This is the kind of initial prototype I dont have the model a+ setup yet I was previously using a old model b and had it working great but had to be controlled over the network I need to make some software and add buttons.

I have to use a usb sound card because the sound onboard the raspberry pi isnt as loud as I like. A problem I ran into is the a+ only has one usb port so cant connect wifi, sound card, and sdxc reader without a hub.

I think I will make two versions of this one that uses off the shelf components ie rasbperry pi or im also looking into odroid but also another project using any old cellphone running android found off ebay the reasoning is they are small come with wifi and decent sound built in also a battery for the 5th battery like I want.

I wiill work on the software for the buttons and get the model A+ working in the next few days and post another update!
