[sdiy] smt placement and soldering..

[harrybissell]

And good glasses.  I'm doing some fine pitch mods Monday, so don't feel
TOO sorry for me.  I'd even suggest special tools... stereo microscope or
long focal length instrument like the "Mantis" that we use at work.

Once you collect the tools its easy. OTOH I'd rather spend the money on a
nicer scope and have BIG parts I can see and touch  :^P
