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.

To start off: I was explaining to my friend that I don't have a grounding point in my house (plumbing is PVC, outlets are gcfi protected only, not allowed to drive a grounding rod into the ground, etc...) and that I've just been handling sensitive electronics with just luck and preparation (humidity, moisturizer, no synthetic clothing, etc...) all this time. He told me to just wire myself to a good, multimeter tested, grounding point in a car and that will discharge any built-up static electricity. I'm not smart enough to argue with him on this subject but that doesnt seem the safest. Would that work or should I just keep doing my method? My understanding is that chassis grounding is essentially replacing wires with the frame so the outcome would just be connecting myself to the negative terminal of a car battery.

Tldr: I'm explaining my lack of a grounding point at home for sensitive electronics and is advised by my friend to wire myself to a grounded point in a car to discharge built-up static electricity. However, I'm uncertain about the safety of this suggestion and questions whether my current method of handling electronics with precautions is sufficient.

Edit: lmao people are really getting hung up on the no grounded outlet part. Umm my best explanation I guess is that its an older house that had 2 prong outlets and was "updated" with gfci protected outlets afterwards think the breakers as well. My understanding is that its up to code but I'm not an electrician. As for the plumbing I'm sure there's still copper somewhere but the majority has been updated to pvc over the years. Again it's not my house I don't want to go biting the hand that feeds me. Thank you though, haha

Edit #2: thank you all so much for the helpful advice, I really appreciate all of you!

This is in the US, yes? Don't they have this two phase system of 220V that offers 2x110V, with ground being the center?

[–] aubeynarf@lemmynsfw.com 1 points 9 months ago* (last edited 9 months ago)

Yes, the center (neutral) is connected to ground somewhere, but is not a suitable ground reference - because current on the neutral creates a voltage drop along the neutral conductor. A North American outlet box has Hot (L1), maybe another Hot (L2), Neutral, and also an earth/ground conductor.

Neutral is not ever treated as ground; it’s impermissible to connect it to any bare metallic surface. Other than not being switched, and being the side that ends up on the threads of a light socket, it’s handled the same way as a hot/line conductor. Just like a 240V system.

It would dissipate static fine, if you were allowed to touch it.
