Atr user, posted this week at Eurobricks a Pinball machine he made based on NXT.
Is is not the first working Pinball machine machine made with LEGO, but I still liked it a lot.
In the author's words: "Pinball machine uses one NXT Brick, 4 touch sensors (3 of them are attached to one port) and 2 light sensors. Program is written in Java (LeJOS). After pressing orange button the ball is given and a new game is started. Every game has three balls total. If the ball is lost within 10 seconds after start, the ball is returned without losing one."
Even there is a description about how the points are collected.
- losing ball after 10 seconds - 50 points
- hitting both Red and Green Bumpers - 100 points
- hitting one of the Yellow Bumpers - 200 points
- getting ball to the Black Hole - 300 points
Black Hole opens up every 500 points, then player has 20 second to get the ball into it. If 5 seconds is left Black Hole's light starts flashing.
It is really awesome and worthwhile to see! It looks the playing experience is also really nice.
