Is your temper hard but brittle? Meet the Anger Release Machine: a ware-dropping spiral vending machine stocked with precious porcelain.
There’s a bit more engineering and user experience design behind [Yarisal & Kublitz’s] art installation than meets the eye. The Anger Release Machine drops your purchase from dangerous heights, but like every passive aggressive vending machine, it also does its best to infuriate you using controlled disappointment. Insert a coin, see the steel spirals turn, and just when you’re already dying of the suspense…

Sequencers allow you to compose a melody just by drawing the notes onto a 2D grid, virtually turning anyone with a moderate feel for pitch and rhythm into an electronic music producer. For [Yuvi Gerstein’s] large-scale grid MIDI sequencer GRIDI makes music making even more accessible.
Instead of buttons, GRIDI uses balls to set the notes. Once they’re placed in one of the dents in the large board, they will play a note the next time the cursor bar passes by. 256 RGB LEDs in the 16 x 16 ball grid array illuminate the balls in a certain color depending on the instrument assigned to them: Drum sounds are blue, bass is orange and melodies are purple.
Underneath the 2.80 x 1.65 meters (9.2 x 4.5 foot) CNC machined, sanded and color coated surface of the GRIDI, an Arduino Uno controls all the WS2812 LEDs and reads back the switches that are used to detect the balls. A host computer running Max/MSP synthesizes the ensemble. The result is the impressive, interactive, musical art installation you’re about to see in the following video. What better tune to try out first than that of Billie Jean whose lighted sidewalk made such an impression on the original music video.

[dmitry] writes in to let us know about a new project that combines lasers with fans and turns the resulting modulation of the light beams into an autonomous soundscape. The piece is called “divider” and is a large, wall-mounted set of rails upon which seven red lasers are mounted on one end with seven matching light sensors mounted on the other end. Interrupting the lasers’ paths are forty-two brushless fans. Four Arduino Megas control the unit.
Laser beams shining into light sensors don’t do much of anything on their own, but when spinning fan blades interrupt each laser beam it modulates the solid beams and turns the readings of the sensors on the far end into a changing electrical signal which can be played as sound. Light being modulated by fan blades to create sound is the operating principle behind a Fan Synth, which we’ve discussed before as being a kind of siren (or you can go direct to that article’s fan synth demo video to hear what kind of sounds are possible from such a system.)
This project takes this entire concept of a fan synth further by not only increasing the number of lasers and fans, but by tying it all together into an autonomous system. The lasers are interrupted repeatedly and constantly, but never simultaneously. Listen to and watch it in action in the video below.

A Hodoscope is an instrument used to determine the trajectory of charged particles. It’s built out of a three-dimensional matrix of particle detectors – either PIN diodes or Geiger tubes – arranged in such a way that particles can be traced along coincident detectors, revealing their trajectory.
This is not a hodoscope. It’s a chandelier. This chandelier is made of 92 individual Geiger tubes, each connected to a single LED fixture and a speaker. When a charged particle flies through the room and hits a Geiger tube, the light fixture lights up, a ‘click’ plays on the speaker, and the entire room is enveloped in light for a short moment in time. If, however, that charged particle continues on to another Geiger tube, the trajectory of the particle can be deduced.
The purpose of the installation – beside just being art or something – is to show the viewer sources of radiation and normal levels of radioactivity due to terrestrial and cosmic sources. Of course the spacing of these detectors is rather large – it’s made to fit in a gallery – and there is no connection between the detectors, making a coincident circuit impossible. If you want a real hodoscope, here you go.
This installation can be seen at the Burchfield Penney Art Center in Buffalo, NY through April 12. If you’re in the area, go there and eat a banana. Video below. Thanks [David] for the tip.

[Brian Korsedal] and his company Arcology Now! have developed a great geodesic building system which makes architectural structures that aren’t just limited to domes. They 3D scan the terrain, generate plans, and make geodesic steel space frame structures which are easy to assemble and can be in any shape imaginable.
Their clever design software can create any shape and incorporate uneven terrains into the plans. The structures are really easy to construct with basic tools, and assembly is extremely straight forward because the pole labels are generated by the design software. Watch this construction time lapse video.
At the moment, ordering a structure fabricated by the company is your only option. But it shouldn’t be too hard to fabricate something similar if you have access to a hackerspace. It may even be worth getting in touch with Arcology now! as they do seem happy collaborating to make art like the Amyloid Project, and architectural structures for public spaces and festivals like Lucidity. Find out what they are up to on the Arcology Now! Facebook page.
Would this be perfect for what you’ve been thinking about building? Let us know what that ‘something’ is in the comments below. Continue reading “Geodesic Structures that aren’t just Domes”
The gang at Bolt.io realized that the walls in their office deserved some special attention, and they got it by mounting exploded hardware throughout the space. They sourced the used devices from eBay, then carefully broken them down into their components and mounted each on its own sheet of PETG. The result: exploded views of some of their favorite hardware, including a MacBook Pro, a Roomba, a Dyson Air Multiplier, and more.
Is it a hack? Eh, maybe. This is the first example we’ve seen of a collection of devices on display in this fashion. Regardless, it’s worth a mention considering what happened in the office as a result of the installation. Though the original purpose was simply to decorate the walls, it seems employees have been staring at them regularly, learning more about the designs, the plastics, and the component choices. Think of it as still life—depicting that moment you cracked open a device to inspect its guts—frozen in permanence and on display for both inspiration and convenience.

Looking for a neat decoration for your next soirée? How about floating fleet of glowing balloon blimps?
[Kensho Miyoshi] — an avid reader of Hack a Day — needed an art installation project in Tokyo, he came up with these clever glowing balloon blimps.
They feature a mini gondola hanging from the bottom of a regular balloon which holds a small motor with a propeller, an Arduino Pro Mini, LEDs, an ultrasonic sensor and of course, a battery. They float up to a certain height with the LEDs shining bright, and when the ultrasonic sensor trips, it all turns off and the balloon sinks gently back to the ground. The process repeats, and in a completely dark room it looks like a series of glowing bubbles forming and floating away, again and again.
To see the floaty, glowy, balloon blimps, stick around for a video after the break.
