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.
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.
