Project Description Automatic shuffling and dealing of a standard 52-card deck Deal for several different game types Rotates to a player’s position and deals cards

Project Description Three distinct components: – Shuffler/Rotating Base – Card dealer/ejector – User Interface/System Controller Size: ~8” wide x 5” deep x 12” tall Weight: Between 2 and 3 lbs.
6
Shuffler/Rotating Base Standard store-bought card shuffler Rotating base a stepper motor – Fastened to the shuffler base – Can rotate sufficient weight to turn card dealing mechanism
7
Shuffler/Rotating Base Needn’t rotate 360°, so tangled wires not an issue 160° arc allows for 8 players evenly spaced 3 steps of the motor apart Only deal to those positions and only if UI control is activated
