Many people over the internet have already found out the usefulness of having an ATX PSU, often salvaged from old computers, on their bench. It can be quite easily converted into a lab bench power supply (owners of a real one, please don’t kill me).
There are lots of videos on how to add binding posts to your PSU and how not to, but I didn’t like any of these solutions. I tried the first one, but my power supply was so small and tightly packed that wires and binding posts wouldn’t fit right in it.
Yet, I felt like it lacked some features I needed. I wanted some USB ports to power my rPi and charge my Nexus 5, and an adjustable voltage output. Furthermore, my PSU had a 24-pin ATX connector.
While I still consider myself a beginner in the enormous world of electronics, I decided to look up some guides on how to design a PCB (this time I’ve gotta thank you, Sparkfun! Both yours and Adafruit’s libraries and tutorials rock!) and have a try at it.
Fast forward some days later, my very own ATX breakout board was born.
