Thanks for reply, means a lot to me that someone actually read this stuff :)
Iam not that into electronics but like to use it when i got chance so Iam lacking a lot of background knowledge and its fascinating to see how tech has improved over the years and becomes eventually available to whole wold.

It is simply amazing what Arduino can do and all in such small dimensions and even more with Raspberry, PLC and other controllers.

On the clone thing, as Im on student budget and all this is just for fun not anything work related and what would work for longer period of time, but if I wold build something to last I would use probably original.
