The power and signal pads on the PCB conform
to the FuzzDog Direct Connection format, so
can be paired with the appropriate
daughterboard for quick and easy offboard
wiring. Check the separate daughterboard
document for details.
Be very careful when soldering the LEDs, diode
and LDR. They’re very sensitive to heat. You
should use some kind of heat sink (crocodile
clip or reverse action tweezers) on each leg as
you solder them. Keep exposure to heat to a
minimum (under 2 seconds). Same goes for the
IC if you aren’t using a socket.
Snap the small metal tag off the pots so they
can be mounted flush in the box.
We’ve placed C9 on the rear of the PCB. There’s
no need, but it does go into dead space on that
side rather than potentially getting in the way on
the front.
Mounting the LEDs and LDR
The original spec for this was for the LDR to
face the tops of the LEDs. We’ve tried it like that
and also with it simply facing the side of them
as shown in the front cover image. We couldn’t
tell any difference. If you’d prefer to go with the
original spec just bend your LDR accordingly.
See below.
The circuit won’t work unless it’s light-tight, so
you’ll need to cover it while testing. Once you
mount it in an enclosure you’re good to go.
