The Tower, a discrete component circuit sculpture clock

A Breathtaking Circuit Sculpture Clock

November 10, 2021 by Dan Maloney 8 Comments

Here at Hackaday, we pride ourselves on bringing you the very freshest of hacks. But that doesn’t mean we catch all the good stuff the first time around, and occasionally we get a tip on an older project that really should have been covered the first time around. This remarkable circuit sculpture clock is a perfect example of one that almost got away.

[Gislain Benoit] creation is called “The Tower” for good reason: it’s built inside what amounts to a giant glass test tube. Inverted and adorned with MDF discs, the Pyrex tube stands 5 feet (1.5 meters) tall, and is absolutely stuffed with electronic goodness. There are more than 2,100 discrete components mounted inside on a helical framework of carefully bent wires, forming a vertical sculpture that displays the time on three separate pairs of seven-segment displays. All the diode-transitor logic circuits are built from discrete components; nary a chip was used, and to spice things up, [Gislain] used LEDs in place of regular diodes everywhere in the circuit. The result is a constant light show as the clock goes through its paces.

The whole thing looks amazing, and even the power supply at the base works in the overall presentation. The design is a bit of a departure from [Gislain]’s previous circuit sculpture clock, but it’s just as beautiful, and equally as mind-boggling in terms of construction difficulty.

Thanks to [Maarten] for the belated tip on this one.

Labyrinthian Circuit Sculpture Evokes Moods With Sound And Light

October 20, 2021 by Ryan Flowers 5 Comments

In a famous letter penned by Victorian era author Oscar Wilde, he wrote:

“Art is useless because its aim is simply to create a mood. It is not meant to instruct, or to influence action in any way. It is superbly sterile, and the note of its pleasure is sterility.”

We can’t help but wonder if [Eirik Brandal] was evoking such Wilde thoughts when he wrote to tell us about ddrysfeöd, an electronic sound and light sculpture which he called “uselessly applied electronics.” Given the mood created by the video below the break, we have to agree that it is indeed quite artful. But if it serves a purpose to inspire and cause wonderment, is it really useless? Let the philosophers philosophize. On to the hack!

[Eirik] was himself inspired by mazes such as those found in children’s activity books and magazines whose goal is to keep a child ~~busy~~ challenged by drawing a solid line from start to finish. With these in mind, [Eirik] constructed ddrysfeöd as an intricate entanglement of electronics, metal, clear and mirrored acrylic, and plated steel, all flung into a three dimensional vortex.

LED’s of red and white oscillate in time with each other. Orchestrating the multimedia symphony is an ESP32, with one core relegated to dealing with the mundane functions of the sculpture while the other waves its electronic wand to keep the ensemble suitably arranged. LED’s are bored into the base, and the acrylic is sanded on the edges to diffuse the supplied light. The electronics run on the usual +5 V, but a +12 V power supply gives volume to the LM380 audio amplifier. We also appreciated that [Eirik] expanded his skills on this project by using Sketchup to plan out the project, even printing the patterns for cutting and drilling the acrylic glass.

If [Eirik]’s build style looks familiar, it may be because you’ve seen it here on Hackaday’s Circuit Sculpture Contest, where some of his work was named Most Beautiful. You can also feast your eyes on a BEAM bot inspired pummer in the shape of a satellite. And remember, if you run across something that presses your buttons, let us know via the Tip Line!

Circuit Sculpture Vibration Sensor

January 10, 2021 by Kristina Panos 15 Comments

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those vibrations you expect, like laundry machines, or those you only suspect, like the kind that might be coming from your engine. This gadget isn’t super-precise, but it will probably get the job done.

The vibration-detecting bit is a tiny ball bearing soldered to the spring from an old pen, which is tied between the trigger and ground pins of the 555. When the chip is powered with a 9 V battery, nearby vibrations will induce wiggle in the spring, causing the ball bearing to contact the brass rod and completing the circuit. When this happens, the internal flip flop’s output goes high, which turns on the LED. Then the flip flop must be reset with a momentary button. Check out the build video after the break.

Want to pick up Earthly vibrations? You can detect earthquakes with a homemade variable capacitor, a 555, and a Raspberry Pi.

Remoticon Video: Circuit Sculpture Workshop

December 3, 2020 by Kristina Panos 1 Comment

Circuit Sculpture was one of our most anticipated workshops of Hackaday Remoticon 2020, and now it’s ready for those who missed it to enjoy. A beginning circuit sculptor could hardly ask for more than this workshop, which highlights three different approaches to building firefly circuit sculptures and is led by some of the most prominent people to ever bend brass and components to their will — Jiří Praus, Mohit Bhoite, & Kelly Heaton.

For starters, you’ll learn the different tools and techniques that each of them uses to create their sculptures. For instance, Kelly likes to use water-based clay to hold components in specific orientations while forming the sculpture and soldering it all together. Jiří and Mohit on the other hand tend to use tape. The point is that there is no right or wrong way, but to instead have all of these tips and tricks under your belt as you sculpt. And that’s what this workshop is really about.

