Already built a vertical flat sundial with 240 m^m http://kepleruhr.eu -
horizontal ones could be much bigger...

In some practical matter:
Using sundials you can:
- directly observe behaviour of nature, especially the planetarian movements
- get in touch with our solar system
- get some analog feeling of time by observing the shadow movement
- check for different parts of movements due to day time deviations
A very useful and complete SW tool for designers of sundials of nearly all
kind!!
--> Thank you Helmut!
Regards
Kurt
P.S. Little quiz:
1) Anybody knows this sundial here -where am I?
2) Whats wrong with the dial (image taken at 4 pm local time)?

Hi All,
just added two videos about final works:
1) about the indoor sundial:

Hi Steve,
my first thought: I (as XII) as single line to be correct at the noon line.
Getting the geometrical center of XII is not that easy.

The calculation in between should not be a problem by GPS driven
watches/smartphones/IoT-devices. Even mechanic watches would be able to do
the job for EoT - EoL can be set manually if necessary while travelling.

Dear sundialists,
within my sundial-/webcamproject https://kepleruhr.at/en/live-view I
already declared the following relationship:
UTC +
EoT (equation of time) +
EoL (equation of longitude) =
LAT (local apparent time) =
WOZ (Wahre Ortszeit) [German]

Very sad news. As an austrian GSA member had the chance to meet him several

It is still a shame, that DST is really that prominent. I stay in Europe
and hope we can get rid of it - dammned DST.
I am still very emotional about it and see it as one of many homan made
mistakes.

Noon is noon while the sun is up in the sky - over and out.
