For any electronic enthusiast making PCBs for an electronic project can be a lot of fun. A printed circuit board or PCB not only helps to build compact circuit projects, it also guarantees the working of the circuit fail proof and more accurate. In this post I will comprehensively explain a step wise process of […]
Newly Updated Circuit Projects:
How to Kill Coronavirus with Ozone Gas Generator
In this post I have explained the basic construction of an ozone generator apparatus for disinfecting a closed premise from dangerous viruses such as coronavirus. Ozone is a tested and an officially recommended method of eliminating viruses and pathogens on outside surfaces. Viruses Cannot be Killed with Medicines The fact that makes a typical influenza […]
How to Make a Solar Cell from a Transistor
The majority of newbie electronic hobbyists would certainly have a couple of burned up power transistors such as 2N3055 hiding inside their junk box. Supposing we have their internal semiconductor junctions still intact, the device could be transformed into a nice little solar cell by filing or sawing off the top cap of the device, […]
How Contactless Infrared Thermometers Work – How to Make One
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 […]
