Moon Phase Clock V2

thingiverse

I've made all the corrections... it's working now ;) It's a simple moon phase clock. You'll need: A simple quartz clock All the 3D printed parts Maybe some glue to maintain all Moon Phase Clock Overview and Background In this project, you can learn some basic introduction to programming and gears. It's recommended to have some knowledge of modeling and having a tool that can create your gears (it's not that easy!) Audience This project is for students in mechanical and other studies who require knowledge in gears and power transmission. Subjects 3D Modeling Gears Power Transmission Simple Programming Activity The principle of this clock is very simple. We use a low-end quartz clock as the "motor" to operate the mechanism. We have a motor that turns twice a day (the time part) For the moon, a rotation cycle lasts approximately 29.53 days (more precisely => https://en.wikipedia.org/wiki/Phase_lunaire#Positions_par_rapport_au_Soleil) We have a reduction ratio to aim for of about 29.53:1 (which I've repeated at 118 to fix the problem) We know that the reduction ratio R = product of leading teeth / product of driven teeth There is a constraint in creating gears with an FMD 3D printer, we cannot make gears with a module smaller than 1 mm. I don't want to pay for a calculator to calculate the gears that will work well, so I made a little program that finds them for me (which I've put below) I chose to use the combination A=12 B=68 C=30 D=37 E=23 F=49 G=15 H=119 Which gives me a reduction ratio R = (BDFH)/(ACEG) = 118 Preparation For the material, you only need one simple quartz clock (... and a 3D printer!) https://en.wikipedia.org/wiki/Transmission_(mechanics) Rubric & Assessment The goal of this project is to make a moon phase clock with a simple clock. I made a simple one and tried to make it cool, but you can use any other kind of gears... there are several other ways to do (as long as the ratio is respected) Code for Gear Program Before anything else, as an IT professional, I'm completely aware that this code is very ugly. There's no research to reduce calculation time by removing already tested occurrences ... it takes a monster time to do all the calculations, but for such a small project, it works very well!) #include using namespace std; int main() { //Variables for 8 gears double A,B,C,D,E,F,G,H; //Variables for extremes and margin double maxi,mini,Mmaxi,marge; maxi=70; mini=10; Mmaxi=30; marge=0.000001; //Variables for result double resultat,interResult; resultat=118.122351924; cout
