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
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
Card Dealer/Ejector
Two-tiered design Ejector servo or stepper
with flexible flipper to feed cards
Cards are fed to an accelerator (two vertically stacked wheels)
Accelerator “shoots” cards
Accelerator may spin freely (DC motor)
