In this video i am showing, how to make a single transistor low efficiency D718 amplifier heavy bass with heavy bass controller. I used here a 50k pot with a pair of 104 ceramic capacitors as low pass filter for subtracting the high frequency. I am using here 12 volts / 5 amps PC power […]
Demonstrating here, how to make an extremely powerful stereo LA4440 bass amplifier DIY Homemade. I have assembled this circuit on a high-quality PCB which was ordered from JLCPCB. Stereo amplifier history dates back to the 1950s when there was a huge surge in living room hi-fi systems. These amplifiers offered users increased sound fidelity and […]
In the following video, I am showing how you can make a powerful DIY homemade D718 amplifier using four D718 NPN transistors. This is a class-A amplifier with low efficiency. I am just demonstrating it for educational purpose. Its design is with minimum components for beginners or students. We do not recommend it for continuous […]
This post is being created for Circuit diagram of amplifier. Below is the list of circuit diagrams of mono and stereo amplifiers, bass and treble used in all amplifier project videos of this website. All the headings of each circuit diagram is designed clickable to watch the related project videos. All the circuit diagrams are […]
I am showing here, how can you find a charge protection module for the 18650 battery bank for free. Make a Battery Bank for mobile charging or use it for LED Emergency Light. Lithium cells are the most common and easily available in the local market. Also, you can remove them from any scrap or […]
In this video i am showing, how to make a 13003 amplifier DIY homemade using two 13003 transistors from an old and damaged CFL bulb. I demonstrated it with 3.7 volts 18650 lithium cell. You can increase the voltage to get more power. I used here two 5 inch 4 ohms speakers which is providing […]
In this video i am showing, how to make a very simple but powerful bass audio DIY D718 stereo amplifier homemade using two D718 transistors. This is a class-A amplifier with low efficiency. I am just demonstrating it for educational purpose. It is designed with minimum components for beginners or students. I do not recommend […]
This device was invented by Nikola Tesla and is a great demonstration experiment. I demonstrated in this video, how to make your own a very simple mini tesla coil diy at home using minimum components. So, you can easily make this tesla coil at home. Therefore, I hope you will make it without any problems […]
Homemade mini wind turbine diy for school students and Teachers. This demonstration video uses simple components and is intended to be used for a school science project. Components used are pvc pipe & fittings, plastic bottle & styrofoam (thermocool). List of items which we used in this project is listed at the end of this article.
