7 Easy Sawtooth Waveform Generator Circuits using UJT, IC 555, and Transistors
In this post I have explained how to build 7 types of easy sawtooth generator circuits, using BJTs, UJTs, and IC 555. In a sawtooth waveform the voltage increases slowly in a slanting manner or diagonally, then as soon as it reaches the peak, the waveform voltage suddenly drops to zero. Once it drops to […]

The idea was requested by Mr. Vamshee Technical Specifications My name is Vamshee and i am from hyderabad , India I am a small time entrepreneur looking to promote and sell new age products into the […]
How to Make Step Down Transformers
A step down transformer is a device which reduces a higher AC potential to a lower AC potential as per its winding ratio and specifications. In this article we are going to discuss how to design and construct a basic step down transformer which are typically applied in mains-operated power supplies. Introduction This will likely […]
Treadmill Motor Speed Controller Circuit
In this post I have explained a simple, accurate, high torque treadmill motor speed controller circuit which may be effectively installed in similar units for acquiring PWM controlled variable speed feature. The idea was requested by Mr. Samuel. Technical Specifications I’ve a treadmill whose power failed completely…it had been imported from china and it’s like […]
How to Make a PWM Controlled Fan Regulator Circuit
In this article we look into a simple 220V mains PWM controlled fan or light regulator circuit which does not require a microcontroller or costly triac drivers for the intended operations. Capacitive Phase Chopping All Ordinary types fan regulator and dimmers which rely on capacitive phase chopping technology have one drawback in common, these generate […]
