In this article I have explained the basics of quadcopter body assembly using aluminum pipes and bolts, in the later sections of the article we will also discuss regarding a simple drone circuit which could be use for flying a small drone assembly without depending on complex microcontrollers. A quadcopter is perhaps the simplest flying […]

Simple 50 Watt Power Amplifier Circuit
A simple 50 watt amplifier circuit is I have explained below, I have explained how to build it at home using this versatile single amplifier chip LM3876T By: Dhrubajyoti Biswas UPDATE: For 40 watt amplifier circuits please visit this link. Analyzing the Circuit A good power amplifier is a necessity, especially when it comes to […]
Automatic Voltage Regulator (AVR) Circuit
An automatic voltage regulator circuit is quite well used where Voltage supply is only 120VAC. Many gadgets can operate good at 220V Ac that is why Voltage regulation is needed. By: Mehran Manzoor For this matter an appropriate voltage Regulator circuit is designed which can operate up to capacity of 1KW and gives Variable voltage […]
Push Button Fan Regulator Circuit with Display
A very interesting push button operated fan regulator circuit with LED display is explained in the following article, which can be built and installed at home for the suggested purpose. The idea was requested by Mr. Sriram KP. The Design Normally all fan regulators whether it’s a mechanical or electronic employ a rotary kind of […]
Simple Refrigerator Protector Circuit
This simple refrigerator protector circuit is actually a delay ON timer circuit which makes sure that whenever a power failure occurs or in case abrupt power fluctuations take place, the refrigerator is never allowed to switch ON instantly, rather after a delay of a few moments. Conventional Protection Features Today most modern refrigerators are equipped […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED […]
