crimp. Each crimped LED should
look something like
way over the surface of the wire
mesh, making sure that they all face
outward.
mounted on the metal mesh frame. Measure the distance that the LED
frame will be from the control PC and LED driver circuit boards. Cut 19
pieces of CAT5 wire to this length, plus 10 feet.
CAT5 bundle. Since each bundle has eight wires, this bundle will require
three lengths of CAT5 wire. Grab one wire for ground from a shared-
ground-only CAT5 wire.
dered to DB25 connectors, label
each bundle and lay it out on the
floor next to the LEDs and wire
mesh. Solder each wire to the long
leg of each LED, and seal the LED
and wire in hot-melt glue according
to the diagram in
at a location where there is more
than one wire of the mesh to secure
things, and use a small wire tie to
ensure that nothing moves.
es: it insulates the drive wire from
the wire mesh (which is ground),
and it holds the LED in place. Before
the hot-melt glue cools and hardens,
make sure that the LED is facing
upward and that the solder connec-
tion between the long LED leg and
the drive wire does not touch the wire mesh.
