I’ve been kicking around the idea of making a Frequency Central tiny PSU or StupidUSBPower for doing a round of prototyping, but then I remembered that I had a circuitspecialists.com psu / breadboard thing sitting in the back of my studio from when I used to do more electronics work. Anyway its got variable 0–15, 0 – -15 @ 500ma and 5v @ 1a built in. I’m really new to bi-power power.
Should this thing work fine for testing and prototyping eurorack-powered circuits, or does anyone else out there use anything like this? Is there a simple way/circuit to test it? I imagine there might be an issue with the ground being attached to earth ground and not the ± circuit ground. I can get +12 and -12 when metering the corresponding terminals to the ground terminal as seen in the pics!
This link is to a newer version. Mine’s the same but w/o the LCD screens.
If this could work it might prove to be a cheap and effective way to get a minimal standalone system for lots of folks to get into prototyping all in one place!
