Hey everybody, I love this site... I've been looking online on how metal detectors work, it so far it seems fairly easy to make one. I think it just requres two coils of wire, a DC power source, some kind of DC->AC converter, a little speaker. I'm not exactly sure how this thing is put together, but if anyone knows, it would be really cool for a toy. | ||

I am planning on making a very simple metal detector. Here is my plan; I will have a circular coil of wire, and a smaller coil in the middle of the large one. The electricity would be applied to the large coil, and when the magnetic energy is bounced off of the metal object, it will be detected by the mini coil. The mini coil could be attached to a piezo-ekectric buzzer. | ||

Wow! Thanks for those sites Mr. Field. I have been searching for a while to find simple instructions for a metal detector, but many of the instructions were so expensive and time consuming, it would have been better to have just bought one. I guess I had the right idea in the design, but I guess there needed to be some beat frequency tuning. |
