Like many of you, I wanted to use a lab bench power supply for my electronics. Unfortunately, they can be very expansive so I wondered if there would be an easier and cheaper way to build one. I came across many great instructables explaining how to modify the power supply from an old computer to a benchtop, but they all required skills and tools I don't have. I finally found out that I could simply use a cheap ATX breakout board. This is by far the easiest solution for the conversion of an A...
This is a design for an open source, modular bench power supply with enough features to compete with the mid-range commercial units in the $1000-ish range. This project includes features such as software calibration, programmatic control via USB Raw HID, etc. In its simplest form, it is very affordable, but can be easily scaled up to a larger, more powerful unit.
