Circuit Sculpture Hack Chat

November 4, 2019 by 7 Comments

Join us on Wednesday, November 6 at noon Pacific for the Circuit Sculpture Hack Chat with Mohit Bhoite!

For all the effort engineers put into electronic design, very few people ever get to appreciate it. All the hard work that goes into laying out a good PCB and carefully selecting just the right components is hidden the moment the board is slipped into an enclosure, only to be interacted with again through a user interface that gets all the credit for the look and feel of the product.

And yet there are some who design circuits purely as works of art. They may do something interesting or useful, but function is generally secondary to form for these circuit sculptors. Often consisting of skeletons of brass wire bent at precise angles to form intricate structures, circuit sculptures are the zen garden of electronic design: they’re where the designer turns to quiet the madness of making deadlines and meeting specs by focusing on the beauty of components themselves and putting them on display for all to enjoy.

By day, our host Mohit designs and builds hardware at Particle. By night, however, the wires and pliers come out, and he makes circuit sculptures that come alive. Check out his portfolio; you won’t be disappointed. This Hack Chat will be your chance to find out everything that goes into making these sculptures. Find out where Mohit gets his inspiration, learn his secrets for such precise, satisfyingly crisp wire-bending, and see what it takes to turn silicon into art.

Wire Bender Aims To Take Circuit Sculptures To The Next Level

July 1, 2019 by 28 Comments

It doesn’t seem as though bending wire would be much of a chore, but when you’re making art from your circuits, it can be everything. Just the right angle in just the right place can make the difference between a circuit sculpture that draws gasps and one that’s only “Meh.”

[Jiří Praus] creates circuit sculptures that are about as far away from the “Meh” end of the spectrum as possible. And to help him make them even more spectacular, he has started prototyping a wire-bending machine to add precision to his bends. There’s no build log at the moment, but the video below shows progress to date. All the parts are 3D-printed, with two NEMA 17 steppers taking care of both wire feed and moving the bending head. It appears that the head has multiple slots for tools of different shapes. For now, the wire is rotated around its long axis manually, but another stepper could be added to take care of that job.

[Jiří] tells us that while he loves making circuit sculptures like his amazing mechanical tulip, he hates repeating himself. He hopes this bender will make repeat jobs a little less tedious and a lot more precise, and we hope he goes forward with the build so we get to see both it and more of his wonderful works of circuit art.

Volkswagen EGon Is A Rolling Electric Car Circuit Sculpture

May 11, 2019 by 19 Comments

Over the past few decades of evolution, cars have grown to incorporate a mind-boggling number of electric components. From parking distance sensors, to the convenience of power locks and windows, to in-car entertainment systems rivaling home theaters. Normally this interconnected system’s complexity is hidden between exterior sheet metal and interior plastic trim, but a group of students of Volkswagen’s vocational training program decided to show off their internal beauty by building the Volkswagen eGon exhibit.

Seeing a super minimalist Volkswagen electric Golf on the move (short Twitter video embedded below) we are immediately reminded of circuit sculptures. We saw some great projects in our circuit sculpture contest, but the eGon shows what can be done with the resources of a Volkswagen training center. Parts are bolted to the car’s original structure where possible, the rest were held in their representative positions by thin metal tube frames. At this scale, they look just like the brass rods used in small circuit sculptures! Certain component enclosures were replaced with transparent pieces, or had a window cut into them for visibility.

This exhibit was built for IdeenExpo, an event to expose students to science and technology. Showing them what’s under the cover in this “see-through car” with internal components tagged with QR codes pointing them to additional information. The number of electronic modules inside a car is only going to continue rising with the coming wave of electric and/or self-driving cars. Even if the timing of their arrival is debatable, we know we’ll need brain power helping to answer questions we don’t even know to ask yet. The eGon is doing a great job attracting attention and inviting bright young minds to participate.

Solar Circuit Sculpture Pumms The Night Away

April 4, 2019 by 17 Comments

A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with.

For the unfamiliar, a pummer is a device from the BEAM style of robotics, a sort of cyborg plant that absorbs solar energy during the day and turns it into a gently pulsating light that “pumms” away the dark hours.

