I’m pretty sure the MEMS 9-axis compass / accelerometer / gyro in my phone, that also senses temperature, pressure, and humidity, would have something to say about this being the first since 1936
I’ve used a few compass and I’ve never had one take 90 seconds to settle. He’s a cool compass nerd but c’mon.
I do like that it’s got a clear baseplate and no fluid though.
It’s kind of a disingenuous comparison in the video, but I understand why he did it. The one that settles slowly has no dampening, either fluid or an inductive plate, because he set its initial position by hand. Can’t really do that if it’s in a fluid, although he could have compared in other ways, like setting the initial position with another magnet or comparing to another induction dampened compass and emphasizing that you can see through his.
I don’t think it is disingenuous. First, it does have fluid, air. It doesn’t have liquid but he mentions that liquid is a great solution but with other drawbacks, like problems with temperature change.
But yeah, he is intentionally showing a dramatic example of the improvement of eddy damping, but it isn’t to mislead, rather to highlight. He released it to public domain, so clearly not trying to mislead to sell.
