AI Dreaming Of Time Travel

September 28, 2022 by Matthew Carlson 20 Comments

We love the intersection between art and technology, and a video made by an AI (Stable Diffusion) imagining a journey through time (Nitter) is a lovely example. The project is relatively straightforward, but as with most art projects, there were endless hours of [Xander Steenbrugge] tweaking and playing with different parts of the process until it was just how he liked it. He mentions trying thousands of different prompts and seeds — an example of one of the prompts is “a small tribal village with huts.” In the video, each prompt got 72 frames, slowly increasing in strength and then decreasing as the following prompt came along.

There are other AI videos on YouTube, often putting the lyrics of a song into AI-generated form. But if you’ve worked with AI systems, you’ll notice that the background stays remarkably stable in [Xander]’s video as it goes through dozens of feedback loops. This is difficult to do as you want to change the image’s content without changing the look. So he had to write a decent amount of code to try and maintain visual temporal cohesion over time. Hopefully, we’ll see an open-source version of some of his improvements, as he mentioned on Twitter.

In the meantime, we get to sit back and enjoy something beautiful. If you still aren’t convinced that Stable Diffusion isn’t a big deal, perhaps we can do a little more to persuade your viewpoint.

laser cut acrylic coaster with rgb leds inside

Your Mug Will Like This Glowy Coaster

September 28, 2022 by Abe Connelly 2 Comments

[Charlyn] wanted to highlight their friends beautiful mug collection, so the Glowy Coaster was born.

The coaster is made up of six layers of laser cut acrylic. The top and bottom layer are cut out of clear acrylic, providing a flat surface for the coaster. A top pattern layer made of pearl acrylic has a thin piece of vellum put underneath it to provide diffusion for the LED strip sandwiched inside. The middle layers are made of peach acrylic and have their centers hollowed out to provide room for the electronics inside. The top pearl acrylic layer gives the coaster, as [Charlyn] writes, a “subtle touch of elegance”. The coaster itself is screwed together by an M3 screw at each point of the hexagon that feed through to heat-set inserts.

The electronics consist of a short NeoPixel strip, cut to include 12 LEDs pointed in towards the center of the coaster. The LEDs are driven by a Trinket M0 microcontroller with a LiPo “backpack” to provide power, attachment points for the exposed power switch and recharging capability to the 110 mAh 3.7 V battery. The code is a slightly modified NeoPixel “rainbow” wheel loop (source available as a gist). The design files are available through Thingiverse.

Creations like these highlight how much care and work goes into a project with minimal beauty, where decisions, like the opacity and thickness of the acrylic or countersinking the M3 screws, can have huge consequences for the overall aesthetic. [Charlyn] has an attention to detail that brings an extra touch of professionalism and polish to the project.

Coasters are a favorite for laser cutting and we’ve covered many different types, including
coaster bots, coaster engravers and even a color changing, drink sensing coasters.

3D-Printable Sculpture Shows Off Unpredictable Order Of Chains

September 25, 2022 by Donald Papp 7 Comments

[davemoneysign] designed this fascinating roller chain kinetic sculpture, which creates tumbling and unpredictable patterns and shapes as long as the handle is turned; a surprisingly organic behavior considering the simplicity and rigidity of the parts.

3D-printed, with a satisfying assembly process.

The inspiration for this came from [Arthur Ganson]’s Machine With Roller Chain sculpture (video, embeded below). The original uses a metal chain and is motor-driven, but [davemoneysign] was inspired to create a desktop and hand-cranked manual version. This new version is entirely 3D-printed, and each of the pieces prints without supports.

According to [davemoneysign], the model works well with a chain of 36 links, but one could easily experiment with more or fewer and see how that changes the results. Perhaps with the addition of a motor this design could be adapted into something like this chains-and-sprockets clock?

You can see [Arthur Ganson]’s original in action in the video embedded below. It demonstrates very well the piece’s chaotic and unpredictable — yet oddly orderly — movement and shapes. Small wonder [davemoneysign] found inspiration in it.

CMOS Oscillator Circuit Gets An Eatable Input

September 24, 2022 by Lee Wilkins 9 Comments

In interaction designer [Leonardo Amico]’s work Processing Decay, lettuce is used as an input to produce sound as an element within a CMOS circuit.

