usually in my free time i play "electronics engineer"

Yes, the question are " what do you do on your free time , what relaxes you ? ..
I am fighting hard here the language barrier , but even those small grammar mistakes ,
never stopped me , from keep trying to communicate.

Well Simon , in Greece we say, that in order to succeed ,
you need to have it ( the passion ), on your blood ..
My father was freelancer cars electrician , the No1 in my town, he was the " perfect " doctor ,
never ever made an mistake in his diagnosis , and he was trained me, up to one point,
because he died at the age of 45 from hart attack, and I was just 16 at that time.
At my 16 , I was in school , getting classes so to become an electrician too , so to continue the successful family business .
After the loss of my father , I lost my way too, and started to work with electronics,
I love it , more than anything.
By bringing back to life , damaged devices ( called as not repairable ) by other local technicians,
makes me feel , like a small God
No matter the time that I will spent , no matter the cost .. I will get it fixed , even If I have to invent the solution , by using similar parts , and if its an mechanical damage, I am creating the parts.
So I do understand , at list the source of your passion
