Build A Sundial

Build A Sundial

       Here's a just over 11 minute you tube link on making  a horizontal sundial:  http://www.youtube.com/watch?v=14GOFiJSElI   It does get a bit geeky.

            Here's a shorter  (like 9 minute) you tube link on more primitive solar training about direction using the sun:   http://www.youtube.com/watch?v=u3l49zQREcY   It is OK

            Now as to the time of the day where you live, here is one more you tube link:  http://www.youtube.com/watch?v=u3l49zQREcY  This link is like 6 minutes long.

            Last, here is a simple written link with pictures on how to make a sundial to tell time, etc.: http://www.wikihow.com/Make-a-Sundial

Of course the sun does have to shine; in other words not any day or season will do.

Even the error may vary by minutes, but so what, like compared to nothing.

If I have to go on security patrol at 0400 in the winter, then having trust in the time is a big deal.
