They are used for the safety of people to detect anyone carrying a metal arms etc.In this project we are going to design a simple metal detector circuit.There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 timer ic.
Ok as far as i can see everything looks ok i would use something like a irf740 on t2 r7 say 330 ohm and your coil 0.350uh the rest you will need a scope, i found without a scope you have bad results, i have built a few kits and it was hard without one c1 needs to be say 1000uf you want to keep the noise down best place to go would be geotech lots of info there and help.
