Here is a low cost and easy to build power supply based on a some Chinese DC-DC converter modules:

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.

Power Supply Specifications

Input: 5v-16v/3A DC

Output: 1.3V – 15.5V/2 Amps

Mixed Output @ instructables.com has build a nice power supply by combining different power modules.

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 power supply Unit (PSU) that worked (and still works) great. However I’ve recently noticed some limitations with having a full fledged bench top PSU.

Power supply is an utmost essential tool for an electronic lab. It comes in handy for powering up various applications and circuits. However a fixed voltage, fixed current power supply is sufficient for basic needs but a variable one is good to have because different circuits and components operate at different voltages and consumes different current. When it comes to an electronic hobbyist’s lab, a good power supply is must to have. Also if the power supply boosts additional features like on board voltage and current display, it comes in handy as one can know the exact voltage at the output terminals and also the current drawn by the load. But in the electronic market, those power supplies are not economic are meant for industrial purpose . Here in this article I present an economical and cost effective yet efficient variable bench power supply that is capable of providing 1.2 to 25 Volt variable supply up to 5 Ampere through one channel while 5 Volt, 1 Ampere and 12 Volt, 1 Ampere supply through other two channels thus having one variable and two fixed supply channels.

How to build your own linear adjustable power supply based on LM317. In this tutorial I’ll explain how linear power supply works, what parts it consists of and a lot of small details, like how to calculate smoothing capacitor value, or how to choose a transformer. Plus you’ll see how to build an actual power supply.

Adjustable LM317-based power supplies are an easy way to get custom voltages for your benchtop. Also check out the MIC2941 which has some nice benefits such as ultra-low dropout, 1.25A current output and a separate biasing pin. Its nearly a drop in replacement for the LM317 – albeit a little more expensive.

i have been working on a linear bench power supply, and have come to the conclusion that the cost of parts will be more than what i cam buy an assembled one for, however i will share what i have come up with so far so that any one interested will be able use what i have started.
