No Stupid Questions
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.

The (for lack of a better phrase) flicker from led lights. For those that don't know what I mean.. Stand near a strobe light and move your hand in front of your face. You get basically a shutter effect.
That's what I see when I'm near led lights and there is movement . It's hard as hell on the eyes.
I wished every one saw it so it would get fixed.
I should have bought a pallet of incandescent bulbs when I had the chance.
The kicker is, this isn't even necessary. It's not LED lights that are the issue, it's poorly-implemented dimming of LED lights.
In some cases (home lighting dimming), you can either buy a dimmable LED light or buy a dimmer made for LEDs.
But sometimes, it's just built in to the device, and there's nothing you can do about it. All it technically takes is a really simple circuit that adds capacitance to the line.
If you have a cheap strip of LEDs dimmed by a cheap PWM controller, you might even be able to just take the positive and wrap it through and around a ring magnet multiple times. I'm not sure that would work, but I've seen it done before for noise filtering, which this is, effectively.
What that does is averages out the highs and lows, significantly reducing flicker. There are some devices out there that do the (small amount) of work that is required not to flicker. It's just.. ..dimming by flicker is really easy, and if a manufacturer can save a few cents at the cost of quality, a lot of them will.
You are describing an inductor not a capacitor. They can be basic low pass filters but I don't think they will work in this case.
I wasn't sure that, specifically, would work. But, the thing with the capacitor does work.
Looks like an inductor does work, but has to be fairly large, so isn't worth it, particularly with cheap capacitor solutions available.
A variable resistor would do a perfect job and still be very low cost. Some high quality LED lights do this, but it is rare.
Neat! I'll have to read up on those.
Fluorescent does this too. I do miss the light of incandescent bulbs but the more expensive led lights seem to flicker less. Some manufacturers make bulbs that are specifically flicker free too.
Do you have any name brands?
Phillips is the first that come to mind. You're going to be looking at paying more on the realm of $15 a bulb. It's a pretty big jump, if light quality bothers you though it's a good investment.
Thank you
Phillips really is the way to go. You can get different color temperatures, smart bulbs, and 'vintage' bulbs all flicker-free.
Older lcd and plasma displays used to flash yellow when moving my eyes around the screen. People thought I was taking crazy pills.
