Hello,
        I'm in the middle of designing a device that is going down into the
deep, dark ocean. It's just a little quadrature encoder that is going
on the end of a robotic arm to measure the revolutions of a torque
tool. The problem I foresee is driving the LED's to really make them
shine. Is there a device like the ULN2803 that I could use to drive
the LED's to something higher than 25ma ?? The LED's are rated for
30ma and I figure I can pulse them at something higher i.e. 50 to
60ma. Of course I could do it with transistors but an IC would be
more sanitary. I've been to all the local electronics shops looking
for the 2803 or something like it. I've pulsed some IR LED's to 2 A
with no adverse effects therefore I assume you can drive regular RED
LED's at something higher than rated current. Any ideas ?? All help
is appreciated.

        Thanks in advance !!
