The Bola 8, or more commonly known Magic ball 8, is a project based on the hackaday posted project
It works by having a tilt sensor conected to the clock input of a decade counter. Each output of the decade counter is conected to an led, that neben it has a text that predicts your future.
The project can be edited to have your own personalized predictions (Just go to the pcbEditor of Kicad, and change the values of the text).
Componets BOM
And of course, the leds are separated at the same distance (for those who have OCD ;)) To make it work, just press the button, and move the Bola 8 up and down, while you make a question

Questions
How big is the Bola-8 PCB?
It measures 22 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bola-8 use?
20 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bola-8 KiCad files?
From the aetel/Bola-8 repository on GitHub, at the commit this page was made from: the board is bola8.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bola-8 design in my own project?
Its repository states no licence, so its author keeps all rights: ask aetel before reusing the design.
