An MP3 player for 88 pence

I remember when mp3 players first came out. They weren't cheap. Now they are 88 pence. Brian showed me one at the Hardware Group on Thursday.

Going to the group is always a calculated risk for me, in that people frequently show me things that I want to buy one of. Mind you, at 88 pence each I can afford to go mad and order a number, so I've bought 5. 

They can be controlled by an Arduino (or any other device with digital I/O) or directly. You'll need a micro-sd card to hold the music and a speaker of some kind of course, but I'm thinking of using them to make an orchestra of Hull Pixelbots.....
