Is this Inductive Overunity? Maybe Not

Last Updated on May 20, 2026 by Swagatam

free energy

While experimenting with a 300V DC to 220V AC inverter circuit, I noticed a strange overunity phenomenon which appeared to be like the generation of free energy from the inverter transformer. Recently while experimenting with a high voltage converter circuit, I was quite astonished to see a strange overunity kind of occurrence wherein the inverter […]

Making a Float Switch Circuit for a Corrosion-free Water Level Control

Last Updated on December 31, 2019 by Swagatam 15 Comments

float switch assembly design

A float switch is a device which detects a fluid level (such as water) and activates a set of contacts which may be further integrated to a control circuit for restricting the fluid flow behavior. Why a Float Switch The advantage of a float switch is that it works without a direct contact with the […]
