Homebrew PCBs

I clamp the top edge.

The clamp is made from two plastic (or FR4) plates, pulled together
with a rubber band (piece of bicycle inner tube). To open the clamp
there is a titanium rod, flattened on the end, inserted between the
plates. The rod is twisted with a lever to pry them apart. The trick
with this is that the rod exists through the top of the clamp, which
is mounted to the lid of the tank, which in turn allows me to actuate
the clamp from outside the lid with just one hand, without getting
said hand dirty.

You waste a small strip of PCB at the top edge, but that doesn't
particularly concern me.

Remember that you can not use most metals except titanium.

The fishing line may very well be problematic if the PCB is pushed
against the side of the tank by the bubbles/current.
