Lots of projects do this. The big issue is you need a PPS capable supply(More and more seem to support it). With that you have full current and voltage control

Without it you get 5v, 9v, maybe 12v(I think it's deprecated or removed, not sure if it still works on new stuff, sadly, because 12v is so common), 15v, and 20v. Plus the new high voltage modes.
- giantg2 5y agoI know there are some PPS that are designed specifically for projects. Usually they are big and expensive. I was really hoping for something cheap. That's why I tried USB wall chargers with a $1-2 step up converter. It works great at 12v with lower amps (.5 ish) but can't handle the higher stuff (1.25-1.5 ish). Then I started looking for higher amp chargers and saw that some will do 12v so I don't need to do the conversion, but I don't know how to signal them to send 12v vs the other voltages. Not to mention they are expensive. I ended up ordering a 120v AC to 12v DC module last night. It's about $5. Now I just need to see if I can find empty wall transformers somewhere to make it look good, or if I have to wonky looking inline project box and bulky clamshell plug.
