In this post I will show how to construct a circuit for an Electronic Voting Machine using Arduino and SD card module where the election data is stored in the SD card. UPDATE: This circuit has been upgraded to an improved version in which the results can be viewed over an attached LCD display, you […]

Make this DIY Spot Welding Machine using MOT and IC 555
Building a spot welding machine at home, it does not really need those complex SMPS circuits or costly stuff, nope. Instead a much simpler way is there, which people use, and it works quite well. We can use a microwave oven transformer, that MOT, and then add a small timing circuit with it, so now […]
Washing Machine Motor Agitator Timer Circuit
The article details a circuit design for controlling a washing machine motor agitator through a preset time sequence which also includes an alternate reversing of the motor rotation. The circuit was requested by Mr. E.Rama Murthy. Technical Specifications I am having old washing machine which is good working till now. Of late, its PCB has […]
Lathe Machine Over Load Protector Circuit
In this article I have explained a simple overload cut off circuit for safeguarding heavy mains operated machines such as a lathe machine. The idea was requested by Mr. Howard Dean. Technical Specifications May I first say I have very little knowledge of electronics although I could follow a simple diagram. I operate a small […]
Mini Welding Machine Circuit for Small Welding Jobs
A welding machine is an electrical device which is able to generate a very high current at relatively low DC voltages. This high current output can be suitably used for creating the intended welding arcs and welding joints. The welding joint is created by fusing the welding rod on the joint area through a high […]
Adjustable Drill Machine Speed Controller Circuit
The proposed variable drill speed controller circuit maintains a constant (adjustable) speed over the drill machine motor, regardless of the load. One of the most used power tools is the power drill machine. Despite its innumerable advantages, the power drill has one major setback – constant high speed for many applications. Even when there are […]
