The 25-watt audio amplifier circuit is powered by a tube circuit. The tube transistor (TR) will amplify the input to approximately 20 watts, while a dual transformer can increase the output to 40 watts. A wide voltage range of...
A post related to a do-it-yourself project for creating a VU meter and homemade rhythm lights that are easy to assemble. The project involves designing and constructing a visual audio level meter (VU meter) that responds to sound levels, as...
An efficient automatic solar garden lights circuit with minimal components. The advantage is that it operates entirely autonomously, with the solar panel functioning as a light detector. It switches the lamp off at dawn, charges the battery during the...
The LM 3909 LED flasher integrated circuit (IC) can be utilized to design various electronic projects. A circuit diagram illustrates the creation of a simple color organ using the LM3909 LED flasher IC. Three active filters process the audio...
This AC to DC power supply can output 5A in continuous operation and 12A peak current. This type of DC power supply uses a PCB, allowing for two case types for IC1: TO-220 or TO-3. The regulation of this...
The dual-channel circuit features the LM378 dual operational amplifier and operates with a supply voltage of 24V, supporting an 8-ohm load (or 16 ohms). Each channel delivers an output power of 4W. The circuit includes internal current limiting and...
