-pipes can cross cables at 90 deg
-pipes and cables can occupy the same voxel as long as their ends dont intersect.
-existing pipes and cables can be "upgraded" with more outlets (i.e. a straight into a t-junction) as long as the appropriate tool is in the off hand.

Visible resources on the ground account for abour 20% of the average size of resource pockets. I keep one hand on the tablet, and cycle GRP and drill in the other hand.

They make for good beacons when trying to find your base in the dark as long as one is on an exterior wall with no obstacles in your LOS.

Emergency battery backup for the downstream circuit, and reducing the amount of clutter when you start to make circuits. Upstream circuits will not see downstream and vis versa. Transformers are low-tech APCs for this purpose.

You just don't get to enjoy the hotkey. A mining belt must be in the belt slot, however, to mine straight into it.

Aside from broader light, it effectively doubles your suit battery not having to use your headlamp.

Popping in a drill battery beats waiting until sunrise or losing atmo.

...with a single N2 filtration unit.

Use a backpressure valve (~50MPa) to loop pump output to input. Tanks are low tech time buyers for mixers.

Mid game can use pipe analyzers and logic read/writer/compare/select simple circuits.

They output 20 kw, and (currently) will just ground 15 of it if you squeeze it through a regular cable. Furthermore, if you don't have a demand of 5kw, it will ground any surplus. Small and regular battery chargers have capped inputs of 1kW and 2kW respectively.

1 battery, and 1 heavy cable will basically solve this - batteries only discharge current demand and have no input cap.

If you just wire doors for an airlock, you can press the keypads to open and close them.
If you wire and plumb active vents, you can create manual airlocks.
If you setup an automated airlock with a console, you can now turn off the console screen and the keypads will perform the "Cycle" function, saving the power you'd need for the console screen.

Also, if you find yourself on a closed side of an airlock, pressing a keypad will cycle it open.

tl;dr: build at least 10 pipes between your active and passive vent if your base pressure is <102kPa

So you've hit bare minimum pressure (20kPa) and can now take off your helmet. Notice the "Airlock" blade demands pressurizing the airlock to 100kPa? Notice that takes forever, (or is impossible if your base is does not have at least 250 mol of atmo)?

This is because the active vent has strong inward but weak outward; but there are a few more game mechanics making this difficult. One is that active vent speed is slow until it hits around 15kPa. Another is that a vent will instantaneously pull from a pipe, but not from it's vented room.

Building the extra pipe lengths creates a starter tank that gets you up to 15kPa quickly, and then the mode 2 vent speed will create a proper in-rush velocity to air entering the passive vent.

Once you have the resources and power to spare, airlock speed can be made even faster with more active vents on the same airlock console, and/or pressurizing your "starter" tank above the base pressure with regulators.

As soon as you get your three benches up, you can make a mini-fridge. Build a fridge kit small from the electric printer, and a gas canister filler from the pipe bender. One pipe segment out the back of the fridge into the canister filter, and plug in your jetpack tank (nitrogen).

This will reduce your initial flight time down to a third, but the tradeoff is a nitrogen charged fridge long before you have an atmo bay up. Stick your starter eggs in here to initially almost double the decay life. If you have a means to cool the nitrogen down (such as pipe radiators on Moon, Mimas, or Europa), this can stretch out to up to 15 hours!

Do not worry about leaking nitrogen by opening the door. The fridges do not work that way. Also, the fridge units and the fillers are effectively insulated.

Press your switch key twice (for me, "F") to send whatever is in your hand to your inventory. If nothing is open, it will go to your backpack. If you have your toolbelt open, a FF'd tool will go to your toolbelt. If you mining belt is open, your mining tool and PDAs will go to your mining tool belt slot.

Also, clear all open inventories with the "~" key.

You get about 3-4 opens in hazardous atmo before your lungs need a pill to restore. A great way to setup a safe space early on is to make a 2x2 dark room, gas it with the oxy tank, and start growing mushrooms. By the time you are back due to thirst or hunger, the temperature will not have gone hay-wire enough that you can't make manual adjustments. Just don't forget to turn off heaters or coolers before you leave!

"i" to open and close once the helmet is unlocked.
