In this post I have explained how to build a very simple GSR sensor circuit using just a couple of transistors and a few other passive components. A GSR (Galvanic Skin Resistance) sensor, also known as a skin conductance or electrodermal activity sensor, measures the electrical conductance of the skin, which changes in response to […]

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 […]
Transcutaneous Nerve Stimulator Circuit
Transcutaneous electrical nerve stimulation (TENS) is a term typically referred to the use of nonpharmacologic or noninvasive kind of treatment for neutralizing superficial pains. How Transcutaneous electrical nerve stimulation Works Researches have shown that TENs helps to control pain both over peripheral and also central mechanisms.The central mechanisms include areas of spinal cord and brainstem that […]
Hospital Room Call Bell Circuit for Alerting Nurse with a Button Press
In this post I have explained a simple hospital room call bell circuit which can be installed in hospital patient rooms for allowing the patients to get a quick access to a medical representative or a nurse whenever in need, by simply pressing a call button at the bedside. The idea was requested by Mr. […]
Automatic Hand Sanitizer Circuit – Fully Contactless
In this article I have explained how to make a low cost yet fully automatic hand sanitizer dispenser circuit which will allow a touch-free or contactless dispensing of the sanitizing liquid on the user’s hands. This contactless hand sanitizer circuit facilitates the user to access the sanitizing liquid on hands automatically without the need of […]
Blood Electrification Circuit: Explanation And Working Principle
Here we are talking about one circuit which many people know by the name Blood Electrification Unit, and this circuit became known because of Bob Beck many years back in the 1990s time, so now people also call it Beck Blood Electrifier. This unit is nothing complicated looking but the idea sounds heavy because it […]
