Hello Chad,
That talking strobe system was designed my me in the mid 90s. I am
impressed it has lasted for over 10 years. It is the oldest unit in the field.
Send it back and I will repair it for you. Let's see if it can make it to 15
years.
You must have tired of my voice. I wonder how many times I counted down to
zero in ten years?? I am sure there is a record of some kind. I am curently
considering using the new high power blue LEDS for the light source for a
new type of shadow wall. By varyng the pulse length of the source,
interesting shadow effects would appear on the wall when the children where
in motion.
