A small program build in BASIC. It was designed for solving the problem of shopowners of having to count all the tiny 1 Eurocent coins, when they close the shop at the end of the day before they go home.
Now, you simply weigh the coins, enter their total weight in the program and it will return the amount of coins. Unfortunally it's not finished yet, but you can download a free version that doesn't have the individual
weight of the coins set up yet. download it here.
