DroptheBeat is my teams final project for Principles of Engineering, and one of the larger projects I have ever undertaken. Over the course of 8 weeks my 4 teammates and I manufactured a machine to play music by hitting 1/4 inch ball bearings against tuned metal pipes*. as you can see from the diagram below this was a wildly complex project that I am not going to go into here. Instead I highly recommend you checkout the project website found here. I highly recommend at least checking out our home page, there are some really cool graphics there. 
*Only 300 bearings were lost in the production of this machine and we only spilled all of our 2000 tiny metal balls and had to pick all of them up a couple times.
