The following circuit was requested by one of the readers of this blog Mr. Keval. The actual request was for a rain triggered windshield wiper circuit, but the idea here has been further enhanced with a quick start feature for better efficiency. How Conventional Wiper Systems Work Normally, electronic wiper control circuit involve a bistable for switching the […]

2 Easy Automatic Inverter/Mains AC Changeover Circuits
I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains is present and vice versa. And also the system must enable automatic switching of the battery charger such that when AC mains is present the […]
How to Generate Pure Oxygen and Hydrogen at Home
In this article I have explained a simple method through which large amounts of oxygen and hydrogen could be generated at home using an ordinary electrical setup, and very cheaply. Before I have explained the actual process, it would be important to read the following points related to the experiment: Warning: The simple concept of […]
IC TDA 7560 Datasheet – 4 x 45W QUAD BRIDGE CAR RADIO AMPLIFIER PLUS HSD
In this post I have explained the datasheet of the IC TDA7560 which is a cutting-edge BCD (Bipolar / CMOS / DMOS) technology class AB 4 x 45 quad Audio Power Amplifier in Flexiwatt 25 package made for super high power car radio. The thoroughly interdependent P-Channel/N-Channel output composition makes it possible for a rail to rail […]
How to Replace a Transistor (BJT) with a MOSFET
In this post I have explained the method of correctly replacing a BJT with a MOSFET, without affecting the final outcome of the circuit. Introduction Until MOSFETs arrived in the field of electronics, transistors or BJTs to be precise ruled the power switching circuits and applications. Though even Bipolar Junction Transistors (BJTs) can not be […]
Low Battery and Overload Protection Circuit for Inverters
A very simple low battery cut-off and overload protection circuit has been explained here. The figure shows a very simple circuit set up which performs the function of an overload sensor and also as an under voltage detector. In both the cases the circuit trips the relay for protecting the output under the above conditions. […]
