[Benjamin Grosser] had a simple question: “What does Mark Zuckerberg think about?” The resulting art project is named ORDER OF MAGNITUDE and to create it he researched archives of every public utterance the founder and CEO of the world’s largest social media network has made, going as far back as 2004.
The end product is a nearly fifty-minute film consisting entirely of cuts centered around what [Benjamin] says are three of the Facebook CEO’s most favored and often-used terms:
The word “more”
The word “grow”
Metrics such as “ninety-nine percent”, “two million”, and terms of that nature.
The idea is that the resulting video provides insight into what Mark Zuckerberg thinks about, has focused on, and how that has (or has not) changed between 2004 and now. How well does ORDER OF MAGNITUDE do that? Watch the video below, and judge for yourself.
The inspiration for this project actually comes from something [Josef] had worked on previously: an ESP8266-based environmental monitoring system. That device had sensors to pick up on things such as humidity and ambient light level, but it didn’t have a display of its own; it just pushed the data out onto the network using MQTT. So he thought a companion device which could receive this environmental data and present it to him in a unique and visually appealing way would be a natural extension of the idea.
As the display doesn’t need any local sensors of its own, it made the design and construction much easier. Which is not to say it was easy, of course. In this write-up, [Josef] takes the reader through the process of designing each “layer” of the circuit in 2D, printing it out onto paper, and then using that as a guide to assemble the real thing. Once he had the individual panels done, he used some pieces of cardboard to create a three dimensional jig which helped him get it all soldered together.
On the software side it’s pretty straightforward. It just pulls the interesting bits of information off of the network and displays it on the OLED. Right now it’s configured to show current temperature on the display, but of course that could be changed to pretty much anything you could imagine if you’re looking to add a similar device to your desktop. There’s also a red LED on the device which lights up to let [Josef] know when the batteries are getting low on the remote sensor unit; a particularly nice touch.
CDs were a great advancement in audio quality when they were first put on the market. There’s no vinyl-style degradation of the medium if it’s played over and over, and there’s no risk of turning them into a giant pile of ribbon while rewinding like a cassette tape. The one downside was that if you were to take them on the move you needed special hardware and software to prevent the inevitable skipping. If you look at the skipping not as a downside, though, but as a way to produce interesting music, you might end up with a pretty unique piece of hardware.
[Dmitry] is known for his interesting art installations, and the latest one uses parts from three 1988 Sony D2 CD players that have been reassembled in order to take advantage of a skipping and glitching CD. The modified equipment is able to play during pause or rewind thanks to a processor modification, and can also change the rotational speed of the disc. There are other pieces of hardware included for more fine control of glitching and skipping of the audio being read off of the CD.
We see all manner of electronics enclosures pass through these hallowed pages. Lasercut wooden builds with fancy kerf bending, expertly prepared acrylic boxes, and even the occasional device cast in concrete. [Mike Kohn] decided that all of these were too permanent, however, and chose a different material – ice.
[Mike] shares the ups and downs of his experiments with electronics and frozen water. Initial tests with a circuit sealed in DAP Ultra Clear were largely successful. A tilt sensor was installed to allow the batteries to remain undrained during the freezing process, and once freed after a few hours of thawing, the circuit was operational. Later builds required some more work – the RC car in particular took a few attempts to avoid the mold leaking. The ice hands are a particular highlight, though – created with rubber gloves, these would be a remarkably spooky decoration come Halloween.
It’s a study in the techniques required to work with this ephemeral material, and there’s a few lessons to learn. Sealing electronics is good, and the best results are with simple circuits with a few LEDs that make everything glow nicely.
We rarely take a moment to consider the beauty of the components we use in electronic designs. Too often they are simply commodities, bought in bulk on reels or in bags, stashed in a drawer until they’re needed, and then unceremoniously soldered to a board. Granted, little scraps of black plastic with silver leads don’t exactly deserve paeans sung to their great beauty – at least not until you cut them in half to reveal the beauty within.
We’ve seen a little of what [Tube Time] has accomplished here; recall this lapped-down surface-mount inductor that [electronupdate] did a while back. The current work is more extensive and probably somewhat easier to accomplish because [TubeTime] focused mainly on larger through-hole components such as resistors and capacitors. It’s not clear how the sections were created, but it is clear that extreme care was taken to lap down the components with enough precision that the inner structures are clearly visible, and indeed, carefully enough that some, most notably the LED, still actually work. For our money, though, the best looking cross-sections are the capacitors, especially the electrolytic, for which [Tube Time] thoughtfully provides both radial and axial sections. The little inductor is pretty cool too. Some of the component diagrams are annotated, too, which makes for fascinating reading.
Honestly, we could look at stuff like this all day.
We’re all familiar with the subtle sounds of electrical equipment present in daily life. There’s the high-pitched whine of a CRT, the mains hum of a poorly isolated audio amplifier, and the wailing screams of inductors. Typically these sounds go unnoticed unless something is malfunctioning or otherwise wrong. However, Quiet Ensemble decided to capture these noises and turned them into a performance they call The Enlightenment.
The basic setup consists of a series of lights, most of which are theatrical in nature. There are spotlights, a series of neons, and even a few bright strobes. Copper coils are used to pick up the stray electrical noises generated by these lights in operation. These noises are then fed to mixers, amplifiers, and other audio equipment to allow the performers to control the audio as they wish.
The end result is a mechanical, and at times, brutal soundscape that wouldn’t sound out of place on the Homeworld soundtrack. Flashing strobes contribute rhythm while the rest of the lights lend their droning and whining to fill out the ensemble.
Lasercutters are amazingly versatile tools that can help you build all manner of complicated structures if you can break them down into a series of planar parts. [David] had spotted artworks at the Smithsonian which caught his eye, using planar shapes with interesting repeating patterns. Wanting to make similar works himself, he set out to create software to help make it possible.
The result of [David]’s work is the Polygonia Design Suite. It’s a tool that aims to make creating geometric patterns for lasercutting easy and simple. The web interface designer has a wide variety of options for drawing shapes and patterns, and the frame size can also be controlled. [David] demonstrates these features with all manner of creations. The project’s Instagram page features basic rectangular panels with inset cubic and triangular motifs, all the way up to an ornate octahedron built from many panels held together with 3D printed clips.
If you’re in the mood to create some geometric lasercut artworks, check out the tool online. The first 3 exports are free, with a variety of subscription models available for heavy users. We fully expect to see an explosion in fancy lasercut homewares at the weekend markets in years to come.
