I am using plenty/a lot. I have already learnt that from your projects :)

This is a little hard yet. I do not have a good soldering station now
Well, it is good (zd 931), but the pencil does not have a small tip, so I just
touch a bit the the things, and then I take a bit of tin on the tip
and just touch really fast. I check the join with tester and if I get
the "beep" I do not touch it anymore; because if I do, I often
break the join and then I can not fix it anymore

The same that in 2). I try to do, but if it is really hard then I do
not try harder to continue.
