Asking cause that mod seems to have gone off the face of the interwebs and none of the folks who work with Rob (or Rob himself) reply to me.
I don't have it either. I was a teenager when I made that guide, and didn't even know which end of the soldering iron was hot. You shouldn't have any trouble reproducing it without the guide.
I might remake it, but it's fairly low priority in the midst of everything else I need to sort out first.
I was able to dig up some of our old emails detailing the mod and got them to Max.
