[sdiy] stupid solder

[Sowa Roman]

One of the profesors at my Univ. used to say that there's no need
to use higher accuracy ADCs than 12 bits, because thermal junctions
from solder points will create bigger voltage errors than any of those
ridiculous LSBs in high resolution ADCs.

Of course I didn't listen and used 16-bits anyway
