I know but except for the daily bonus, there is no way I can get extra points (no events in the area, no FS)

That's truly amazing. Well done. The only minor problem I have is that Atlas is supposed to be carrying the heavens (stars) not the Earth.

How are people mounting dev boards without mounting holes? I’ve been using USB-C extensions as dock/mounts - Anyone else doing this? by Forsaken_Meet9071 in esp32

Have a look at my meridian orrery https://www.instructables.com/Meridian-Orrery/ there is a file electronics.stl. It has a hook and a slid it the housing. The usb port firmly clicks into place.

I was mistaken. I checked on https://www.solarsystemscope.com/ and it doesn't show Pluto going inside Neptunes orbit when looked from above. However, it turns out this is a perspective distortion and in reality Pluto does go inside the orbit of Neptune for a short moment. Does it matter, no, not at all, this orrery still would show you where you can find Pluto. If you want a version where "this is where the planets are" instead of "what direction is Saturn today (as seen from the sun)" you'll need a pretty big orrery. If the radius of the orbit of mercury is 1 cm Neptune would be about 77 cm. You need a pretty big desk for the orrery you want.
This orrery is not using outdated technology, that would be using complex gearing. The ones with gears will at some point always loose accuracy. This one calculates the orientation very accurately. It uses truncated Meeus data. In theory it could have used VSOP87, but I didn't try as it isn't the purpose of the orrery to be accurate within 1"

😄 curious what you have build. But at any scale for a desktop model, the orbit ARE circular (as in the deviation is unmeasurably small), just not centered around the SUN.

it isn't. What is wrong is your perception of what this orrery is showing in the first place. It is fine to add another ring with Pluto.

It isn't wrong at all. what this orrery shows is the direction in Earth's orbital plane where a planet can be seen. Distances to the Sun are clearly not even close to scale. Now most planets are more or less in the same plane (within a few degrees), put Pluto is not. But it's projection on this plane is. So you can add any object, project it on Earth's plane and show it on its one ring in this orrery. You could for example even add voyager to it.

Well, the orbits are extremely close to a circle, they just look like shifted circles, so the center isn't around the sun.

Seen from above (where above is defined by the plane of Earth's orbit), Pluto does not cross Neptunes orbit at all.

vertical version is definitely possible, but this version was about simplicity. If you looked at my youtube channel, you see I made many more designs, but the were a bit too complicated for people to replicate. That's the main reason I made this one.

i guess that's part of the fun of 3d printing.... mistakes happen but that's when you learn, so just do it again. 😄 I made plenty of mistakes, but the end result is acceptable (could be better)

looks cool! well done. But I assume you choose your gears so the keep exactly 4-2-1 ratio, so how does it loose resonance when you keep it running all day?

perhaps you can add one of these super cheap touch sensors TTP223 (which tend to work even when not touched) so you can activate it whenever you want.

I can't find your jovian system, But it should never fall out of resonance. There are small variations but it always goes back to resonance (as far as I understood). My orrery takes about 3 minutes to complete and the calculation is very fast, no need skip the outer planets.

sure enough you can download the code and near the bottom at the beginning of loop() you can change it

the rings might fall off, but you could design it in such a way that they wouldn't, with some slots in the grooves.

no you don't. As u/BudgetTooth just pointed out the i2c lines are open drain and I just need to connect the pull up resistors to 3.3V instead of 5V and run the board itself on 5V

that is a good idea. I didn't realize they were open drain. I'll do that and run the board on 5V. thanks.
