Great idea, the digital sundial, – I remember that I have read in an old “Scientific America” (about < 30 years ago) that somebody should construct a digital sundial.
Now You have done, – and I want to do it soon, – I am only perplexed by the number of gnomons in Your files, – there should be only one for every hemisphere or have I misunderstood something completly ?
Thanks for sharing,
