Steam Controller: Open and Hackable?

http://hackadaycom.files.wordpress.c...pg?w=580&h=419
The folks over at Valve Corporation have been busy. Just this week they have made three announcements regarding the future of their company; SteamOS, a linux-based operating system, Steam Machines (for running SteamOS), and the one we’re most interested in, the Steam Controller, an open controller. Not to worry though, the controller is not exclusive to the Steam Machines!
This is why we’re intrigued:

The Steam Controller was designed from the ground up to be hackable … We plan to make tools available that will enable users to participate in all aspects of the experience, from industrial design to electrical engineering.

We’re curious to see what that exactly means, but it definitely sounds promising! We know that Valve already takes in tons of customer feedback through their Steam Community and Workshop contributors, but how open is this controller really going to be? To read more about it as the information unfolds, check out the topics in the Steam Universe forum.
If you’re interested in joining the hardware beta, head on over here, but space is very limited.
