This one is a metal astrolabe. A work in progress that uses some of the output of the Astrolabe Generator. Images used with permission.
I got this last night via Twitter: https://twitter.com/cforchino/status/434176137216794626 Nice work, he has a steadier hand than I do. Please do email or tweet me your astrolabes, I’ll be glad to post them. Addresses are on the right.
(Ok, so I’m a bit late with my essay “What I did on My Summer Vacation”, sue me.) I committed to three activities related to this project this past Pennsic: Firstly, I taught a pair of two-hour sessions of my class “The Astrolabe in Theory and Practice” at Pennsic University. In addition I displayed my […]
Wow, how time flies. It is almost a year since I last posted here. New Years Resolution: Post at least once a week. Yeah, let’s see how long That One lasts… Not that I’ve been idle. In the intervening months I have gotten quite a bit done, I just haven’t been sharing. Since my last […]
Even though I haven’t been posting, I have been busy. In addition to the changes to the Astrolabe Generator mentioned in the previous post, I was asked to teach a class at a small gathering of medieval reenactors last month, and so had to to get my class handout updated ahead of schedule, and a […]
I’ve been lax on updating the blog lately. Not because I’ve not been interested, but because I’ve been busy. First off: I have received two requests to modify the Astrolabe Generator to support the southern hemisphere. This took a bit of recoding and rearranging some of the functions, but the result is now up and […]
The first step in drafting the astrolabe climate plate is to lay out the Tropics and the Equator, along with the meridian. As these markings will be the same for all the plates, it makes sense to draw each line on all the plates before moving on to the next line. This way, I can […]
The unequal hours arcs have now been added to the back of the astrolabe. With the exception of what little decoration I’m planning, this completes work on the back of the project. With the front and the back now finished, the next step is designing a set of climate plates. Doing five of those will […]
As I mentioned a while back, there is a developer out there using the output of the Astrolabe Generator to create an astrolabe app for the iPad. Well, version 1 is complete and available for free on the App Store. The website is: http://taucetisystems.com/. I have not had a chance to look at it yet, […]
One of the Astrolabe Generator’s users, Jürgen Hoefeld, spotted a problem with the alignment of the Houses of Heaven, the intersection point should be on the horizon, and was not. I have it fixed now and the changes checked in to SourceForge. I have posted the updated generator to the site as well. In addition […]
