The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor ...

The heart of this diy metal detector circuit is the CS209A IC. The metal detector is built with one 100µH coil that has 40 mm in diameter and is made of 50 turns/0.4 mm wire. CS209A has one oscillator ...

This allows these devices to find an alternative usage in a simple analog zero-crossing detector circuit. This circuit ... receiver channels do not switch at exactly 0.00 V. With a typical DS3486 ...

In recent times there has been remarkable progress in the development of silicon-based photonic circuit components such as on-chip sources, manipulators, detectors, storage, filtering and ...
