Jiayang He is a student, she thinks some music players can be hard to afford. That’s especially true for ones which are small and compact, the price is usually pretty high. Take iPod as an example, it cost $149. Which is overpriced. This project lets you build an MP3 player/Camera that cost way less than that.
She got her inspiration from looking at her old bulky music player, which doesn’t have a graphical user interface either. The MPi3 will be a LOT smaller! And it also contains a camera as a bonus.
This is also a very good project to make if you want a portable device that you bring to school or work. Theoretically, it shouldn’t take too much power too drive.
