and my question is ... would the thing just short and get damaged??? all the electronic parts are submerged in liquid...
Geia sou,
I don't comment on the PC in mineral oil stuff (bad idea for a variety of reasons). I'm just concentrating on this particular comment.
Come on, you are a student, right? Why do you suppose that all liquids are automatically conductive?
Have you heard about such thing as the resistivity? Go search for the resistivity of air - 1.3e16 to 3.3e16 ohm-meters
How much is the resistivity of mineral oil you ask? - around 1e11 - 5e10 ohm-meters which is OK with regard to that application.
Have you not thought about doing a quick search on google before asking this question in the forum AND leaving a comment on Youtube.
Excerpts from Wikipedia:
As reported by the ancient Greek philosopher Thales of Miletus around 600 BC, charge (or electricity) could be accumulated by rubbing fur on various substances, such as amber. The Greeks noted that the charged amber buttons could attract light objects such as hair. They also noted that if they rubbed the amber for long enough, they could even get an electric spark to jump.
In 1600, the English scientist William Gilbert returned to the subject in De Magnete, and coined the New Latin word electricus from ... (elektron), the Greek word for "amber", which soon gave rise to the English words "electric" and "electricity."
The electrogenic properties of electric rays have been known since antiquity. The ancient Greeks used electric rays to numb the pain of childbirth and operations.[2] In his dialogue Meno, Plato has the character Meno accuse Socrates of "stunning" people with his puzzling questions, in a manner similar to the way the torpedo fish stuns with electricity.
Apparently, [some] today's Greeks ask ignorant questions on Internet.
PS: I love your country, I'm spending most of my summer vacations there.
