Ferrite Core Material Selection Guide for SMPS
In this post I have explained how to select ferrite core material with the correct specifications for ensuring proper compatibility with a given SMPS circuit design Why Ferrite Core Ferrite is a wonderful core substance for transformers, inverters and inductors in the frequency spectrum 20 kHz to 3 MHz, owing to the benefits of reduced […]
Mosquito Killer Circuit with Window Trap
In this post I have explained a simple mosquito electrocution net, or mesh circuit which can be easily built and installed on a home window for blocking and killing an in-surge of mosquitoes. The idea was requested by Mr. Ram. Technical Specifications Please help with any working circuit diagram for Mosquito, Insect Killer using Walton […]
How Mosquito Traps Work
Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very […]
Adjustable CDI Spark Advance/Retard Circuit
In this post we’ll learn about a simple circuit which allows a manual adjust feature for the spark timing of a motorcycle’s CDI either to achieve an advance ignition, retarded ignition or simply a normal timed ignitions. After a comprehensive study regarding the subject I was apparently successful in designing this circuit which can be […]
Remote Controlled Trolley Circuit without Microcontroller
In this post I have explained how to make a cheap yet powerful remote controlled trolley which can be maneuvered left, right, forward and reverse as required, by the user using the given remote handset. The idea does not rely on an microcontroller circuit. In one of my previous posts I discussed about a simple […]
