Printing equipment such as sheet-fed presses refer to speed in
impressions-per-hour. I want to build a circuit that will display this number
on 5 LED digits.
The sensor will be a simple hall-effect or other sensor that is triggered up
to 4 times a second (maybe less than one, probably not more than 5).
It's a simple thing to start and stop a timer to calculate the period of the
print cycle, but how to convert that to a meaningful IPH figure? Is a look-up
table or maths done by microcontroller the only way? Or can some other means
be used?
I prefer the non-microcontroller solution, as I haven't yet broached the PIC
[used as generic term] world...
Thanks,
