How to Build a Simple Solar Cell Circuit using a 2N3055 Transistor
Anyone wants to know how solar panel work? We can try How to build a Simple Solar Cell Circuit using a 2N3055 Transistor at home which is possible. If we like electronics and know transistor then we will enjoy this project. This model is not big and cannot give power to house but very good […]
Simple Transistor Relay Driver Circuit
Small switch we call transistor is inside almost all electronic thing. But transistor cannot handle big power by itself. So we have used Simple Transistor Relay Driver Circuit which is like a special adapter for transistor. This help small signal from transistor to control big relay switch. With this we can turn ON or OFF […]
Simple Temperature Indicator Circuit using a Single Transistor
To make a Simple Temperature Indicator Circuit using a Single Transistor is not so hard like people think. This article tell how anyone can build this easy circuit using one diode, one transistor and some other small parts. What is a Temperature Indicator Circuit using a Single Transistor: Using one transistor, temperature indicator circuit is […]
Simple Current Limiter Circuit using Transistors
Simple Current Limiter Circuit using Transistors gives tutorial to show how to make a circuit that stop giving too much power to other electronics. It helps to protect from overload by using two transistors and one special resistor. What is a Current Limiter Circuit using Transistors: A transistor current limiter circuit stops too much current […]
Simple Voltage Regulator Circuit using Transistor and Zener
This Simple Voltage Regulator Circuit using Transistor and Zener work like bodyguard for electricity. It uses one transistor like door keeper and one special Zener diode to keep voltage not going up-down. Zener diode gives fixed voltage and transistor follow that voltage to keep same for our device. This project is good when voltage goes […]
