“This is a simple adjustable bench power supply I built to help me in my instructables. 8 ) Some time ago I build another using a computer (ATX) power supply, but this kind of solution provides fixed values: 3.3, 5 …
“Tiny low current 9 VDC Regulated Power supply designed around bipolar transistor and zener diode. The circuit is known as series voltage regulator or emitter follower voltage regulator. The unregulated supply fed to input and the circuit regulate the voltage …
“Some time ago i bought a nice 5V switching mode PSU to have enough power for a raspberry and all stuff in want to connect to it. In another instructable i wrote some time ago, i showed how i like …
“The Step-Up DC-DC Converter project provides 28V, 175mA output with input of 12V DC. The MC34063A IC is heart of the project from On semiconductor. The MC33063A is a monolithic control circuit containing the primary functions required for DC …
“Every electronic hobbyist needs a variable power supply for prototyping and testing, but they can be very expensive. I will show you how to build a cheap yet reliable power supply.”
“When you are working outdoors and don’t have a generator a 12V battery like the one you have in your car is a good power supply. But sometimes 12V just don’t cut it. For this I put this …
“This project is a simple linear bench power supply with adjustable voltage and current. It is meant to be a learning experience, putting ideas of circuit design, feedback, stability into practice building a complete practical power supply. I have intentionally …
“This is cheap adjustable 0-30V 3A Laboratory DC Power Supply circuit. It is high efficiency regulator circuit by using IC regulator UA723 and TIP3055 as power transistor so easy to install. It is designed to protect over current load maximum …
“This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum …
“This is a small size power supply with low cost and easy to make that only taking about 5 more hours. I was very happy with it and would share with you.”
