How to Make a Simple Op-Amp Circuit
Imagine two whispers one with little louder. Op-amp is smart listener and it hears only the difference and ignores background noise; also it makes small difference bigger using voltage gain. Hence, this Simple Op-Amp Circuit helps boost weak signals in electronics. Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt unless […]
Simple Two Transistors Amplifier Circuit using 1.5V Battery
This Simple Two Transistors Amplifier Circuit using 1.5V Battery works like loudspeaker for small sounds, as it uses 2 small parts called transistors and 1.5V battery to make weak sound strong. Also, it is simple mini amplifier which are good for small projects for making music sound better. Circuit Working: Parts List: Components Values Quantity […]
Simple Automatic Battery Charger Circuit using One Transistor
This post shows very easy way to make Simple Automatic Battery Charger Circuit using One Transistor and with few parts. Also, this circuit charges battery by itself like small machine, as it uses only one transistor, one resistor and one LED. Furthermore the circuit is good for charging 9V battery where LED shows when charging; […]
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 […]
Simple Heat Sensor Circuit using a Single Transistor
To begin with, this Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change; also the transistor work like a door and if temperature changes it opens or closes for electric. So […]
