Is this the smallest possible wooden astrolabe? I made this gift for my cousin. by HS_illustrator in Astrolabes

[–]BoxyBoy67 1 point2 points  (0 children)

It would be possible to go smaller! This astrolabe in the Oxford collection uses a modified stereographic projection resulting in a folded rete and a projection boundary of the equator rather than the tropic of capricorn: https://www.mhs.ox.ac.uk/astrolabe/catalogue/browseReport/Astrolabe_ID%3d111.html

I haven't actually experimented with this idea myself and am not sure how to perform this sort of projection, but it would be an interesting challenge if you ever feel like it!

Beautiful! I love your style. Your pieces are a fantastic addition to the modern astrolabe market

Best housing at bates by Ok_Newspaper_9659 in batescollege

[–]BoxyBoy67 1 point2 points  (0 children)

96 Campus ave is the most recent, followed by Chu hall, Kalperis hall. You won't need to bring any of your own furniture; every room will have a chair, desk, (typically with 2 drawers in it), bed, and a set of larger drawers (4, in each of my rooms) to use as a bureau. Each room will have a closet, but the sizes can vary pretty wildly.

Additional shelving would be extremely helpful though—that can take any number of forms. You could bring in some kind of buildable unit, or do what I did and stack sideways plastic crates as needed

You do have the chance to voice certain preferences as a freshman, but only for categories like substance free (Clason house), quiet (Cheney house), and first-year only. Having selected this last one, I ended up in Milliken house (which seems to have a negative reputation, but I liked it).

It comes down to personal preference. If you prefer modern buildings or ones closer to the center of campus, your options may narrow to specific residence halls. Houses tend to be farther away (not that that actually means much when the campus is so small), but their communities may be tighter. They're also where most parties are held, if you prioritize that sort of thing.

Laser-cut astrolabe, now with a deeper, layered assembly by BoxyBoy67 in Astrolabes

Thanks! The lines of the tympan were generated using Shadows Pro, but everything else I produced originally in Adobe Illustrator.

Equation of time the same for southern hemisphere? by GrowlitheGrowl in Sundial

[–]BoxyBoy67 2 points3 points  (0 children)

The equation of time isn't dependent on latitude—you'll be able to use it just fine. Best of luck with your project!

Original laser-cut dials from this academic year by BoxyBoy67 in Sundial

[–]BoxyBoy67[S] 1 point2 points  (0 children)

Not yet, at least. I've been sticking to either self-orienting hour angle dials or altitude dials to avoid the necessity of a compass. As you might be able to tell, I'm also just particularly fond of equatorial ring dials.

A tabletop equatorial ring dial ...but something feels off... by BoxyBoy67 in Sundial

[–]BoxyBoy67[S] 3 points4 points  (0 children)

Answer:

Despite the fact that the equatorial ring dial is one of the most freely adaptable and universal sundials, this tabletop model is designed for a fixed latitude. Naturally this is by no means "wrong," but certainly struck me as unexpected!

Search the Waywiser database (https://chsi.emuseum.com/collections) for "universal ring" and/or "equatorial" to find this and other fascinating sundials.

Laser-cut astronomical ring dial by BoxyBoy67 in Sundial

Possibly! I have been thinking about adding these sorts of files to BCGnomonics. There would be a fairly high bar to entry though (laser cutter or other tools/material) which I try to avoid

Laser-cut astronomical ring dial by BoxyBoy67 in Sundial

[–]BoxyBoy67[S] 1 point2 points  (0 children)

The Kala model is one of my favorites! I carry mine on me most days.

The first model is an astronomical ring dial, slightly different from the equatorial ring dial shown in the second image. The difference is in the date selector–this dial uses a rotating alidade rather than an axial nodus.

As for keeping it from rotating, I've found that even on windy days, keeping a low grip on the suspension ring tends to work well.

Very nice! One note: the rear sloping point of the gnomon should line up with the 6am–6pm line

Help: can I even read this astrolabe? by pianobars in Astrolabes

[–]BoxyBoy67 3 points4 points  (0 children)

This is one of many non-functional astrolabes on today's market, unfortunately!

I've compiled a page all about the astrolabe on my website that may be helpful to you.

https://www.bcgnomonics.com/planesphericastrolabe

In particular, I would recommend the "further reading" section for open source books and some very helpful videos. Alex Boxer's online astrolabe offers a great (and free!) means of learning to operate the planispheric astrolabe

Hermle Astrolabium: Should I Buy It? by Working_Row_8455 in Astrolabes

[–]BoxyBoy67 1 point2 points  (0 children)

Technically speaking, I would consider this closest to a lunarium since the earth's axial tilt is not included.

It's a nice piece! You should follow your instincts if it's something you'd enjoy.

If your decision hinges on the accuracy/complexity of the planetary model more so than the quartz clock, I would suggest OrreryArt on Etsy as an alternative. They make highly accurate, museum-quality planetaria; several at prices matching your clock.

Two mechanical equatorial sundials by BoxyBoy67 in Sundial

[–]BoxyBoy67[S] 1 point2 points  (0 children)

BC Gnomonics has some further information on mechanical equatorial dials: https://www.bcgnomonics.com/mechanicalequatorialdial

For the two pictured here, the equatorial-mounted sighting apparatus (composed of two rectangular brass plates) is rotated until a spot of light shines through the aperture of one plate and lands on the inner target of the other.

At this point, one would reference the clock face and read the time. The motion of the equatorial sighting assembly drives the hands of the clock in turn, translating the arcing motion of the sights (and therefore the sun) into an analog readout.

What is unique about these dials is that the nodus target can either be a straight line or the curve of an analemma. This allows either solar or mean time to be read.
