CIF Opening performance

On January 22, 2011, The Columbus Idea Foundry will hold its official reopening at its new location. Andrew Rahman, myself, and a few others are devising an audio performance for the event, utilizing both predetermined and live sonic properties that occur in a fabrication shop. The event will be recorded, then that recording transferred to a container housing an mp3 player. The sole function of the container is to play the audio event when accessed. 

On Wednesday Nov 24, Andrew and I had uninterrupted access to CIF for about four hours. We ran a bunch of power tools and hit all of the steel shelves with wood blocks. I'm not sure if Andrew recorded any of this, but I rolled a Tascam 488 with a Shure PG-81 to tracks 1-2.  Have to dump it down from cassette. 

The nonsense gave us two tangible pieces at days end. The first was an attachment to a drill that spins wooden blocks, the second was a thumb piano cut on the ShopBot.

More to come as this project unfolds.

The Living Room

We'll be relocating the official work space to a studio at The Colmbus Idea Foundry at the end of December. One noteworthy incomplete project at the apartmoshere involved wiring the living room up with force sensing and light dependent resistors into an Arduino.  

Person's proximity to the LDR's hidden in the bric-a-brac, and FSR's under the carpet resulted in the playing of an audio synthesis program through the living room stereo (pc free). After a month or more of repositioning hardware, trying to match pairs of LDR's using "assorment packs" of unknown resistor values, and startling the housemates, the system was removed.

first two pairs of potentiometers control a pitch and velocity each, and the fifth pot adds and subtracts. LED is from pin 13. the code is modifiable for chromatic and pentatonic mapping. 

this piece of hardware has stranded 22ga wire coming from the pots, but the prams for the board have solid copper.  the solder junctions were left uncoated for body contact points. 

this is proof of concept video. the victory is that it worked right off.

the enclosure is a hacked piece of electronic test equipment from Mendelson's Liquidation Outlet in Dayton, OH. http://www.meci.com/

it's best to go there in person. 

face plate is standard rack mount width, matching that Paia Vocoder kit tucked back in the arsenal. end product will be a plexi case for both, to be bussed together and used with external sound sources as well.
