Planning & Execution
Table of Contents
If you would like a brief rundown of the project requirements, the Project Summary can be downloaded as a PDF here. This gives a more specific definition of the intricacies involved with this project.
Traditionally, electric guitars have used electromagnetic pickups, which detect changes in an electromagnetic field caused by the vibration of metal guitar strings. The objective of this project is to create a product which can be mounted on a guitar, and by opto-electronic means, amplify a string movement from the guitar, and output a signal. Also, two types of filtering, both digital and analog, will be provided.
Objectives relate to tone detection and tone quality,
along with mounting flexibility, being fully removable
from the guitar. Variation in string movement, player
hand positioning and environmental interference make this
project a bit of a challenge.

Intellectual Property Considerations
Because of the availability of patents online, we were
able to verify that patents already exist for optical
instruments. Two relevant examples follow:
There is also a patent on coaxial mount sensor system as well.
So most likely, we will not be setting any goals to achieve patent rights with content in this project, nor will we be use these patents to steer our project, as they seem to focus on integrating the system into a specialized guitar.

Team Norms & ValuesTeam behavior expectations
It is our expectation that there will be a team wide distribution of work, regardless of expertise, and that work will keep a constant forward pace.
To maintain a balanced work distribution, we will keep open communication between team members and prevent stalls in progress by reaching out to each other for help.
Roles and responsibilities
Roles will be based on volunteers for the position and consensus agreement.
Honoring the strength of individuals
Individual knowledge in specific fields will be recognized and allowed to drive progress for specific tasks.
Interactions with guide
Interactions with the guide will be through the project lead.
Communication with one another
We will try to maintain as much person to person interaction as possible, but will also make use of email and messengers to communicate.
In most cases, decision making will be based on consensus. Majority vote may be implemented during rare cases of disagreement.
Expectations for integrity or responsibility
Members will respect due dates and finish assigned projects in a timely manor. If problems arise, early and clear communication for help on the task must be sought.
In the cases of a conflict, team members will try to work it out individually, or with the project lead. In more difficult cases, outside counseling may be sought.

Meeting Minutes, Notes, & Actions
Preliminary Design Review Notes
I. Dr. Patru (Customer)
- Double check spelling in documents and on EDGE
- How are marginal and ideal being defined?
- 110 Hz is the absolute cut-off frequency for the amplifier. The ideal range for our application is (inclusive) 125 Hz to 20 kHz
- Ensure the output signal from the sensors is strong enough to not be impacted by external factors such as noise should we choose to implement the XLR configuration. Prove by numbers that this works or does not work.
- Solid fixture as a filtering mechanism?
- Use less solution specific terminology in the brainstorming list (e.g. discrete components instead of transistors)
- The term “analog filter” is too generic. Be more specific.
- Eliminate back-up batteries from power supply list. Also, on/off is a function, not a solution.
- Sensor configurations 3 and 4 (diagonal and reflective) should be tested
- Budget is firmly set to $500, so do not be concerned about cuts
- Rephrase items in system diagram
- Begin the system design: Devise tests and start ordering any necessary components for testing and data collection.
II. Les (Guide)
- Capture sound measurements and add the data to EDGE
- Still mixing certain items in the functional decomposition. Remove output variables and solutions from the decomposition.
- Brainstorming list needs more specification as it is too generic
- The brainstorming list needs to be less solution specific
- Optimizing parts won’t optimize the entire system. Consider one solution at a time in the Pugh charts.
- Investigate filters further
