Give some mundane, old gear to an artist with a liking for technology, and he can turn it into a mesmerizing piece of art. [dmitry] created “red, an optic-sound electronic object” which uses simple light sources and optical elements to create an audio-visual performance installation. The project was the result of his collaboration with the Prometheus Special Design Bureau in Kazan, Russia. The inspiration for this project was Crystall, a reconstruction of an earlier project dating back to 1966. The idea behind “red” was to recreate the ideas and concepts from the 60’s ~ 80’s using modern solutions and materials.

The main part of the art installation consists of a ruby red crystal glass and a large piece of flexible Fresnel lens, positioned in front of a bright LED light source. The light source, the crystal and the Fresnel lens all move linearly, constantly changing the optical properties of the system. A pair of servos flexes and distorts the Fresnel lens while another one flips the crystal glass. A lot of recycled materials were used for the actuators – CD-ROM drive, an old scanner mechanism and old electric motors. Its got a Raspberry-Pi running Pure Data and Python scripts, with an Arduino connected to the sensors and actuators. The sensors define the position of various mechanical elements in relation to the range of their movement. There’s a couple of big speakers, which means there’s a beefy amplifier thrown in too. The sounds are correlated to the movement of the various elements, the intensity of the light and probably the color. There’s two mechanical paddle levers hanging in there, if you folks want to hazard some guesses on what they do.

Check out some of [dmitry]’s earlier works which we featured. Here’s him Spinning a Pyrite Record for Art, and making Art from Brainwaves, Antifreeze, and Ferrofluid.

Anyone with a record player is familiar with the concept of translating irregularities on a surface into sound. And, anyone who has ever cracked open a CD player or DVD player has seen how a laser can be used to reproduce sound digitally. Combining the two would be an interesting project in its own right, but [Dimitry Morozov] took this a couple of steps further with his pyrite disc sound object project.

Pyrite discs, also known as pyrite suns or pyrite dollars, are a form of pyrite in which the crystallization structure forms a disc with radial striations. Pyrite discs are unique to the area around Sparta, Illinois, and are generally found in coal mines there. They have no real practical use, but are a favorite of mineral collectors because of their interesting aesthetics.

[Dmitry] received his pyrite disc from one such mineral collector in Boulder, CO, with the request that he use it for an interesting project. [Dmitry] himself specializes in art installations and unique instruments, and combined those passions in his pyrite disc sound object called Ra.

The concept itself is straightforward: spin the pyrite disc and use a laser to convert the surface striations into audio. But, as you can see in the photos and video, the execution was far from straightforward. From what we can gather, [Dimitry] used an Arduino Nano and a DIY laser pickup on a servo arm to scan the pyrite disc as it’s being spun by a stepper motor. That data is then sent to a Raspberry Pi where it’s synthesized (with various modulation and effects controls), to produce sound that is output through the single speaker attached to the object. Generating sound from unusual sources is certainly nothing new to regular readers, but the beauty of this part project is definitely something to be applauded.

Dimitry Morozov, better known as vtol, is a Russian musician, engineer and artist who decided that selfies were far too modern for his liking. Instead, he wanted people to wait for their gratification, and so hooked up an iSight camera to an Arduino-controlled Brother sx-4000 typewriter. Once a person sticks their face in front of the machine, named i/o, the typewriter painstakingly hammers out a portrait in ASCII art. The hardware was shown off at the 101 festival in Smolny, St. Petersburg in Russia, which ended earlier this month - but you can still see the device in action if you watch the video.
