NiMH Battery Charger Circuit
This NiMH Battery Charger Circuit is like special water can for NiMH batteries which are the same batteries inside camera, toy and other devices. Normal charger maybe not be so good for these batteries but this NiMH charger circuit give just right power and make battery work good and last long time. Circuit Working: Parts […]
Simple Adjustable Zener Diode Circuit
Think like small switch which controls how much voltage go through. A normal Zener diode works like a fixed switch that allows electricity to pass only when the voltage rises above a certain level, but this Simple Adjustable Zener Diode Circuit works more like a flexible dimmer switch. We can also change voltage level using […]
Simple 5V Switch Mode Power Supply Circuit using IC LM2674
This Simple 5V Switch Mode Power Supply Circuit using IC LM2674 work like charger for electronics but better; as it take strong electricity which is more than 5 volt and make it just 5 volt. A 5V supply provides perfect power for small electronic devices and project boards, also this circuit uses a special chip […]
Simple Power Strip Surge Protector Circuit
Simple Power Strip Surge Protector Circuit is like hero for our plugs, they help protect our devices from big shock of electricity called power surge or spike. Also, this surge can come when storm happen or when other machine turn ON or OFF. Inside power strip a special part called MOV take this extra electricity […]
Simple 2 LED Battery Status Indicator Circuit
This Simple 2 LED Battery Status Indicator Circuit work like gas meter but for battery, as it uses LED lights to tell how much power battery still have. One light mean battery is full another light mean half power and last light mean time to charge. Also, it use small parts like resistors, Zener diodes […]
