Community Hall of Fame Pick: Magical Marble Sorting Machine

How to keep 'em guessing!

April 20, 2015

The sight and sound of Alex Pikkert’s newest creation, the Magical Marble Sorting Machine with its symmetrical design and glitter painted marbles, is a delight for the senses.  The best part is it apparently sorts marbles by color!

Each time Alex pushes a button on the lower level, a servo kicks a marble out of a copper wire storage ramp into the marble selector tunnel.  After a moment of secret happenings in the tunnel with a pink mystery bit and the Arduino module, the marble is sent on a trip around the MDF wood marble transport disk until it is kicked off by a servo into a bowl with a pleasant plink sound.  Let’s watch it again and again!

Alex promises to reveal the mystery bit and Arduino code soon.  He is waiting for someone to guess correctly, so leave a comment on his project with your best guess as to how it works!
