Well today i had to spend some time in the lab and since i was gonna be there for a few hours, i thought it might be a good idea to bring along the 220v-->48v PoE injector&PSU that Alex had given me some time ago, and sit down and fiddle with it in hopes of rising it from the dead! :P And what do you know, lucky me...it's now working again ! So wile i was sitting there and enjoying the moment, it suddenly hit me...''why not measure the ripple of the psu?" After all the oscilloscope was right in front of me! So here are a few quick photos, to please the eyes!
