Listen to the hypnotic sound of a red crystal


Red is an optic-sound electronic object that uses simple light sources and optical elements to create audiovisual performance. The machine was named as a color because at the center of the work there is a red glass crystal and a flexible Fresnel lens. Dmitry Morozov aka :: vtol: : created it using Arduino with pure data and python scripts:

The project includes many reworked electronic devices – a CD-rom, an old scanner, reused electric motors. Multiple moving elements provide wide variability for rather primitive optical elements. It is accomplished by constant change of focal length between the light source, crystal and lens, as well as by changing the crystal’s tilt angle and mechanical distortion of the lens. The object works autonomously, by algorithm with many accidental events tied to feedback, with sensors defining the position of various mechanical elements in relation to the range of their movement. The sound part has up to 4 voices which depend on the activity of various elements. The sound is also in direct interaction with actual position of those elements, and basically is voicing the process of movement, brightness of light, and intensity of the piece.

Watch how it works in this hypnotic video:

Colorful Fan and LED Controller for 3D Printer

[Dave] just couldn’t take the ambient noise from his Lulzbot Mini anymore, so he built a fancy fan controller for it.

He measured some points on the printer’s Rambo controller board to see what actually got hot during a print. The hottest components were the motor drivers, so he taped a thermistor to them. He also placed one in the printer’s power supply. He replaced the main fan with a low noise model from Noctua (which have the most insanely fancy packaging you could imagine for a computer fan). The software on an Arduino Nano now idles the fan at an inaudible 650RPM, if an unacceptable temperature increase is detected, it increases the fan speed for a period, keeping everything nice and quietly cool.

The graphics display was added because, “why not?” A classic reason. The graphics runs on a hacked version of Adafruit’s library. It took him quite a while to get the graphics coded, but they add that extra bit of high-tech flair to keep the cool factor of the 3d printer up before they become as ubiquitous as toasters in the home. The code, fritzing board layout, 3D models, and a full build log is available at his site.

This Week in Making: Marble Machines, Filament Tips, and More

This past week we celebrate Arduino Day with Makers like, saw a new marble machine, and started a conversation about how coding is taught.

Brazillian Class Creates Digital Board Game

A class in Brazil was given the assignment to make a board game. [Marcelo], presumably, heard his son lamenting how lame it was going to be if the board was just cardboard with some drawings on, and came to the rescue.

A match meant to be.

Working with the class, they came up with the rules of the game. We’re not certain what those are, but it involves a regular game board, a flashing light circle with numbers, and a fusion between Operation and one of those disease transmitters commonly found at the doctor’s office. You can try to puzzle them out from the video after the break.

The brains of the board is an Arduino with an external EEPROM for all the sound effects and other data needed for this construction. Everything is laid out on a beautifully done home etched PCB. It’s too bad the other side of the board isn’t visible.

We’re sure the kids learned a lot working with [Marcelo]. It would have been nice if a traveling wizard came to some of our earlier classes in school and showed us just how much cool stuff you can do if you know electronics.

The Most Immersive Pinball Machine: Project Supernova

Over at [Truthlabs], a 30 year old pinball machine was diagnosed with a major flaw in its game design: It could only entertain one person at a time. [Dan] and his colleagues set out to change this, transforming the ol’ pinball legend “Firepower” into a spectacular, immersive gaming experience worthy of the 21st century.

A major limitation they wanted to overcome was screen size. A projector mounted to the ceiling should turn the entire wall behind the machine into a massive 15-foot playfield for anyone in the room to enjoy.

 

With so much space to fill, the team assembled a visual concept tailored to blend seamlessly with the original storyline of the arcade classic, studying the machine’s artwork and digging deep into the sci-fi archives. They then translated their ideas into 3D graphics utilizing Cinema4D and WebGL along with the usual designer’s toolbox. Lasers and explosions were added, ready to be triggered by game interactions on the machine.

To hook the augmentation into the pinball machine’s own game progress, they elaborated an elegant solution, incorporating OpenCV and OCR, to read all five of the machine’s 7 segment displays from a single webcam. An Arduino inside the machine taps into the numerous mechanical switches and indicator lamps, keeping a Node.js server updated about pressed buttons, hits, the “Lange Change” and plunged balls.

The result is the impressive demonstration of both passion and skill you can see in the video below. We really like the custom shader effects. How could we ever play pinball without them?

Control Robots to Solve Puzzles in This Twitch-Style Robot Livestream

Robotics is a booming field that gets everyone excited, but when the talk comes to real life applications the response is a bit more tepid. Pundits tend to point to the “3 D’s”—dangerous, dirty and dull—but they often overlook a market with short term payoff: Entertainment. We are beginning to see some […]

Explore relations between nations daily with News Globus


News Globus is an unusual physical interface that piques the curiosity of people and asks them to explore the world by the news putting in relation  places of the world. It was designed by Bjorn Karmann, Charlie Gedeon, Mikio Kiura, Sena Partal wiring 20 regions to a Genuino board inside the sphere. When two regions are connected with the jack, the Genuino selects a country randomly from each region and queries the NY Times API for news containing both locations. A web server then selects a story and converts the headline and byline to a mp3 file which is played either from the headphone jack or the speaker at the  base of the globe:

The shape of the globe is an interesting artifact from the past which was combined with modern technologies and online services. Instead of allowing people to hear the news of one place, the audio jacks bring to mind the metaphor of the phone operator to get people to discover surprising connections between places near and far from each other.

Check the video to see it working:

The project was developed during the Interaction Design Programme at CIID with the help of Massimo Banzi and Dario Buzzini.
