Homebrew PCBs

An xacto blade works but you can also build a circuit blaster from a
large capacitor, dc supply and a couple of probe points and a foot
switch.

Put the probes on two parts of the trace and hit the foot switch and the
trace is gone. I built it for cutting inner layer traces on 6 layer
boards.  You need enough energy to do in the trace without causing a
carbon tract.  I limited my voltage to 5V so as not to damage and IC's
on the board, that's  a little harder to day with 1.8V parts.
