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 […]
Fast Charger Circuit with Auto Cut Off
To begin with, this Fast Charger Circuit with Auto Cut Off is fast charger for battery like car battery or backup battery; also it charges battery very quick but there is no need worry it wont overcharge. Furthermore, inside circuit there are safety part when the battery is full it stops charging by itself, this […]
30V 1Amp Transformerless Power Supply Circuit
This 30V 1Amp Transformerless Power Supply Circuit works like small adapter for our electronic, as it takes normal high voltage electric and change it to low safe voltage to what our devices need. No large transformer is required because the circuit uses special components such as capacitors and diodes to perform the same function. Like […]
