Time to break out the carbide burr...

A lot of times you can tap it in a loosening direction (for an extractor it'd be clockwise) with a center punch. You'll fuck up your punch tip, but it can be re-sharpened...

>>2517751
I used this sort of extractor that you hammer in, not one you screw in
I'm fucked so I have to replace to part

Buy butcher block and standing desk legs. You can have a really nice desk screwed together in less than an hour. Its a little expensive but very sturdy and cheaper than just buying it.

Power supplies are not the place to start learning about electronics. I've been doing electronic repair semi-professionally for a decade and I still avoid opening one of those fucking things if I can avoid it. The PFC system in virtually every PSU made after 2010 makes it extremely difficult to know if the system is properly discharged, and one wrong move can easily kill you (not the meme fork in 120/240v outlet type of kill you, the several kilovolts type of kill you)

OP as this anon said >>2517691 , I wouldn't go for PSUs as my first repair, but if u have the guts and the brains why not...
so here are the 3 golden roles of PSU repair:

1. never under any circumstance work on it live or connected to the power cable!!! keep the board outside the unit completely unconnected to anything while working on it!!

2. always double check the safety off the board, especially if recently powered or if it is connected to high value capacitors that operate at moderate to high voltage (100v-2kv+), these can pack a strong punch sometimes enough to vaporize a man!!
https://www.youtube.com/watch?v=coW1RHUsf_I

so make sure they are discharged b4 u even think of working on the board!!

3.look at the board carefully, give the board a smell check and if u notice a burned smell or see a component that looks charred or cracked or burned or blown then replace it.
check for common culprits, like switching transistors and diodes, tantalum caps, electrolytic caps, thyristors, Opto-isolators and the such like since they tend to fail first and be the most stressed in operation (here i assume yk how to test them).

once u did that u can start actually repairing and diagnosing the board, i prefer to look at the mains side first, since it tends to be the simplest to diagnose, check the x and y class caps, movs and ptcs, working ur way down stream...
I am the OP from the fixinga thread, i really love seeing anons trying to fix instead of endlessly consuming, just follow the golden roles and don't kill ursellf!!!

Any simple techniques for transferring a complex curve of an object to a drawing without a contour gauge? I'm going to buy one anyway but just curious.

>>2517652
I just use a piece of thin cardboard and make a series of parallel cuts up one edge. Then as you place it into position around the curve you bend the cardboard strips up. It accomplishes the same thing as the gadget in your pic related, but it has less detail.

I'm making raised beds, 3'x3'x18". I'm using 1 1/2 inch thick wood I sourced from scrap runs. Some of it has cool patterns painted on it, some has plain white paint, some are just weathered. Wife loves how the first one looks.

I'll post a better pic.. picrel is just some shabby chic shit, but it's close enough for now.

My question is - can I leave the paint on? One has what i think is old powdered spar urethane on. Another just has white paint slathered on.

I was going to check and confirm its not lead paint, and I'm going to sand the top layer of urethane off, just because it sketches me out a bit.

Does it really matter? Is the paint bad? Can I repaint them? I'd like to protect the wood a bit, but also don't want to put any toxic shit into my wife's organic as fuck garden beds.

Whatever you do, do not use Google or any other search engine. The internet hates physical books and will lie to you so that you mess it up.

Have you tried grinding it?

Could be Monel or Inconel, both are heavier than ferrous and stainless steel and have a characteristic dull grayish color from the nickel content.
They generally don't get brittle like that, but there's all kinds of alloys with specific qualities.

It's probably veneer due to mass production limitations and the veneer rounding around the corner without grain change

On high end furniture, they'll either go through cords of wood to find matching grain or use the same piece for something the effect you're convinced you're seeing
Even in high end veneer furniture, they'll do "grain matching" which is super wasteful but looks unbelievable

I work at a furniture maker where they do folding. It's veneered particle board pannels, after varnishing they machine V channels at just the right depth and fold them.

>>2517294
>How
Start with long, wide plank
Cut pieces for box sides such that grain winds up being being only about a blade's-width or two off
Assemble
If you don't believe me, take photos of the faces and lay them next to one another and pull them slowly apart until your eye "snaps" that the grain lines are continuous across the empty gap
Achieving that *snap* in the piece is the point

They even do curves I've never seen it done in person so I dont know the specifics. They only seem to do it along the grain but I dont know if it's a requirement.

>>2517294

Check e-steps, I was getting that after I upgraded to a different extruder without changing e-steps. But I was also getting really weak prints with obvious underextrusion in other parts, so if you don't see that it may be something else.

Anyone have a huge printer? Looking at either the Kobra Max from Anycubic or that one massive Creality one.

>>2517680
I have a CR10s that I use, but frankly I've been looking at a 100mm cube printer for a while. Most of the thing I print are low, close to the bed, and fit within that volume. Plastic is just not the material for large items.

>>2517486
Modern slicers will just make some walls thicker or thinner, a 0.4mm nozzle can in theory do 0.2 to 0.8mm lines

It's still best practice to design for multiples of the nozzle size, since it will be the most accurate that way, but not a big deal.

>>2517647
>>2517641
Printing with a wider nozzle will also create stronger prints. Prints are basically layers of plastic string lightly molten together, they delaminate relatively easily. A wider nozzle means the "string" the print is made from is wider, which is more rigid (because you need less layers).

>>2517722
Yes.

>>2517647
I print with a 0.5mm nozzle. It's a good compromise between 0.4 and 0.6.

