Kind of a wierd one. Well, Delphi automotive systems contracted the company I worked for to R&D Design the dc-dc converters for thier 2003 fuel cell powered BMW's(total R&D project). And I was the lead electronics technichian on the project. I spent many a long night with soldering iron in one hand and ossciloscope lead in the other to pull off making these thing operate. So I dubbed myself the Delphi Pro in the lab, and it has stuck ever since! Here I went with Delphipro500 but it wouldn't let me so it is Delphipro5.
Plus the whole greek Oracle of Delphi thing,, you know she was in a cave fortelling the future to everyone.
Then 100's years later scientists discovered an Ethylene Gas vapor was rising into the grotto causing her to hallucinate. Kind of funny to think about!
