sensors and simple actuators like LEDS, but there’s no reason you can’t integrate moving electromechanical systems as well. [Rehana Al-Soltane] did just that: she made an elegant evening dress with flowers that open and close on command.

It took [Rehana] a bit of experimentation to figure out a floral design that opens and closes smoothly without crumpling the fabric or requiring excessive force to actuate. She finally settled on a plastic sheet sandwiched between two layers of fabric, with pieces of fishing line attached that pull the edges inward. The lines are guided through a tube down the back of the dress, where a servo pulls or releases them.

The mechanical flower can be operated by touch — [Rehana] made one of the other flowers conductive by embedding copper tape between its petals and connected it to the capacitive touch sensor interface of an Atmel microcontroller. The micro is sitting on a custom PCB that’s worn on the hip, with wires going to the servo at the back. You can see how the system operates in the video embedded below.

The dress is [Rehana]’s final project for the famous “How To Make (almost) Anything” course at MIT, and required a wide variety of skills: the cable guide was 3D printed, the flower petals were laser cut, the PCB was milled, and the end product was sewn together. [Rehana] has a knack for making electronics-infused clothes and accessories, including the flexible PCB crown that she’s wearing in the image above.

Be The Star Of The Evening With This Light Up Prom Dress

[Kellechu] went full parent beast mode by creating a prom dress for her daughter. This incredible build is a tour-de-force of DIY crafting, combining sewing, electronics, 3D printing and programming.

The dress skirt is made of tulle that allows for the LED strip underneath to diffuse through. The top bodice is made of fiber optic fabric sewn between the fabric form with the dangling fiber optic threads grouped into bundles. The dangling fiber optic bundles were then inserted and glued into “out caps” that forced the strands to sit next to a NeoPixel LED. A 20 NeoPixel “Dots Strand” strip was strung around the waist line, affixing 12 of the NeoPixels with an “out cap” to light up the fiber optic bodice. The remaining NeoPixels were outfitted with a diffuser cap and hung lower to light up the tulle skirt portion of the dress.

A wand was 3D printed and housed with an RFM69HCW Packet Radio M0 Feather, a NeoPixel LED color ring and a TCS34725 Flora color sensor powered by a 2.2 Ah 3.7 V LiPo battery. Another RFM69HCW Packet Radio M0 Feather was placed in the dress to be able to receive messages from the wand so that the sensed color could be transmitted and the LED strip could be updated with the sensed color. The dress portion was powered by a 10 Ah 3.7 V LiPo, with the battery and electronics fitting snugly into yoga bike shorts with side pockets.

[Kellechu]’s Instructable is full of details about the process and is worth checking out. For example, [Kellechu] goes into detail about the troubles and care taken when dealing with the different media, making sure to avoid ironing the fiber optics so as not to melt the lines and experimenting with different sewing needles to limit the amount of dead fibers as collateral damage from the sewing process.

Dresses with LEDs and other lights are a big hit, as can be seen from our feature on an LED wedding dress.

Anouk Wipprecht: Robotic Dresses And Human Interfaces

Anouk Wipprecht‘s hackerly interests are hard to summarize, so bear with us. She works primarily on technological dresses, making fashion with themes inspired by nature, but making it interactive. If that sounds a little bit vague, consider that she’s made over 40 pieces of clothing, from a spider dress that attacks when someone enters your personal space too quickly to a suit with plasma balls that lets her get hit by Arc Attack’s giant musical Tesla coils in style. She gave an inspiring talk at the 2017 Hackaday Superconference, embedded below, that you should really go watch.

Anouk has some neat insights about how the world of fashion and technology interact. Technology, and her series of spider dresses in particular, tends to evolve over related versions, while fashion tends to seek the brand-new and the now. Managing these two impulses can’t be easy.

For instance, her first spider was made with servos and laser-cut acrylic, in a construction that probably seems familiar to most Hackaday readers. But hard edges, brittle plastic, and screws that work themselves slowly loose are no match for human-borne designs. Her most recent version is stunningly beautiful, made of 3D printed nylon for flexibility, and really nails the “bones of a human-spider hybrid” aesthetic that she’s going for.

