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 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 […]
High Voltage Fence Charger Circuit
This post shows how to make High Voltage Fence Charger Circuit. It does not cost much and is safe to stop wild animals and keep our pets inside fence. It cheap and easy to fix and is better than normal fence. WARNING: Electric fence can kill if wrongly made. Only do with adult help. Circuit […]
