Challenge: Construct a Distinctive Coin Sorting Device
Challenge: Construct a Distinctive Coin Sorting Device
Overview: You are tasked with designing and building an original coin sorting system that can accurately separate U.S. pennies, nickels, dimes, and quarters. Your solution should demonstrate both technical proficiency and creative thinking, resulting in a device that is unlike existing commercial products.

Design and Assembly
Design and Assembly
Circular disk for different coins to fall into
Cut with lazer
Active cut
Fly wheel to sort coins
Both components, post cut, combined to create sorting subsystem
3d printed hopper: coins fall in to be sorted
Design in SolidWorks
Base for collection
Collection system- each type of coin has it's own section
All parts connected- motor attatched to spin
Hopper Inserted- surrounded by cardboard
Motor Batteries
Base for Collection
Measurement of product- 12 inch constraint
Spinning System
Final Test
Conclusions:
The coins are dropped into the device while being timed with a stopwatch in the bottom left. Sorting the coins at a small quantity with 100% accuracy in a time of 6.91 seconds (although only 4 coins managed to fall through without getting jammed.)
