This electronic candle accurately imitates the flickering flame of a lit wick, but it remains considerably cleaner, doesn’t drip, and poses no risk of setting your interior on fire. It only requires a handful of ordinary components and is powered directly from the mains with minimal energy consumption. Its lifespan will be exceptionally long. How […]

Train Sound Simulator Circuit
The train sound simulator circuit is an electronic circuit that generates a realistic sound that mimics the sound of a train moving on tracks. The circuit is designed to be integrated into a model train set or layout to add to the overall realism of the scene. The sound is produced using a combination of […]
Electronic Drum Sound Simulator Circuits
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 […]
Laughter Sound Simulator Circuit
As the name suggests, this device generates electronic sound, resembling human laughter. BASIC DESIGN To enable the circuit start the proposed operations, it must have a fundamental sound input or frequency for processing. This basic frequency is established through a simple oscillator operating at 1 kHz frequency. The next, requirement would be to process this […]
Loud Pistol Sound Simulator Circuit
The proposed circuit is an oscillator circuit designed to generate a loud pistol like sound over a loudspeaker. A pistol sound generator circuit presented here can be used as button operated starting sound during racing events or marathons, or simply to deter wild animals and thieves in remote areas. The concept could be also effectively […]
Single LM317 based MPPT Simulator Circuit
To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article I have explained how a standard LM317 power supply could […]
