Welcome back!

I do enjoy a good quality article about electronics.
I really envy your free time as you can get to play with those.
I am still involved in decorative paining on my house so what I do is still on the macro level.
How did the exams go? Can we be proud of you? :)

Update: You could format the text a little more. Break it into readable chunks and segment it a little. Start the sentences with capital letter, capitalize the first letter of the headings.
It sells your content better, because the content is good.
