I am not sure is this the right group to post this kind of question, I hope I am not too much out off topic.
I am quite new to electronics, although I am programming software already for many years. I understand very basic circuit's schematics, but for this

particular one (I saw it on other places also), I am not sure how the lower right part comes into the circuit. I mean, it is totally disconnected from the main part of the circuit. What's the purpose of it and how connects to the other part, can someone explain it to me?
The "mystery part" is a voltage regulator - it will accept 7 - 30 volts, and reduce it to 5 volts for the processor. The point labelled "VVC_OUT" should be labelled "VCC".
All the points labelled "GND" are connected together, and all the points labelled "VCC" (including the mislabelled "VCC_OUT") are connected together.
When drawing schematics, it is common practice to omit power and ground lines, and to indicate the connections with "VCC" and "GND" symbols, or signal names (often called "net labels") to reduce clutter on the drawing.

I will do that. Just, I am still searching for the parts. My country is also very bad in this field (as in many others). I will probably need to order them over the net. I found them on

disent prices I would say and they accept cheques, which is a must in my case.
I remeber you from my previous thread in this group, if you remember AVREasy. I couldn't get it running, so I decided to make something on my own. Just I can't forgive my self, I paid the board 120 euros, while they on the above site are around 30-50 $US.
