That is really, really nice of you. I would be totally ok with the bricking risk, I have two blades that are no longer in use - one with a cracked screen.
The reason why I am so keen on this is that I want to hook the blade up to an arduino with some sensors, and leave it in my family's summer house over winter - to keep an eye on the temperature and play music when the mice are dancing. I know there are other connectivity options - actually got the blade to talk to the arduino using a 'host shield' over the weekend (through ADB, not Googles ADK), but it is not a straight-forward solution. Going to try a Bluetooth module as well, but would much prefer to use USB OTG. Currently using a Xperia Z for the project, where OTG works really well, but don't want to leave that in an abandoned house for half the year.
Ordered a Y-cable form eBay, but as the arduino has its own power supply it might work anyway.
