Final Project: Bluetooth Communicator

Since I am the type of person to sing in the shower, I wanted to design a mp3 player which I could take in the shower and sing to.

Before talking to Marlo and the TA's, I was thinking of making a waterproof mp3 player to bring in the shower. My design was based on putting all the components into a round waterproof tupperware to bring to the shower. I realized after talking to them that waterproofing everything will be extremely difficult, so I ended up trying to use bluetooth to connect to a bluetooth wireless waterproof speaker. The mp3 player can be in a waterproof case, and it can be left outside of the actual shower. 

 

Since I did not finish my project, I will list all the mistakes I made in the making of this project that made me unable to finish my project. 

1. I bought a part that was very hard to work with, when there was another alternate part that could have easily solved my problems. 

I had bought the bluetooth chip without realizing that I didn't buy the breakout board version. Soldering the bare chip was practically impossible, and that leads to my next mistake. 

2. I did not buy my parts early enough.

I had bought my parts too late. If I had bought my parts earlier, I could have bought the breakout board version of the bluetooth chip, but when I received the chip, it was already too late to order another part and make the project in time.
