Here is my new watch face with some modifications suggested by @russellcresser.
I had no difficulty figuring out how to set the x&y coordinates for the toothed gear rotating around the perimeter of the tourbillon using the formulae in the Facer documentation, but I can’t figure out how the radius is set, although it appears to be just right. I’d love it if I could slow down the rotation around the center of the tourbillon. I look forward to @russellcresser posting info about rotations.
Thanks @russellcresser and @rob.fisk. That’s a lot to look at and I’m not too sure I understand it. Even though I took physics, calculus, & differential equations in college, after 40 years as a pediatrician, I don’t remember much math. But I will keep staring at it and try to grasp it. In the meanwhile, I’m reasonably satisfied with what I have done, although I wish I could slow down the orbital rotation.
Thanks. Although I’m excited to try to understand all the phenomenal advice I get on this forum, this simple fix is what I need right now.
Can I ask, since you seem to understand the formula, how is the radius (the distance from the the center of the orbit) determined in the formula I used? It just seems like luck that it worked for me.
You guys rock, this thread is a great education I hope to be able to read properly later (in bed on my phone right now, should get some sleep ). All these toribulumious thingamebobs look great, and I particularly love how yours is moving @richiebee Great work all of “yous guys”
I did notice a couple of ways of doing the rotation when I started on mine but ended up with the cos(rad version. So for one of the 2 outer cogs I have
X Pos: (160+(45.5*cos(rad(((round(#DWFSS#)))-303))))
Y Pos: (85+(45.5*sin(rad(((round(#DWFSS#)))-303))))
The first number is the rotation center, the second one is the radius.
I used round() on the DWFSS to get a 10th second tick step.
The final number is the starting offset degrees.
Sorry I had to got to bed. Time Zone Problem. @wsilbers as you say it is a good strong topic.
Basically all these formulas are the same but with different structures and tweeks. I find it very difficult and it seems a lot of us by have come to this advanced maths stuff about 40 or 50 years too late.
I think the Tourbillon is looking great. Good logic and good speeds. I think it is great that you have someting going on down there that is not a model of a real one, but certainly has the Spirit of the Thing.
Well done to everyone else showing the True Spirit of this Forum.
