Automatic coin counter

# Automatic coin counter
## Intro
I did not found any coin counters, but can found good sorter. Simple china coin acceptors (616 or 916) can produce different quantity of pulses for each denomination. What if i use feeder of sorter?
I designed holder for coin acceptor that to be able to mount to feeder.
Also, i added bulge to rotor wheel to be able to destroy coins batches.
