Here at "Sunny Day U" we want everyone to be able to enjoy making a sundial that will actually work. So we have put together a number of paper sundial kits. Some are quite easy to assemble but there are a couple that are a challenge. All are possible as can be seen from the models below.
The kits are available in models for both the Northern and Southern Hemispheres. Some even come in various sizes. All you need are scissors, glue and a little patience. Try them all!
Each of these sundials is illustrated with a 3-dimensional drawing that was created using a CAD (Computer Aided Design) software package. Once the sundial was drawn a light source was defined. This light source simulated the sun. To do this a latitude and longitude were entered to position the sundial anywhere in the world. A month, day and time were selected. The sundial must be positioned correctly in order for the sun to illuminate it as it would if it were real. The 3-dimensional drawing is then rendered. This process gives the drawing a photo-like finish. It also projects a shadow on the sundial that appears as it would if you were looking at a real sundial. In every case the time shown on the sundial images matched the time that was entered.
This technique could be used to check a sundial design. Creating the 3-dimensional drawing can take quite some time if it is complex. The Sundial Primer has many interesting 3-dimensional sundial drawings used to illustrate the various kinds of sundials presented there.
All of these sundials indicate local apparent or solar time. To convert this to clock time you need a "Correct-A-Dial" or "Correct-A-Dial II".
For both the Northern and Southern Hemispheres!
Paper sundial kits for 21 types of sundials available in 74 models.
Equatorial Sundial Kit
This sundial won't take you long to put together. This is a great science project.
Polar Sundial Kit
This sundial is even an easier one to make. You don't have to find a gnomon.
Cycloid Polar Sundial Kit
The cycloid polar sundial is very unique. You will discover its special qualities when you make it.
Cross Sundial Kit
This sundial will take a bit of patience to put together, particularly if you decide to make the small one.
Equatorial Ring Sundial Kit
This sundial is a variation of the equatorial sundial shown above. It's a little tricky to put together. Be careful to align the parts.
Star Sundial Kit
This sundial is as much fun to make as the cross sundial.
Horizontal/Analemmatic Sundials Kit
This is a very useful combination of sundials. They will help you to find your local meridian.
CD Sundial Kit
This sundial is easy to make and a lot of fun to use.
Gnomon-less Equatorial Sundial Kit
This sundial has no gnomon! Hmmm...How do you tell what time it is? That's easy!
Universal Analemmatic Sundial Kit
This sundial is easy to make. The challenge is the frame it is mounted on.
Digital Equatorial Sundial Kit
If you are looking for a challenge try making one of these sundials. It's really not that hard!
Standard Time Equatorial Sundial Kit
This sundial will actually tell you clock time! What is a vernier scale? Come and find out.
Globe Sundial Kit
The only paper globe sundial kit in the world!
Universal Ring Sundial Kit
This sundial will work anywhere! It's fun to make too.
Pinwheel Equatorial Sundial Kit
A slight variation in the layout of the hour lines of an equatorial sundial makes for another interesting sundial. Give it a try!
Universal Horizontal Sundial Kit
Here are a few cool looking sundials that are easy to build and will get a lot of attention!
Universal Foster-Lambert Sundial Kit
This sundial is similar to the Universal Analemmatic Sundial but instead of ellipses it uses circles
Universal Bifilar Sundial Kit
This is quite a different and unique sundial that uses a couple of pieces of string to tell the time.
Standard Time Equatorial Ring Sundial Kit
A little twist of the Standard Time Equatorial Sundial shown above will give you this sundial. A bit of a challenge!
Universal Hours Before Sunset Sundial Kit
If you want to know how long before the sun is going to set than you need to make one of these sundials.
Modeling Tips and Techniques
While making these paper sundial models I learned a few things that just may help you when you make yours. Remember that these are only my suggestions. You may find some other ways that make building these sundials easier. In any case I hope that you have fun making and using these sundial models and perhaps learn a little about sundials along the way.
