Okay retard. What temperature are you experiencing right now? Are you satisfied with your temperature? That’s what I thought. Pussy.

modern ameriFATs are too fat to live in 75% of their country's climate zones
>heat
lmao boomers heat a whole 3000 sqft house while using 1 room 99% of the time
>AC
ditto, gotta keep all 3000 sqft at 70F 35%RH all spring/summer, while only using 1 room during the day and 1 room at night LMAO

they don't do any physical labor whatsoever (no need to cool off after working), they don't exercise (no need to cool off after exercising) and they don't go outside ever (no need to warm up or cool off after being outside) so those excuses for indoor climate-control don't fly

2 only fans to watch your mom getting pounded in 2 holes.

>>2793664
Yeah if you live in the top 1% of the world f pool r weather.
I do and my setup is 6x 120mm server fans in a line under a window.
A electronic thermostat allows me to set the temp and restart thresholds, and a buck converter lets me drop the voltage for less noise when it's cooler.
11.5 months of the year it is under my target temperature of 16c by sundown, so the fans just pressurize the room and force in cool air. Dust has never been an issue, it literally doesn't exist here

Hello police, this is an emegency! there's a black man outside my house and i think hes trying to break in. yes, it looks like he has some kind of weapon in his hand. I'm scared

Why do people lose their composure like this? Maybe it’s just one guy but there’s a theme of people on this board being outraged by any mention of HVAC workers. You got scammed, you’re a bitch, get over it. Being so transparently pissy is a dead giveaway that you got conned by some knuckle dragging tradie

>>2793664
I'd be interested in learning about DIY HVAC but can't find the right resources. My use case is for keeping a 8m2 house ventilated. There is no electricity there, so I'd need a system that could be passive until I can get solar power there.

>>2794807
>a 8m2 house
Nigga, that's called a shed.
>passive
open some windows

>>2794816
The shed has a small window and the door nor the window can remain opened while I'm gone. If I can learn to duct a simple passive system, I can ensure the place always has quality air. Moreover, I've been thinking about
using the duct as a Canadian/Provençal well.

The feeling when old people arguing.
>>2794807
Thermaltake brushless 200mm fan $14
Small solar panel $20
Converter from solar voltage to 13.8v (or 12) $10. (may not be needed - see below)

that's it, and wire.

The fan takes extremely little power. Even a 25w panel they sell all over TEMU will do. The flex ones that have 6 cells and a 12v dongle coming out of a black box on the back, have an internal regulator that knows how to charge a 12v lead acid. I've been doing that straight, mounted on a tractor hood w magnets, for years. You do not need the bullshit charge controller they offer to bundle with it. They just have no idea what they are selling.

It also comes with the barrel connectors and cables/wire, so you can skip the buying wire part too. Just that panel and the thermaltake fan. The fan comes in black, or clear with blue LEDs. Get the clear and delete the LED's. They just pop out of the socket.

Where TF does a Japanon Buy Chemicals?

How do I buy chemicals? I'm in Japan but these idiots are so uptight about everything it's damn near impossible. I've gotten most solvents I could reasonably need (barring tuolene) but nitric, hydrochloric, and sulfuric acid are all just straight up fucking banned. Best you can get without a permit is 10% of HCl/H2SO4 and 5% nitric acid. Like, it's insane. Yeah I could buy TEN LITERS and fractionally distill over a month (and probably kill myself in the process because retard fingers and earthquakes) but it would cost a stupid amount and take forever.

What companies ship to JP?? Even fucking chemsavers won't ship int, and most eurofag suppliers won't ship to JP.

What's worse is that even when they do ship, customs is basically guaranteed to fuck me over. The only places I've found domestic that sell anything at all are Matsuba on Amazon and Jikken-kun (hayashi chemical corp on monotaro won't sell to individuals). WTF do I do?

I really wanna get my hands on some thiourea but I can't find anyone who sells it.

Guess you have no choice but to make your own nitric acid from simpler to find ingredients.

>>2793680
Toluene is banned in california. I bought some toluene a decade or so ago, and never used it it’s slowly evaporating.

So, you can go with things like drain cleaner, and some lead-acid batteries have a separate electrolyte pack you add to the battery when it’s time to use it for long term storage (sulfuric acid)
Also things like driveway etchants sometimes are muriatic acid as it’s known (hydrochloric acid).
I bought some nitric/phosphoric acid a few decades ago that was “efflorescence cleaner” — which is that white stuff that forms on bricks over time.
There’s a guy that was doing electroplating with what appeared to be drain cleaner in japan I saw not too long ago. It’s obviously got some other stuff in it, but it worked fine for the job.

It’s funny, I recently learned that samurai swords are actually banned in japan…. All this time I thought, like, everyone had one hanging over their fireplace.

Japan is strange. One of the first things you learn when you move abroad is that there is no "spectrum" on which different societies exist. Different places have different standards for different things. You can buy things here on Amazon that would result in a DEA raid in the US, but it's illegal for drain cleaner to have more than 9% H2S04. You can drink in public or private whenever and wherever you want, with extraordinary impunity, but a milligram of marijuana is "game over, do not pass go, do not collect 200". Like, I literally bought a liter of benzaldehyde and customs didn't bat an eye, but importing any quantity of *sodium hydroxide* (aka lye) is a criminal offense.

