1) new design of the MP3 player:
Parts ordered to achieve the project:
- Battery
- Charger
- Spare Arduino (which I eventually had to use)
- 8 Ohm speakers (x3)
- a 3.7V to 5V step-up
- 2 audio amps
Plan B:
- No duality loud speaker / 3.5mm jack (with auto switch from one to the other if the jack is plugged in)
- no bluetooth (the original MP3 player can stream music to speakers and can receive a feed and use the speakers connected to the circuit.
Project timeline:
- 08/01: order parts (done on 08/03)
- 08/05:
- Solid works drawing finished (done in time)
- barebones MP3 from lab 6 up and running (done)
- 08/07: box cut (done on time for the MP3 box but not for the speakers. Boxes for the speakers were done on 08/10)
- 08/12: add new components (speakers and momentary buttons used as controls and switch for general power)

✓ Is this the design and plan B that you had in mind as of week 5/6, or the redesign(s) that you worked out retrospectively?
