Metal Detector Pulse Motor
This is a pulse motor that is driven by a simple metal detector ‘kit’ found online from many locations. Grandad actually made this project happen by posting a great assembly video on this metal detector ‘kit’. The device is tricky to solder up unless you have the right tool, solder, and a tutorial video. Thanks Grandad.
Here is his excellent video on this metal detector ‘kit’.:
The motor will work without the buzzer in the circuit and runs from 3v to 5v at about 30mA draw.
