This is a unique double-pendulum lottery machine

As is well known, the motion of a double pendulum is highly unpredictable; even minute differences in initial conditions can lead to dramatically different outcomes.

Based on this principle, we have designed a double-pendulum lottery machine.

Its winning probability consists of two components: the reading zone (the red circles in the figure below, with four reading ports) and the color ring.

Winning scenario 1: one zone, with colors that can be customized—white, black, or red.

Winning scenario 2: two zones, with colors that can be customized—white, black, or red—and corresponding prize tiers.

Winning scenario 3: two zones with contrasting colors—white, black, or red—and customizable prize tiers.

Currently, the color ring is interchangeable, and the reading zones can also be swapped, which opens up a wider range of probability combinations and winning scenarios.

Assembly Components

You will need four bearings with an inner diameter of 5 mm, an outer diameter of 10 mm, and a thickness of 4 mm.
