This Simple 220V White LED Flood Light Circuit is like a small power machine for big bright light, as it takes normal home current 220V and make those special white LEDs glow. Also, the circuit works like converter and change big voltage to small one which are good for LEDs. Inside small parts like resistors, […]
LM317 IC Solar Charger Circuit with Auto Cut off
LM317 IC Solar Charger Circuit with Auto Cut off works like smart nanny for a battery, as it takes sunlight and charge battery but stop at right time. Also, inside it have one smart chip called LM317 which control charging and gives battery only needed power which is not too much. The best part is […]
Simple Fatigue Testing Circuit
This small and simple Fatigue Testing Circuit is a fun way to check whether someone feels tired or not! it makes LED blink very fast and we can change how fast it blink. Also, if we are not tired, we can still see the LED blink even when it flashes fast; however, if we are […]
Simple Earth Fault Indicator Circuit
Simple Earth Fault Indicator Circuit is like safety guard for electric system, as it checks if electric connects to ground by mistake, like when bad wire touch metal box. Also, this is very important because if there is an electric leak the machine may break and cause a fire or may shock people. Circuit watch […]
Mains AC Transients Indicator Circuit
Think like anyone have one small device to check its home electricity going up and down; then this Mains AC Transients Indicator Circuit is same like that but only for sudden high voltage. These high voltage come from lightning and big machine turning ON or power change, also this circuit have one sensor who is […]
