The Brain Board/Wozanium pack web page is up and includes a link to the Beta Manual with has all kinds of information about the implementation. I have a little more to add, including an example downloadable driver that allows a user to control the machine through a super serial card.
I have had some good feedback from the Beta team. Several improvements have been made to the Wozanium firmware and will undergo testing this week. I plan on starting general shipments on 3/21/2011.
Cost for kits will be $59 with free shipping in USA and $10 shipping internationally. I also plan on offering built up units, once I get through any flurry of initial kit orders. Send me an email, if you have any questions.
