In this post we talk about a couple electronic drum sound simulator circuits which can be used for replicating actual drum beat sound electronically, using a few op amps and few other passive electronic components. Using Capacitor as the Sensor Instead of Piezo Conventional electronic drum kits incorporate the use of piezo disc affixed to […]

How to Make a Zero Crossing Detector Circuit
Making a zero crossing detector circuit is actually very easy and it could be effectively applied for protecting sensitive electronic equipment against mains switch ON surges. A zero crossing detector circuit is mainly used for protecting electronic devices from switch ON surges by ensuring that during power switch ON the mains phase always “enters’ the […]
LED PWM Controlled Tubelight Circuit
In this post I have explained a 555 based PWM circuit which can be implemented as a 150 nos or more LED light intensity controller circuit. The idea was requested by Mr. Anil The Circuit Request I want to run 150 nos LEDs of 5mm with help of IC 555 on Pulse & continuous mode. […]
How to Make a Ghost Detector Circuit
In this article I have explained to make a simple ghost detector circuit or a paranormal being detector circuit for quickly investigating a possibly infested area. Introduction Do you believe in the existence of ghosts? Well some of you may answer positively while some may just nod their heads showing sheer skepticism regarding the issue. […]
How Shunt Regulator TL431 Works, Datasheet, Application
In this post I have explained how a shunt regulator IC works typically in SMPS circuits. We take the example of the popular TL431 device and try to understand its use in electronic circuits through a few of its application notes. Electrical Specifications Technically the device TL431 is called a programmable shunt regulator, in simple […]
Thunder Lightning Detector Circuit – LED Blinking in Response to Thunder
This simple circuit will enable you to visualize distant thunder lightning through a correspondingly choreographed LED flashes, exactly in accordance with the lightning that may be taking place somewhere in the distant sky, the response will be simultaneous and thus much prior to the sound that may reach your ears after a few seconds. RF […]
