Coin Feeder Machine Prototype

Video above shows concept to distance coins and control flow,. Hopper allows to deliver say 1 coin when machine request 1 coin, design prevents any jamming and allows smooth flow of coins so exact count is dispanced. Sorting gear can be controlled by open loop servo or even regular motor. 3 sensor positions can be added to detect if there are no more coins in line (ex Add more coins error message), coin ready sensor, and coin sent status so we know coin was delivered to next module for processing. In case of rim engraving project next module would be fixture that will hold coin to chuck.
