/diy/ - Do It Yourself

Benis.

>>2654570
Anything high voltage desu.

>>2654603
well somebody's gotta do it

>he doesn't DIY surgery

>>2654570
>never DIY

>>2654570
>surgery
Depends on what you mean by that
Stitching a bleeding wound with tailors kit or cutting off/cauterizing moles is somewhat of a surgery
Pushing/pulling joints in place etc
I would never diy altitudes/depths related stuff like manned subs, manned planes, parachutes, anything manned and going beyond 2 stories high/deep

>>2654603
What's annoying is that OSHA considers 600V and higher, "High Voltage" but other agencies consider anything over 50V AC high voltage

>>2654747
DIY aircraft used to be the only way to fly, you just lack courage.

>>2654570
anything hazardous that you don't understand competently enough to hold your own against the existing experts or professionals in the field

>>2654750
>What's annoying is that OSHA considers 600V and higher, "High Voltage" but other agencies consider anything over 50V AC high voltage
The NEC only concerns itself with anything over 50 V. That's why PoE at 48 V doesn't matter.

>>2654750
NEC and such have lower standard for 'high voltage' because their main concern is risk of fire to the structure in which the circuit is installed. OSHA is more concerned with worker safety, and sets their limit at 600 because that is generally viewed as a the lower bound of where arc flash becomes a major concern as opposed to electrocution.

I don't fuck with plumbed fuel. I have the skills and confidence to do plumbing. I understand that it's the same kinds of principles on paper but it's not worth the risk

>>2654751
DIY the plane, don't DIY the design. Simple shit, you can get anything from picrel to a open-seat glider.

Right? It seems to be the perfect airplane.

>>2654714
came here to post this
don't use an xbox controller

>>2654570
SCUBA stuff and especially closed-system rebreathers.

Used fuel tank welding/cutting/brazing repairs.

Safety gear for dynamic loads like fall arresters and harnesses.

High-voltage capacitor banks with ridiculous total capacity.

Organic-mercury substances and application thereof.

Honorary mention: visible and especially IR lasers 50mW and above without proper eye protection. Like, certified, approprate optical grade and for specific wavelength.

I called a guy to do my garage door spring because I was afraid of losing an eye.

I called a guy for my AC compressor because I was afraid of getting fucked into the dirt by the long dick of the law.

>>2655216
Was working at a car repair shop when I was 17 and one of the garage door springs snapped, sounded like a fucking shotgun and I didn't know what had even made the sound till the next day.
The 4 mechanics decided to hire somebody else to repair it.

So yeah, I'll never mess with that.

>>2654977
Why not? Their choice of controller didn't cause the failure. As long as you have another way to control the thing it's probably the best option.

>>2654714
That Danish guys DIY sub was pretty cool. I wonder what ever happened to him, seemed like a nice young man, no doubt finishing his rocketship

>>2655246
You'd probably want something fire safe desu

>>2655260
I think he quit. He had a lot of crazy female fans really losing their head over him and shit. Couldn't deal with the pressure. Danish are weird.

You're non-american I hope/assume? It's not illegal to install, service, or fix your own HVAC in America.

>>2655337
It isn't, but venting the refrigerant is and there are legit bounties offered for anyone who can be proven to have vented off refrigerant. You can diy it without breaking any laws but I still wouldn't. To easy to fuck up to the tune of "costs more than getting a professional" and that's not even factoring tools.

>>2655351
>venting the refrigerant is and there are legit bounties offered for anyone who can be proven to have vented off refrigerant
Yeah I'm sure there's someone sitting in a fake pizza van outside your house counting the milliseconds you're venting refrigerant piping new lines.

I challenge you to find the last time the EPA fined someone for illegal refrigerant venting. Hint: In the last ~30 years they've fined an individual once, and that was for intentionally puncturing an industrial size refrigeration system for an entire factory.

fpbp

Very near if not at the top of the list for worst case scenarios if your diy efforts fail is anything having to do with making fireworks/explosives or rocket fuels.

To be truly capable of doing so "safely" (to the degree that it is even possible) you need a level of expertise that would qualify you as a professional.

>>2655353

"High voltage" is like 100kV, everything else is medium or low voltage.
10kV is basically the same as 100V except more stuff is conductive. Just dont fucking touch it, broham.

>>2654999
>Organic-mercury substances and application thereof.
above all else, THIS.

>>2654570
I'm going to say tree work when the tree threatens something you don't want smashed. I won't fight someone chopping down trees in the middle of nowhere but when it's right over your house and you either need it to fall in the exact right way or need it to come down in peices then it's best to just let the guys with insurance do it. Also not having to deal with the leftovers is worth a lot of money when your time isn't worthless.

>surgery
i had to perform two small cuts on myself for some minor shit and both times were flawless. apply a cold pack until you get frostbite.
perform the cut, you will hardly feel a thing and not bleed. and in my two cases i just put a paper towel on it and let it heal itself, no need to stitch.
i dont even know how i got the idea with the self applied frostbite myself but i can confirm it works. the frostbite leaves no marks so nothing to worry about unless you grossly overdo it. but that should be difficult with a dinky cold pack

>>2654750
>OSHA considers 600V and higher, "High Voltage"
What a weird system. Where I'm from anything under 1kV is low voltage, 1-35 kV is medium voltage, 35-330 kV is high voltage and above that it's extra high voltage

>>2654570

Psyop.

I'll never fuck with garage door springs. There's like a dozen garage door companies in my town all competing for business so having a tech come out for a service call is dirt cheap. Only had one snap before. I thought someone had rammed my garage trying to break in so I grabbed my AR and was in full LET'S FUCKIGG GOOOO mode only to find a rusted, snapped spring.

