THE DEVIL SUGGESTS
Build a bench power supply from an old PC PSU
A small, properly bounded project: Build a bench power supply from an old PC PSU. Start with a working first version, pay attention to what you notice, and leave yourself with something you can use, understand or show someone.
Do it
- Read the component labels and make a simple plan before connecting power.
- Set up a clear, ventilated and stable work area.
- Build or repair the simplest part first, with power disconnected.
- Inspect the work, then test carefully at the lowest sensible voltage.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
