Welcome to the Infinifactory WikiEdit
Infinifactory -- an engineering game developed by Zachtronics Industries and Alouette Games. http://www.zachtronics.com/infinifactory/
A wiki is a place for spoilers -- BUT the enjoyment of puzzle games is figuring stuff out on your own. Proceed at your own risk. I would personally not recommend going further here until you have beaten all the main campaign puzzles at least.
On the wiki here, try to keep explicit images of solutions hidden behind links so that puzzles are not immediately spoiled at a casual glance.
