Building Instructions for Rubik's Cube solver

A month ago Brian Davis posted about Hans Andersson’s Rubik's Cube solver. Yesterday when I visited his website I realized that Hans had published building instructions. All though you need some replacement stickers for your Rubik’s Cube the machine can be built form a single Lego Mindstorms NXT Retail-kit. To download the building instructions and the NXC program go here.
Comments
I added the Rubik's Cube solver as the first submission to this board. Maybe we can get some comments from people an how easy it is to follow the LDD BI's.
It would be constructive for individuals to offer recommendations on how to use LDD rather than simply trash the product.

Maybe the creator used a lower mAh rating, but fully charged 2650mAh batteries need to be ran down a bit.
Good work Hans, and that from 1 NXT kit !
Are you visiting LEGOWORLD Norway?
I would love to see your model in action.
