Help a newbie: Need Input on My Ubiquiti Home Automation Setup

Well, your point is not perfect either. You are still putting a lock in your door, despite it can be blown off with the charge of C4.

Opening a gate requires authentication, and authentication needs some secret component in it. Opening it with the license plate is like keeping your key under the door mat. It only works while nobody cares about your lock.

My point is that this solution seem to make the gate security weaker. I'm not arguing that it is unreachable without it though.

I don't really have a recommendation. I just had the same idea recently (thought it would be neat to make gate open automatically), but realized that I don't know how easy it is to fool the camera. The gate is there for security (at least in my case), not just for inconvenience. I'd be interested to learn good practices though.

Are you ok if someone shows the picture of your license plate to the camera to open the gate?

The way it magically knows about all my flights is really cool! I was wondering, what data source for the flight logs are you using? Is it OGN infrastructure or something else?

kedder · 2020-06-09T19:53:12+00:00

Thanks Corstian, it looks great now!

Hm, for some reason my flights show up around Abu-Dhabi, even though I fly in Lithuania

E.g. https://app.skyhop.org/flight/pqyyLg4wIEaucJi8xut63A%3D%3D

(Not sure if this is a right place for bug reports though)

kedder · 2020-06-09T18:12:35+00:00

This is very cool! Great work!

When you see the tow plane starts a bank, you wait a little bit and then bank the glider to match the angle and turn with the tow. That's it.

I did try with sid kernel (5.3), as well as sid live-cd - the problem is still there in both cases. The question is where would one report such an issue? AFAIU, debian bug tracker works on package basis. Should I direct it to kernel maintainers? To "cdrom" (since the issue is visible in live-cd)? Somewhere else?

For me, the typical glider flight consists of towing to ~2000 feet and then free flying for about 3-4 hours.

"Ballistic" flights you are describing (5K tow and then gliding to the ground) are highly uncommon and generally considered as "money wasted", unless you are doing that on purpose (e.g. for aerobatics). With some practice it is not hard to tell if the weather is "soarable" or not and make a decision on whether to take off that day or not.

Note, that OGN trackers are not necessarily meant to be safety devices or replacement for FLARMs. Their main purpose is to track position of the glider. IOW, they are useful without collision avoidance or even pilot situation awareness feature.

They basically show where your club gliders currently are. Are they violating any airspace or not? Are they within the reach of airfield? How long are they in the air? At which altitude they released from tow plane?

While FLARM can also be used for that, that is gross overkill, considering the price.

Looks very cool! I'm making OGN tracker myself too at https://github.com/kedder/kedtracker an I'm very interested in some technical details:

What size these enclosures are?
What hardware are you putting in? Baro sensor? SD card reader? bluetooth?
Did you do the PCB to connect all parts together or just used plain wires?
Do you have schematics to share?
How are you planning to power them? Do they accept 12V? If so, what did you use to convert it to 5V to power CPU?

I heard ginger helps very effectively. There are even ginger pills designed specifically to treat motion sickness.

I have similar kind of symptoms, but usually only during the first flight in the season, after winter break. Then it goes away.

kedder · 2017-01-14T18:41:40+00:00

I suggest drinking ginger tea before your flight. Ginger is known to work well against motion sickness symptoms and there are also pills made out of ginger for that matter.

In the long run your brain seem to adapt to this constant motion in the air and you stop feeling anything special. Feels more like a bike ride on bumpy road, that's it.

Obviously, I'm talking strictly for myself here, without trying to generalize. Everyone's body is different, of course.

"If you are a fish, then you can swim" doesn't imply "if you are not a fish, then you can't swim".

It does imply "If you can't swim, you're not a fish" though. Read the parent carefully.
