1.2V to 37V Regulated Power Supply 1.2A

“This project provides a variable output power supply ranging from 1.2 to 37 V @ 1.5 A. Uses industry populer LM317 in TO3 package for delivering variable output voltage.”

Low voltage power supply unit

“In this post we introduce simple and flexible, regulated low voltage power supply unit. This power supply has provision for 4 outputs such as 1.5V, 1.8V, 2.5V and 3.3V. We mainly build this low voltage power …

5A Adjustable Regulated Power Supply

“This project provides a variable output voltage ranging from 1.2 to 32 V @ 5 A. Project based on LM338K IC, LM338K is adjustable 3 terminal positive voltage regulator capable of supply in excess of 5A over a 1.2V …

Portable Adjustable Mini Powersupply

“As most of my project involve electronics of some sort, having a good power supply is essential to be able to meet the demand of different power requirements. So I built me a bench-top power supply from an old ATX …

Short circuit protection for (almost) any power supply

“This instructable is about a universal short circuit protection that I’ve designed to use in bench power supplies. I’ve designed it to fit in most power supplies circuits. In order to this circuit fit in your bench power …

Power Supply for 5V and 3.3V

“I normally use a USB port as power supply for my projects. Some ICs need 3.3V instead of 5V as Vcc. Therefore I decided to build a small power supply. It uses a range of 7-14V (I use 7V …

Simple DIY lab power supply

“I was getting a bit frustrated with my old lab power supply, a Manson EP925. I bought it second hand many years ago during my student years. The problem with it is that it has only one output. For many …

Home Built Bench Power Supply using ATMEGA328P

“My workshop has a couple of bench power supply’s, one is an old Farnell TOPS 3D 3-rail tracking job, and the other is a 3-rail CSI CSI3005XIII with Constant Current functions. The farnell is all analogue but has no …

3A Variable bench PSU with digital readout on colour display using ATMEGA8

“I am playing with electronics since i was a child and made numerous circuits.But still now,i didn’t made any power supply unit for general purpose use.So tired of making PSU for each circuit,I decided to …
