Executive Summary
--Give two sentence intro to the project.
BeagleBall is a physical pinball machine, that will be controlled by a BeagleBone Blue. It will be a table top sized game.
Pinball Machine:
- 2 Servo Paddles
- IR object detection sensor to detect ball going through gap, score points
- Buttons to hit to score points
- IR object detection sensors to score points
- Play sounds
- either USB audio dongle and speaker
- or GPIO and buzzer
- 2 line LCD displaying score
- Constructed from plywood
Project Timeline
10/27
- Basic Plywood table cut and screwed together
- Code that responds visually and audibly (aplay) to button pushes
- Servos actuate on button press
11/3
- Plywood table coming together
- Buttons mounted on
- Servo paddles mounted on
- Has some obstacles and things
- Distance Sensor working and communicating
- Buttons to reset game
- Visual way of conveying score and lives
11/10
- Everything is done
- Everything mounted
- Things documented
--Give two sentences telling what works. The servo flipper work, however one of them stripped out the internal gearing the night before the demo. The buttons "work" however, the ball is not fast enough to provide enough force to actuate the buttons. The IR sensors work for both scoring points as well as detecting when the ball drops below the flippers.
--Give two sentences telling what isn't working.
I did not have time to get the sound working. I did not have enough GPIO to get the display working, and did not have enough time to reconfigure some the UART to be used as GPIO to combat this.
--End with a two sentence conclusion.
EDIT
The sentence count is approximate and only to give an idea of the expected length.
Packaging
- This was constructed using mainly plywood.
Installation Instructions
Give step by step instructions on how to install your project.
- Include your github path as a link like this to the read-only git site: https://github.com/maxcheese3/ECE497.git.
- Be sure your README.md is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
- Include a Makefile for you code.
- Include any additional packages installed via apt.
- Include kernel mods.
- If there is extra hardware needed, include links to where it can be obtained.
User Instructions
simply run "sudo python3 BeagleBall.py"
Highlights
It plays pinball! If you like pinball then this is the project for you. If you want to use it yourself you will have to create a physical pinball machine of course!
BeagleBall keeps track of your score, can tell whenever the ball is missed and goes below the flippers, has IR sensors and bumpers!
Theory of Operation
The program is written in python, and is pretty much just a running loop. It uses rCape to interface with the servos and has button detection events to detect when the ball hits an button or turns on an IR sensors, and when the user actuates the flippers.
Work Breakdown
List the major tasks in your project and who did what.
I worked on all tasks in this project. If I continue work on this project, most of the work will likely be done on making a new pinball table and getting faster moving servos.
Future Work
Faster powerful servos would be nice. A new table could be made based off what is wrong with the current table. If there was a way to get access to more GPIO pins, you could add more buttons and lights and a display!
Conclusions
It would probably be ideal to just ditch the whole idea of the flippers being controlled by servos and just rely on traditional mechanical flippers. Lights, sound, and a display would definitely be great additions.
