gnomoni.ca - by Steve Lelievre
This website is going to be the new home for Steve Lelievre's repository of sundial-related documents and programs.
You've caught me at a bad time - I've closed down my va7lel.ca site, which was mostly related to amateur radio, but have not started on construction of a dedicated sundial site yet. Thus gnomoni.ca is only a placeholder at present. I have only a few links in place:
My Sundial Generator programs
- Layout for a Foster-Lambert sundial that shows the time remaining before sunset - draws parts intended to be cut from a sheet of ply: Visit
- Layout for a Solar Decliner vertical sundial that shows the time remaining before sunset - draws a dial face intended to be printed on vellum inserted in the front of a deep frame with a mirror at the back: Visit
gmath: my gnomonic add-on for Excel
- Documentation (PDF)
- Excel add-on file Note: Do not open this file directly from your browser - you must download the file and then install it according to the instructions in the documentation. As well, if you're a Windows user, depending on your version you will likely need to alter the properties of the downloaded file: before installing the add-in, right click on the downloaded file and choose 'properties'. If you see a note about the file being blocked, you'll need to unblock it. It's a Windows security thing (put the file through your anti-virus software if you feel the need to check it before unblocking). If you do not unblock the file, then Excel will install the add-in but every time you restart it after that it will report being unable to find the gmath functions.
