This is a really cool project, I have been meaning to build one of Annin's arms for a while. They appear to be well engineered and easy to work on, and I really appreciate the fact that many components are available in either a printed version or an aluminum version for when you want to be slightly more professional. I do wish he'd put the code and designs on Github but that's honestly such a minor complaint.
