Saw your post on reddit. Again, this is awesome. The actuation looks very smooth. This post answered the question I had over there - I was wondering whether the bolt was driven directly or by a piston. What's the threading on that fill valve? This could open up a lot of opportunities for me.

Your run-of-the-mill barometric pressure sensor won't do it.

This is an extremely clever design. Awesome work

Again, 10 years ago I would have agreed with you. A lot of my vitriol comes from the disappointment comparing the romantic notions I was raised with to reality.
