In this post I will show how to construct a timer circuit for meditation practices which gives out beeping sound between 1 and 9 seconds (user selectable) and this beeping audio can be integrated with your mediation session, we will see how we can integrate the periodic beeping with “mindfulness meditation” as example in later […]
Newly Updated Circuit Projects:
Face Mask with UVC Disinfected Fresh Air
Face masks have so far proved to be the most effective first line of defense against all contagious epidemics and pandemics. However, the biggest discomfort with face masks is the difficulty in breathing and accessing fresh air. On the other hand, if the masks are made porous for letting fresh air in could also allowing […]
Using UV-C Light Chambers for Disinfecting Humans from Coronavirus
A rather easy way of disinfecting humans and objects on a large scale and in public places could be by irradiating them with ultraviolet rays (UV-C), in special UV-C illuminated chambers or passages. This includes the pandemic COVID-19, which can be suppressed by installing and implementing these specially created UV-C germicidal lamps. The following article […]
GSR Sensor Circuit for Biofeedback Measurements
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 […]
