No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Hello,

I'm into microcontrollers and programming and would love to send my own small cube satellite into space (one day).

But there are a few things I have zero experience with, and these are:

  • When the satellite is in space, it needs to correct its position to always point the camera on earth
  • During launch of the rocket my cube sat needs to be as robust as possible
  • I can not manufacture the case myself
  • Power supply + battery
  • Providing in-orbit (OTA) updates - This needs to be bullet-proof working
  • Space RF communication protocols and best-use technologies - I need to read about it more
  • Software security best practices in orbit
  • Suitable ground station hardware
  • Which deployment orbit
  • Deployment mechanism
  • Radiation-hardened MCUs and SBCs - Which models? I just know consumer models like ESP32, STM, Raspberry Pico, Arduino, etc.

Can you recommend a good read on that? A book or pdf? Is there anyone with experience?

(This project is btw on my bucket list before I die, it's not urgent though)

Best,

I've seen someone doing it but it was not a small cube, it was more like a small box cube. And they used rotors (like in a phone) to adjust the cube in space. Thank you for the link!
