Currently CoinSorter only handles one size of coin at time with an off the shelf coin hopper. One should be able to handle mixed coin sizes with a series of independently driven conveyors controlled with an Arduino. Handling mixed coin sizes would make the system much more useful. For example it could find rare coins while doing the simple act of sorting and counting mixed change. This might involve some mechanical changes to conveyor belt guides and fingers or some electronic changes such as adding IR or eddy current sensors.
