The following post discusses a simple hum filter circuit which can be installed between an audio input source and a power amplifier, so that any possible mains hum frequency within the audio signal is blocked and only the clean audio frequency is allowed to go through. Introduction As the name suggests, hum noise is in […]

Simple E-Bike Circuit [Electric Bike]
This E-bike or electric bike circuit I have explained below can be used as the control circuit for constructing a homemade E-bike, with the help of a permanent magnet motor DC (PMDC motor), and a Li-Ion battery. An electric bike is basically a bicycle powered through a motor and a battery, which does not require […]
Simple Digital Timer Circuit with 2 Digit Display
This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through […]
Simple Vertical Axis Wind Turbine Generator Circuit
In this post I have explained a simple vertical axis wind turbine generator circuit using ready made high power generator dynamo and a vertical axis wind turbine mechanism. The idea was requested by Mr. Taibani. Circuit Objectives and Requirements Hope you’re doing well. Firstly thanks for all the great knowledge & information you have given […]
Simple FET Circuits and Projects
The Field-Effect Transistor or the FET is a 3 terminal semiconductor device which is used for switching high power DC loads through negligible power inputs. The FET comes with some unique features such as a high input impedance (in the megohms) and with almost zero loading on a signal source or the attached preceding stage. […]
Simple SCR Battery Charger Circuit
In this post I have explained a simple yet accurate SCR triggered battery charger circuit which can be used effectively for charging all types of battery, which includes, lead acid battery, Ni-Cd battery banks, Li-Ion battery, etc. This SCR charger can be seen implemented in most automobile garages, and is very popular among auto mechanics, […]
