Late-game beaconed science lab blueprint that loads the belt in a consistent rainbow pattern.
Consumes a little under 300 science per minute per tile with full lab speed research (for 60 second / 6 pack research). Two combinator "latches" are used to synchronize the release of packs - if you're feeding in less types of packs than all 7, adjust the combinator set to N >= 28 to 4x the number of packs you're feeding it (N >= 24 if you're feeding it 6 types but no space science, etc).
Tilable (overlap the power poles and beacons with the next row, see image below) - 9 copies should be deep enough to consume a full blue belt of every type of science (2400 SPM).
