Using a Reed Switch as a Current Monitor Circuit
Reed switch is small switch which works with magnet and when wire is near it has current and it makes magnetic field. This magnetic field turns the reed switch ON or OFF, depending on its design and it also helps us show whether current is present or not. Circuit Working: Parts List: Components Values Quantity […]
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 […]
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 and if we want very loud like 1.5 million we need to trick it little bit. One way uses two transistors together like a double volume knob. People also call this arrangement a […]
How to Increase Voltage Output of 7812,7805 ICs
It is useful to understand How to Increase Voltage Output of 7812,7805 ICs, but this approach is not always a good idea. These ICs provide fixed output voltages by design, with the 7812 producing 12 V and the 7805 producing 5 V. Better way is this: if we want other voltage just buy other voltage […]
Simple 3 Ampere Adjustable Power Supply Circuit using IC LM350
Think Simple 3 Ampere Adjustable Power Supply Circuit using IC LM350 is like super cool power adapter for our electronics project. Also, this circuit uses one chip called LM350 it is strong and give very good power, as tt can give power up to 3 amp and voltage we can change from 1.25V to 25V. […]
