Simple 220V LED Night Lamp Circuit
This Simple 220V LED Night Lamp Circuit design make night light work straight from home power plug which is usually 220V AC. It does this by using small transformer or special capacitor to drop voltage low so LED lamp can work safe. Circuit Working: Parts List: Type Value Quantity Resistors 10Ω 1W 1 560k 1/2W […]
220V Lamp Flasher Circuit using IC 555
This 220V Lamp Flasher Circuit using IC 555 uses one special chip IC 555 to make normal bulb blink like party light. The chip make ON/OFF signal. This signal connects to transistor or triac which work like switch for bulb power. When power goes ON and OFF fast then bulb start blinking in fixed speed. […]
Simple LED Tester Circuit
This small and Simple LED Tester Circuit is like a small doctor for LED. It helps to see if our light LED is working or not. Think like a small setup one battery, some small resistor like tiny traffic light for electric and clip to put LED. When we put LED in circuit check if […]
Simple Backup Light Circuit
Think our lights are as a safety friend this simple backup light circuit is like a good helper for our lamps. It have two or more lights and smart system. If one light stop working the other light turn ON by itself and there is no need to stay in dark. Very useful in important […]
1.2V NiMH Cell LED Flashlight Circuit
This small and 1.2V NiMH Cell LED Flashlight Circuit works like supercharger inside flashlight. Normal flashlight with NiMH battery does not use full power from battery. But this circuit have special booster which takes low 1.2 volt and make it higher like 3.3 volt so LED can glow more bright. So we can use full […]
