Exquisite Craftsmanship Elevate Vic’s Creations Above The Rest

June 16, 2019 by 10 Comments

This booth was easy to miss at Maker Faire Bay Area 2019 amidst tall professional conference signage erected by adjacent exhibitors. It showcased the work of [Dr. Victor Chaney] who enjoys his day job as a dentist and thus feels no desire to commercialize his inventions — he’s building fun projects for the sake of personal enjoyment which he simply calls Vic’s Creations. Each project is built to his own standards, which are evidently quite high judging by the perfect glossy finish on every custom wood enclosure.

Some of these creations were aligned with his musical interests. The Backpacking Banjo was built around a (well cleaned) cat food can to satisfy the desire for a lightweight instrument he can take camping. His Musical Laser Rainbow Machine (fully documented in Nuts & Volts) was created so little bands formed by independent artists like himself can have a visual light show to go with their live performances. The Music Kaleidoscope is another execution along similar lines, with an LED array whose colors are dictated by music. Venturing outside the world of music, we see a magnetically levitated Castle In The Clouds which also receives power wirelessly to illuminate LEDs

The largest and most complex work on display is an epic electromechanical masterpiece. Par One is a rolling ball sculpture featuring the most convoluted golf course ever. Several more rolling ball sculptures (also called marble machines or marble runs) are on display at Dr. Chaney’s office which must make it the coolest dentist’s lobby ever. The lifelike motions he was able to get from the automatons he built into the sculpture are breathtaking, as you can see below.

Wonderful Sculptural Circuits Hide Interactive Synthesizers

November 29, 2018 by 14 Comments

When it rains, it pours (wonderful electronic sculpture!). The last time we posted about freeform circuit sculptures there were a few eye-catching comments mentioning other fine examples of the craft. One such artist is [Eirik Brandal], who has a large selection of electronic sculptures. Frankly, we’re in love.

A common theme of [Eirik]’s work is that each piece is a functional synthesizer or a component piece of a larger one. For instance, when installed the ihscale series uses PIR sensors to react together to motion in different quadrants of a room. And the es #17 – #19 pieces use ESP8266’s to feed the output of their individual signal generators into each other to generate one connected sound.

Even when a single sculpture is part of a series there is still striking variety in [Eirik]’s work. Some pieces are neat and rectilinear and obviously functional, while others almost looks like a jumble of components. Whatever the style we’ve really enjoyed pouring through the pages of [Eirik]’s portfolio. Most pieces have demo videos, so give them a listen!

If you missed the last set of sculptural circuits we covered this month, head on over and take a look at the flywire circuits of Mohit Bhoite.

Flywire Circuits At The Next Level

November 19, 2018 by 39 Comments

The technique of assembling circuits without substrate goes by many names; you may know it as flywiring, deadbugging, point to point wiring, or freeform circuits. Sometimes this technique is used for practical purposes like fixing design errors post-production or escaping tiny BGA components (ok, that one might be more cool than practical). Perhaps our favorite use is to create art, and [Mohit Bhoite] is an absolute genius of the form. He’s so prolific that it’s difficult to point to a particular one of his projects as an exemplar, though he has a dusty blog we might recommend digging through [Mohit]’s Twitter feed and marveling at the intricate works of LEDs and precision-bent brass he produces with impressive regularity.

So where to begin? Very recently [Mohit] put together a small wheeled vehicle for persistence of vision drawing (see photo above). We’re pretty excited to see some more photos and videos he takes as this adorable little guy gets some use! Going a little farther back in time there’s this microcontroller-free LED scroller cube which does a great job showing off his usual level of fit and finish (detail here). If you prefer more LEDs there’s also this hexagonal display he whipped up. Or another little creature with seven segment displays for eyes. Got those? That covers (most) of his last month of work. You may be starting to get a sense of the quality and quantity on offer here.

We’ve covered other examples of similar flywired circuits before. Here’s one of [Mohit]’s from a few years ago. And another on an exquisite headphone amp encased in a block of resin. What about a high voltage Nixie clock that’s all exposed? And check out a video of the little persistence of vision ‘bot after the break.

Thanks [Robot] for reminding us that we hadn’t paid enough attention to [Mohit]’s wonderful work!

Return Of The Infamous Triforium

October 19, 2018 by 2 Comments

The Triforium is a public art installation in Los Angeles, weighing 60 tons and standing six stories tall. Built in 1975, it was designed to combine light and sound, all under the control of computer hardware of the era.

Sadly, it was plagued with technical problems from the start, and over the years, became an object of ridicule. However, this “polyphonoptic” masterpiece will live once again, thanks to the dedicated effort of The Triforium Project. The Triforium Project are hosting a series of free public performances on Friday nights in October and November, so if you’re in the area, be sure to check it out. The series starts tonight, so get on it!

The team were able to recover the original software that ran the sculpture’s effects — stored on 8-bit paper tape, which was not uncommon for the era. These were manually transcoded, and an emulated version of the original program has been created. In the interest of not causing further damage to the sculpture, the original lights are being left untouched. Instead, an LED system will be fitted to the sculpture to enable it to be relit.

