3 MOTIVATION I have always wanted a pinball machine. I enjoy projects and building stuff. I felt this would be challenging.

4 INTRODUCTION The earliest pinball style game was made around 1750 to 1770 The first real machine was manufactured in 1871 (WIKI) They were very popular in the 1970’s. To date, Sterns is now the only pinball manufacturer.

6 PROBLEM STATEMENT Pinball machine are a dying breed. There are few in existence for public use and most are in need of maintenance (i.e. the Indiana Jones machine on campus.)

7 PROPOSED SOLUTION To build my own full sized pinball machine. The initial goal was to use a microcontroller to run the mechanical parts. I needed to build a box to full size (26’x52’). I needed to order specific parts.

PROPOSED SOLUTION Software for this project was simple Just a few lines of subroutines was enough to get the needed data out. Circuit design was almost as simple. Playfield design was a difficult task. The playfield is large There were many holes that needed drilled The parts needed to be placed in a specific manner. 8

PROPOSED SOLUTION Testing was a step by step process. A lot of time was spent in checking the parts placements. This involved making sure that all solenoids actuated correctly. Also all parts had to be separated so that the ball could move smoothly 9

18 RESULTS I did not complete this project to my likings. Dealing with such large object is diffulcult. Include lots of images & relevant multimedia on (no dancing pink elephants) Well, maybe 1 or 2 goofy images in the presentation are OK

19 CONCLUSIONS Building such a large device is highly time consuming and it takes up a lot of room. More time was needed to completely make this project work as to my expectations and I just ran out of time.

20 FUTURE WORK I would like to add more to this project. Ramps, scoring, gutter lane scoring, and multi-ball are items of interest. I have not decided if I will continue working on it or tear it down.