>>2517623
is the difference significant? also this is only in one plane, are your prints failing? failing by the small increase in strength? there are many other ways to affect strength geometry material, heat. yeah all things considered .6 is stronger than .4 but that's not a real reason to run out and buy .8 nozzles.

no

You can get holders for 2 cells in some sizes, like 2032 20 mm diameter

not all PVC is the same and require different glues depending on the application. electrical PVC and CPVC have differences that require glue for each type. just deal with it. you can buy the very small cans for small projects they arent that expensive. if you only use a tiny bit then you have some in case another project comes up. just be sure to put that cap on tight or that shit will dry out over the years.

You are right on the sgm42609(search on this name for datasheet) being a motor driver but the other chip seems to be some chinkshit

>>2517091
In my experience, those ridiculously labeled, shitty ICs are usually spun in-house or contracted privately, and their labels are entirely meaningless to the outside world. Your best bet is to try to reverse engineer it or find somebody else who has done that. You could also try to dump the ROM if it has any.

>>2517096
>>2517104
Yeah, it's come cheep chinkshit I found a long time ago, unfortunately after looking I don't think anyone has come across this and reversed engineered it.

I need an alternative then, but I'm not experienced in electronics. I thought trying a A4988 driver, but it has very high current for this small hobby stepper motor hmmmmmmmmmm

So long as the new parts are replacing those which are designed to ve replaced (ball/acme screws, bearings, etc) or something beyond repair, so long as the replacement is made of the same material and look/function identically, I don't really see the issue. I'd much rather see someone breathe new life into a 60 year old vise/saw/whatever than to let it rot away on the shelf and buy a plastic one from Walmart that'll end up in a landfill after 6 months.

Preservation of the past is not best achieved through meticulously keeping those the artifacts of the past in a static, unchanging state. History isn't something relegated to the distant past. History is happening as you read this, and you are part of it. The way I see it, there's infinitely more value in a tool passed down 3 generations that's been entirely replaced by new parts than there is in one that remained completely unchanged (and unused) for all that time.

Obviously, there are limits to this. If nothing is captured statically, then how will future generations know what the past looked like? Two answers: for one, there are things that need to be kept static. Important documents and art, for example. Those things belong in museums (on display). Your grandpa's jigsaw from the late 60s is not one of those things. If you choose not to maintain it and use it, through whatever means necessary, it will be forgotten. It becomes waste. Additionally, if you keep using artifacts of the past in the present, there's never much question as to what the past looked like, since one can look down at the tool in their hand and see the answer for themselves.

Study proven smol vehicle boilers then copy success. That's quite easy to do so why have you not already learnt how to make water tube (safest variety) boilers?

Read up on construction and how to properly weld the boiler tubes and shell. You can have the parts laser or water jet cut by a specialist as most machine shops do.

Of COURSE you knew about the Roper velocipede and the Stanley Steamer automobile from your exhaustive reading.

Of COURSE you visit live steam forums to ask the experts Yada Yada

yes i did have been a good boy and been doing my reading. u think 4chan would be my go to place for engineering??? also not wanting to make your traditional boiler with flu tubes, i was thinking of making it a mono tube boiler. Any way you speak of the fuel rod and lead pants??? is this what u had in mind??

>>2517626
https://www.youtube.com/watch?v=7yw3AvSheEE

mono tube boiler (information for the smooth brains)

>>2517628
Monotube is easier since no welding and for smol engines should be sufficient. If it isn't it's easy to make another stage.

Make the outer jacket such that you can remove it easily so you can pressure wash the coils. Ditto if you do a conventional water tube boiler but so long as you use a water tube version any leaks will at most smother your fire.

The easier your unit is to clean the less hassle it will be to maintain. If youre gonna do it ya may as well make it maintenance friendly,

>>2517575
Sounds like you could build an iron rack-- question is do you have a rack for your racks?

>>2517605
I have. A few pieces of 2x4 on the concrete and a couple of milk crates I have the rest of my iron and stainless on. I think I'll just buy a couple of cheap stamped steel tractor seats and make a few stools.

I actually use them on the fucking stucco exterior of my house and they’re not bad assuming I get them on a somewhat flat part and don’t put too much weight on a single hook.

>>2516898
>I’m going for a nice chill nature vibe
The only thing I can see that goes with that vibe is the one single plant you have in the room.

>>2516898
Definitely move the rug(s?) out from under the couch so it's more centered in the room, and if its really two rugs as it appears, lose one, thats not a thing.
End tables next to the credenza make no practical sense and clutter up that area.
The lounge part of the couch jutting out into the window area isn't ideal, I'd consider moving it to the near end, the coffee table is already there so it's not like it's impeding traffic flow, and then it makes a seat for someone facing the camera position. That also makes the outlet on that far wall more useful and creates the feel of a dedicated seating/conversation area, especially with a well placed rug.
Personally I would then move the tree to that side where it won't look crowded into a tiny corner and will help distract from the AC.
Put a floor lamp (torcheire) where the tree is now and it will help balance things out visually and add some drama/ interest at night when it will cast shadows from the tree into the corner that will look cool and further camouflage the AC.

It has zero internal nonvolatile memory. The Pi Picos and other dev-boards just come with SPI flash ICs. Same for ESP32s and such. See:

>change variables on my ESP8266 via http requests but the values dont seem to change

You can execute any code you like via an http request, so simplify your question by showing us the code that runs via the http request.

My esp is at 10.0.0.205, so when i enter this in a browser:

10.0.0.205/abc

and the code says :

server.on("/abc", do_abc);

that will call the function abc() and do whatever I want.

>>2517705
>that will call the function abc

that should say do_abc() to match the server.on function
