My pinball machine is built on a rectangular ”plate”, where there is made room to mount the ”feet” on the sides. I got the inspiration for this from Mario Ferraris homepage. After that it was only a question of making appropriate obstacles on top of the ”plate”. The program itself is written in LeJos and, besides keeping track of the score, it also generates a high score list. If you are good and make it into the top three, you can enter your name using the buttons on the RCX.
