going until you are done.
RadioShack sells a very nice “Nippy
Cutter,” which is excellent for trimming component leads. Remember
to leave enough lead to solder to
(about an 1/8 inch) and be sure that
adjacent leads aren’t shorted to one
When you are ready to connect
the board to the front panel, it’s a
good idea to do so in a manner that
will let you fold (and unfold) the
board under the front panel easily so
that when you want to modify or
troubleshoot the project, it will be far
more convenient to do so. A little
extra length on the wires from the
panel to the board will translate into
a lot less frustration later.
Figures 8 and 9 show the points
that get connected together.
Connect the labeled circuit point
from the board to the
front panel point with the same
label. Again, measure the wires and
install them one at a time unless two
wires go to the exact same point.
I would suggest approaching the
project in the following phases:

• Gather the components.
• Etch and drill the circuit board.
• Drill and label the front panel and
make a case.
• Populate the circuit board.
• Populate the front panel.
• Wire the front panel to the circuit
• Go make some cool sounds.
