Thunder Lightning Detector Circuit – LED Blinking in Response to Thunder
This simple circuit will enable you to visualize distant thunder lightning through a correspondingly choreographed LED flashes, exactly in accordance with the lightning that may be taking place somewhere in the distant sky, the response will be simultaneous and thus much prior to the sound that may reach your ears after a few seconds. RF […]
Connecting Voltage Regulators 78XX in Parallel for High Current
In this post we investigate how to connect popular voltage regulator ICs such as 7812, 7805 in parallel for acquiring high current output from the ICs. Voltage regulator chips mostly have their maximum current output specs fixed to some predetermined levels. Increasing them to a higher level would normally call for external out board transistors […]
How to Design an Induction Heater Circuit
In this article I have explained a step by step tutorial regarding designing your own homemade basic induction heater circuit, which can be also used as an induction cooktop. Basic Induction Heater Concept You might have come across many DIY induction heater circuits online but nobody seem to have addressed the crucial secret behind implementing […]
4 Automatic Day Night Switch Circuits Explained
The 4 simple light activated day night switch circuits explained here can all be used for controlling a load, normally a 220V lamp, in response to the varying levels of the surrounding ambient light. The circuit can be used as a commercial automatic street light control system, as a domestic porch light or corridor light […]
Grid-tie Inverter (GTI) Circuit Using SCR
Grid-tie inverter concepts may appear to be complex due to the many criticalities involved with them, however with some intelligent thinking it could be actually implemented using primitive technologies. One of the ideas has been explored here. Introduction The discussed idea of a simple grid-tie inverter circuit was suggested by one of the interested readers […]
