This circuit, which can use the 4011 or 4001, was found in documentation from the 90s. The load depends on the transistor used, and the power supply must be isolated.
This circuit was found in documentation from the 80s. The components are from the time, but the...
We can make an oscillating relay producing a rectangular signal taking advantage of the inductance of...
The circuit shown in the figure is a voltage follower, that is, an amplifier with unit gain. The...
