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 […]
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. This circuit work like translator, it take big AC power from wall and change it to smooth DC power so […]
How to Increase Voltage Output of 7812,7805 ICs
It is good to know How to Increase Voltage Output of 7812,7805 ICs chip but not a really good idea. These chip are made to give fixed voltage like 7812 give 12V and 7805 give 5V. Better way is this: If we want other voltage just buy other voltage regulator chip. There are many different […]
Variable Power Supply Circuit using 7805 or 7812 ICs
This Variable Power Supply Circuit using 7805 or 7812 ICs work like smart adapter. It use chip like 7805 or 7812 which normally gives 5V or 12V and add some other parts like resistor and turning knob like potentiometer. These extra parts help change the voltage up or down so we can set what our […]
