Hi, i'm trying to build a display screen headphone similar in shape to "vizio's LCD headphones" shown at CES 2010, but different in function. The display screens on the headphones i want to make have only one function: to show what music the user is listening to. For example if i am listening to a Michael Jackson song, the display screen will be able to show: the name of the song, name of the artists or the album art of the song i'm listening to. My question is about the design of the motherboard. It will need to house a 50 by 50 mm LCD screen, a Bluetooth chip (for receiving song data), a microprocessor and a power supply chip. Can you give me advice about what shape and size the motherboard has to be?
