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!

Καλορίζικη η πρώτη δημοσίευση <-- κάλιο αργά ... Υπάρχει ακόμη ένα νεκρό PSU 18V/2A που δεν πρόλαβε να κλείσει 24 ώρες στον Dait-2 και φυσικά είναι στην διάθεσή σου !!
Επίσης αν ψήνεσαι για βόλτα εκεί ψηλά στον Υμηττό, βάλε φωνή!
ok thanks!
Θα χρειαστώ και λίγη βοήθεια με τις φωτογραφίες! Δεν έχω καταλάβει πως γίνετε να φαίνονται?!
