Introducing the Advanced Astrolabe

For quite some time now I have been basing my class, and my discussions here, on an astrolabe with fairly basic options. Linked to the right you will find a zip file containing the components for this basic astrolabe, along with the handout for my class. But there is more to the astrolabe than just […]

Another astrolabe in work

This one is a metal astrolabe. A work in progress that uses some of the output of the Astrolabe Generator. Images used with permission.

An Astrolabe in Work

What I’ve been up to

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 […]

This took a bit of recoding and rearranging some of the functions, but the result is now up and […]

There’s an App for That: An astrolabe 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, […]

Bug Swatting and New Options

One of the Astrolabe Generator’s users, J├╝rgen 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 […]

Swatting Bugs

I spent the last few hours noodling around with the generator code. I fixed several bugs. I also removed, at least temporarily the 6 and 12 degree twilight lines as they were cluttering up the plate and serve no real purpose.
