Usb to audio out adapter?
Some stereos now have female usb sockets built into them to play music from a memory stick. Mine does not, which is why I am looking to make/buy a usb to 3.5mm audio out device that can read the files on my memory stick and output them as audio. I have done a concept picture using professional editing software 'Paint', but the sd card reader is not really that necessary. It could also be battery powered, the picture is just a basic idea of what I want. I have spare computers I could raid for parts if I need. Any help would be appreciated either building or buying such a device, but low costs for both are a big need.
