After building my Nipkow tv (32lines 12,5frames) earlier this year. Now finally made a good disk. Electronics are no problem here, but making mechanics with precision are.

To make things easy and maybe help other amateurs, I planning to make a universal pattern generator. Unless they exist apart from the software (pc) solutions(s). I was not able to find a design, so I make one myself. Can anyone give me advice concerning the number of lines and frames. For now I have a design that covers 10-30 frames, 10-100 lines normal or interlaced and with adjustable V sync (negative or missing sync) What do you like to see and is missing? Thanks in advanceā€¦
