My understanding is it's the piston and gas, undergoing rapid decompressor.

That's what I understood from the article as well, but commenters below say they fixed it with a cotton cushion. That rules the piston out.

It's possible there is more than one cause. My chair has a super thin, almost no cushion, so it's not the cause here I think.

I played with a negative ion generator at my desk, and it was great at knocking out my 1440p monitor signal, but the 1080p seemed more resilient. Since then I got a 4K display, and it likes to drop out in thunderstorms. I switched to a better DP to HDMI adapter, and the chunky original Samsung cable. I'm waiting for the next storm to see if it helps.

My hdmi cable causes my headset dongle’s range to significantly decrease. From like 50+ feet to 10.

It’s not properly shielded. If you have a multimeter you can do a quick low-hanging fruit pass by checking continuity between the metal shields on both ends. No continuity means no shielding, but the clever assholes will run a thin wire between the shields so it passes that test, even though it’s not actually shielded. That means it won’t tell you if it is shielded, only if it definitely isn’t.

I found a similar issue with nearly all of my cheap USB cables, which I started looking into when I realized only some of them would work right with my camera or Arduino. Out of ~30 cables perhaps 14-16 of them had no shielding at all. I cut open five “shielded” ones and two of them had a thin wire connecting the shields, just to fool people casually testing them. It’s a real crap industry.

When I last looked, the evaporative methods were better than others. You don't need distilled water for it, tap will work. They do need cleaning and frequent disinfecting though due to the pad constantly sitting in the water. The prices of replacement pads are a bit expensive but it was cheaper than constantly buying distilled water. There are a few brands out there but the Philips ones seemed better than the others…

Thanks. I'll check out Philips. I wonder if third-party pads exist. I prefer dumb, but I don't mind if it's smart. Especially if I can integrate the smarts into my Home Assistant rig. I built a humidifier once. I just used the Instant Pot that was already on the countertop. I filled it with water, set it to "Keep warm", and it slowly evaporated the water and left minerals behind. This worked fine (it was safe, if ine…

For truly dumb, Honeywell HCM350W/HCM350B https://amzn.to/4tSEAGy has just a multi-speed fan knob and a hidden UV lamp and nothing else. The 1.1 gallon tank gets through a couple of nights here, current outdoor humidity is 16% on an overcast day in the middle of "rainy" days (high altitude semi-arid). 6 non-brand wicks for $22 will last a long time: https://amzn.to/48EwKbb

Copy that, thanks. The third-party replacement bits look OK-priced to me, I like the idea of a UV light (which is at least simple and safe), and since it's dumb then it's certainly simple to automate with a switched outlet.

I'll try to pick one up before the cold weather comes back again. (Right now, we have the opposite problem for humidity here, in that we have too much of it.)

How long do the wicks last for you?

We have fairly hard water so they get chalky white and crispy in like 2 months or so, but replacing is still a little optional, the wick just starts slowly working less well. Minerals stuck on the wick aren't a health risk or anything like that. The base where the water sits is easy to wash and bleach when you feel like it.

A tip here, if your wick is symmetric you can turn it upside down and get some more life out of it. My humidifier has rectangular wicks mounted at an angle, and only the top back tends to get a lot of minerals. I can thus turn them around and over in 4 different orientation.

Plus I have very soft water, so all combined I can get through an entire winter with just one set of wicks.

Still, I wish they made washable wicks out of fabric instead, so you could just put it in a bath of vinegar or citric acid for a few hours and then put them in the washing machine. In theory I see no reason they couldn't last for years.

These wicks are like tough paper. Yes, flipping the wick doubles the lifespan here. Also before it gets too bad, rinsing the wick dislodges the mineral deposits and slows down the buildup.

If I had to guess, I'd say it's probably the cover, not the cushion.
