Hi Anubis; The operation is very related to the "Digital Sundials" <http://redrok.com/neat.htm#sundials>. I have one of the "Digital Sundials International" <http://www.digitalsundial.com/> dials. It works very well. Of course it reads in local "Solar" time.
I think the SD-11 works in a similar way.The sundial has a front surface with vertical line and a similar shadow mask with lines and missing lines that form the numbers. The sundial is unaffected by the vertical position of the sun, only to the east/west motion. East lamp in the SD-11 has a 2 dimension mask of primary holes. One hole for each pixel in the screen. Then a shadow mask with a hole positioned for each lamp to form the characters. I wrote a program. years ago, to make the sundial in large size. Something I could actually make. I suspect making a large display similar to the SD-11 would be much easier to do. Possibly done with a PC board lithographic camera controlled with Gerber codes. I can even see a CNC machine drilling holes in metal sheets. redrok -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
