Kerm: Looks amazing, what's the estimated cost of materials?The Spark Core itself is $39, and the only extra hardware that you need is half of an I/O cable. It would probably cost an extra $20-$30 for a battery and charging/regulator circuit, depending on what you used. I'd love to create a standard board that the Spark Core can slot into that also has an on-board charger and regulator and socket for a LiPo, but I doubt a lot of people would be interested in purchasing it.
Also, keep in mind the Spark Core is open source design, and their site claims that actual parts are only about $15 if you have them made for you on a larger scale.
