OD-O2: On Demand O2 System by Tapper Tech

Nice one!
I've got a few suggestions:
- You can use a 3rd regex with "\b(0?([0-9]|[1-4][0-9]))\b" and constant 1/0 output to trigger an O2 alarm if the generator doesn't work and it falls below 50%.
- This can be easily adapted for a flooding alarm. Connect the signal outputs of water detectors in a similar way, and a regex with "\b(1)\b" basically becomes a universal OR-component.

Also, I think you can get away with using even fewer components if you use comma separators for the concatenations, and connect the last input to a detector as well (instead to the constant 0). Still need to test that myself though.

Very creative use of regexp! Interesting way of merging groups from color components.

When I came to idea of combining outputs of several oxygen detectors to one control signal for generator I instead made all crew compartments doors on the sub to open when generator is off (hence having to deal with only one detector), and releasing the "open override" when generator is on (+ short flood override to make sure all doors will close if flooding is detected).

Great work! I really like this mod, very few components and ingenious use of color components.

creative idea, simple , and well executed (i haven't tested it but im trusting that this functions as shown)