No Wonder These Projects Won The Circuit Sculpture Contest

November 20, 2020 by Mike Szczys 5 Comments

There are five winners of the Hackaday Circuit Sculpture contest, and every one of them comes as no surprise, even in a tightly packed race to the top.

Beginning with the gorgeous photo above, we have [Eirik Brandal’s] waldian being named the most beautiful. Imagine this hanging on your living room wall, then head over and listen to the video demo as it’s light-actuated synthesizer chimes like distant (or maybe not so distant) church bells. This isn’t a one-off dip into circuit sculpture for [Eirik], we featured his broader body of work back in 2018, all of it worth checking out in more depth.

The glowing mask is actually made of PCB. The seams are secured with super glue bolstered with baking soda. The labor behind this one is intense. As we mention back in September, the project took place over about two years, mostly due to the sheer volume of cutting and sanding [Stephen Hawes] needed to do to bring together so many pieces. This one grabbed him the most artistic award.

[Jiří Praus] takes the top spot for best video with his luminescent RGB LED sphere. We swooned over this one when it first dropped back in December. [Jiří] shows off a combination of patience and ingenuity by using a 3D-printed mold to hold each LED while he soldered brass rod in place to serve as both electrical and mechanical support.

Speaking of molds, one of the challenges was to show off the best jig for creating a circuit sculpture. [Inne’s] Soft Soldering Jig provides the channels needed to keep crisp right angles on the brass rod as you work, with voids to position components at intersections for soldering. Drawing on the advice of numerous circuit sculpture success from people like [Mohit Bohite] and [Jiří Praus], he was looking for a way to easily position everything on a surface that would not be burnt by the soldering iron. The answer comes in the form of Silicone jigs made with 3D-printed molds.

Finally we have the Binary Calculator project which won the most functional award. While it does operate as a binary calculator, the beauty of it is not to be overlooked. Among its many attributes are a set of cherry-wood keycaps that were milled for the project and a bell-jar display stand where the calculator rests and serves as a binary clock when not in use. You may remember seeing our feature of this project last week.

As prizes, the binary calculator, orb, and wall sculpture creators will each be receiving $200 in goodies from Digi-Key who sponsored the contest and will be featuring entries in a 2021 wall calendar. Creators of the soldering jig and the PCB mask will receive a $100 Tindie gift card.

Circuit Sculpture Breathes Life Into Discrete Components

October 27, 2020 by Kristina Panos 5 Comments

We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say the best art imitates life, and [bornach]’s Astable Exhalation certainly does that, right down to the part about astability. It’s especially interesting that the end result — breathing, visualized — is so calming, it could almost be a meditative device.

There is nary a microcontroller to be found on this circuit sculpture, which uses a pair of astable multivibrator(s) to light two sets of LEDs that represent air being inhaled and exhaled. We like that [bornach] used two sized of exhale LEDs to represent droplets and aerosols in this beautiful circuit sculpture, and we love that most of the components were scavenged from old electronics and older projects.

Our Circuit Sculpture Challenge runs until November 10th, so even if you’re waiting to take the Remoticon workshop before entering, there’s still a little bit of time to whip something up afterward in the post-con adrenaline rush phase. If you need inspiration, check out some of the other contest entries or just surf through all things circuit sculpture.

New Contest: Circuit Sculpture Challenge

August 18, 2020 by Mike Szczys No comments

We’re bringing back one of our most popular contests, the Hackaday Circuit Sculpture Challenge! Make your functional circuits go beyond utility by turning them into art!

Solar-powered circuit sculpture by [Mohit Bhoite] which was featured last year.

Wire and circuit boards are a fantastic media for creating beautiful projects, and for this one we want both the copper and the boards (or lack of) to be part of the beauty. Your sculpture could be crisp and angular bends in brass rod, a rat’s nest of enamel wire, PCBs with organic shapes, or something completely wild. Your only constraint is that there needs to be some type of working circuit involved.

Three entries will be chosen as top winners in the Most Functional, Most Beautiful, and Best Video categories and be awarded $200 in components from Digi-Key who are sponsoring this contest and also putting together a calendar with images of the top twelve sculptures.

The *Wonderlandscape* by [Michael Aichlmayr] takes the “sculpture” part of Circuit Sculpture to new levels.

Tell us the story of your creation, including a deep dive into how you built the sculpture and what trial and error you went through to pull it off. Many circuit sculptures in the past have included jig-building to get the wire bends just right, so we have a fourth prize of $100 in Tindie credit for the Best Jig build.

Get your project started now on Hackaday.io and use that “Submit Project To:” button in the left sidebar of your project page to enter it in the Circuit Sculpture Challenge. You have until November 10th to submit your entry.
