Neighborhood Public Radio is an independent, artist-run radio project committed to providing an alternative media platform for artists, activists, musicians, and community members. NPR (founded in 2004 Oakland, California) who shares their moniker with National Public Radio, streams onto the Internet as well as utilizing their own low-power FM transmitters. The group organizes community-based projects that are free and open to the public. By circumventing the need for commercial or corporate sponsorship, NPR provides a genuine conduit for free speech through grassroots low budget shows based on providing “snapshots” of various people and neighborhoods.
“If it's in the neighborhood and it makes noise, we hope to put it on the air.”
Neighborhood Public Radio have broadcast from, done shows or presented their work at The Whitney Museum of America Art as part of the Whitney Biennial 2008, Artists Television Access, Southern Exposure, San Francisco; Novi Sad Contemporary Museum, Serbia; Fadaiat//Borderline Academy, Tarifa; Chicago's Version 5, Yerba Buena center for the Arts, San Francisco; FSK Radio in Hamburg, and the De Young Museum, San Francisco. Creative Work Fund, Walter and Elise Haas Fund, CEC Artslink, and ISEA Community Domain Commission have supported NPR.
Sound Studio of Chicago ( www.exsost.org ) will be held the first
ever Experimental Garage Sale. The event will feature an open air
flea market/swap meet in the beautiful backyard of the Studio.
The items available for purchase or trade will consist mainly of
gobs and gobs of toys and parts suitable for circuit bending
as well as completed circuit bent musical instruments.

Here is the schematic for the 3rd revision of my vactrolSynth. It uses only one 4093 quad NAND gate chip. Try experimenting with different capacitor values for the control and audio oscillators to achieve various tonal capabilities. Note: this schematic omits a potentiometer before the vactrol LED... add this for a pseudo pitch control. Try to use a super-bright LED and a photo-resistor with a wide range for excellent frequency response.
I successfully repaired my CS-5 last night. I was a bit of a struggle because the previous owner attempted the same thing but destroyed the circuit board contacts in the process... I had to do a bit of surgery but it's quite solid now.
For anyone who would like to know: in order to remove the front panel, you need to take off the two plastic ends and then the 3 screws along the bottom in the back. The top should then be free of the body.
