Home Made Gravity-based Coin Sorter

The basic structure is made of cardboard, and put together using glue. In order to create the variable rule that guides the coins, I used little sheets of plastic. I placed the sheets of plastic in a tile-like structure, so that each one overlaps with the one above it. This design allows the height of the tiles to be adjusted conveniently. This coin sorter sorts 6 categories of coins. One way to optimize the sorter would be to separate the coins into the smallest 3 coins vs the largest 3 coins, and have each group of 3 be sorted separately. This would allow more coins to go through, but of course the structure would be much more complex.
