Make this Soft-Start Power Supply for Amplifier Loudspeakers
The purpose of the suggested slow-start power supply circuit is to prevent the loudspeaker which is hooked up to the amplifier from producing an unpleasant and loud “thump” sound when […]
Dry Run Protector Circuits using Transistors only
The basic dry run protection circuits using BJTs shown here provide simple ways to check for low water levels in an underground tank but without needing to use probes inside […]
IC 555 Dry Run Protection Circuit
An preexisting circuit for an IC 555-based water level controller may be modified to include the dry run protection, as seen below: In the schematic above, the dry run function […]
