In this post I have explained the basic working concept of thermal scanners or contactless IR thermometers, and also learn how to make a practical DIY prototype of the unit without Arduino. In the post COVID-19 era, witnessing doctors holding a contactless temperature gun and pointing toward the forehead of a COVID-19 suspect is a […]

How to Design MOSFET Power Amplifier Circuits – Parameters Explained
In this post I have explained various parameters that must be considered while designing a MOSFET power amplifier circuit. We also analyze the difference between bipolar junction transistors (BJT) and MOSFET characteristics and understand why MOSFETS are more suitable and efficient for power amplifier applications. Contributed by Daniel Schultz Overview When designing a power amplifier […]
How to Make Dye-Sensitized Solar Cell or Solar Cell from Fruit Tea
The innovation of dye-sensitized solar cells has expanded the device’s potential up to the point where it might completely oust costly silicon solar cells. In the following post I have explained how you can easily construct this versatile dye-sensitized solar cell using very ordinary materials. This experiment relies on the concept of utilizing the organic […]
How an Autotransformer Works – How to Make
An autotransformer is an electrical transformer which consists of only a single, continuous, non-isolated winding, with tapped terminals across various points of the winding. The winding section between the taps that correspond to the mains AC is applied with the mains AC supply, while the remaining taps are used for getting the desired output voltages, […]
LM3524 Datasheet, Pinout Function, How to Use
You may have heard a lot about the outstanding features of the IC LM3524 or the SG3524, however many of you may not be confident regarding how to set up the pinout functioning of these ICs? Or you may be wondering exactly how to use the IC for your specific needs and application designs? The […]
How to Use Diodes, Transistors, ICs as Temperature Sensors
Normally we find thermistors being used as the sensor for detecting and monitoring temperatures in electronic circuits. However, ordinary semiconductor components like transistors and diodes actually work better than thermitors when it comes to detecting temperature changes. In fact, this feature happens to be one of the greatest drawbacks of semiconductor devices, whose working characteristics […]