Quartz bells of the original carillon

A reflection pool at the base of the sculpture is long gone, as is the original audio source. When first built it housed a carillon — a musical instrument that uses a bell for each note in the scale. In the case of the Triforium, the carillon was made of 79 quartz bells played either manually or by the computer and amplified over a speaker system.

In 2006 that carillon was removed (replace with a digital audio source) but the gods of dumpster diving were smiling that day. It was snapped up by someone who recognized the uniqueness of the instrument and shared their story as a brief webpage. We hope that some day this will also be restored to working condition and played along with the Triforium in an exhibition. The sound of a carillon is amazing to hear in person, and we suspect the timbre of quartz bells to add an indescribable layer to the experience.

For those who can’t make it to an upcoming public performance, you can at least get a feel for the scupture through Google Street View. We do love a good public art piece here at Hackaday — whether it’s a giant head, a set of wings, or doodles in the sand.

Marble Chooses Its Own Path

March 6, 2018 by 16 Comments

[Snille]’s motto is “If you can’t find it, make it and share it!” and we could not agree more. We wager that you won’t find his Roball sculpture on any shopping websites, so it follows that he made, and subsequently shared his dream. The sculpture has an undeniable elegance with black brackets holding brass rails all on top of a wooden platform painted white. He estimates this project took four-hundred hours to design and build and that is easy to believe.

Our first assumption was that there must be an Arduino reading the little red button which starts a sequence. A 3D-printed robot arm grasps a cat’s eye marble and randomly places it on a starting point where it invariably rolls to its ending point. The brains are actually a Pololu Mini Maestro 12-channel servo controller. The hack is using a non-uniform marble and an analog sensor at the pickup position to randomly select the next track.

If meticulously bending brass is your idea of a good time, he also has a video of a lengthier sculpture with less automation, but it’s bent brass porn. If marbles are more your speed, you know we love [Wintergatan] and his Incredible Marble Music Machine. If that doesn’t do it for you, you can eat it.

Amazing Mechanical Linkages And The Software To Design Them

January 26, 2018 by 45 Comments

Most of us are more bits-and-bytes than nuts-and-bolts, but we have the deepest appreciation for the combination of the two. So, apparently, does [rectorsquid]. Check out the design and flow of his rolling ball sculpture (YouTube, embedded below) to see what we mean. See how the arms hesitate just a bit as the ball is transferred? See how the upper arm gently places it on the ramp with a slight downward gesture? See how it’s done with one motor? There’s no way [rectorsquid] designed this on paper, right?

Of course he didn’t (YouTube). Instead, he wrote a simulator that lets him try out various custom linkages in real time. It’s a Windows-only application (sigh), but it’s free to use, while the video guides (more YouTube) look very comprehensive and give you a quick tour of the tool. Of special note is that [rectorsquid]’s software allows for sliding linkages, which he makes very good use of in the rolling ball sculpture shown here.

We’ve actually secretly featured [rectorsquid]’s Linkage software before, in this writeup of some amazing cosplay animatronic wings that used the program for their design. But we really don’t want you to miss out if you’re doing mechanical design and need something like this, or just want to play around.

If you’d like to study up on your nuts and bolts, check out our primer on the ubiquitous four-bar linkage, or pore through Hackaday looking for other great linkage-powered examples, like this automatic hacksaw or a pantograph PCB probe for shaky hands.

Anyone know of an open-source linkage simulator that can also output STL files for 3D printing? Or in any format that could be easily transformed into OpenSCAD? Asking for a “friend”.

Engineering And Artistry Meet An Untimely End At Burning Man

October 6, 2017 by 38 Comments

Burning Man is so many different things to so many people, that it defies neat description. For those who attend, it always seems to be a life-changing experience, for good or for ill. The story of one man’s Burning Man exhibition is a lesson in true craftsmanship and mind-boggling engineering, as well as how some events can bring out the worst in people.

For [Malcolm Tibbets], aka [the tahoeturner], Burning Man 2017 was a new experience. Having visited last year’s desert saturnalia to see his son [Andy]’s exhibition, the studio artist decided to undertake a massive display in his medium of choice — segmented woodturning. Not content to display a bamboo Death Star, [Malcolm] went big– really big. He cut and glued 31,000 pieces of redwood into rings of various shapes and sizes and built sculptures of amazing complexity, including endless tubes that knot and loop around and back into each other. Many of the sculpture were suspended from a huge steel tripod fabricated by [Andy], forming an interactive mobile and kinetic sculpture.

Alas, Burning Man isn’t all mellowness in the desert. People tried to climb the tripod, and overnight someone destroyed some of the bigger elements of the installation. [Malcolm] made a follow-up video about the vandalism, but you’ll want to watch the build video below first to truly appreciate the scale of the piece and the loss. Here’s hoping that [Malcolm]’s next display is treated with a little more respect, like this interactive oasis from BM 2016 apparently was.

Thanks to [Keith Olson] for the tip.
