This circuit was found in a Hands On Electronics from the 90s. It is intended to supply old tape players to batteries with a voltage of 7.5 V from the 12 V of a car battery or source.
The pass-through alarm we present uses an infrared (IR) emitter as a sensor. When cutting the...
In this circuit, the output voltage is slowly established, thus avoiding the impact when...
This is the minimum amplifier configuration with the LM380 and can provide an output of up to 2.5...
