This bidirectional motor control was found in an 80's Electronic Engineering. The circuit uses a component of the time and is suitable for motors up to 1 A.
This high-gain circuit uses junction FETs (JFETs) and must be powered by somewhat high voltages. The...
This circuit counts 1 per second, displaying the value in binary. The circuit is TTL and must be...
Critical components of this project are the Geiger tube and the 300V battery. The battery can be...
