    Simple Mobile Detector Circuit

    I tried to build your circuit for my science fair project. I started this in June. The science fair is tomorrow. I was a complete novice at electronics before I began this project (that was one of the reason why I did the project, to learn), so I did not know that your circuit diagram is incomplete and that I would need to build a complete different circuit to actually get it two work. You reference the complete circuit when you explain how it works, yet you don't show the whole circuit diagram??? You didn't even write the background information, but just copy and pasted. At least say where you got it from! If you are going to build this circuit, DO NOT FOLLOW THIS INSTRUCTABLE!!!!! Instead go to this website, http://www.electroschematics.com/1035/mobile-bug-detector-sniffer/. It has th...

Instead go to this website, http://www.electroschematics.com/1035/mobile-bug-detector-sniffer/. It has the complete circuit diagram. The chances of you getting this circuit to work ARE VERY LOW and even if it does work, it won't work very well. I have included photos of our failed PCB to show that I spent 4 months working on a project that was going to fail from the start.
