How to Convert a Computer ATX Power Supply to a Lab Power Supply

How to Convert a Computer ATX Power Supply to a Lab Power Supply
Edit Article Edited by Abizarl, Krystle C., Jack Herrick, Vertent and 42 others 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 reasonably tight voltage regulation on the 5V line. On most power supply units (PSUs), the other lines are unregulated. Ad Steps 1Look online or at your local computer store for an ATX computer power supply, or dismantle an old computer and remove the power supply from the case.Ad 2Unplug the power cable from the power supply and turn off the switch on the back (if there is one). 13 Plug the power cable into the back of the power supply and into an AC socket. Tips You can use your power supply 12V output as a car battery charger! Warnings If you suspect the power supply is damaged, do not use it!

Bench PowerSupply - My Scratchpad Ive increasingly found I need a better power supply while working on my Arduino projects. So here is my version of the standard ATX power supply conversion wrapped in a nice metal case I had laying around. Heres the finished product. Im quite pleased with how it turned out. Basic Electronics {*style:<b> Get a quick start by scrolling down to the introduction below this menu table.

Computer Power Supply to Bench Power Supply Adapter Step #13: Add Labels For Each Pair of Terminals PrevNext To help keep track of the different voltage outlets, I labeled each pair of terminals.

Resistor Color Codes & Component Identification Resistor Color Code Bands& Other Component Identification Resistor Color Code Identification While these codes are most often associated with resistors, then can also apply to capacitors and other components. The standard color coding method for resistors uses a different color to represent each number 0 to 9: black, brown, red, orange, yellow, green, blue, purple, grey, white. On a 4 band resistor, the first two bands represent the significant digits.

antenna basics Antennas, to quote a friend, are one of life's eternal mysteries. "All I'm totally certain of is that any antenna is better than no antenna and the antenna should preferably erected as high and be as long as is possible or desirable". Here we will discuss the very basics of antennas including the the amazing terminated tilted folded dipole antenna. Each type of antenna will eventually have its own page. Raspberry Pi as an Ad Blocking Access Point This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web!

Apple’s Middle finger: It’s Pointed at You Let’s get this clear right off the start: Apple makes some absolutely fantastic products. The issue is not with the quality of their products, but the attitude and manner in which the company operates. They are giving their customers the middle finger, and for some reason the customers are thanking them for it. I make the argument that it doesn’t have to be this way. If we want Apple to stop treating their customers with disrespect, we need to stop praising them for doing so. SPICE Simulation Models 1.
