To create the physical device, we used a combination of fabrication and electronics. The box was laser-cut from a white acrylic board and stuck together to create a sense of minimalism and futurism of technology. Two springs with a holder are added to the base of the box to create a mechanism for users to toss the coin. Inside the box, including an Arduino microcontroller（Arduino Nano BLE 33, and an Adafruit LCD screen. 

The user simply tosses the coin six times inside the box, with the left side of the box colored white to represent Yang and the right side colored black to represent Yin. The machine will analyze the results of the coin tosses and provides insights into the user's future based on the hexagrams of the I Ching.
