[Power/EMI] I discover why sometime PC become fast and low input lag and otherwise feel high input lag

[Chief Blur Buster]

Although you're right about the inverters, there's no measurements that I'm aware of that show that it's not enough to affect a computer. I mean if it's far away it's probably not an issue but if it's literally right above you, I'm not too sure that I'd take the chance.

FALSE.

Reason: Blatantly Obvious Law of Physics (if you ever went to any Unviersity).

Solar is DC power, and DC power is incapable of generating harmonics necessary to generate inteference.

You're saying something like "There's no way to prove the sky is blue".

It's University 101 stuff.

(Added note: I'm ignoring literally subatomic noise such as quantum noise / blackbody noise -- not even a blip of measurable error margin when we're talking about literally the sun blasting 10^17 photons per second per square centimeter of solar panel at 1AU earth distance!)

Now, if you turned ON/OFF the sun very fast (like a light switch), you can generate harmonics in a solar panel. But the sun shines steadily, and usually fades slowly (clouds). Only the power state changes are the harmonics-generator, and those power state changes are slow.

I honestly skimped over the DC part. I'm very aware of this. My fault

[...]

I'm also not educated enough on solar panels, I've just seen some cases where it's an issue. I'm sure everyone's setup is different.

Definitely. Some of the worst electricity I've seen has come from crappy/defective inverters.

Even a plain UPS can have a very bad inverter built into them too.

(An inverter is those circuits that converts DC to AC. They're found with both UPS and with solar)

Hello.
I am thinking about buy a quality inverter and battery(12v 200ah for trucks) but electrician guy said to me if u use SMPS charger for battery
it will have no meaning. For battery charge should use isolation transformer or clean electricity source but i didnt try it before.
Best way for me buying inverter and battery but did someone try it before?

Hello everyone,is it possible to write only in English?

Hello everyone,is it possible to write only in English?

The language of choice on Blur Busters is already English. I didn't see any foreign-language posts in this Blur Busters thread.

If you meant are using a translator to read Blur Busters and the translations are messed up --
I need to remind you that writings on BlurBusters are very technical and doesn't always translate very well to English. There's usually a lot of translation errors when it comes to terminology used on Blur Busters. We're still writing English, it just doesn't translate very well to other languages because of the highly technical BlurBusters terminology.

If you meant things are too technical and need people to write in simpler English --
That's just the way Blur Busters is. We do try do the middle (Popular Science style) between kindergarten and complex science journals. Bringing advanced concepts slightly more mainstream.

Hi everyone, I'm from Russla.I will use a text translator there will be a lot.There is an apartment in the city, the wiring there is aluminum, old,there is a router in each apartment,the wires in the shield are like spiders, respectively, I have the same problem of high inputlag on the game monitor.there is a private house,the wiring is perfect,the grounding is clear, I made the circuit myself,I came to measure the resistance everything is just perfect,but here it's the same with games..I tried everything, nothing helped,even ps4 pro behaved very strangely,and there was no assist in the games at all and the picture was sickening,I lost in all online games, I couldn't even kill opponents in the back,it seemed that the game was 2 seconds behind.I bought a ups online, set it up to clearly 220 (we have 220 in Russla) and played a frequency of 60hz, it seems better, but still not that the game is lagging behind,I took a tinted hdmi on it, put ferrite filters on it again a little better,but still the game goes wrong, I read about a Network filter 3 m Brennenstuhl Premium-Protect-Line 60 000 A, 6 sockets on some medical site that it helps from interference, as a result, I bought it.I placed a ps4,a TV,a router and an Internet terminal in it,you won't believe it for 3 days the game is going well and there is a massist,the trick is certainly not the same as that of streamers,but I have one provider I can't experiment,but the fact is that I now shoot opponents 1x1 and the picture has become productive, smooth, I hope that this will remain forever, I almost forgot I didn't use ups when playing,only this network filter,I hope that it will also help you.I have returned the desire for cod warzone and other games, good luck to everyone,sorry my langvige

what do you mean about network filter? is this surge protector with emi/rfi but when i test some filter, didnt help me. Can u just use pc/ps4 and wont plug your modem and write results pls?

I think you can build solar system for much cheaper

- 180w Solar Panels are around 150 € each you can find it even cheaper if you search more
- Controller 15 €
- 300w Inverter with pure sine wave 150 €
- 100Ah AGM deep cycle battery around 100 €

Yep, I agree. However, it's not an overnight fix -- you can get a Jackery with Amazon Prime shipping and be offgrid tomorrow.

Also, it is illegal in some jurisdictions to DIY electricity without taking a class to certify you as an electrician first (e.g. you have to use a licensed electrician in Quebec, Canada). The Jackery doesn't require you to be a licensed electrician.

Mind you, it is legal in many countries, if you know how to DIY electricity (things like installing a new power outlet, or a new circuit breaker), definitely consider it as a possible option. Where I live (Ontario, Canada) it is legal to do basic DIY electricity like that, as long as you buy proper rated parts (e.g. CSA / UL listed, etc), and I've done a few wiring jobs myself (not for offgridding though).

Thank you chief i would also like to add that a simple am radio that costs no more than 15 dollars can confirm if u have interference or not (it will sound very staticy) before u drop a k on this u should at the very least confirm wether or not u have an issue with interference

Caveat: While an AM radio can be a tool for testing EMI/EMF, sometimes there are bad electricity waveforms like distorted AC-crossing events (squiggly sinewave) that sometimes aren't easily diagnosed on AM radios. There are billions of different ways that electricity can go bad enough to create issues with a computer -- that don't have any effect on AM radios. Some stay-on-wire EMIs don't emit strong enough interference over the air to make an AM radio notice amiss. But if you *do* hear really weird sounds (other than a normal AC buzz) with the radio near wires (but away from other gadgets), then it's certainly one of the many legit redflags you can to add to the redflag list (sometimes you need multiple redflags to reliably diagnose).

