Team Vision for Subsystem Level Build & Test Phase

In this phase of MSD2, the team worked on implementing test plans developed in previous phases, and troubleshooting any problems with current designs. The test plans were meant to provide a means of confirmation as to whether the new designs were successful.

Phase accomplishments:

Test Results Summary

Summarize test results and assess effectiveness of test plans to unambiguously demonstrate satisfaction of the engineering requirements

Power Block

  1. The power module needs to be connected to the battery input, or an equivalent voltage from a power supply for testing purposes. This converter is configured based on external component references. Since our LEDs and proximity sensor demand five volts and the microcontrollers can handle that input voltage, the output of the converter needs to be a fixed five volts regardless of input voltage as the battery voltage changes depending on charge level.
  2. Connected board to power supply, and the output voltage was not what it should have been. Since the boost converter operates at 2MHz, any small defects in how the board was fabricated can cause subtle errors to be amplified and cause errors.
  3. Since we are short on time and budget, a small pre-made module board was used which contains the same converter chip that was used in the schematic. This module can output the correct voltage and will be used for further testing and design work.

Voltage Controller and Battery Tests

Speaker Tests



  1. Quantitatively summarize the capabilities, performance, throughput, and robustness of your subsystems as demonstrated by execution of the text plan. Document your testing with photos or videos in addition to test data.
  2. Evaluate how well the test plan was able to confirm satisfaction of subsystem requirements
  3. Include snapshot of testing completed to date, and include link to live requirements and testing document
