Lightning Controller

The Lightning Controller is a machine added by Environmental Tech. It is used to make the Lightning Rod multiblock, which can generate massive amounts of Redstone Flux from lightning strikes, and comes in 6 tiers.

Generation
Every to  ( to  during a Thunderstorm), the topmost Lightning Rod has a chance to be struck by Lightning. When that happens, a random amount of Redstone Flux is generated and stored in the Lightning Controller, which can be then extracted from the bottom face.

The stats of each tier of Lightning Rod are as follow:

Construction
All structures can be built using the Assembler.

Tier 1
The complete structure is 3x7x3 and requires (on top of the Controller):
 * 3 s
 * 3 s
 * 4 or above

Tier 2
The complete structure is 3x9x3 and requires (on top of the Controller):
 * 4 s
 * 4 s
 * 4 or above

Tier 3
The complete structure is 3x11x3 and requires (on top of the Controller):
 * 6
 * 22
 * 13 or above

Tier 4
The complete structure is 3x13x3 and requires (on top of the Controller):
 * 4 s
 * 16 s
 * 13 or above

Tier 5
The complete structure is 3x18x3 and requires (on top of the Controller):
 * 6 s
 * 22 s
 * 13 or above

Tier 6
The complete structure is 3x23x3 and requires (on top of the Controller):
