Make this EMF Pump Circuit and Go Ghost Hunting

Last Updated on March 13, 2019 by Swagatam 32 Comments

EMF pump circuits are devices which are popularly used for the purpose of identifying paranormal activities or entities by generating rapidly rotating magnetic fluxes in the ether. The conventional devices use a spinning magnet fixed over a motor spindle, however these are mechanical types and are prone to wear and tear. Introduction The explained circuit […]

Cheap Semi Automatic, Tank Water Over Flow Controller Circuit

Last Updated on March 13, 2019 by Swagatam 75 Comments

simple water level controller circuit

The circuit presented here monitors the level of the water rising inside a tank and automatically switches OFF the pump motor as soon as the water level reaches the brim of the tank. The proposed tank water overflow controller circuit is a semi automatic device because it can only sense an overfill and switch OFF […]

Difference Between Alternating Current(AC) and Direct Current(DC)

Last Updated on January 31, 2019 by Swagatam Leave a Comment

sineDCwaveformdigaram

In this post we try to investigate the mains differences between alternating current (AC) and direct current (DC). The word AC and DC are pretty common with electronics and we all come across it while developing or dealing electronic circuit designs. Overview Though the terms are very ordinary with the field, many noobs become confused […]
