And the icing on the cake is... the way that worked in the end only took me 3 or so days. And that's with thinking time! So here's hoping the Ellie Rig'll take no more than 2 days.
So annoying that I've been hitting a wall with this for about 3 weeks, and suddenly it clicked. I mean, it's good that it clicked, but it took so long. Don't get me wrong, I do enjoy the learning process, but I don't really have time for it at this point!
I won't bore you with technicalities at this point, I'll just stick up a few pictures.
I'll try to put up a video over the weekend of the rig working!
