This circuit for controlling high power LEDs (up to 2A) is from a General Electric documentation from 1970. The circuit serves to modulate a transmitter in PWM. The circuit serves as a shield.
This setting appears elsewhere in this section. This was obtained from an American 1980s...
This speed control for small DC motors can operate from 6 to 12 V sources. The motors can drain...
We found this circuit in a 1964 Electronic Design. Transistors can be modern general-purpose...
