Planetarium Model

[John Wagenseil]

OK, I stumbled across this one again.


This is a very difficult, very complex paper model of a planetarium projector, that when completed will display four axis of rotation.

Building this model will require the same level of skill and obsessiveness to successfully complete as a UHU2 model. Like a UHU2 model I think more people download it and admire the graphics, than will actually assemble it.

This page leads to the link to the paper model:

GSS-CHRONOS/ƒy�[ƒp�[ƒNƒ‰ƒtƒg�bŠ”Ž®‰ïŽÐŒÜ“¡ŒõŠwŒ¤‹†�Š

Find the link to the page with the links to the model about half way down this page, next to the click button that says "top".

The old pre-computer Planetarium projectors were some of the largest, most complex and costly devices ever made, that were designed only for the purpose of "edu-tainment".

It's a great kit. I got a couple of copies form the Goto U.S. rep. at a planetarium conference when I presented about using paper models in the classroom/planetarium. I have 2 printed copies. Haven't touched them yet. I'm not good enough.

This is awesome! Thank you for the link. I have spent literally most of my life working in a planetarium and have seen a variety of projectors. I'd love to build a model of our first projector, a Spitz. Our robot projector was later replaced with the first of the DigiStar series of projection systems, very versatile, though not as impressive to look at (just a box with a lens and a computer in the back room.) A lot of debate has been had over the pros and cons of robot projectors vs computer driven systems. After experiencing both types personally, I enjoy the versatility of computer projection, but I'll always have a warm spot in my heart for "Jake", our old Spitz projector.

I am definitely going to tackle this model, and some day attempt to build a model of a Spitz Projector, too.

PS the pix came from the Abrams Planetarium web site in East Lansing, MI. The Hansen Planetarium in Salt Lake City, UT had the same type of projector.

But does it work? Can you put a lamp in it, and actually make it project?

I would really love to build this one! Thanks for the great links!!

That would be something to see!

I know with, the Spitz projector, the two hemispheres were covered with thousands of tiny pin-holes in addition to the lenses and filters that created the deep sky objects

Great model!!
Thanks for sharing.



Alternatively, you can get the download from the English Language version of the site:

with full English instructions.




Edit:
This is the website of the designer of the planetarium:
http://www.paper-craft.net/
I think I recognize some of his models as those in the Canon website.
There are photos of other great models too.

Thanks! That will make things a bit easier.

The designer is amazing. The Goto rep I spoke to said that Mr. Goto himself approached the designer about making a model of the Chronos projector. He asked the designer if he needed to see one, and he said no. All he wanted was some photos of each side, and measurements. The final model is spot on perfect, and he never actually saw one in person. Just amazing.

Thanks, that looks great. Will put it in the stack but as commented it probably will be unbuild at least for years.
