Recycled Sound – An Art Installation Not Lacking Arduinos

[oakkar7] wrote in to show us [Ben Johansen] and [Jonathan Snow]‘s  interactive art installation, Recycled Sound(Website has a virus). The exhibit will premiere  in the TWU Arts Triangle Walking Tour March 25th from 5-7pm.

Currently a work in progress, the final plan is for the outdoor installation to feature a podium in the center with a rotating top, and various islands surrounding. As the podium’s top is rotated the surrounding islands come to life with a variety of light and sound displays which vary depending on how the podium is turned. While the electronics are not recycled, the actual sculptures and music making elements themselves consist of scrap yard parts and factory waste.

The whole display runs off of 12.. yes TWELVE Atmel 328s with Arduino boot loaders! The center podium houses a transmitting circuit consisting of two atmega 328s with Arduino boot loaders sharing a crystal, an hmc 6532 magnetometer breakout board and two RF transmitters.  The Islands each contain a receiving module with, obviously,  an Arduino and RF receiver. The receiving Arduinos connect to opto isolated switching modules for motors and lighting. Check out [Ben]‘s blog for in progress shots, code, and build information.

If you are looking to control some 12V motors/lights with your 5V Arduino be sure to check out the pictures in the blog. While we here at Hackaday may be quick to jump into soldering [Ben] follows the proper development progression to the letter. Each aspect is bread boarded, then refined, then transferred to a soldered perf board.

update: His site has some kind of malware going on. None of us noticed it in Firefox, but after complaints we fired up ol IE. Yup, nastyness there. You can go there at the following link if you dare.

DIY RF remote control


I was plotting one of my future projects and found this diy RF remote control. I was struck by how simple the circuits are thanks to the micro-controller and RF modules. This is an older write up, and I know you can get newer modules from Spark Fun electronics, but when I was younger, RF controls always seemed to be the black magic of diy electronics.
