I have build a wooden Pinball. Now I want to make it work like a real one! Counting points, displaying score and messages, making sounds...

Problem: pinball sensors are overly complicated and almost impossible to nicely integrate in a wooden pinball.
Solution: no sensor, just a Raspberry Pi with a camera which computes the position of the ball in real time, and then run all the pinball logic from that.

My goal is to make the software generic, so it can easily be adapted to any other DIY pinball. Only pinball logic and pinball layout mapping will have to be specific.
