This article show how to make small and Simple Transformerless Power Supply Circuit which changes big voltage from wall socket to small voltage for electronics. Also, this circuit does this in smart way with no need of big transformer. WARNING: High voltage is dangerous, so only make this when adult is there and watching. What […]
Power Supply Circuits
Bench Power Supply Circuit
To begin with, this project is for Bench Power Supply Circuit which is easy to use and works good and we can change voltage and see current. What is a Bench Power Supply: Bench power supply circuit is useful device which gives steady and control power for working in lab, workshop and testing electronics. Also, […]
Constant Voltage, Constant Current Battery Charger Circuit
This Constant Voltage, Constant Current Battery Charger Circuit teaches about how to make smart 12V battery charger! also, it uses one common chip named LM317 IC. Further, this charger give two thing always same: voltage and current. Voltage help stop too much load on battery and current ensures battery charges slowly and safely. What is […]
High Current Adjustable LM317 Power Supply Circuit
In this post, IC LM317 is chip for controlling voltage but it give only 1.5 amp current, also we can add one more part called TIP35 transistor with LM317, in which LM317 tell it and this transistor act like a follower. Now with this transistor LM317 can handle big current up to 10 amp. Also, […]
Simple Current Limiter Circuit using Transistors
To begin with, this Simple Current Limiter Circuit using Transistors gives tutorial to show how to make a circuit that stop giving too much power to other electronics. Also, 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 […]
Simple Voltage Regulator Circuit using Transistor and Zener
This Simple Voltage Regulator Circuit using Transistor and Zener work like bodyguard for electricity, because it uses one transistor like door keeper and one special Zener diode to keep voltage not going up-down. Furthermore, the Zener diode gives fixed voltage and transistor follow that voltage to keep same for our device. Also, this project is […]
