On the Subject of The Moon
I’ve waited long enough now for them all to come around; and though the sun may plead and threaten, the moon will stand her ground! So say goodnight to this, the final setting of the sun; tomorrow dawns in darkness. The night-time has begun!
- The module consists of eight “outer” crescents, eight “inner” half-moons, and a center button. Buttons on the same compass point are considered to be a set.
- Four adjacent sets start out lit, four unlit. We will refer to them as “lit 1–4” and “unlit 1–4” in clockwise order.
Find the correct button for each set by calculating a value x as directed by the left table below, then look up its modulo-7 value in the right table.
lit 1 D batteries x % 7 Button lit 2 AA batteries 0 outer lit 3 Digits in serial 1 outer lit 4 Port plates 2 outer unlit 1 Modules 3 inner unlit 2 Consonants in serial 4 inner unlit 3 Indicators 5 center unlit 4 Ports 6 center
Determine the first set to solve by taking the sum of the serial number digits modulo 4 and using the following table.
0 1 2 3 unlit 4 unlit 1 unlit 2 unlit 3
The next 6 sets are determined by the characters in the serial number. For each character, move to the next set as directed below:
0 1 3 5 7 8 A C E G H J L M O Q S T V X Y 2 steps clockwise 2 4 6 9 B D F I K N P R U W Z 2 steps counterclockwise
- The final set is the last set that remains.
- The module will be solved once you have correctly pressed eight buttons or when you have pressed the center button.
