This circuit was found in Radio Electronics from the 90s. The components used are common, and the transistors and CIs must be equipped with heat sinks.
The circuit in the figure uses two operational amplifiers: an LM101A and an LM102. Diodes admit...
This simple circuit can use any general-purpose transistor. The power supply must be isolated. The circuit...
Up to 0.5 A DC motors can be controlled by this circuit. Direction change is achieved by a logic...
