colorvisualizer

“The color Visualizer” is an immersive installation to understand how color is used in nature to communicate between living organisms and to explore biodiversity through the lens of color:

By plucking an array of multi-colored strings, which are layered over the large array of high resolution screens, visitors can explore over 100 unique color stories as vibrant images and short videos appear before them. Strum a red cord, for example, and learn how a male cardinal bird colors his vibrant red feathers with pigments from food; strum a yellow cord and see how a yellow leopard’s spotted coat allows this predator to blend in with shadow and light while moving through tall grass.

The eye-catching cylindrical installation is part of the permanent exhibition “The color of Life” that opened in June 2015 and was created by Tellart in collaboration with the California Academy of Sciences. It was prototyped using Arduino Uno and it’s currently shortlisted for the Interaction Awards, representing excellence in interaction design.

In the video below the team working at the project explain the main features of the educational installation and show a bit of the making of:

torch1Tiki torches are a fun summer lighting solution and this RGB LED version, that uses an Arduino, can be a great alternative to an open flame.

Arduino Powered Digital Kaleidoscope

kaleidoscope

[Jose's] latest project brings an old visual effect toy up to date with digital electronics. Most of us are familiar with inexpensive kaleidoscope toys. Some of us have even built cheap versions of them with paper tubes, mirrors, and beads. [Jose] wanted to try to recreate the colorful pattern effects created by a kaleidoscope using an Arduino and an addressable LED strip.

The build is actually pretty simple. The base is a disc of PVC cut to just a few inches in diameter. [Jose] started with an addressable LED strip containing 60 LEDs. He then cut it into 12 sections, each containing five LEDs. The smaller strips were then mounted to the disc, similar to spokes on a bicycle wheel. The LED strip already has an adhesive backing, so that part was trivial.

The final step was to add some kind of diffuser screen. The LED strips on their own are not all that interesting. The diffuser allows the light to blend together, forming interesting patterns that are more reminiscent of the patterns you might see in a real kaleidoscope. Without the diffuser you would just see individual points of light, rather than blended color patterns.

The whole thing is controlled by a small Arduino. [Jose] has made the code available at the bottom of his blog post. Be sure to watch the video of the system in action below.

Teach kids how colors are made with the color machine

color machine

The Color Machine (La macchina dei colori, in Italian language) is a tool to teach children about the use and the operation of RGB color coding, which is used in all digital devices (TVs, smartphones, computers, etc.). It was created with Arduino Mega by an italian duo composed by Fabio Ghidini and Stefano Guerrini:

Using 3 knobs you can increase the percentages of red, green and blue separately, and the LED strip at the top of the machine lights up consistently with the color mix choosen.

The Color Machine has 4 different operating modes: “let’s create colors”, “guess the color”, “the names of the colors” and “demo”. Under the guidance of a teacher, children can play and learn at the same time to recreate colors with additive synthesis. This device is currently used in the educational workshops of Musil – Museum of Industry and Labour of Rodengo Saiano (Italy).
