Getting Real - 3
Again, the holiday projectors turned out to be the solution. It
was an easy matter to remove the light and socket from the
rear of the housing. I then purchased several second-hand
strobe flash units on eBay. I used my table saw (a hack saw or
any hand saw would work as well) to cut a slot in the back of
the holiday projector
housing that the strobe
light would fit into.
The next challenge was
to find a way to coordi-
nate the flashing of the
strobe light with the
flashing of the super-
bright LED on the circuit
board. To do this, I pur-
chased several strobe
flash "slave" units.
The device consists of a small
box with a cord that plugs into
the flash. It senses the flash of
light from a nearby strobe light
and triggers the device that
it's plugged in to. I then taped
the slave trigger device on top
of the super-bright LED. Now
every time the super-bright
LED flashes, it triggers the
strobe light. The strobe flash,
trigger and circuit board are
all enclosed in a plastic elec-
tronics project case, attached
