Breadboard Power Supply
5V breadboard mini PSU
A simple tutorial on making a 5V power supply unit by chr at instructables.
You can Connect to 9V battery, 12V or any other DC power source from 8 to 18 volts.
Make A Breadboard Power Supply
In this instructable Nerdz will show how you can use a fixed voltage regulator as a adjustable one. The advantage of this is method is that your minimum output voltage isnt 2V, such as in the LM317T, but your minimum is what ever voltage regulator you used. For example, in this project he use a LM7805 as a adjustable Regulator, It gave an adjustable Voltage from (Vin-2) to 5V.
The Radioshack, Adjustable, Breadboard Power Supply.
A Great instructable from kersny. This Instructable will show you how to build an adjsutable breadboard power supply entirely from Radioshack parts. It can provide multiple voltages directly to the power rails on a prototyping breadboard. This could be useful for people on a low budget, who don’t like to order parts online, or who need a good weekend project.
Tiny Breadboard 5v PSU (with two output modes)
steinroeland has got us a PSU. This tiny discrete 5 volt PSU is ideal for breadboard projects. You can stick it between the break of the power lines on your breadboard. With a jumper switch you can provide 5 volt for the whole power line or 5 volt on the right side and the input source on the left side. Which is very handy for projects who needs a voltage regulation. For example stepper motor controlling circuits; 5 volt for logic level and 12 v for the motors or relay controlling or RGB LED controlling, etc. The tiny PSU can be supplied by any regular AC/DC converter(8-18v).
LM317T adjustable power supply
This is an Instructable by vaati that tells you how to make an adjustable voltage regulator, which has endless applications. It can be used to test your LED’s and other low voltage loads, and there is another terminal for higher voltage applications.
ATX Desktop Power Supply
Desktop Power Supply from a PC
If you find building your own desktop powersupply from a recycled PSU and a few parts from the local electronics store appealing, then grab some tools, pour yourself a cup of coffee (or personal preference) and let’s get started as Andy Batts has got us some interesting solution for your ATX lying around for a while.
Power your breadboard with USB
it is safe to say that most of the people who make (big or small) electronics-projects have a pc or laptop in their hobby-corner and a lot of projects need 5V for IC’s or microcontrollers. So using power from a USB cable isn’t that farfetched .In this Instructable janw will guide us make a very simple power supply with only the USB-connector and a power-on led. But you can add whatever you fancy such as a power on/off switch or or a regulator to get 3,3V
How to Convert a Computer ATX Power Supply to a Lab Power Supply
Computer power supplies cost around US$30,but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and very tight voltage regulation.
That’s all for this moment!

This was a Fantastic wordpress post, I will save this post in my Newsvine account. Have a good night.
Another a informative good read by the author hope to read more really soon.
Maybe you could change the post name title Roundup : Power Supply Unit to more catching for your webpage you create. I liked the the writing all the same.
That insgiht would have saved us a lot of effort early on.
Awesome article over again. I am looking forward for more updates=)
I’m grateful for you because of this excellent content material. You genuinely did make my day :
