A live wallpaper clock made using Java Processing

Can run in the desktop, processing-java --sketch=$PWD/OClock --run

The project was exported in processing v3 into android and worked upon in android-studio (java -> kotlin, etc.) So consider OClock/ dir which has .pde files outdated, need to edit the kotlin code.

• nix-shell should work
• nix-shell -A <shell> shells.nix should work
• nix develop .#ci see nix flake show

• build android apk and bundles without android studio
• figure out signing too, prod+debug

Look:

• 0.0.1:
• v0.0.4-alpha:

Info on gear ratio

My train of thought:

• The setup consists two gears and the smaller one is the driver gear.
• Important: only consider teeth not the radii of the gears.
  • number of teeth is proportional to the radius
  • But teeth is the main concern.
  • In this setup is ratio of radii is used it won't look visually correct.
  • whenever I talk about ratio of radii it should be treated as teeth ratio.
• Smaller gear needs to rotate more and fast (always).
• So angular velocity of smaller one should be faster.
• If bigger one roates by one deg smaller should rotate by (R_bigger/R_smaller) degrees.

In case of gear simple chains

• Setup: a(driver)->b->c
• Now gear if a roates by α b should rotate by (a/b)*α thus c would rotate by (b/c) * (a/b)*α i.e. (a/c)*α
• Thus any diven gear rotates by R_driver/R_itself * α_driver
