// Induction balance metal detector // We run the CPU at 16MHz and the ADC clock at 1MHz. ADC resolution is reduced to 8 bits at this speed. // Timer 1 is used to divide the system clock by about 256 to produce a 62.5kHz square wave. // This is used to drive timer 0 and also to trigger ADC conversions.

In this instructable I will go thru all the steps to design and build a BFO metal detector. BFO (beat frequency oscillator) works by mixing two signals to produce an audible Beat frequency. One oscillator is fixed at a specific frequency, the second (of which the search coil is a part) varies it's frequency slightly in the precense of a metal.
