Solar Tracker Circuit
Think like small helper robot for our solar panels. Solar Tracker Circuit works like smart assistant which helps solar panels to always look at sun, as sun moving in sky the whole day. Also, this circuit have sensor it sees where sun goes and change panel direction by itself. When panel always faces the sun […]
Simple Water Softener Circuit
In this post we will give all easy information about Simple Water Softener Circuit, as this one small device we can put on our water pipe which will help to make hard water to become soft. Hard water make white stuff build up in pipe and machine and this make them not work good and […]
220V AC to DC Voltage Converter Circuit
This 220V AC to DC Voltage Converter is small circuit like small adapter for our devices. Wall socket gives AC power but many electronics like phone, laptop, LED light they need DC power to work; hence, this circuit work like translator, it take big AC power from wall and change it to smooth DC power […]
Variable Power Supply Circuit using 7805 or 7812 ICs
This Variable Power Supply Circuit using 7805 or 7812 ICs work like smart adapter; it uses chip like 7805 or 7812 which normally gives 5V or 12V and add some other parts like resistor and turning knob like potentiometer. Hence, these extra parts help change the voltage up or down so we can set what […]
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. Therefore, 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 […]
