Old school YouTube here. Short niche content, no clickbait or algorithm pushing. Nice birds, love it. I feel like you haven’t been able to browse and just watch simple original content like this since 2015.
My only complaint is it’s three pages down on videos.
+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.
DOIs or GTFO
It’s not easy but you can correct the atmosphere. This is done with guide stars and adaptive optics.
The bigger challenge is that for intense pulsed lasers, the standard laser profile causes them to self focus in air through nonlinear effects. To overcome this you need to make weird profiles like top hats that are much hard to get just right.
This is a fundamentally physical limitation that is pretty tricky to overcome.
The pure joy of putting a single joule of optical power into a sub nanosecond pulse.
For those not familiar with lasers, that’s a GW of instantaneous power that you can focus down to a micron sized spot.

All that said, the successful laser weapons right now seem to all be anti drone/aircraft and they are typically using tracked CW (not pulsed) lasers with heating over time to avoid atmospheric lensing. Lots of challenges to overcome in getting pulsed energy a long way through air.
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.
I’m not an expert in this stuff but my whole life I have been told to avoid eating mammals that primarily eat meat. Eating a fox just seems wrong, especially when there are so many good to eat rabbits.
If you have a bunch of v2s try this. https://github.com/openmiko/openmiko
Plus you can flash wrt to a lot of the TP-Link stuff including the access points. I haven’t looked in ages but I remember that most or all ubiquity stuff was locked down.
Purely anecdotal but in my experience unify is overpriced garbage. Had a dream machine die at 13 months and could only get an, it’s out of warranty, buy a new one response. Looking at the internals it was pretty clear they were never designed with any service in mind.
They also force you into plenty of cloud bullshit. They lost my password hash for my local device because they fucked up some cloud transfer. If I didn’t have an SSH key I would have been screwed.
It takes a bunch of time and tech know-how but foss has been a much better solution. Have a openwrt pi4 router, truenas server and switched my Wyze cams to openmiko firmware. Far better than anything offered by these prosumer companies.
+1 to this. A steel frame 90s mountain bike with 26" wheels, some maintenance know how and about $100 in parts will get you thousands of km of riding with much less trouble compared to a fancy aluminium/carbon frame with hydraulic breaks and a drivetrain that locks the moment something goes slightly out of tolerance.
Only caveat is needing to buy some tools, but good tools will last.
