Thank you for this.

Also small world, floating point JPEG person here.

Three appropriately spaced antennas will give you azimuth and elevation of a ray to the transmitter, but not distance.

But using two of the above in different, known locations would allow you to compute the intersection to a 3D location.

If you want to get really spicy, you can use two antennas and an SDR to compute angle of arrival using nothing but a BLE advertisement's data . This is different from BLE AoA as it doesn't require a cooperative transmitter.

You could use the BLE AoA extension as well to derive an angle: https://www.bluetooth.com/blog/new-aoa-aod-bluetooth-capabil...

You could mount one at each corner and use a directional antenna to help.

Why did he take the stand at all?

When I first learned about X forwarding we had a modem, and X was responsive. I also played CivII over remote desktop and it was...less responsive.

With Wayland, have you tried out waypipe yet?

I think the worst offenders are the ones that use the measurement circuit to detect if you've started a measurement while the display is off.

An LR44 supplying 15 microamps will last more than 9 months before depleted. This base level of current draw obviously matters to different users differently.
