MOC Pi Day Gearing Instructions

[TechnicBrickPower]

Hi All, I have made some build instructions for my Pi day MOC gearing mechanism that I made a while back. It implements a gearing ratio of 1 to 3.1415926 using two differentials.

Here's the video about it:

and the instructions on rebrickable:

Wow! That is impressive and complicated! I would have had no idea where to start on a project like that, but I think you did a good job!

I assume you mean 3.1415929...?

Of course, you made good use of the fact that pi is so very close to this particular fraction (355/113). So, the next challenge would be to approximate the golden ratio to the same precision, because that number is specifically known to withstand easy approximation by fractions.

For the rest, as always, good job, and as far as I know you're the only person that uses Lego and TeX together in projects. :D

Hi Erik,

Thanks - yeah I did mean that ;). The Golden ratio - yes that would be a good challenge! Appreciate your positive feedback - and yes used to use LaTex in my uni days - old habits are hard to break. You're the first person to notice lol.
