Would love to see a tutorial or source code in the near future. Also, that is quite intriguing you can use one along with the bfgminer API. I may look into implementing one with my raspberry pi.
Agreed. This might be a better solution than my raspberry pi with screen.
Would also love to see some tutorials, or at least some documentation on how you did this. Anyone know where I can get a cheap one? I'd love to dev and play around with it.
