Drafting the Astrolabe 6: The Zodiac Scale

OK, yes, that was tedious. But now it is done. I have started work on the back of the astrolabe: The first scale, the zodiac ring, is finished. Drawing this used a combination of geometric construction and fudging with the compass. First, draw the outside edge of the astrolabe (set the compass using the finished […]

Drafting the Astrolabe 5: A Recipe for Fudge(ing)

The next big chore will be creating the major scales for the back of the astrolabe. This will involve drawing one set of rings representing the Zodiac and another set representing the Calendar. Drafting the zodiac is straight-forward, if tedious. The circle needs to divided into 360  one-degree ticks. The process is the same one […]

Drafting the Astrolabe 4: The Front

Back to work on this project: I got several tasks done today. When I am finished drafting my astrolabe, I plan on photocopying it onto card stock, and assembling and laminating it in order to compare it’s accuracy to a computer-generated version. I tested the photocopy process today. First, I printed out the front of […]

Astrolabe Generator: Done For Now

I have just uploaded the last tweak I’m planning on making to version 2 of the Astrolabe Generator. I’ve done a lot of work on it over the last few weeks, and I’m happy with the results. I will still be planning to add more scales and functionality in the future, but it is time […]

Astrolabe Generator Update

I have added new more features to the Astrolabe Generator (http://astrolabeproject.com/build/). There is now a front degree scale option and I have added a new set of limb markings: Alphabetical (based on a 1370 astrolabe shown here).

Houses of Heaven

I have added two new scales: The Houses of Heaven are now an option for the front. I have also added a horizontal shadow scale option on the back. The Houses are the first astrology-only scale I’ve added. Look for more in the future. The new shadow scale differs from the shadow squares in that […]

Another update

I’m definitely in a coding mood. I just uploaded another change. I’ve added a Quadratum Nauticum to the Astrolabe Generator “mater-only” option:

Astrolabe Generator Updates

Made some more changes. I added options to print 1 and 2 degree intervals for the almucantars. Also, there is now an option to print just the Mater or just the Plate (useful in creating astrolabes in other materials than paper).

Astrolabe Generator 2.0 Released

I’ve been busy. The final polish was put on version 2.0 of the Astrolabe Generator today. It is up and running (see link to the left). I increased the size of the application screen, re-sized the thumbnails and  rearranged the controls a bit. The thumbnails now update to display the current selected options. I redesigned […]

Drafting the Astrolabe: 3. The Protractor

After Stoeffler This does seem a bit extreme, but the purpose of this project is to see what can be done with just a straightedge and compass. Building my own protractor serves two purposes. One: It proves to me that an accurate tool can be made this way. Two: It gives me a chance to […]
