+1 for frigate. I have some old V2 wyze cameras with openmiko for rtsp functionality.

Fucking gold!

Solvespace

Watch a few of these to get started, skip ahead as needed. It’s got some limitations but leagues ahead of freecad in terms of UI and workflow.

The existence of foss projects should never exclude the creation of alternatives if someone wants to try.

Try solvespace. Freecad UI is a mess. Hopefully they fix it one day.

Wow. Thank fuck I love somewhere where unions are an accepted and appreciated concept.

I think this is rather location dependent. Here in Aus a lot of people I know use them. Just some more anecdotal evidence.

Pretty much this, look up Kalman filters if you want details. The most likely explanation is that they are tuned to effectively trust GPS more than the internal IMU for long periods of time. Really good IMUs are very expensive and still drift but have high speed output. When it works well, GPS is cheap and doesn’t drift but with a slow update rate. The cost optimisation probably means that the IMU data is usually only trusted for a few seconds, probably 10 min at most before it takes whatever the GPS says as truth. If they lost gps signal through jamming, then they would keep navigation on the less certain IMU data, but the GPS sensor thinks all is well so they shift position.

There is probably a software upgrade to the filter that could be used to limit these attacks, but I imagine it’s an active area or research.

I can’t see how omega and similar were not just as susceptible to this type of attack. Active outside in positioning almost always has this vulnerability.
