I just heard that the Spare Time Gizmos SBC6120 partial kit is being offered as a Kickstarter project:
There are just 12-days left until the project expires. It currently has 11 of 30 slots filled.
Only 30-slots are available and all must be filled for the project to be funded. No more will be available due to limited availability of the HD6120 chip.
I have signed up for one, so I'm hoping that it goes forward!
