Homebrew PCBs

Actually it would be less cumbersome, because you could see the drill
and not only rely on the camera.
Also you can do without the clamping foot for a top down drill.

When I built my drill stand I prepared it for an optical sight.
It is a top drill setup, and I was considering a simple projection
mechanism (think overhead projector) that looked on the board from
below. I experimented with a lens and some mirrors and I think it
might have worked.

Plan B was to use a small camera instead, if the optics didn't work out.

Turns out I don't need any optical sight after all.
