On our own time, we used some idea generating processes, like lateral thinking and morphological charting, to come up with some ideas. As a group, we started with listing off our favorite ideas and electronic components we wanted to use. We then drew all the ideas on a white board and found ways to logically put it all together.
We then went through two prototypes before landing on the final design.
Our first prototype was made using hand-cut cardboard and a lot of hot glue. It was very rough, and at that point we hadn’t figured out how to connect the Newton’s Cradle or the final inclined plane to the rest of the project. This was also when we learned how to use the tilt switch and LED, along with the servo motor that flicks the rubber band ball off the trash can.
The main goal for our next prototype was to correctly connect the two main sections of the project, with or without the Newton’s Cradle. We also wanted the next version to look more on theme, and this time we planned to use the laser cutter to create more precise pieces.
At this point, the prototype started to look much more like what we originally envisioned. All of the main physical components were in place, but we hadn’t added the second servo yet, which is triggered by the motion sensor to release the wheel and axle. This was also when we switched how the LED strip was activated. Instead of using a button, we changed it to a limit switch to make the system work more smoothly and automatically.
Our next goals were to make the project look more like the office theme we had planned and to make sure everything worked together.
