TechnicBrickPower Posted March 13, 2020 Posted March 13, 2020 Today is PI DAY! A very important day for all mathematicians to celebrate. What better way to celebrate than combining it with Lego Technic?! Here I present a PI Day special Lego Technic MOC that produces a gearing ratio of PI to 6 decimal places. This is using two differentials to produce a gearing ratio of 355 to 113. Happy PI Day. Quote
TeamThrifty Posted March 14, 2020 Posted March 14, 2020 Brilliant.. loved your previous too. Love the logic and the smarts being used. I'm a little bit in awe.. Quote

LOL Do you have ideas I can work on? Quote
Aleh Posted March 16, 2020 Posted March 16, 2020 Wow! I can't imagine even how did you calculate so accurate input. Really a brilliant machine! Quote
aeh5040 Posted March 16, 2020 Posted March 16, 2020 This is brilliant! And almost certainly completely useless (this is also a compliment, coming from me! ). You asked TeamThrifty about other ideas. Have you seen Oskar van Deventer's billion-to-one gearing? There are some similar calculations involved (see the 2nd video). How about emulating that in Lego somehow? Quote

LOL My videos are more about sharing techniques for designing certain gearing ratios. You'd be surprised where that could come in handy. That billion to one gearing system is really interesting. Did the guy 3d print those? Yes thank you will add that idea to my list. Quote

He is perhaps the world's leading puzzle designer, but he has lots of interesting gearing ideas too. Quote
