A Temperature Controlled DC Fan Circuit is like a smart fan controller. It uses a special sensor to feel the temperature around it. If things get too hot, the circuit kicks the DC fan into high gear, just like turning up the AC. But when things cool down, the fan slows down or even turns […]

Simple Induction Heater Circuit
This article explains how to construct a circuit that heats iron items using magnetism. We call this induction heating. WARNING: Creating circuits with high currents and voltages can prove harmful. Do this only under adult supervision and using the right safety equipment. For beginners this project is not advised. What is a Induction Heater Circuit: […]
500 Watt Induction Heater Circuit
This post is for 500 watt induction heater. Here the coil makes a strong magnetic field that changes very quickly. When anyone puts metal in the coil the metal heats up. This happens because of swirling currents in the metal called eddy currents. There is another effect from the metals properties that causes heating but […]
