Impressive mechanical calculation

Your Ad Here

This impressive machine is a calculator built entirely using the construction toy K'Nex. It was created by students at Olin College, US. It's more than ten feet tall (3.85m) and can add and subtract numbers from 0 to fifteen - that's four bits.

To make a calculation you need nine balls - 4 for the first number, 1 for the operation (add or subtract) and 4 for the second number. The whole process takes about 30 seconds, according to the builders "The slowest part of the operation is the user entering the balls".

If you want to know more about how it works, this page has animations that shows how the channels, funnels and baffles encode and process 0s an 1s in the form of falling balls.
