Design a product prototype

Completed Posted 7 years ago Paid on delivery
Completed Paid on delivery

I need a prototype with the following parts: an array of up to six momentary switches, and array of up to six small microphones, flash memory, a processor, and a micro or mini usb port. The unit should start recording when any of the switches are pressed, record for 30 seconds, and save the file to memory. The files would then be retrieved by connecting to a computer through the usb port.

I would like a physical prototype, parts diagram, and the code. This should be a functional prototype, it does not need to have a custom pcb board. It also does not need a case, I will build the case.
I would like it to emulate a media storage device and store the recorded sound as a file type that most windows computers could play, such as mp3, wav, wma. The audio file does not need to be high resolution, mp3 quality is adequate.
