Vernier clock

Stationary disk with 60 slots, with a rotating disk with delta 1 lines behind.

On a caliper, the vernier site of the scale has 11 increments for 10 on the main side.

Does it matter which side becomes the hand and which the background? Test...

to do

• better prototyping. maybe extension
  • no easy documentation on cloning in scripting

• Cargo

• cut it out
• need a flat, thin material. Darrel suggested an LP - that would not laser, but maybe 1/16" routing would be OK

options if current design does not work

• need to figure out the hours part... maybe spiral?
• could do the whole thing with only 5 minute increments and use hour speed

givens

• Clock mechanism
  • diameter hour 5.75mm or 5mm (it has a step)
  • diameter minute 3.55mm
