Criteria and Constraints
Criteria and Constraints
Criteria:
Must sort pennies, nickels, dimes, and quarters with 100% accuracy.
System must have a vibrating hopper system. The system will be provided (switch, battery case, and motor)
3D printed parts can be designed, printed and utilized in the system.
Recommended construction materials (cardboard, foamboard, duct tape, hot glue gun)
Creativity is required. Your system must be unique in someway.
Constraints:
The system cannot take up more space than a 1ft squared.
Must be completed within a specified time.
Materials cannot be purchased.

These two are images of the actual bottom of the sorting device where the coins fall through and then the hopper design.
These two are images of one of the boxes to catch the coins and then what the final product in CAD looked like.
Laser Cut Pieces
Laser Cut Pieces
These pieces include the triangular structure for the back piece, the walls for the chute, and the holes/barriers for the coins
Post Processing Cut Pieces
Post Processing Cut Pieces
Pieces being cut out on the Laser
After laser cutting and scanning the pieces for the coin holders, we assembled two sets for maximum sorting speed
In order to create a consistent angle at the top of the separators, we cut them in individual pieces (11 each) and glued them together

Attaching The Motor and Hopper
Attaching The Motor and Hopper
This is our final revision of the hopper with the motor attached to the back.
This was a first attempt at the hopper. Ultimately got changed because the motor wasn't strong enough to make it vibrate well.
This was where I was soldering the motor wires to make the motor actually spin.
Testing
Testing
Accuracy? Not great.
Speed? Wonderful.
Potential improvements: smaller slope, larger hopper, smaller tolerance on hole
