Dear All, As some of you already may have noticed, I have recently worked with my electrical sun dial project. Instead of a shadow the sun's position is in it calculated from the output of two or more solar panels. I have now tested the first prototype and found it capable for surprisingly accurate results, +-40 sec or even better, if the conditions are good. A description of the project is available at http://pc-calculator.110mb.com/sun/digital-sundial.html It has been really amazing to see how tiny movements of the sun the instrument capable to observe.
