Is there a way to change the target pressure of the airlock circuit board?

[Meme Rights Activist]

I can get a basic airlock to work, but its target pressure is like 100kpa (?), which is fine, but takes WAY to long to build to. So, what can I do to change it to a more reasonable number?

you can use a powered vent. thats the big vent. a 1x1 airlock is very fast with that vent. i use a small utility tank instead of the passive vent. https://steamdb.info/patchnotes/11825444/

Use the Advanced Airlock Circuit Board and you can set the exterior and interior pressure when it changes doors.

Some say adding more pipe pieces on each side of the air lock will allow more volume in the tube to assist with filling up the airlock.

Cows are Evil on Youtube has some good videos that use IC codes.

Put a configurator cart in your tablet to see the current settings easily, wire up a dial, a reader and a writer to manually set the target pressures however you like. External is the vent face, internal is the pipe and whatever it leads to.

when you put the data disk in the console and turn it on, at the top are your pressure settings. You can set those to whatever you want, but keep in mind that when the airlock depressurizes, all that atmosphere is transferred into the pipe, and if you're not pressurizing to the same level the pressure in your pipe will slowly build until it bursts or you vent it.

On the flip side, if there isn't enough pressure in the pipes to pressurize the airlock to the set level it will just hang there. The kicker is there is a tendency to over pressurize slightly - especially when the external is low, like 2kpa on Mars - so you end up slowly losing pressure, and have to charge the pipes by skipping some pressurize cycles. I've solved that on some custom airlock designs by adding a vent to maintain a certain pressure in the pipes, but it happens slowly enough that it isn't a big deal in a small airlock.

The default airlock design is soooooo painfully slow, making it faster was the first thing I did once I figured out which way was up. The issue is the default airlock boards only allow for one external vent and one internal vent, but there are a couple of ways you can add more:

1) Use a combination of logic readers and batch writers, one pair for power and one for mode. This requires some fancy wiring that will spill out, and you'll have at least one cable dangling out to connect everything. You need to connect the input side of the reader to the actual airlock vent, and the output side to a batch writer. The batch writer must be on it's own circuit with the mirror vents. To do this for dual direction requires 2 such circuits. It gets a bit messy, but it works, and I can tell you that 6 powered vents instead of one are soo much better.

2) The easier way is the use an IC housing and chip. You can connect everything to the same circuit, so it doesn't have any of the same logistical concerns. Basically, use the labeler to mark one vent as "Int", one as "Ext", and however many more you want as "IntMir" or whatever twists your nipples. The script is pretty simple, you just have to use the batch name commands to get the power and the mode from the "Int" vent and write that out to all the "IntMir" vents.

Might look something like this:

define pvent <add the hash here, it's available from the F1 menu>
define intVent HASH("Int") # or whatever name you used
define intMir HASH("IntMir") # or whatever
# define your externals here
alias res r10
Main:
lbn res pvent intVent On 0 # this loads the on setting into res
sbn pvent intMir On res # this writes the on setting to the mirror vents
# Add more for the Mode, and then another set for external vents
End:
yield
