Mechanical TV Project
Posted: Thu Jul 12, 2018 2:21 pm
Good evening,
I am working on a home project to build a Mechanical TV. Currently I am trying to work out the Nipkow disk. I am using a 12" (304.8mm) vinyl record as the disk itself and trying to work out the hole sizes to use. I read somewhere to use a 1/16" (1.57mm) drill bit. I was pretty pleased with that notion because I felt I would probably have no issues drilling through records at that size. In solidworks I drew the disk and placed these holes and was not pleased. The pattern did not look like it would be correct for a Baird style tv. The hole patterns would cover too much are. Thinking there would be less light let through away from the center I allowed the holes to overlap (1.2mm center to center) but still it looked much more wide than tall.
So guess I am looking for someone to maybe give me advice. Should the holes be overlapping more or am I just going to get a much smaller bit. I am going for 32 holes.
Thanks for any suggestions you can offer.
