Low-power FM transmitter circuit diagram 1000M range

This circuit is designed to drive an ultrasonic transducer. A question has arisen regarding how to limit the output current, as a 60W transducer may be at risk of damage due to excessive current. Guidance or examples for integrating...

A circuit that utilizes one cycle of alternating current (AC) to produce direct current (DC). A half-wave rectifier circuit generates DC from either the positive or negative cycle of the AC input, but not both. It is important to...

This circuit is designed to control the mains pulse. The pulser's purpose is to switch the mains voltage on and off at intervals ranging from just under one second to a maximum of ten minutes. This functionality is beneficial...

A single-coil latching relay is utilized, which can latch and reset with opposite polarities. Testing of the circuit with dual opposite-biased LEDs showed no flickering in either direction, indicating stable charge and discharge behavior. However, there are concerns regarding...

This design circuit is for audio graphic equalizers, which are commonly found in commercial products, yet circuits for them are rarely published. The circuit features a simple design that requires an operational amplifier (op-amp) to amplify the input signal....

LED brightness control circuit: A simple circuit can be used to control the brightness level of an LED display. The LED brightness control circuit is designed to adjust the illumination level of an LED display according to user preferences or...
