Making a Thermoelectric Generator (TEG) Circuit

A thermoelectric generator (TEG) is a kind of “free energy device” which has the property of converting temperature into electricity. In this post we learn a little about this concept and find out how we can use it to generate electricity from heat and cold. What’s TEG In one of my earlier articles I have … Read moreMaking a Thermoelectric Generator (TEG) Circuit

Fish Aquarium Oxygen Generator Circuit

In this article we discuss how to make a simple fish aquarium oxygen generator circuit using the concept of electrolysis of water. Generating Pure Oxygen The production of oxygen through electrolysis can be expected to supply a pure and a bigger quantity of oxygen compared to the usual pumped air concept which injects only only … Read moreFish Aquarium Oxygen Generator Circuit
