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 […]
Simple Adjustable Power Supply Circuit
Many electronic things need clean DC power to work good. This post show how to make one easy Simple Adjustable Power Supply Circuit. It changes dirty DC power to clean power and it uses one chip called LM338. This circuit take DC from 5 to 34 volt and gives clean DC from 1.25 to 30 […]
