Entropy Dice - Máy lắc xúc xắc tự động

This is a automated dice rolling machine, it rolls three dice in a tube and reads the result with OpenCV, Python on a Raspberry Pi 5.  Equipment used:

• Raspberry Pi 5

• Pi Camera 2

• DRV8825 stepper driver

• NEMA17 12v/0.22NM steppermotor

• 50mm clear circular acrylic glass window

• Screws, M4 and M3 of various lengths.

• Wires for connecting electronics

Software is programmed in OpenCV, Python. System works by using blob-detection to find dots, and grouping the dots to dice with dbscan. Three dice are used, but with a bigger tube more can be measured at the same time.
