An electronic incubator thermostat circuit shown in this article is not only simple to build but is also easy to set and acquire exact tripping points at various different set temperature levels. The setting may be completed through two discrete variable resistors. How Incubators Work An Incubator is a system where bird/reptile eggs are hatched […]

Controlling your door lock through your personal cell phone was never this easy. Learn how to build a simple electronic circuit that will help in converting your ordinary door lock into a high security door lock which can be now controlled through your own cell phone. Your ordinary door lock can be now very easily […]
2-Stage Mains AC Voltage Stabilizer Circuit
In this article I have explained how to make a 2 relay or two stage mains AC voltage stabilizer circuit for controlling and regulating 220V or 120V mains voltages through a simple circuit. Introduction In this power stabilizer circuit, one relay is wired to select the high or the low tap from the stabilizer transformer […]
5 Interesting Flip Flop Circuits – Load ON/OFF with Push-Button
Five simple yet effective electronic toggle flip flop switch circuits can be built around the IC 4017, IC 4093, and IC 4013. We will see how these can be implemented for switching a relay alternately ON OFF by alternately pressing a single push-button or through touch pads, which in turn will switch an electronic load […]
SCR/Triac Controlled Automatic Voltage Stabilizer Circuit
In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]
