Look into using Arduino Proxy analog input to read pressure

Could avoid using DAC

Idea: I think some Teensy have the option to have a SD card. Maybe we could turn the IO Proxy into a "mini sensor-suite"? We could potentially record a high data rate to the SD card, and update the RPi less frequently. Just an idea, I don't think there is a need right now for that.
