Objectives

As a group, we realized through systems engineering we have little experience with modeling and 3D printing. For this reason, we decided to take this class and spend the semester learning and constructing a desig n and model to be printed using a 3D printer. We were thinking about different products that are interesting to us and would want to use in our daily lives. All of us have come across the problem before where we're trying to play a video or song from our phones, but the volume is not loud enough for everyone to hear and we do not have a speaker with us at that moment. We came up with the idea of creating a case for our phones that also doubles as a portable speaker.

Challenges

• User safety: The wires and jumper cables were using to connect the phone to the speaker cannot shock the user
• Phone safety: We can't send too strong of a current through the Aux cord and 'fry' the user's phone
• Privacy Considerations: The speaker cannot be too loud, in order to be considerate of others
• Learning arduino and how to code a display
• Learn how to use Fusion260 (Autodesk) and how to design a functional model to be 3D printed
• Figure out how to amplify sound from the headphone jack using an Aux cord and build a simple circuit connecting it to a speaker
