Electronic Candle Flame Simulator Circuit
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 […]
220 V Slow Fade Bedside Lamp Circuit
The operating principle of this children’s night light is to gradually familiarize the child with darkness by gradually reducing the brightness of their bedside lamp. The room’s brightness will slowly fade away and completely extinguish after a duration ranging approximately between twenty minutes and 5 to 7 hours. This duration can be adjusted from week […]
Sound Activated Remote Control Circuit
This sound activated remote control circuit can be used to operate any electrical load ON/OFF, through a double sound command. Thus, the circuit ensures that the load cannot be operated through any random single sound triggers, which makes the circuit very fool proof. Our device will require two shifted sound commands. However, the second sound […]
High Voltage DC Motor Speed Regulator Circuit
In the realm of motor control systems, high voltage DC motors play a crucial role in numerous industrial and automotive applications. Efficiently controlling the speed of these motors while ensuring operator safety and isolating sensitive components can be a challenging task. However, with the advent of advanced technologies, such as optocoupler motor controller power stages, […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
