Ridiculously sensitive charge detector
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.


We’re going to try an experiment with an additional audio program starting next week. We’re still gearing up to release our interview series really soon with great audio from all sorts of amazing Makers out there. But, we’ve had a ton of requests to do a weekly show with DIY projects, hacks and commentary on stuff we’re up to at MAKE, so we’re going to do it, why not. We’ve also been doing the FM radio rounds lately and the “call in” part of the shows have been packed with hundreds of folks working on cool projects or looking for advice- so if you’d like to ask us a question or tell us what you’re up to call 206-888-MAKE. Toll charges apply, we’ll have a Skype voicemail set up soon too, but do call in or post up questions here!
As some of you noticed I was offline for a couple days this week, at the peak of depression (wireless deprivation) I considered grabbing a EVDO card, but since I use a Mac for some of my work, the card I was considering didn’t seem supported. No longer! The folks over on EVDOinfo.com have
A lot of MAKE blog readers requested an easy way to suggest a site, so we made a
