its quite true what Florian says ... it's really not something you can approach lightly ... at least not without understanding the interactions of components and circuitry architecture. I have years and years of basic experience and good technical skills with soldering etc. myself but even i find it extremely challenging and most often frustrating. this is not to say you shouldnt do it... but you will have to be extremely committed and spend hundreds of hours learning on simpler things maybe. i do not want to discourage you .... nor does Florian ... but its something you will have to work your way up to ...
