Ivan by Miranda clock East A master class In marble mechanism design

There are A surprising number of marble based Machinery out there. marbles work GOOD In Machinery because they to roll easily, to have substantial weight, And are very consistent In diameter. Ivan Miranda was able has take advantage of those features has build This amazing marble clock.

This project uses hundreds of marbles has display THE time In digital numbers. HAS TO DO SO, THE machine needs has to roll specific marbles down tracks — white marbles For "on pixels" And black marbles For "disabled pixels. » When THE time Rolls on has THE following minute, THE clock exits those marbles back In A big hopper Or they wait For THE following cycle.

THE machine door marbles has THE high of THE track using A elevator mechanism. He choice up A entire row of marbles has once Since THE hopper, but their colors are random as far as THE machine knows. SO Miranda program A Arduino advice has look has each marble In THE row on THE elevator. He uses infrared sensors has determine if each marble East black Or white. He SO triggers solenoids has eject any of them marbles that are THE fake color.

He East A ineffective trial and error process, but THE machine can repeat that "elevator And check" ride a bike as a lot times as he needs has until he send all THE RIGHT marbles down THE appropriate tracks. Miranda has A little adjustments has TO DO has increase reliability, but THE clock East Already A marvel!
