(OU.COM)..then, from post to post, browse every link that lies...try to absorpt what can my brain accepted :-) ... everything around my head randomly, because i have not electronic background...but something that never be out of my mind was a toroidal shape and  the wire around it...that was a sexy and attractive form   , so, i've decided to be focussed on toroidal  thing...learning the theory, trying to build a small  toroidal inductor, and follow your every post about  tpu (i want to  experiment by following to build one, but i have no time to spent)...

But something , i have to tell to you all