We’ve all seen lemons and potatoes doubling in science-fairs as edible batteries, but lettuce is something else. [Leandro]’s circuit uses alligator clips to insert lettuce into oscillators in this audio generating circuit — we think they’re behaving like resistors. Without refrigeration, the resistance of the lettuce changes, and so does the oscillation in the circuit. In a matter of hours, days, and weeks the cells degrades slowly, modulating the system and its sonic output. What a way to make music!

This hack isn’t the freshest — the video dates from nine years ago — but this is the first lettuce circuit we’ve seen. Of course, we love other food hacks like these multi-wavelength lasers used to cook 3D-printed chicken, or maybe the circuit can make use of this neural net detecting fruit ripeness.

Robots Chase Down Balls In Fun Outdoor Game

September 22, 2022 by Lewin Day 1 Comment

Art installations aren’t always about static sculpture or pure aesthetics. In the case of Operation Kiba, they can be fun games for everyone to enjoy.

The aim of Operation Kiba is for the players to collect all the “balls” on the playing field, which are intended to represent scoops of ice cream. Collecting the balls is done via robot. Each player is ostensibly tasked with collecting one color of ball or the other, but players often decide to work together in harmony instead. The balls are released at the start of the game by tipping over a big bowl. This is half the fun, and is achieved by tugging a string which upends the vessel and scatters the balls.

The remote-control robots themselves come from an earlier art installation the group built called Bubble Blast. They’re built using a 3D printed chassis, with wheels on each side driven by DC gear motors. With tank-style steering, they can rotate on the spot, providing good maneuverability. An Arduino Nano runs the show, receiving commands over a 433 MHz radio link. Power is via DeWalt cordless drill batteries, and the robots are controlled via arcade sticks. They’re color-coded to match the balls in the game.

As far as art installations go, it may not be fancy or pretentious, but it certainly looks like a lot of fun. We’re sure it could eventually guide many players towards the exciting world of antweight combat robotics. Video after the break.

Shot of CubeTouch, a six sided cube built out of PCBs with each of the top PCB allowing for diffusion of the LEDs on the inside to shine through

Keyboard Shortcuts At The Touch Of A Planetary Cube

September 19, 2022 by Abe Connelly 3 Comments

[Noteolvides] creates the CubeTouch, a cube made of six PCBs soldered together that creates a functional and interactive piece of art through its inlaid LEDs and capacitive touch sensors.

The device itself is connected through a USB-C connector that powers the device and allows it to send custom keyboard shortcuts, depending on which face is touched.

The CubeTouch is illuminated on the inside with six WS2812 LEDs that take advantage of the diffusion properties of the underlying FR4 material to shine through the PCBs. The central microprocessor is a CH552 that has native USB support and is Arduino compatible. Each “planet” on the the five outward facing sides acts as a capacitive touch sensor that can be programmed to produce a custom key combination.

Assembling the device involves soldering the connections at two joints for each edge connecting the faces.

We’re no strangers to building enclosures from FR4, nor are we strangers to merging art and functionality. The CubeTouch offers a further exploration of these ideas in a sweet package.

The CubeTouch is Open Source Hardware Certified with all documentation, source code and other relevant digital artifacts available under a libre/free license.

Glue-on nails with vinyl record pickups pierced through them that are used on a vinyl record

The Sound Of Nails On Black Vinyl Records

September 16, 2022 by Abe Connelly 32 Comments

[Victoria Shen] modifies glue-on nails to give her the ability to play vinyl records with her fingers. Details are light but from the many glamour pictures, it looks like she pushes record player needles through glue-on nails with thin pickup wire that then presumably goes to an audio jack for amplification.

[Victoria] experiments with novel musical tools for use in her art and performances. Be sure to check out the videos of the nails in action. The combination of “scratching” and ability to alter the speed of vinyl with the free fingers creates a weird and eerie experience.

Using her “Needle Nails”, [Victoria] has found she’s able to play multiple records simultaneously (Nitter). Thanks to the different diameters of 33, 78 and 45 vinyls, she’s able to stack them up while still keeping her fingers on them.

Glove like musical instruments are nothing new but the novel use of fashion, glamour and technology allow [Victoria Shen] the freedom to create something uniquely weird and cool, so much so that Beyonce used it in a video shoot for Vogue (Nitter).
