I can always use the BB for my original project and just use it as a learning experience before picking up Arduinos for the task.
I've got enough programming background to know the logic, but not necessarily the syntax. Dabbled in Python, C++, C#. (edit: Oh yeah, Javascript too. Evil language.)
As for electronics I had a Radio Shack 150 in 1 kit when I was a kid :P
I've hooked up an arcade button to the BB so far and made the LEDs switch on and off when I press it. That's a start :) I didn't see a cape (add-on board) for the BB to allow it to function as a USB device yet though.
The Arduinos already have an add-on that will do that, don't they?
Goals for the long term will be an A10-C, and a heli (although I haven't decided which yet).
