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 […]
Newly Updated Circuit Projects:
Build this Open Baffle Hi-Fi Loudspeaker System with Crossover Network
The open baffle hi-fi, high quality speaker design introduced here provides a substitute to the common loudspeaker housing. Its sound emission pattern resembles electrostatic pattern. It works without enclosure or housing for the woofers, although employs normal dynamics for the drive units. The reproduction provides extremely ‘spacious’ impact on the ears.

Precise Battery Capacity Tester Circuit – Backup Time Tester
The precise battery capacity tester circuit explained in the following article can be used for testing the maximum backup capacity of any rechargeable battery in real time. By Timothy John Basic concept The circuit works by practically discharging a fully charged battery under test through constant current, until its voltage reaches the deep discharge value. […]
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 […]
IC 7805, 7812, 7824 Pinout Connection Explained
In this post I have explained how to connect common 78XX voltage regulator ICs such as 7805, 7812, 7824 etc for getting fixed regulated output voltages at 5 V, 12 V, or 24 V outputs respectively. The input voltage must be at least 3 V higher than the desired output voltage. For example, if a […]
