Circuit Sculpture Lamp Is A Colorful Cube Companion

November 15, 2021 by Lewin Day 10 Comments

Circuit sculpture is engineering and art all at play together. One must combine the functional with the aesthetically appealing. [EdwardA61] did just that with this enchanting lamp build.

Like many other circuit sculptures, the build relies on the aesthetic qualities of brass, though [EdwardA61] notes that copper wire can be used as well. Four WS2812B LEDs, in their bare PCB-mount form, are soldered into a circuit using the brass to carry the power and data signals as needed.

A Seeduino Xiao microcontroller is responsible for controlling the show, though relies on a typical PCB rather than a circuit sculpture in and of itself. It does provide for easy powering and programming however, with the benefit of its USB-C connector.

It’s a simple skeleton design, as so many circuit sculptures are, but it’s a form that we’ve come to love and appreciate. [EdwardA61] did a great job of photographing the build, too, showing how the colors on each LED interplay with each other as they’re cast on the table.

It’s a lamp we’d love to build ourselves, and we hope that [EdwardA61] follows through on plans to cast a similar design in clear resin, as well. If you’ve built your own artistically electrical sculptures, be sure to let us know!

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.

ddrysfeöd circuit art sound and light scultpture

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!

Close up shot of a mechanical sequencer for 555 based synthesizers

Kinetic Synth-Kebab Sculpture Plays Punk Sequentially

October 4, 2021 by Ryan Flowers 12 Comments

What’s better than an Atari Punk Console synthesizer? How about four Atari Punk Console synthesizers. And what better way to present them but as brass wire art sculptures. We’d have forgiven [iSax] if he’d stopped at four brass wire synths, but he took things to another level with his kinetic sculpture that does double duty as a mechanical sequencer. Called the Cyclotone – The Mechanical Punk Console Sequencer, it features wood, brass, brushes, and 555 timers. You can see the demonstration in the video below the break.

If you’re not familiar with the Atari Punk Console, it’s a circuit first described as a “Sound Synthesizer” in Forest Mims’ “Engineer’s Notebook: Integrated Circuit Applications” first published in 1980. It utilized two 555 timers in a single chip, the 556. Later dubbed the “Atari Punk Console”, the circuit has stood the test of time and is still quite popular among hackers of all sorts.

[iSax]’s build adds a sequencing element that allows the synths to be played automatically. The synthesizers are skewered 90 degrees from each other on a square dowel, which is turned at a variable RPM by a stepper motor controlled by a knob at the base of the sculpture.

On either side of each synth is a commutator that contacts salvaged rotary tool brushes which provide power through the hexagonal brass supports. Each synth retains its own speaker and controls and has its own segmented numeral displayed with discrete LED’s that light up when each synth is played.

We applaud [iSax] for a well executed and imaginative build that successfully meshes circuit scultpure, kinetic sculpture, classic electronics and even blinkenlights. If you enjoyed this build, you should also go have a look at a free form Atari Punk Console build and another one built into a joystick. If you come across a project of any kind that catches your fancy, be sure you let us know about it via the Tip Line!

Hackaday Links: September 26, 2021

September 26, 2021 by Dan Maloney 33 Comments

Dealing with breakdowns is certainly nothing new for drivers; plenty of us have had our ride die in mid-flight, and experienced the tense moment when it happens in traffic. But the highly integrated and instrumented nature of the newest generation of electric vehicles can bring an interesting twist to the roadside breakdown, if the after-action report of a Tesla driver is any indication.

While driving on a busy road at night, driver [Pooch] reports that his Tesla Model S started beeping and flashing warnings to get to the side of the road right away. [Pooch] tried to do so, but the car died, coasted to a stop in the middle of the road, and engaged the parking brakes. The bricked Tesla would have been a sitting duck in the middle of the road but for a DOT crew who happened to be nearby and offered to provide some protection while [Pooch] waited for help. The disturbing part was the inability to get the car into any of the service modes that might let it be pushed off to the shoulder rather than stuck in traffic, something that’s trivial to do in ICE vehicles, at least older ones.

