Re: Pupil Project
It looked to me like it was universal. Either way, good models are on my web site as wel as Carl's Sundial Primer. And their is a published book on nothing but paper cutouts.

I think I would suggest making an universal ring dial since it would be usable just about anywhere. A link to making one from cardboard is here: http://leewm.freeshell.org/origami/ringdial.pdf Another link to making one using an embroidery hoop is here: http://www.angelfire.com/my/zelime/sundials.html#hoop it also includes a number of other neat designs and links. Have fun with your project! Enjoy the light! Thanks to those that gave me the clues to sign in to gmail and remove some of my security so I could finally see the image you linked.

Re: pupil project
@John: this is a good idea and in fact what I want: they should get curious about sundials and understand the basics such that they will be capable to create their own design and shape of a sundial, eg as you described! @Edley: With Donald's help you could see what I have in mind. @Donald: Thanks for helping and I will try to learn myself as much as possible as well; but it's only half a day though... @Carl: Thank you, your site is really great. I wanted to make something out of wood or so, not paper. But your ring sundial looks so cool, I will propose this one to the kids as well. I will post my experiences and our success here on the mailinglist when we finished the project: thanks for all your ideas and help!

FW: Google Method of Finding Declination
Hi Walter (Hope you don't mind if I cc Sundial List) Ok- I'll try to describe it. Finding Wall Declination using Google Earth 1. Download and install the latest version of Google Earth which has clearer and better images. See: http://earth.google.com/ 2. Open GE and find the location. Zoom in or out to get the clearest view of the wall or roofline. Make sure North (the N on the compass) is straight up. 3. Click on File then Save then Save Image. An Explorer window appears. Give it a name and save it as a .jpg in your files. 4a. If you don't have a CAD program, then print the photo on a piece of paper. 4b. If you do have a CAD program (I use DeltaCAD), then import the photo into it. 5. Draw a line over the photo of the wall or the roof line above the wall that will have the sundial. 6. Draw a north-south line that intersects the wall or roof line. 6a. If using a paper print, measure the angle of declination (degrees East or West of South) of the wall or roof line, using a protractor. 6b. If using CAD, measure the angle of declination by using the angle dimension tool. Done! p.s. There is another Satellite image website that sometimes has better satellite images than Google Earth. It's called Bing Maps (formerly call Virtual Earth). See: http://www.bing.com/maps/?FORM=ZZLH8# Use it the same way as Google Earth. -Original Message- From: Walter Sanford [mailto:wsanf...@wsanford.com] Sent: Wednesday, June 24, 2009 2:35 PM To: John Carmichael Subject: Google Method Can you explain the Google method for finding declination?

Re: Google Method of Finding Declination
FW: Google Method of Finding DeclinationHi John, Thanks for publishing this technique. I would recommend your technique when it is important to get it right. If a customer wants a precisely crafted sundial, your technique is almost as good as being there and using Tony's wonderful declinometer. For more casual uses, I would recommend Damia Soler's web link. http://sundial.damia.net/ This now works like a charm. Click on two points on a Google Map to produce a line with text indicating the location with lat and long noted as well as the correctly calculated the wall declination. The result is now within a degree of what I had found with Google Earth methods. Google Maps is pretty good for resolution, although Goggle Earth gives 3 D effects. Results vary but around here the Google camera car has been taking ground level pictures so we can expect pretty good resolution in the future. I recently gave the Google camera car an appropriate salute as it passed. I have found Yahoo Maps to give somewhat better resolution but the web link is based on Google Maps. If the building is too small to give you a clear line, use the adjacent road as your baseline. Damia's web link also gives you the standard hour lines. If nothing else this is a good check for the professional design.

RE: Google Method of Finding Declination
Hi Roger and all: This is the first time I've seen Damia Soler's Sundial Location Calculator webpage at http://sundial.damia.net/vertical/sundial.php?langcode=en/ .It's fantastic! I'll put this website at the top of my bookmarks. I nominate it as The Dialist's Tool of the Year! It combines the features of Google Earth with the features of a CAD program! How cool is that! And it gives you the latitude and longitude too. It's so easy to use a child could use it. It's just as accurate as my method I would guess, but even easier. You can use just part of it to get a wall's declination, or you can use all of its features to get a design for his sundial. Congratulations to Damia Soler for coming up with this great dialing tool. I love it!
