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 […]

2 Simple Washing Machine Circuits Explained
In this post I have explained how to make a couple of simple washing machines using a bidirectional single motor with timer and a simple version using cam shaft mechanism, cheaply. In the first design we use a bidirectional, alternately rotating clockwise and counter clockwise with a pause in the middle: Audio/Video Representation Circuit Working […]
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 […]
Electronic Voting Machine with SD Card Module
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 […]
Tennis Ball Throwing Machine Circuit
In article below explains the control circuit for an automatic tennis ball throwing machine, designed to throw a tennis ball through a mechanized catapult machine, controlled with powerful motors. In this article I have explained the motor control circuit which will toggle the catapult mechanism back and forth, with a 2 second time interval, while […]
