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 […]

Rotating Beacon LED Simulator Circuit
In this post I have explained a simple LED flashing beacon circuit which exactly simulates a rotating police beacon light by generating alternating pulses of suddenly rising and fading illumination effect on the connected LED. The idea was requested by Mr. Ankit Agarwal Technical Specifications Can you advice on how to make the following circuit […]
Sunrise Sunset Simulator LED Circuit
In this post I have explained how to make a sunrise/sunset simulator circuit using LEDs and just a couple of BJTs. The idea was requested by Mr. Jerry Circuit Objectives and Requirements The Design As proposed, a simple sunrise and sunset simulator circuit can be implemented using the circuit shown in the following diagram: The […]
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 […]
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 […]
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 […]
