  • I think the idea of using coarse grounds for the French press is mostly for filtering out the grounds with the steel mesh on the plunger. If you have a finer mesh, by all means, go for it.

    I’ve also seen some of my fellow coffee lovers at work use filters wrapped around their press, or using an ultra-fine metal mesh on their air press. They’ll go for a finer grind, and it definitely helps the brew steep quicker.

    Personally, if I’m using a glass press, I can usually tell the brew is done by jostling the pot and seeing if the grounds sink. In my metal one, it’s usually 5+ mins, and then it’ll jostle and test the resistance with the plunger to see if the grounds sank.
















  • First, they have to align on the ground. You initialize them with your current known position (usually by GPS or your known airport/gate spot). Then, you wait for them to synchronize with the Earth’s rotation. If you’re far north, like in Alaska, this could take half an hour. If you’re close to the equator, it could take 5 minutes. Once they’re ready, from that point, any movement you make, it will know where you are and where you’ve been.

    If you spin up a gyro and begin moving around, it will maintain it’s starting position. You can use this deflection to calculate direction. If you know how fast you are going and for how long, you’ll have your position.

    Mechanical gyros drift. It’s the nature of a world with friction. Newer IRUs use laser gyros, so the only real drift they have comes from extremely minute rounding errors.