>>2656320
if it left no marks then it wasn't frostbite, also a cut that doesn't need stitches doesn't count as "surgery"

>>2655610
I know somebody that almost lost a kidney, he was using a pole saw and a limb swung weird and stabbed him in the gut.
Multiple broken ribs, bruised liver, and if it had been about 2 inches further it'd tear up his right kidney.

>>2655353
Scrapyards snitch and get the bounty when somebody comes in with a refrigerator or AC that has been attacked with bolt cutters.
It's serious shit now dude, they're not playing around when it's basically free money for a quick phone call and a few pictures.

>>2656445
you have no way of proving it wasn't empty already
refrigerant leaks on its own
which is why only one bounty was successfully claimed (as in snitching lead to a conviction and thus the snitch got the bounty)

>>2656445
Great, show me the EPA payout. You can't, because it didn't happen and you're spreading old wives tales of 'a friend of a guy I know got caught'.

>>2656445
ac evap coils are one of the more profitable types of items to scrap. The scrapyard absolutely doesn't give a shit about this.

Bronze headstone markers or railroad rail? Yeah, they might snitch on those

>>2655582

>>2656952
what counts as pay-able proof? video recordings?
I scrap and wont leak the shit out for profit, but when the city dump rejects 2/3 of my dumprun for environmental purposes, and wants me to pay per item ($40 for a mini fridge, $30/tire, etc) then i just sawzawl shit and put it in the garbage can

>>2654570
blow job

>>2654570
reckon you could diy many surgeries if you could actually get the proper tools

>>2654815
50V is a threshold because that's when it can pass through your body.

>>2654570
Surgery

what about veterinary surgery on stray animals that develop problems

>>2655280
>Couldn't deal with the pressure.
doesn't he have the sub for that

>>2655940
Yeah, I've heard of them. You could DIY the design, but you'd need to how a lot of knowledge. Have months of your time and a solid grasp of every system involved? Knock yourself out. Much easier now with CAD and simulation software, but you're still better off getting your napkin drawing checked over by an actual engineer.
>>2655280

how is this a diy design

>>2657875
It's the most convenient. Same reason as most rooms having four walls and not being circular/ hexagonal/ whatever. Yeah you'll see some but most just stick to the plan.
>picrel is a french WWI fighter

>>2657891
you can never truly do it yourself as far as ideas

>>2654750
its simple, 600v is what one would encounter inside a building, everything thats higher is generally power distribution and a whole different field
>50V AC
thats where ac voltage becomes potentially dangerous, that level exists so untrained monkey can fuck with control logic

>>2657914
It's simple, the limit isn't there to protect you the employee from dieing.
Any electrical that has significantly more than 100v rms potential to ground will usually just kill you like the risk exponentially increases from near 0% at that point.
480v is common in the US and each leg is 277v to ground or ~200v rms. You just die in most cases touching that

Jerk myself until ejaculatory spasming

>>2657904
You're essentially limited by what can reasonably be flown. Computer aides helped make some crazy shit like the B-2, but at the end of the day you need more lift that your net weight, and you need your plane controllable.

You got any ideas, anon? I am trying to design one, don't really have the cash to build anything though.

>>2657944
it is not about dying, it is about being certified to work on gear xyz.

The UC3 Nautilus has since been destroyed after Peter Madsen was found guilty for the murder of Kim Wall aboard the submarine. Peter Madsen is currently serving a life term in prison.
https://en.wikipedia.org/wiki/UC3_Nautilus
The next biggest privately build submarine is the Euronaut, which is much more sophisticated in my opinion, including a lockout dive chamber for excursions outside of the submarine while at depth.

>>2655741
i descaled my own teeth after a long time of being poor and having buildup and nothing bad happened at all and my gums noticeably healed.
enamel is much harder than steel, and the difference between calculus and enamel is as plain to feel as the difference between running a butter knife over marble and running it over toast.
the only "downside" i'd say is it probably takes a dentist like 20 minutes but it took me multiple hour long sessions being very careful.

>>2658074
That's kind of a shame to scrap it, I guess there's no buyers for a murder boat though

>>2658307
They wouldn't let anyone buy it, they destroyed it intentionally.

>NNNNOOOOOOOO YOU CANT DESTROY THE MURDER SUBMARINE!!! THE HECKING ENVIRONMENT ISNT REAL

>>2655351
Those who have done it disagree. Why do you permit yourself an uninformed opinion?

The first time I did an AC on a truck it was because the "pro" missed a leak. I've since completely replaced three of my trucks AC and helped my bro do two after which he bought his own gear and also installed his own mini-spit without complications.

It's plumbing, pumps, orifices (not yer mums) and heat exchangers. My home HVACbro showed me how he replaces pump, contactor and dryer when he did my heat pump and I'll do any in future myself.

>>2656445
Citation fucking needed. Examples fucking needed.
I've been scrapping since the late 1970s when car junk yards relied on cutting torches.

>>2656565
Rail is commonly scrapped but not worth it. Sources can be proven if wise scrappers get bills of sale so I do.

Headstone markers are high vis so I'd expect them to call the cops.

It's not that scary, just don't fuck up.

Anything that requires expensive and extensive testing plus quality control
>safety equipment like hardhats and fall protection
>high pressure vessels
>medication manufacture (not counting processes that are easy and have been tested by others)
>high precision sensors and instruments
So basically anything that seems ten times more expensive than what it costs to diy
