Hello Firends, W elcome  to Electronics Tube Blogspot. In this blog I will be sharing an amazing circuit diagram for flashing high power LEDs. The circuit is very easy to be assembled on a PCB.  It employs only a few components. This circuit was tested on breadboard. The recommended power supply for the circuit is 12 volts 2A. The power supply can be adjusted as per the power spec of the LED used in the circuit. Concept of the LED FLASHER Circuit The LED used in this circuit is of 12v/20watts. The switching action of the LED is obtained using popular IRFZ44N MOSFET. Any similar mosfet can be used in the circuit. The heart of the circuit is the astable-multivibrator built using NE555 timer chip.  The 100K Potentiometer can be tuned to obtain different time intervals for ON/OFF. Spares needed for LED FLASHER Circuit : LED : 10 to 40 Watts  Resistor : 10K Potentiometer : 100K MOSFET : IRFZ44N or IRF540N (Any similar MOSFET) IC : NE555 Capacitors :

Hello  Friends, Welcome to  Electronics Tube Blog-spot, In this blog I will be sharing you an amazing circuit diagram for a power-full sub-woofer for indoor use.The circuit is very easy and cheap to be assembled. This circuit was built and tested by me on a 12” Subwoofer. The bass quality was awesome . The circuit is cheap to be assembled as it is powered using single supply. The components used in this circuit are low priced as well easily available around the market. This circuit can be also used for car sub-woofers if built in two channel mode. Each would have output power of around 50 Watts. About the Circuit Diagram for 50 Watts Amplifier The filter of the circuit is built around popular LM358 Dual op-amp. The audio input can be directly fed to the input of filter stage . The output of the LM358 drives the power amplifier stage which is built using TDA 2030 audio chip along with MJE3055 and MJE2955 ( Complementary Transistors    Pd = 75-Watts ). The circuit is pow
