HAPPYYY

I
AM
SO
HAPPY

That's all I could say
This morning I unbelievably managed to finish ALL sections in my SS paper, although the quality of the answers are still questionable :D
But most importantly, I did it

Then just now
after struggling for hours with my new-second-hand camera
with all the delicate wires, connectors, and bolts
and to taste the electric force of a 300V electrolyte capasitor
I finally succeed in modifying it with a simple but useful "filter"
(it is a pity that I screwed up the LCD, otherwise it could be perfect...)
I am ready to test it on the field [smile meaningfully from ear to ear]

I officially want to thank HELiX for his brilliant idea
