Why does this project exist?

Cheating is rampant in card games

Professional casinos often hire two guards per dealer

Shuffling and dealing introduce the largest possibility of cheating– Stacking the deck– Bottom-dealing

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)
