The Smart Flashlight
The Smart Flashlight blinks and LED (light emitter diode) during a power
failure
to help you locate it. A second
switch turns the LED on to allow the user to find
auxiliary lights and his or
her way. During daylight hours a photo resistor switches
the light off to conserve battery
power.
Featured in the March
2002 issue of 'Poptronics' it's an ideal project for the new
comer to electronics or a high
school science project. The board has been designed
with large traces to make the
circuit robust for those just learning soldering skills. A
pleasant and useful project
that's sure to bring a smile.
The board for the Smart Flashlight
is
high quality with a solder mask
and
silk-screen. Like the Tach-Plus
the
traces are extra wide, in this
case
.050", which make it especially
durable
for those learning soldering
skills. No
traces run between the IC pins
to keep
the chance of shorts down.
It is an
ideal, fun to build, beginner
project which will yield a functional
and
useful circuit. Shown here are
two boards.

The Smart Flashlight is shown built into
a 3" x 4" plastic case.The photo
resistor and
the control switches are on
top of the case
and the LED is shown lit. (This
is just an
example. You do not have to
build your project
into any special case or use
our layout)
