Homebrew PCBs

I have something like that.
It has x10 and x20, the clearance is, lets call it workable.
could be more for soldering but better than nothing.

I rarely use it, for soldering i only used it to solder the bridges
on a amd athlon cpu (to make it faster).

it is no that practical for soldering, my eyesight is quite ok (in close 
range).
It is quite good for inspecting other things...

A sturdy boom mount should be no problem, the range in which the focus is 
ok is wide enough i think.
Maybe you can build it so it doesn't need an additional desk (like pivot it 
to the side/back if not in use)

You will need the light from the top. My unit has through-light too but i 
never need it.
Think about buying a more expensive unit with built-in light and 
transformer.
