The Marbelous Bells is a music machine inspired from the Marble Music Machine by Wintergatan (look it up on YouTube, it's amazing.) The machine works by turning the crank which turns the program wheel. The pegs connected to the program wheel will hit a hinge that will pull a string. That string will pull on our "Kerchink", and that will release a ball, but hold the rest. When the pin moves away from the hinge everything will reset, and the next ball to drop will be in place. The ball will drop onto one of the notes, and all the notes together will make a song. The "Kerchink" is a small mechanism that is made of two metal pins, a spring, and small wooden pieces with tiny metal rods. The two pins are stack on top of each other with a small space, the spring is located on the bottom pin, and the other wooden pieces/metal rods hold it all together. When the bottom pin is pulled out by the string, it drops the ball, but the top pin is pushed in by this effect and so it holds the ones on top. The spring pushes back on the bottom pin to release it out and to get the next balls ready.
The video below is the inspiration for the project, this Marble Machine was musically invigorating and mechanically challenging, but it was a beautiful piece of artwork either way. Once finishing the video, I wanted to use that as my maker faire project at my school. I didn't want to building it the same way he did, his took years, plus buying all the instruments is expensive. So the design was simplified, but still amazing.
