This is exactly the type of thing we need to see a whole lot more of.
The website has all the details. It is a very well laid out and developed site allowing us to source all the components and instructions from there or on our own with the information provided.
There is a solid focus on documentation and its all open, so we can use all the work done to build on. This looks like a great project for us.
