[sjm4306] had a small Magic 8-Ball key chain as a kid. The fluid in this key chain eventually dried up, and if [sjm] is anything like us the 20-sided die is now lost to the sands of time or at the very least hidden in a box in the basement. After remembering the old Magic 8-Ball one day, [sjm] decided to build a digital version of everyone’s favorite bewitched billiard ball.
The digital magic 8-ball uses a PIC16f886; more than enough to hold the twenty possible replies from a real magic 8-ball. The display is a tin 3 cm OLED which surprisingly emulates the ‘icosahedron with raised letters floating in purple liquid’ aesthetic very well.
Right now, this is just a breadboard prototype – there isn’t an accelerometer or tilt switch in the build yet, so shaking the project does absolutely nothing. [sjm] may add that functionality later by turning his project into a watch, key chain, or installing it in a real Magic 8-Ball case.
