I wanted to try and see if we could bypass the door entirely, and that’s where the canned air comes in. If you turn a can of compressed air upside down, it starts “boiling off cold gases.” These are not harmful in open spaces, and their temperature is well below freezing point even when gaseous. This can trigger a sensor that checks for temperature increases: First it sees a drop to -50C, thinks “Baby, it’s cold outside.” Then, the temperature starts rising again, and the sensor thinks “Oh, temperature going up?! Must be a human!” and opens the door. If this works, I will update my Mastodon. If it doesn’t, well I can still walk in after someone, so it’s a finding nonetheless.
