Metal Detection Circuit Schematics I used an Arduino UNO to program a DIP ATMega328 I then removed the ATMega328 from the development board and embedded into a perfboard along with the rest of the circuit
Schematics | Beat Frequency Oscillator (BFO) Metal ,
The circuit shown must represent the limits of simplicity for a metal detector It uses a single HEF4093B quad two input Schmitt NAND IC and a search coil -- and of course a switch and batteri A lead from pin 4Y needs to be attached to a MW radio aerial, or should be wrapped around the radio If the radio has a BFO switch, switch this ON
BASIC CIRCUITRY Charles D Rakes METAL-DETECTING CIRCUITS II
This is basically how our single-transis-tor detector circuit operat In our single-transistor circuit, see Fig 1, only one RF oscillator circuit is used The other RF signal is supplied by one of many AM broadcast radio sta-tions A portable transistor AM radio receives the two RF signals and outputs an audible tone The mixing and audio amplification is handled by the transis-tor radio .
