I have discovered that the files for the five indiators for sunrise, sunset and moon are missing from the the file archive, Is it possible to get them? I enjoyed printing this project--getting the stepper and electronics put togethter now. Thank you very much.

While working in the software, which btw still isn't finished, I noticed that some arms were still brushing against eachother, moving one where it shouldn't. I had 1mm tolerance, but I'm now finalizing a design with 2mm tolerances. I have a remark in the instructable about this. If everything goes well, it should have an updated link to download, you don't have to redo everything only the ones with a capital N at the end. Actually you don't have to redo anything if yours works fine with the 1mm tolerances. The file includes the missing icons.

Antikythira Mechanism

[@illusionmanager]

well not quite, that one is geocentric and has 35 gears! In principle there is nothing wrong with a geocentric view, if you want to know in which direction you can actually see the planets, but for this model I used a heliocentric approach and only 1 set of gears to transfer power from the motor to the mechanism.

@@illusionmanager very nice implementation indeed
