Introduction
Introduction
Data was collected two separate times (with the exception of the flashlight test) through a series of tests. Each test was used to determine how well the prototype aligned to our design specification (see element H for more information). The data from the two different times was then compared to see if our prototype improved between revisions.
The Flashlight Pass/Fail Test

Analysis
Analysis
The flashlight pass/fail test provided us with insight of how the generator would connect to the door mechanism. Although the flashlight never actually turned on, we were able to see that the flashlight's gear was turning, meaning that the door mechanism would be compatible with a generator.
The Force Test

Analysis
Analysis
This test indicated that the prototype would not impede the normal functioning of the door as 5 lbs is considered the acceptable maximum force. This test allowed us to focus on other aspects of the prototype more related to electricity generation and consistency.

Analysis
This test confirmed that the adjustments we made to make the prototype more consistent did not impede the function.
The Voltage Test
The Voltage Test

Analysis
Analysis
This test confirmed that the faster the door was opened, the more electricity would be generated. It also confirmed that there would be enough voltage for our circuit assuming the door was opened in 10 seconds or less (0.2 V minimum). Changes, such as adding another magnet plate and adjustments to the gears, were made to allow the prototype to generate more electricity more consistently.

Analysis
Analysis
This test indicated that the adjustments we made between the first and second prototype allowed it to generate more electricity. The data was also used to determine the necessary number of capacitors for the circuit.
The Safety and Durability Test
The Safety and Durability Test
Analysis
Analysis
This test determined that at certain speeds, our prototype would lose efficacy over time. We attempted to solve this issue by adding another gear next to the first gear on the track of our door mechanism. We also stabilized the axles and switched the material that held the generator to the door mechanism from vex parts to wood.
Analysis
Analysis
The retest allowed us to determine that the adjustments we made to the original prototype worked to some capacity but more adjustments should be made in the future to ensure a reliable prototype.