That's why it is almost impossible for most average users to reliably troubleshoot. The professionals use many troubleshooting methods, like wide-band oscilloscopes and waveform monitoring / logging (as the waveform can distort at different times of the day -- e.g. nasty harmonics during evenings only, or during daytimes only, etc). Even that doesn't catch everything, unfortunately.

However, if you notice your latency drop massively when offgridding (I've heard of reports in multiple tens of milliseconds), then you only care about the result, and just did a very easy brute-force troubleshoot by temporarily running offgrid off a UPS. So buying a cheap ~750 watt UPS (short duration power) and then unplugging the UPS to test for 5 minutes of offgrid, to see how latency behaves. That can be another troubleshooting method; using a much smaller UPS.

3 hours is rookie numbers. For some it might be electricity, for some RFI. There are different experiences, but noone yet locked any of it for long enough time to tell if it is fixed permanently.

Suuuuuuure, yes it is rookie (not the point), but it's easy.

For a $1000 budget it's hard to get more than 3 hours. To someone who rents an apartment/dorm, $1000 is a lot of money but not as expensive as, say, a Tesla Powerwall style sytem. Or even the knockoffs at half those prices.

If you can increase your budget and do lots more work, and get a real Tesla PowerWall style installation -- then the sky's the limit.

However, it's an easy $1000 quick-solve that is 100% apartment rental compatible and 100% landlord safe for a student dormitory.

One Amazon Prime shipment later and you're offgrid instantly without rewiring or custom setups. It's not much gaming time, but if you cannot spend more than $1000 and you live in an apartment/dorm/etc... It's a way to (semi-inexpensively) go offgrid even in a student dorm this way; which is the precise point -- it's a landlord-safe method of offgridding.

A more advanced DIY solution: You can buy up a few LiFePo4 batteries, plus the necessary inverter/charge controllers -- and wire your own apartment-friendly DIY setup at a bigger wattage (2000-3000 watt-hours) for less per watt hour than a Jackery. If you don't mind waiting 2-3 months you can buy off places like Alibaba and get it shipped by a freight forwarder (ala slow boat).

And could be great if you live in certain countries (China) and have access to cheap domestic LiFePo4 battery packs, which are much safer than Li-On or Li-Poly batteries. But LiFePo4 battery packs sometimes look industrial or looks like ugly car batteries. And starts to become an industrial size/scale a landlord may frown on, unless you box it up in a nice innocent casing/pushcart/etc that blends in your place. But, this would be your route if you didn't mind a roll-your-own DIY solution rather than a rookie solution.

LiFePo4 = Lithium Iron Phosphate
- Very cheap at only a few hundred per kwh!
- Heavier but Safer (ideal for offgriding)
- Doesn't catch fire easily
- Tolerates deep cycling
- Does more charge-discharge cycles (thousands!)
- No conflict minerals

Middle Option: 5 kWh generic clone of "Tesla PowerWall" for ~$2000-$3000 for all-day gaming

You can get approximately 5 kilowatt-hour lithium battery (cheap Tesla PowerWalls for you!) for only $1500 from Alibaba and Aliexpress including an inverter. Then add the freight shipping as necessary. 5000 kilowatt hour is enough for about ~12 hours of RTX 3080 gaming even with an 55" LG CX OLED.

Generic clones of Tesla PowerWalls now exist with LiFePo4 batteries, if you import them from a country such as China. Do make sure you double check they are the safer lithium batteries.

You just need to do but you're going to have a very jump-the-hoop ordering experience (you have to communicate to them like a business, be patient, because you're buying 1 sample from a company that usually sells them in quantities of 100 or more), and being heavy units, freight shipping is slow rather than 1-day Amazon Prime that you can get a 1000-watt-hour Jackery Power Station literally overnight.

But yes, you can build your own cheap 5000-watt-hour "Tesla PowerWall clone" system for your computer room for only about $2000 if you have enough electrician DIY. Basically a one-room-only "DIY PowerWall on Wheels" that is landlord-safe, for all-day offgrid gaming. This is a bit overkill if you're only 50-50 sure it's your electricity. You'll need to buy a cart and make sure these are very safe lithium chemistries that won't catch fire -- LiFePo4 is what I would recommend for offgridding, as they resist deep cycling (charge-discharge cycles).

Mind you, sometimes it's just easier to test with a Jackery first (smaller investment, quick test), or even a cheap low-watt-hour 750-watt-sustained UPS that gives you about 5 minutes of playtime for offgrid testing's sake.

there is out there a power station with more power ? 3 hours for me is short time hehe

If you want to spend more money and/or more time, definitely yes.

You can build your own "Tesla PowerWall" clone for about $2000-$3000 that gives you all-day gaming from even an RTX SLI system.

(IMPORTANT / DISCLAIMER: SEARCH EXAMPLE, NOT AN ENDORSEMENT, I DONT KNOW IF THIS IS ONE OF THOSE "SAFE" ONES)

These chinese bazaars add things like "tesla powerwall" in their names, even though it's just a cheap clone using chinese-made LiFePo4 batteries. While some chinese batteries are really safe, others have their risks. Do your research, test/inspect, check factory certifications, check ratings like UL/CSA (some are faked, some are real), and get safety precautions. Also, some of them have crappy cheap inverters that generates a lot of interference. Also, you will have to be your repairperson (can't easily money-back). Do your homework!

gotcha thank you you are the real goat! i know that input lag sounds like something false but it really is depressing when everything goes wrong in my case I have lost even the desire to play seeing people trying to help is really wonderful
