LCD 220V Mains Timer Circuit – Plug and Play Timer
In this post we are going to make an LCD 220 V mains operated timer using Arduino whose countdown time can be witnessed via 16 x 2 LCD display. Introduction The proposed LCD timer circuit is general purpose timer with display and few buttons for setting the time. Once the time is set output goes […]
Simple 220V AC Fan Regulator Circuit using Push Button
In this post we learn about this 220V AC electronic fan regulator circuit using a push button which changes speed step by step with each press. We press the button, then circuit cleans the signal, counts it properly, and then selects a relevant fixed speed level. Each button press moves the fan from OFF to […]
12V DC to 220V DC Boost Converter Circuit
In this article I have explained a very simple method of acquiring 220V DC from a 12V DC source. The idea utilizes inductor/oscillator based boost topology with the help of the IC 555. Circuit Operation Now let us learn more about this simple 12V to 220V DC boost converter circuit, which is built around IC […]
How to Design Customized 220V SMPS Circuits
We many times think that how we can make a SMPS circuit, and we feel that this is very complex. But that is not so because we can do this by following simple manual calculations step by step. We only need to know that SMPS design is always starting from the transformer. We cannot make […]
How to Make a 220V to 110V Converter Circuit
In this post we will unravel a few homemade crude 220V to 110V converter circuits options which will enable to user the user use it for operating small gadgets with a different voltage specs. UPDATE: An SMPS circuit is the recommended option for building this converter, so for an SMPS 220V to 110V converter design […]
