This circuit can modulate a laser rate at frequencies of 50 kHz. We found the old documentation. The bipolar transistors can be the BD135 and 136 and the FET admits equivalent.
This intercom for the 27 MHz band was found in a recent English documentation, working with a...
This simple circuit allows you to control remote control servos that operate with pulses. The...
This circuit consists of a variation of the previous one being activated when the switch is...
