Natural Mosquito Repellent Using High Watt Resistor
As the name suggests, to build this simple natural mosquito repellent circuit you will just require a high watt resistor, a few drops of lemon eucalyptus oil and mains supply input. Chemical Based Mosquito Repellent are Harmful for Health You might be already familiar with these popular ready made mosquito repellent units which come in […]
Simple SG3525 Sine Wave Inverter Circuit Explained
In this post we will discuss two methods of designing pure sine wave inverter circuits using 555 IC based SPWM processing. In the first concept we connect the 555 processors directly with the SG3525 outputs and do the sine wave conversion directly at the MOSFET gates. In the second concept we do it externally and […]
Transistor Zener Diode Circuit for Handling High Current Stabilization
The high power “zener diode” circuit using transistor shunt regulator presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. Normal Zener Limitation The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot […]
High Voltage Battery Charger Circuit
In this post I have explained a simple automatic High Voltage Battery Charger Circuit which can be used for an automatic charging control of any preferred high voltage battery bank such as a 360V battery bank. The idea was requested by “resonance”. Circuit Objectives and Requirements Circuit Diagram The Design The figure above shows a […]
How to Design High-Pass and Low-Pass Filter Circuits Quickly
In this post I have explained how to design audio filter circuits such as high pass filter and low pass filter circuits effortlessly without going through the hassles of complex simulation and calculations. The presented designs will enable creating filter circuits only for the desired specific frequency bands and block all other unwanted frequencies. What’s […]
