Today our houses are configured with electrical and electronic systems which have made our life much easier and convenient.
These systems are extremely advanced and are designed to execute a set of sophisticated applications in order to make our homes safer and enhanced with added facilities and comfort.
The list of articles that are explained below demonstrate a handful of circuit designs which can be built by any new hobbyist and installed in their homes for getting the specified protection and luxury.
The compilation of circuits included below mostly discuss protection related concepts intended to make our home electrically shielded from voltage hazards, from manual thefts, and from harsh changes in climatic conditions.
For example here we have articles on automatic voltage cut off systems to protect our house electrical from short circuits, or overloads, we also have ELCB designs which ensure no leakage current flow from the earthing wires, and sensor based electrical installations which provide protection against thefts and house breaks, we furthermore have articles on air purifiers, home temperature monitors etc
This circuit is designed to sense the whistles from a pressure cooker and count the number over a digital display. The system relieves the user from the stress of constantly monitoring the cooker and from manually counting the whistles. The idea was requested by Mr. P.K. Bajpai Design Concept In many of the Asian countries … Read morePressure Cooker Whistle Counter Circuit

In this article we discuss an easy to build a 7 stage high wattage in the order of 5000 to 1000 watts stabilizer circuit which can be used for controlling our mains AC line fluctuations and for producing very accurate stabilized voltage outputs for our domestic electrical appliances. Circuit Operation The proposed Accurate 7 relay OpAmp Controlled Mains … Read more5 KVA to 10 KVA Automatic Voltage Stabilizer – 220 Volts, 120 Volts
We all use remote control handsets for controlling various household devices such as TV, AC, Music systems, curtains etc, and sometimes we seem to have problems with these devices, or even a newly purchased remote controller unit occasionally seem to malfunction, and identifying the issue becomes quite difficult for us. This simple 2 transistor circuit … Read moreTV Remote Control Tester Circuit
In this article we learn how to design and build a solid state contactor circuit using triacs for operating heavy duty loads like submersible borewell pump motors with high reliability, and without any concerns about wear and tear issue or long term degradation issues of the contactor unit. What is a Contactor A contactor is … Read moreSolid State Contactor Circuit for Motor Pumps
This simple homemade mosquito swatter bat neither requires a circuit nor a battery for the operation. The entire design works using a single high voltage capacitor and through quick charging from mains AC socket. (Designed by me) Introduction In a few of my earlier posts I have discussed how to make mosquito zappers using the … Read moreBuild this Mosquito Bat without Battery
