It's been a while since I've been on here but there has been some interest in the quad gauge I built and posted a few years ago. Post I've decided to release all the technical design information as open source so that anyone can build one. I'll be happy to fill in any missing blanks or answer any questions. Unfortunately, real life is putting a real limit on my time so other than information, I can't provide much else. Everything you need should be available on this repository.

Amazing work. Very grascious of you to post up that work for others to use.

Thanks Evan!

@Evan0 - great work and nicely documented!

What a great idea - I am sure there is a market for that.

Well done, Sir!
