this is a small metall detector built based on the bc547 transistor, it uses a electro magnitic coil to detect fulctuations caused by metal and amplifies the signal into a led and buzzer. It runs on a nine volt battery, has a buzzer and led.

I got the pcb, components and soldered it all after refering to a few wiring diagrams. There is a potentiometer on the pcb to change the cutoff fluctuation limit.
