OLED Magic 8 Ball has attitude! #FLORA

NewImage

Thanks to Paul for sending in his awesome Magic Eight Ball project! Check out the full build at Instructables.

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.

The circuit is very simple consisting of just 4 parts: OLED display, Flora (Arduino based microcontroller board), LiPo battery, and orientation switch. The toughest part of the project is neatly cutting the Magic 8 Ball, so step # 3 provides detailed instructions.

Monochrome 1.3″ 128×64 OLED graphic display: These displays are small, only about 1.3″ diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128×64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! Read more.
