This circuit for controlling a model of an elevator via wire was found in the December 1997 issue of Electronics Now magazine. DC motors must be rated at the voltage of the transformers.
This circuit, which can act as a shield, was found in a 1969 documentation. The circuit uses...
This oscillator can generate signals from 100 kHz to more than 50 MHz depending on the crystal used...
This simple multivibrator circuit generates a 1 kHz signal rich in harmonics. The circuit is from...
