The Astrolabe as an Artist’s Tool

In this week’s email: “I use your astrolabe constantly for my artwork, I make extremely long exposure pinhole photographs tracing the suns path over the course of a day to half a year.  I use your astrolabe to determine rise / set times and declination as well as the transit alt for the sun. Then plan which time […]

Major Update!

Yeah, I’m still plugging away, between burnout and other commitments I haven’t had a lot of time for this project. This has changed with the turning of the year. First up, I have made a major update to the Astrolabe Generator. I finally figured out a way to digitize a set of zodiac symbols and […]


I hate script-kiddies and their ilk. A few days ago the site was hit with a PHP injection attack that had its pages redirecting visitors to malware infested sites.  I was on the site less that two days before I discovered this problem, so hopefully not too many people where afflicted.

Current Progress

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 […]

Random Jottings

The Missing Manual has gone missing! As some of you might have noticed, the Joomla site for Astrolabe: The Missing Manual is gone. Like the original wiki it replaced, it was not meeting my needs, so I nuked it.  Do not despair! The manual still exists, and is still being added to regularly (more regularly […]

For those of us that like to put the science into Arts and Sciences, Artisan’s Row at Pennsic this year will have a day devoted to scientific instruments and tools. I have been asked by the Artisan’s Row Dean to organize a day devoted to the tools and instruments of the sciences. I am looking for like-minded artists and […]

The Future: Version 3 of the Astrolabe Generator

I spent most of the last weekend coding like crazy. I now have three new optional scales to add to the back of the astrolabe: The Lunar Mansions. A calendar/astrology scale. This is visible inside the shadow squares, center bottom. Two views of the Arcs of the signs: Equal sized and projected(top left shows the […]