It's weird. I would've imagined that japananons, being as autistic as they are, would've had an in-group community of hobby chemists, but there's basically nothing on the internet about it. No chemistry youtubers (other than Genki lab but that's regarded), nothing on yahoo answers/chiebukuro. It's just straight up not a thing here. Or maybe it's underground and irl.

Common chemical that got banned is probably due to public knee jerk of some psyco pour anything caustic on people's face after getting fired/dumped.

>You can drink in public or private whenever and wherever you want, with extraordinary impunity, but a milligram of marijuana is "game over, do not pass go, do not collect 200".
As it should be, based.

Hey, this is 99.99% something, no?<br>This is what I was talking about—using household ingredients that most people don’t think about using that have the chemicals in them.

>>2794762
It says 99.99% nigger killed. Not 99.99% pure

Britfag here, had the same problem. I joined a bunch of chemtuber discords and eventually found a few private chemical seller from like Poland and France.

Since your a nip I'd advise looking towards China.

Also agricultural suppliers are good. So look around locally.

Either do that or hire a lawyer and build a little LLC . File the proper paperwork and you'll be good to order all the mineral acids and weird reagents you want.

>>2794917
FYI agri stores have all sorts of fun chemical.

Formaldehyde, zinc sulfate, calcium oxide, sulfuric acid. Just to name a few.

>>2794750
drinking alcohol is nigger-tier

>>2794783
Correct. It's just the standard 99.99% microbes murdered marketing. What's really weird is that I can't seem to find sulfuric acid based battery fluid. I don't think that's illegal, and I saw some fag on twitter post about it once, but I couldn't find the product itself anywhere.

Also just, distilling sulfuric acid scares the shit out of me and I'm man enough to admit that.

>>2794917
Can you drop your discord? I'd like to join those if you could. Apologies for the breach of decorum; I'm just really desperate at this point.

Smoking weed is nigger tier. Total dr00g death. Total nigger death. Fucking stockade any foreigner who does dr00gs. I like my perpetually drunk society.

>>2794957
>distilling sulfuric acid
No need to distill it, just boil the battery acid outdoors in an appropriate container until the fumes coming off of it turn white. If the acid is used, it will be contaminated with lead, but can still be useful for many reactions (like making nitric acid).

MSR claims that camping fuel, white gas, is available in Japan. This is “Naphtha” for ameriboomers, and is somewhere around toluene or xylene. Naphtha is in the process of getting banned in the land of the “free” as well.

>>2796405
Why? Too many woodfucker got their house burnt down for insurance fraud?

>>2796552
Nah, you’d think something like that.
The purported reason is it has benzine rings and is a carcinogen.
I don’t believe it because it doesn’t make sense because of the health care situation, where health care providers have huge incentives to give people cancer.

So what reactions are tickling your brains right now? For me it's wood -> artificial vanilla (lignin -> vanillin)

>>2796602
Nothing hurts us but our own choices.

Nigger nickel balls. Ambeed just hit me with the "akshually one of the thigns you ordered is halfway almost pseudo dangerous sooooooo we're charging $350 for shipping on your 85$ order now okay sweaty?"

>It’s funny, I recently learned that samurai swords are actually banned in japan…. All this time I thought, like, everyone had one hanging over their fireplace.
Kinda. Technically, blades that are made with traditional materials and methods are considered "works of art" or "cultural objects" and therefore not weapons; it's sort of like a gun being C&R eligible. Japan passed laws banning long blades in the 1950s because shin-gunto (those crappy mass produced swords made for the military in the 30s and 40s) were featuring pretty regularly in violent crime but swords as a whole were too culturally important to just do away with entirely so they left a loophole. Prices for "genuine nippon steel folded mirrion times" swords with the paperwork to prove it range from about ~$3400 USD for blades with marginal collector interest to millions of dollars for important artifacts and katana from well-known smiths (contemporary or otherwise) generally start at the price of a new car.

>>2793680
Japan is one of those places where the government reacts to notable incidents by banning shit and people tend to just accept it.

Toluene is regulated not banned. Always always always read the law if you want to obtain chemicals.

>>2794570
Is that excuse viable? What other excuse might work better?

Hair straighteners and dyes are unusual enough that might work. There is a market for anime hair color. Is there already a brand that covers a very wide range? If not you might make some money.

>>2798505
> toluene not banned
It’s illegal even to *possess* toluene in the center of the world: california.
It’s not banned because it’s carcinogenic, it’s banned because they don’t want people to store any kind of fuel. Gasoline is carcinogenic, too, but part of the metallic additives turn it into a gel when exposed to oxygen so it’s not worth storing it.
Toluene white gas, xylene, naphtha, don’t have the additives, and they don’t want you to have them.

>>2798634
If you wanna store gasoline for a long time just hit up your local small airfield and fill up some jugs with avgas. Shit lasts forever. I do it all the time for my racecar that has a highly strung out old carbed engine and needs high octane leaded fuel.

>>2793680
Make a hobby of building miniaturized chemical factories. Start with Haber process and work from there. Do it all electrically - press a button and chemicals start dripping. Have it all automated with Arduino. Use common feedstock like water and charcoal and air. Put it all on youtube with plans.

>>2798634

No, it's banned because of muh meth labs.
