The infrared detector circuit can be easily wired on a small veroboard or any general-purpose printed circuit board. Pin configurations of IC LM386, transistor BC547 and melody generator UM66. LM386 ...

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 ...

Seiko Instruments Inc. announced the S-1910x series voltage detector with SENSE pin for automotive use that enhances reliability in voltage monitoring and CPU reset functions for safer system ...
