Hacking for GIs




Here’s a simple project that might be interesting to try out. This simple circuit can detect the invisible fields of voltage which surround all electrified objects. It acts as an electronic “electroscope.” Regular foil-leaf electroscopes deal with electrostatic potentials in the range of many hundreds or thousands of volts. This device can detect one volt. Its sensitivity is ridiculously high.
MacMinute has a story about Trent Reznor of Nine Inch Nails making the band’s new single, “The Hand That Feeds” available to download for Mac users with GarageBand to mix and mash up (an actual multi-track audio session). “For quite some time I’ve been interested in the idea of allowing you the ability to tinker around with my tracks — to create remixes, experiment, embellish or destroy what’s there,” Reznor says. Here’s a screenshot of it on my Mac (View image) and here’s where to get it (70MB file). Here are a couple of the first remixes!
