Does anyone know where to find a good circuit diagram for detecting EMF? I contacted these guys (http://www.fashionvictims.org) about what circuit they are using, but they have have not responded with any information. Once a certain emf frequency is detected then it sets off my project... Anything like this out there? __________________________________ Do you Yahoo!? Protect your identity with Yahoo!
