Single digit seven segment display. The four lines on the left represent the binary (0000 to 1001). Each segment (4 power shutoffs) has its own smaller control circuit. Sorry for the messy layout. This version uses 40 logic gates but could potentially be optimised further.4yr ⋅ BnBshp ⋅ r/Oxygennotincluded
How to do 4x4, 5x5 or bigger bridge crossings. Top left is a 2x2 four-bridge repeatable unit that tesselates to make any size bridge crossings for liquids, gases, conveyors etc. The bottom left shows how to extend the crossings by 1 to have 3x3, 5x5 etc. The black lines are connections.5yr ⋅ BnBshp ⋅ r/Oxygennotincluded
