Digital Dice

thingiverse

This is a PCB file for milling a circuit board (pcb) in a Digital Dice Project. Using three AAA batteries, it will display all die combinations when you press and hold the push button switch. When you release the switch, it will stop on one of the die face combinations. It is designed using a 555 Timer, a 4-bit counter, and some logic to convert binary to numeric equivalent for each die face. The STL file for the 3D-printed pcb frame can be found on my Thingiverse page.