In other electric vehicle news, Chevy Bolt owners are turning into the pariahs of the parking garage. General Motors is telling Bolt EV and EUV owners that due to the risk of a battery fire, they should park at least 50 feet (15 meters) away from other vehicles, and on the top level of any parking structures. There have been reports of twelve battery fires in Bolts in the US recently, which GM says may be due to a pair of manufacturing defects in the battery packs that sometimes occur together. GM is organizing a recall to replace the modules, but isn’t yet confident that the battery supplier won’t just be replicating the manufacturing problem. The social distancing rules that GM issued go along with some fairly stringent guidelines for charging the vehicle, including not charging overnight while parked indoors. With winter coming on in the northern hemisphere, that’s going to cause a bit of inconvenience and probably more than a few cases of non-compliance that could end in tragedy.

Fans of electronic music might want to check out “Sisters with Transistors”, a documentary film about some of the pioneering women of electronic music. Electronic music has been around a lot longer than most of us realize, and the film reaches back to the 1920s with Theremin virtuoso Clara Rockmore, and continues on into the 1980s with Laurie Spiegel, whose synthesizer work has been speeding away from Earth for the last 44 years on the Golden Records aboard the Voyager spacecraft. Hackaday readers will no doubt recognize some of the other women featured, like Daphne Oram and Delia Derbyshire, who cobbled together the early Dr. Who music with signal generators, tape loops, and random bits of electronics in the pre-synthesizer days of the early 60s. We’ve watched the trailer for the film and it looks pretty good — just the kind of documentary we like.

We’re big fans of circuit sculpture around here, and desperately wish we had the patience and the skill to make something like Mohit Bhoite or Jiri Praus can make. Luckily, there’s now a bit of a shortcut — Geeek Club’s Cyber Punk PCB Construction Kit. These kits are a little like the love child of Lego and PCBWay, with pieces etched and cut from PCB stock. You punch the pieces out, clean up the mouse bites, put Tab A into Slot B, and solder to make the connection permanent. Each kit has some components for the requisite blinkenlight features, which add to the cool designs. Looks like a fun way to get someone started on soldering, or to build your own skills.

And finally, another nail was driven into the coffin of Daylight Savings Time this week, as the island nation of Samoa announced they wouldn’t be “springing ahead” as scheduled this weekend. Daylight Savings Time has become a bone of contention around the world lately, and mounting research shows that the twice-yearly clock changes cause more trouble than they may be worth. In Europe, it’s due to be banned as soon as all the member nations can agree on normal time or summer time.

In the case of Samoa, DST was put into effect in 2010 on the assumption that it would give plantation workers more productive hours in the field and save energy. Instead, the government found that the time change just gave people an excuse to socialize more, which apparently upset them enough to change the rule. So there you have it — if you don’t like Daylight Savings Time, start partying it up.

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.

Binary Calculator For All 0b10 Types

November 10, 2020 by Dan Maloney 15 Comments

You know the old joke: There are 10 types of people in the world — those who understand binary, and those who don’t. Most of us on Hackaday are firmly in the former camp, which is why projects like this circuit sculpture binary calculator really tickle our fancies.

Inspired by the brass framework and floating component builds of [Mohit Bhoite], [dennis1a4] decided to take the plunge into circuit sculpture in an appropriately nerdy way. He wisely decided on a starter build, which was a simple 555 timer circuit, before diving into the calculator. Based on an ATMega328P in a 28-pin DIP, the calculator is built on an interesting hybrid platform of brass wire and CNC-routed wood. The combination of materials looks great, and we especially love the wooden keycaps on the six switches that make up the keyboard. There’s also some nice work involved in adapting the TLC5928 driver to the display of 16 discrete LEDs; suspended as it is by fine magnet wires, the SSOP chip looks a bit like a bug trapped in a spider web.

Hats off to [dennis1a4] for a great entry into our soon-to-conclude Circuit Sculpture Contest. The entry deadline is (today!) November 10, so it might be a bit too late for this year. But rest assured we’ll be doing this again, so take a look at all this year’s entries and start thinking about your next circuit sculpture build.
