Hi All, I just wanted to let those interested know that I did settle on an Arduino board for prototyping my project. I choose it for several reasons; off the shelf hardware (mp3 player expansion), FOSSish in nature, and what sounds to be a relatively short programming learning curve. I'll keep notes on the project progress on my blog, updated once a week or so, at http://www.classicmagicstudios.com/wordpress/?cat=17. Thanks to all who responded and helped me decide on the Arduino, Kyle Eric Wetzel wrote: > On Thu, Jun 17, 2010 at 5:49 AM, Kyle Winfree <kyle.winfree@gmail.com> wrote: > >> Hi Tom, >> Have you ever done any audio projects with either?
