LED high power modulator

PWM rectifier power controller power supply. Visit the page to read the explanation about the associated circuit diagram. A PWM (Pulse Width Modulation) rectifier power controller is a sophisticated electronic circuit designed to convert alternating current (AC) to direct current...

This small transmitter can reach distances of more than 1 km under favorable transmission conditions. Modulation can be achieved using a microphone, such as an electret microphone, or another audio source. The transmitter includes a coil made of 5...

A PoE Plus power level of 30 W can be achieved by utilizing an external MOSFET along with a controller that is compatible with the older standard. Power over Ethernet (PoE) technology enables the delivery of electrical power along with...

The circuit utilizes a Pt100 type resistance temperature detector (RTD). It operates within a temperature range of 100 to 600 °C, where the XTR105 outputs a current of 4 to 20 mA, and the RCV420 provides an output voltage...

The most challenging aspect of the build was to find or design a circuit capable of handling the load while remaining within budget. This circuit achieves both objectives. It adjusts the power output using a potentiometer (variable resistor) R1,...

This circuit is a Phase-Locked Loop (PLL) system designed to function as an FM demodulator. The output of the Voltage-Controlled Oscillator (VCO) tracks the FM signal, and since the input voltage of the VCO is proportional to its output...