[Mohit Bhoite]’s take on the pummer is an extraordinary model of a satellite executed mainly in brass rod. His attention to detail on the framework boggles our minds; we could work for days on a brass rod and never achieve the straight lines and perfect corners he did. The wings support two solar cells, while the hull of the satellite holds a dead-bugged 74HC240 octal buffer/line-driver chip and all the other pumm-enabling components. A one farad supercap – mounted to look like a dish antenna – is charged during the day and a single LED beacon blinks into the night.

No schematic is provided, but there are probably enough closeup shots to reverse engineer this, which actually sounds like a fun exercise. (Or you can cheat and fetch the PDF copy of the old Make magazine article that inspired him.)

Hats off to [Mohit] for a top-notch circuit sculpture. We’ve seen similarly detailed and well-executed sculptures from him before; something tells us this won’t be the last.

Thanks to [Varun Reddy] for the tip.

Twelve Circuit Sculptures We Can’t Stop Looking At

January 15, 2019 by 25 Comments

Circuits are beautiful in their own way, and a circuit sculpture takes that abstract beauty and makes it into a purposeful art form. Can you use the wires of the circuits themselves as the structure of a sculpture, and tell a story with the use and placement of every component? Anyone can exercise their inner artist using this medium and we loved seeing so many people give it a try. Today we announce the top winners and celebrate four score of entries in the Hackaday Circuit Sculpture Contest.

Let’s take a look at twelve outstanding projects that caught (and held) our eye:

We’re Dreaming Of A Circuit Sculpture Christmas

December 21, 2018 by 6 Comments

Whether or not you chose to believe our claim that we planned it this way, the holidays happen to fall right smack in the middle of our ongoing Circuit Sculpture Contest, which challenges hackers to build circuits that double as bona fide works of art. It’s become almost too easy to spin up your own PCB, so why not try your hand at building in three dimensions and without a net? The holidays are a perfect time for it as it’s not only a reprieve from the work, school, or forced labor camp that usually ties up our waking hours, but can also be a source of inspiration.

Case in point, this festive LED Christmas tree entry that comes our way courtesy of [Vincent Mkes]. This one really has it all: a recognizable theme, fantastic wire work, copious amounts of LEDs, and in a touch that is sure to delight even the electronics Scrooges amongst our readership, he does it all with the venerable 555 timer. It’s really what the Circuit Sculpture Contest is all about: taking a circuit that might otherwise be pretty ordinary and turning it into something truly unique.

The astute Hackaday reader (as if there was any other type) will likely notice there are actually two NE555 timers under the tree, each blinking their respective bank of LEDs at a different frequency. This makes the final result a bit more vibrant, and through some last-minute revisions, [Vincent] was able to hook them both up to a single power supply to really capture the minimalist spirit of the Contest.

As an early Christmas gift to us all, [Vincent] has done an excellent job documenting this build so anyone who wishes to infuse their end of year party with a little diode-driven holiday cheer can follow along. He’s included build instructions as well as diagrams of the circuit, though we encourage anyone looking to make one of their own to experiment a bit and put their own spin on it. After all, this is supposed to be art.

There’s still plenty of time to get your own entry into the Circuit Sculpture Contest, Yule-related or otherwise. Just document your build on Hackaday.io and submit it before the January 8th, 2019 deadline. Remember that entries can’t just look cool, they still need to be functional. Words to live by in general, but doubly important when they’re the rules of a contest.

The Circuit Sculpture Contest

December 4, 2018 by 29 Comments

Many artists are inseparably associated with their medium: Vincent Van Gogh had oil paint, Auguste Rodin had bronze, and Banksy has the spraycan and stencil. You have ICs, passives, wire, and solder. So often electronics are hidden away, but not today! We want to see you build electronic circuits that are beautiful in and of themselves.

This is Hackaday’s Circuit Sculpture Contest and we bet you already have everything you need to enter. Leave behind the drab flatland of 2D PCBs and break out into the third dimension! Or break away from the PCB entirely. Our inspiration comes from a few recently featured projects by Mohit Bhoite and by Eirik Brandal that show functional electronic circuits supported by their own wiring:

There’s something beautiful in these works. They take what would be unnoticed traces and bring them to the forefront of the project. The core of the challenge is simple: built a sculpture where an electronic circuit is the main building material (or medium if you prefer the artistic vernacular).
