1j. For the potentiometers,
use the 7" bit to enlarge the
holes at ( 1, 6), ( 1, 10), ( 26, 6),
and ( 26, 10). Locate pin 1 on
each of the pots; it’s the right-most pin as you face the pins
with the pot shaft pointing up.
Fit the pots’ mounting tabs
into the enlarged holes with
pin 1 of one at ( 4, 9) and pin 1
of the other at ( 23, 7). Solder
into place.

NOTE: You’ll solder the
pushbutton to these 2 loose
wires after fitting it into the
front of the panel.
1k. For the programming
socket, cut 3 wires, ideally of
different colors, about 3½"
(or 9cm) long. Solder one
end of each to ( 1, 11), ( 1, 12),
and ( 1, 13). Remove the 1"
stereo jack cover, slip it over
the 3 wires, and solder the
wires to the jack’s contacts
for the plug’s sleeve (inner),
ring (middle), and tip (end),
respectively. Replace the
cover.
1l. Solder 2 wire leads for
the pushbutton about 7"
(or 18cm) long at locations
( 1, 14) and ( 1, 15).
1m. Solder 2 wires about 7"
(or 18cm) long to the PCB at
( 26, 12) and ( 26, 14). Solder
the other ends to the panel-mount mono audio jack’s tip
(signal) and sleeve (ground)
contacts, respectively.

1n. Solder the 9-volt battery
clip to the board, red (+) to
( 1, 2) and black (–) to ( 1, 4).
1o. Plug the Picaxe 08M into
the IC socket with pin 1 at
upper left, nearer the LEDs.
