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 […]
Using a Reed Switch as a Current Monitor Circuit
Reed switch is small switch which works with magnet. When wire is near it has current and it makes magnetic field. This magnetic field make reed switch turn ON or OFF depends how it is made. It help to know if current is there. Circuit Working: Parts List: Component Type Description Quantity Resistor 470Ω 1/4 […]
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. Sun moving in sky the whole day. This circuit have sensor it sees where sun goes and change panel direction by itself. When panel always faces the sun it get […]
Simple Water Softener Circuit
In this post we will give all easy information about Simple Water Softener Circuit 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 cost […]
Transistor 2N3055 Circuit with 1.5 Million High Gain
Transistor 2N3055 Circuit with 1.5 Million High Gain is like normal volume knob it can make sound more but not too much. If we want very loud like 1.5 million we need to trick it little bit. One way is it uses two transistors together like double volume knob and this is called the Darlington […]
Adjustable Power Supply Circuit using IC TDA2030
This Adjustable Power Supply Circuit using IC TDA2030 can change the voltage it uses small trick which is little bit surprising. The chip TDA2030 is normally for making speaker sound loud and can also work like voltage controller. With smart circuit design it gives steady DC voltage. We can change output which is good for […]
