Не выдержал и заказал один DJI O3 Air Unit, посмотрим :)
FPV-квадрокоптер это летающая платформа с камерой. И эти контуры более менее друг от друга изолированы: можно снять всё, что касается видео, и по-прежнему будет летать и нормально управляться, правда, пилот не сможет ничего видеть.
То есть там полётный контроллер со своим радиоприёмником, отдельно радиопередатчик и камера для видео, и ещё почти всегда ставили отдельно камеру для съёмок — просто прикручивали сверху GoPro. С полётным контроллером и его радиомодулём всё хорошо — научились делать очень круто, работает чётко, опенсорсная прошивка, отличная дальность.
А вот у видео были проблемы. Долгое время оно было вообще аналоговое, но пришла компания DJI и кроме собственных отдельных дронов стала выпускать Air Unit — модульную камеру с передатчиком, которую можно поставить на фактически любой дрон. При этом видео цифровое и передаётся только в очки от DJI.
Это был отличный ход: качество у такого видео лучше, чем у аналогового, поэтому FPV-шники стали массово скупать очки от DJI, китайские компании массово приобрели у DJI лицензию на выпуск своих модулей с их чипами (Caddx, например, она у меня на одном из дронов стоит), на аналоге остались разве что дроно-гонщики, там слишком важна задержка между картинкой и реальным временем.
Но потихоньку стали появляться решения от других производителей: например Walksnail Avatar — тут тебе и очки сразу и видеомодуль. Сами DJI выпустила новые очки, оказавшиеся несовместимыми с Air Unit. А ещё они же релизнули FPV-дрон Avata, который хоть и хороший, но не даёт той гибкости, которая нужна крутым (и не таким богатым :)) ребятам. Казалось бы — ну всё, лидерство DJI в области видеопередачи для FPV-дронов постепенно заканчивается.
А, ну и параллельно с этим всегда была проблема "на что снимать?". GoPro очень тяжёлая. А всё, что лёгкое — не слишком качественное. Сами GoPro выпустили версию Bones со снятым всем подряд, кроме самого необходимого. Ещё активно делали (причём, как люди сами, так и фирмы) так называемые GoPro Naked — разбирали камеру, выкидывали аккумулятор и экран, печатали новый корпус полегче.
И тут бац тебе: O3 Air Unit. Это камера от DJI Avata с видеопередатчиком, которую можно установить на любой дрон. Качество на голову выше, чем у всего, что есть на рынке. Достаточное, чтобы на эту камеру даже можно было снимать, а не только смотреть, куда летишь. Совместимая со всеми версиями очков. Решает сразу очень много проблем. FPV-шники теперь ещё больше будут покупать дорогущие очки от DJI обеих версий. Вишенкой на торте ещё и идёт тот факт, что камера впаивается, то есть ты её так просто с одного дрона на другой не поставишь. А у летающих ребят обычно по 2-3-5-10 дронов. Ну, экономику считайте сами. Гениальный ход, как по мне :) И очередной Game Changer.

As we continue to live under increasingly dystopian regimes, the need for secure communications is more vital than ever. Telegram has been a great resource and platform for disseminating information and content, but it certainly isn't perfect either.
Some research was done into which digital communication protocols are most ideal for our purposes:
https://telegra.ph/WEbHqRllMIfQa5YzpTSJBrNxfo6tu9-Digital-Communication-Protocols-09-08
The top picks are as follows and are in no particular order:
XMPP
NextCloud
Jami
Briar
Tox
Kontalk
Delta Chat
Bitmessage
Ricochet
Status
Scuttlebot
Session has not had an E2E audit completed yet, but not a bad choice
ȱ
Protocol for SYnchronous Conferencing (PSYC)
Matrix is not recommended: https://www.hackea.org/notas/matrix.html
CAUTION: peer-to-peer communications reveal one's IP address to each other, so using a reliable VPN, proxy, or TOR is advised. Briar is an exception to this rule, as it uses either Bluetooth range or the local network it's connected to; else all traffic goes through TOR. Ones without servers are ideal, such as: Jami, Tox, Ricochet, Status, Scuttlebot, ȱ, and PSYC-2. Some are still in development and may be prone to bugs.
Keep these options in mind when communicating with your clique. Many of us belong to private groups on Telegram which are presumably free from moderator surveillance (or at least interference), but ultimately we should transition to a more durable platform that will be unable to censor our messages. Try a few out and see what works for you and your crew.

#im the editor of this. This is not my own work, made by a friend. Please review
I know you're tired.I know you live with demons ,ones that are loved and close. I know how relentless they are in their pursuit of u...I know you spend your days trying to silence them and your nights trying to hide from them-and the hell they put you through. Most of all, I know how hard u work to hide it all, to pretend you're fine, to paint a convincing smile upon ur face, and to act as if all is well with ur battered soul.
I know that all of this has left you exhausted—that you've numbered yourself and hurt yourself and starved urself in the hope that their voices will become silent and their fists will be lifted and you can finally breathe again. I know that right now it doesn't seems like moment will ever come. I know right now you'd rather leave than live. And even though I'm not standing in your shoes right now, and even though I don't know you, and even though I have no right at all—I'm asking you to stay ...to endure your incredibly painful, totally senseless now because I can see your glorious, blindingly beautiful then, if you do.
If u stick around, u will reach a spot that the sadness won't let right now- You'll reach tomorrow. And that is filled with possibility. It's a day you have been to. It's not this terrible day. There, you will not feel exactly What you are feeling right now...You may be stronger, or see things differently, or find a clearing, and life may look a way it hasn't in a long time. It may look like worth staying for...Tomorrow is the place where hope lives, and I want you to give yourself a chance to share space with that hope- to dance with it, to rest in it, to dream within it because you deserve it...
Dissapointments and regrets are mistakes...And you know there'll be moments of despair and painful seasons and dark nights of the soul you'll need to endure. You'll screw things up and be let down. You'll hurt, and you'll wonder how you'll ever make it through! But it's okay. Giving up is never the solution. Tomorrow will make you better
Instant messaging apps review
I tested a lot & mulled on this for a while.
Our goal was something less centralized, more private & harder to take down or block.
BRIAR is good & with p2p modes to be censorship resistant if internet is cut, but you have to invite each user separately to a group which is a pain
XMPP is archaic & behaves like a traditional one to one messenger. Yes, groups are there but are more like texting groups & you can't tag or reply to anyone directly.
MATRIX is better but ends up being 3rd party centralized because hosting yourself is a hog, which means you're bound by that hosted server & all those rules, giving up your email credentials, getting possibly kicked off, etc. Matrix.org server started requiring email verification for instance.
Matrix doesn't encrypt metadata, your IP is visible to others in chats.
The last 2 require a hosted server somewhere for large groups to function properly, and so does SESSION since it too has no servers of it's own. But its way lighter than Matrix & can be hosted on a mediocre VPS (which I've done, I can pay, its cheap its fine). The added benefit of Session is everything is onion routed automatically, and there's zero identifying factors when creating an ID. No phone numbers, no emails, nothing. Restore that ID on a new device using a cryptic passphrase, or start a new one if you want.
Check out @Nogoolag room with SESSION:
