In this article I will show how to construct an interesting project, which could potentially enhance your brain’s capability. I have explained how to make a TDCS brain stimulator circuit. Overview This may sound like science fiction, where an evil scientist connects his head to some complex machine and gaining super human capabilities. This may […]
3-Step Automatic Fast Battery Charger/Controller Circuit
Generally it is noticed that while charging batteries people hardly pay any special attention toward the procedures. For them charging a battery is simply connecting any DC supply with matching voltage with the battery terminals. A fast battery charger circuit charges a battery with enhanced speed so that it is charged in less time than the specified period. […]
Ultraviolet (UV) Sanitizer Circuit for Disinfecting Home Materials
In this post I have explained the making of a simple, cheap yet effective ultraviolet or UV-C home sanitizer circuit using ultra violet rays or UV-C. The idea was requested by Mr. Shah (kristin). Using UV Rays against Coronavirus The UV-C sanitizer circuit I have explained below can be effectively applied for sanitizing all external […]
How to Generate Pure Oxygen and Hydrogen at Home
In this article I have explained a simple method through which large amounts of oxygen and hydrogen could be generated at home using an ordinary electrical setup, and very cheaply. Before I have explained the actual process, it would be important to read the following points related to the experiment: Warning: The simple concept of […]
Room Air Ionizer Circuit – For Pollution Free Living
In this article I have explained how to build a simple room ionizer circuit for getting a clean, pollution free environment right inside our home. Introduction Have you ever thought or wondered why atmosphere over hill stations and other similar places which are far away from modern cities give you a feeling of freshness and good health? […]