The multiple iterations of her drink-dispensing “cocktail dress” (get it?!) show the same progression. We appreciate the simple, press-button-get-drink version that she designed for a fancy restaurant in Ibiza, but we really love the idea of being a human ice-breaker at parties that another version brings to the mix: to get a drink, you have to play “truth or dare” with questions randomly chosen and displayed on a screen on the wearer’s arm.

Playfulness runs through nearly everything that Anouk creates. She starts out with a “what if?” and runs with it. But she’s not just playing around. She’s also a very dedicated documenter of her projects, because she believes in paying the inspiration forward to the next generation. And her latest project does something really brilliant: merging fashion, technology, and medical diagnostics.

It’s a stripped-down EEG that kids with ADHD can wear around in their daily lives that triggers a camera when their brains get stimulated in particular ways. Instead of a full EEG that requires a child to have 30 gel electrodes installed, and which can only be run in a medical lab, stripping down the system allows the child to go about their normal life. This approach may collect limited data in comparison to the full setup, but since it’s collected under less intimidating circumstances, the little data that it does collect may be more “real”. This project is currently in progress, so we’ll just have to wait and see what comes out. We’re excited.

There’s so much more going on in Anouk’s presentation, but don’t take our word for it. Go watch Anouk’s talk right now and you’ll find she inspires you to adds a little bit more of the human element into your projects. Be playful, awkward, or experimental. But above all, be awesome!

“Starry Night” Dress Shines On The Experience Of Multiple Builds

[Dave Hrynkiw] wrote up some practical and useful detail around embedding electronics into clothing. It centers around his daughter’s “Starry Night” high school graduation dress, which is the culmination of a lot of experimentation in finding the best way to do things. His daughter accented the dress with LEDs to produce a twinkling starfield effect, and a laser-cut RGB pendant to match.

While [Dave] is the president of Solarbotics and pitches some products in the process of writing it all up, the post is full of genuinely useful tips that were all learned though practical use and experimentation. Imagine how awesome it must be growing up a child of a “local technology-hacking company” founder — akin to growing up as Willy Wonka’s progeny.

What advice does [Dave] have for making electronics an awesome part of garments? For example, the fact that regular hookup wire isn’t very well suited to embedding into clothing due to the need for high flexibility. There is also the concept of sequestering electronics into a separate Technology Layer — a must for anything that will be used more than once. The idea is to “build your technology so it can be isolated from the fashion aspect as much as possible. It makes building and maintenance of both the fashion and technology aspects much simpler.”

Slapping some LEDs and a battery pack into clothing might do the trick if all you care about is some bling, but if you want something that actually highlights and complements clothing while also being able to stand up to repeated use, this is a great read. A simple lighting effect that complements a design isn’t difficult, and there’s no need to reinvent the wheel or make the same mistakes others have encountered. Video is embedded below.

Knappa Tutu: Some Dancing Required

Sometimes, you see a lamp shade and you’re just intoxicated enough to put it on your head like a hat and dance around on the table. Other times, you see the same lamp shade, and decide to wire it up with Neopixels, an accelerometer, and an Arduino and make a flowery, motion-activated light show when you wear it as a dress. Or at least that’s what we’ve heard.

[Cheng] gets full marks for the neo-IKEA name for the project and bonus points for clean execution and some nice animations to boot. The build is straightforward: build up the lamp so that it fits around your waist, zip-tie in the RGB LED strip, and connect up accelerometer and microcontroller. A tiny bit of coding later, and you’re off to the disco. It looks like a ridiculous amount of fun, and a sweet weekend build.

Building A Business Around Generative Design And Marvels Of 3D Printing

Generative design is a method of creating something by feeding seed data into an algorithm. It might be hard at first to figure out how someone would build a business around this, but that’s exactly what Nervous System has been doing with great success. The secret is not only in the algorithm, but in how they’re bringing it to life.
