Build a Bat Detector | Nuts & Volts Magazine

The circuit diagram in Figure 2 shows the complete project and it really is as simple as it looks. Each of the four amplifiers in the quad op-amp IC is used as a building block, and these correspond quite closely with the functions shown in the block diagram. IC1/a and IC1/b comprise a two-stage, high gain microphone pre-amplifier.

ATtiny13 – PI metal detector – Łukasz Podkalicki

Presented metal detector uses PI method to generate a voltage spike in a search coil connected in parallel with capacitor. Next, ATtiny13 uses an Analog Comparator to measure a decay time to zero of resonant circuit. When a metal object nears the loop it will decrease time it takes for the pulse to decay to zero.
