Have you ever come across an Internet meme and just thought to yourself, “I have to bring this into the physical world!” Well [0xb3nn] and [Knit Knit] did. They decided to take the classic nyan cat meme and bring it to life.
The frame is 24″ x 36″. Many hours went into the knitting process, but the result obviously turned out very well. The stars include 24 LED sequins to add a sparkling animation effect. These were sewn onto the back of the work using conductive thread. They are bright enough to shine through to the front where needed. These connect back to an Arduino Pro Mini 5V board.
The Arduino is also connected to a capacitive touch sensor. This allows the user to simply place their hand over the nyan cat image to start the animation. No need for physical buttons or switches to take away from the visual design. An Adafruit AudioFX sound board was used to play back a saved nyan cat theme song over a couple of speakers. The source code for this project is available on github. Be sure to watch the demo video below. Continue reading “Embroidered Nyan Cat Brings a Meme to the Real World”
[Andrew] is bringing his old mechanical sewing machine into the 21st century by adding an Arduino control module. Originally, his Alfa sewing machine could only do a straight stitch or a zig-zag of varying widths. Since this was an old sewing machine, all of the controls were knobs and levers. RC car servos were installed in the sewing machine and now are solely responsible for controlling, in real time, the horizontal movement of the needle and the amount of stroke of the feed dogs (the metal components responsible for advancing the fabric through the sewing machine). There is also a switch on the needle bar that feeds back to the Arduino when the needle is in the full-up position.
With full control of the stitch width and fabric advance, it is possible to come up with some awesome stitch patterns that were not possible on this machine before. Each of the stitch patterns are pre-programmed in the Arduino. Right now it is possible to control the sewing machine over the Arduino’s serial USB connection but the workflow for such an operation is in its infancy. [Andrew] plans on making this sewing machine fully automatic so that he can embroider letters and numbers.
Although the project is still a work in progress, [Andrew] has made his preliminary Arduino code available for folks who want to further his accomplishments. To continue reading about hacked sewing machines, check out this one converted to an embroidering machine.

If you were in the market for a sewing machine with embroidery capabilities, you’d either be spending a bunch of money or settling for a lower-cost machine that can only do a handful of pre-programmed designs. A DIYer by the name of [SausagePaws] came up with a 3rd option, he would build one himself. He was also highly motivated, [Mrs SausagePaws] wanted one!
An off the shelf embroidery machine is similar to a standard sewing machine except the movement of the fabric is done automatically rather than by hand. Not only does the work move, but it has to move in time with the needle traveling up and down. [SausagePaws] took a no-nonsense approach and decided the simplest way to go about the task was to mount an embroidery hoop to the end of an XY drive system.

Want a nifty way to combine the craft of embroidery with electronics? The folks working on the open source Embroidermodder demoed their software by generating an embroidery of the KDE logo using a TFT screen and an Arduino.
Embroidermodder is an open source tool for generating embroidery patterns. It generates a pattern and a preview rendering of what the embroidery will look like when complete. It’s a cross-platform desktop application with a GUI, but the libembroidery library does the hard work in the background. This library was ported to Arduino to pull off the hack.
While generating pictures of embroidery with an Arduino might look neat, it isn’t too useful. However, since the library has been ported it is possible to use it to control other hardware. With the right hardware, this could be the beginning of an open source embroidery machine.
After the break, check out a video of the pattern being generated.

[Wei Chieh Shih] really moves the needle when it comes to wearable technology. His textile design project entitled I Am Very Happy I Hope You Are Too is a striking marriage of masterful hand embroidery, delicate circuitry, and careful programming.
[Wei] is using an Arduino micro to drive a matrix of surface-mount LEDs in the Hello, World video, which is a ramp-up to the scrolling text version that’s
in progress now finished. That full version is part of his residency project at Arquetopia in Oaxaca, Mexico and displays snippets of emails from his past relationships. It’s huge, with multiple matrices as large as 8×25 pixels!
No build notes could be found for this or any of [Wei]’s similar projects, like this awesomely dangerous 200 laser diode jacket or this eerily beautiful light installation on Taiwan’s north beach. Based on the pictures, our speculation is that he is using ordinary 6-strand embroidery floss to make stem or half cross-stitches on all the paths. He then runs very thin, flexible conductor underneath the channel of stitches and solders the wires to the component pads.
If [Wei] wants another way to wear his heart on his sleeve, he could investigate these dynamic LED clothing hacks.
Update: [Wei] has completed this project, and has more information available at his Behance site.
