The Astrolabe Generator 3.0

After much hard procrastination, I am happy to announce the release of version 3.0 of the Astrolabe Generator. The old Flash version was difficult to keep improving, and is no longer working in any case. The new, downloadable version has several bugs removed, and much expanded capabilities: Save to folder or zip file Print to […]

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 […]

Current Progress

Even though I haven’t been posting, I have been busy.

Drafting the Astrolabe 12: The climates part 1

With the front and the back now finished, the next step is designing a set of climate plates. Doing five of those will […]

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, […]

Drafting the Astrolabe 11: The Unequal Hour Arcs

The next step, and the last scale to be added to the back of my astrolabe, is the unequal hour scale. In the middle ages, there where several timekeeping systems in use, as opposed to the single one we use now. This next scale was designed to convert between two of these systems: The Equal […]

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 […]

I thought I posted this two weeks ago… Work and life have gotten busier than I realized it seems. Anyway, here is the completed shadow square section. Next up will be the unequal hours scale and then the back will be done.
