how to make an rpm guage that is accurit and take samples in
1000 ms or less and tell the rpm out as 1 to 2200 rpms with the
resultion of 1 rpm.
I thought of ways that work at low rpms but dose not work at high.
Im using an black and white striped disk glues to a 2 in fly wheel.
with 60 strips.
The only thing i thought of is to make a flip flop circut to clean
the signal up.
but can the BS2 handle that many pulses?? at 2000rpms that
120000 pulses a second.!!
Thanks
