Homemade mechanical pinball

My homemade pinball machine. It was made from junk. The flippers work mechanically. The upright contains an old Dell LCD-screen. The sensors are hard wired to a keyboard, that is connectet to a Flash.swf for the display. It has singleplayer, high score, and it keeps track of number og balls left. The sensors are alle constructed of welding wire, which the ball will connect. Two of the sensors have their own ball, to ensure a more secure connection.
