In the interests of full disclosure, this was submitted earlier here:

However, that submission was incorrectly marked as a duplicate of this submission:

https://news.ycombinator.com/item?id=12101908 (video)

But it's not a duplicate - they have different information. This submission is the web site of the project and has links to files and "how to" documentation. The second submission is to an hour-long about the project, and while it contains information, it's fundamentally different.

I don't know why the original submission of this link got marked as a duplicate - I believe it to have been a mistake.
