The Magic 8 Ball toy has first introduced in 1950. It answers yes or no questions via a 20 sided die floating in dark blue fluid - whichever side floats to the top is the "answer." In this project the die and fluid mechanism is replaced with an OLED display and Arduino based microcontroller.

Operation is identical to the original Magic 8 Ball - just flip the ball upside down and then right side up to get your answer (see YouTube video). You can edit or add answers of your choosing, and you're not limited to just 20 answers.

The modified 8 ball outwardly appears nearly identical to the original; there are no external switches, just set the ball down to turn it off and pick it up to turn it on. The ball twists apart to allow LiPo battery recharging or programming to add your own unique answers.
