Teleknitting, the brainchild of Moscow artist [vtol], is an interesting project. On one hand, it doesn’t knit anything that is useful in a traditional sense, but on the other, it attempts the complex task of deconstructing broadcasted media into a simpler form of information transmission.
Teleknitting’s three main components are the processing and display block — made up of the antenna, Android tablet, and speaker — the dyeing machine with its ink, sponges, actuators, and Arduino Uno, and the rotating platform for the sacrificial object. A program running on the tablet analyzes the received signal and — as displayed on its screen — gradually halves the number of pixels in the image until there is only one left with a basic representation of the picture’s colour. From there, thread passes over five sponges which dye it the appropriate colour, with an armature that responds to the broadcast’s volume directing where the thread will bind the object.

Our Norwegian is pretty weak, so we struggled a little bit with the documentation for a big public LED art project in the lighthouse (translated) in Horten, Norway. But we do speak the universal language of blinkies, and this project has got them: 3,008 WS2812b LEDs ring the windows at the top of the lighthouse and create reactive patterns depending on the wave height and proximity of the ferry that docks there.
This seems to be an evolving project, with more features being added slowly over time. We love the idea of searching for the WiFi access point on the ferry to tell when it’s coming in to port, and the wave height sensor should also prove interesting data, with trends at the low-frequency tidal rate as well as higher frequency single waves that come in every few seconds. What other inputs are available? How many are too many?
It’s so cool that a group of tech-minded art hackers could get access to a big building like this. Great job, [Jan] and [Rasmus] and [everyone else]!

If you take an object and turn it into something else, does that constitute a hack? Can a musical robot call to question the ethics of firearms exports? If you take a disabled shotgun and turn it into a flute, does it become an art piece? Deep questions indeed — and deliberately posed by [Constantine Zlatev] along with his collaborators [Kostadin Ilov] and [Velina Ruseva].
The Last Gun — a mechano-robotic flute, as [Zlatev] calls it — is built from recovered industrial parts, played using compressed air, and controlled by an Arduino and Raspberry Pi. After graphing the annual arms exports from the United States, the installation plays a mournful tune for each year that they rise, and a jubilant theme for each year they fall.

Kate Reed has a vision for elevating the less talked about parts of ourselves, and of society. Through her art, she wants people to think about a part of themselves that makes them feel invisible, and to anonymously share that with the community around them. The mechanism for this is Invisible, a campaign to place translucent sculptures in public places around the world. The approach that she has taken to the project is very interesting — she’s giving the art away to empower the campaign. Check out her talk from the Hackaday SuperConference.

Over the last decade or so, the cost to produce a handful of custom PCBs has dropped through the floor. Now, you don’t have to use software tied to one fab house – all you have to do is drop an Eagle or KiCad file onto an order form and hit ‘submit’.
With this new found ability, hackers and PCB designers have started to build beautiful boards. A sheet of FR4 is no longer just a medium to populate parts, it’s a canvas to cover in soldermask and silkscreen.
Over the last year, Star Simpson has been working on a project to make electronic art a reality. Her Circuit Classics take the original art from Forrest Mims’ Getting Started In Electronics notebooks and turn them into functional PCBs. It’s a kit, an educational toy, and a work of art on fiberglass, all in one.
At the 2016 Hackaday Superconference, Star gave her tips and tricks for producing beautiful PCBs. There’s a lot going on here, from variable thickness soldermasks, vector art on a silkscreen, and even multicolored boards that look more at home in an art gallery than an electronics workbench.

We were just starting to wonder exactly what we’re going to do with our old collection of cassette tapes, and then along comes art robotics to the rescue!
Russian tech artist [::vtol::] came up with another unique device to make us smile. This time, it’s a small remote-controlled, two-wheeled robot. It could almost be a line follower, but instead of detecting the cassette tapes that criss-cross over the floor, it plays whatever it passes by, using two spring-mounted tape heads. Check it out in action in the video below.
Some of the tapes are audiobooks by sci-fi author [Stanislaw Lem] (whom we recommend!), while others are just found tapes. Want to find out what’s on them? Just drive.

Sometimes Hackaday runs in closed-loop mode: one hacker makes something, we post it, another hacker sees it and makes something else, and we post it, spiraling upward to cooler and cooler hacks. This is one of those times.
One of our favorite junk-sound-artists and musical magicians, [Gijs Gieskes], made this magnetic-levitation, rubber-band, percussive zither thing after seeing our coverage of another magnetic levitation trick. Both of them simply have a Hall sensor controlling a coil, which suspends a magnet in mid-air. It’s a dead-simple circuit that we’ll probably try out as soon as we stop typing.
But [Gijs] took the idea and ran with it. What looks like a paperclip dangles off the magnets, and flails wildly around with its tiny steel arms. These hit a zither made of rubber bands with a bamboo skewer as a bridge, pressing down on a piezo. The rest is cardboard, copper-clad, and some ingenuity. Watch it work in the video embedded below.
