Costume!

Always remember, it doesn't have to be the theme, post your work, post what you want to talk about as long as it has something to do with sewing in general, or the craft in general. We welcome everyone and will try our best to help you out. Yes, sewing is an art, it's a practicing art, you will always suck at it, but remember that everyone starts somewhere, so Google everything!

Or just show off your work.

BTW this thread has been going strong sense last Halloween and we're about to hit Halloween again! Neat!

Your question may be stupid, but ask it anyway.

Got a few more sanding passes to do then its time for the osmo and ceramic coat

Why are battery main switches made of steel and not copper or brass? In this picture, those are just washers, not contact pads. You're supposed to screw your cable terminal between the two nuts, so the bolt itself is the conductor.

What type of engineering degree do I need to be able to put together this chair? I spent hours on it and the digarms show the same screws with a check mark or x to use or not use. Whats up with that?

Chainsaw thread. What chainsaws are you guys using and what things you like or dislike about them? Would you pick a different saw if you would be buying one today? Also do you fix and maintain them yourself or use shop?

I built this DIY antenna out of an old coax cable. I used some garden snips to cut off one end and strip off the shielding (I don't recommend you do this, it's tedious as fuck and you gotta be extremely careful not to cut off the copper bits) and arranged the copper into a dipole.

I can only get 1 channel with this antenna, as this thing can only pick up stuff VHF transmissions that are really strong. I've tried repositioning the copper elements to better receive signals to no avail. This pic is my third version, the copper is bent to try and make it a bowtie.

I'll buy an antenna on Amazon, but I would still love advice on how to improve this antenna I made, namely increasing it's effectiveness and picking up UHF signals. I can only do suggestions that can be done easily at home, no power tools, additional devices to buy, etc. Preferably something with aluminum foil and cardboard.

Absolutely NOT a "tech guy". 45y/o tradeworker, left off at DOS & Qbasic in '93. Found some 2016 tech during eviction remodel: 2016 Galaxy Tab-A and 2016 HP Stream 11. Do not be fooled; all the "tekkie lingo", specs and processes I will be citing are new to me, learned over the course of these projects. I knew absolutely fuck-all about it before I started.

SM-T580 tablet has 2gb ram. when found, it was running Android Oreo. slow as shit and no storage space for anything. I could surf the web and shitpost on Chan, but had no space for memes, Pepes and/or videos. did lots of research and relied on Grok for a fair amount of process. that said, NOTHING was easy aboot this... for me. I found the tablet and craptop last December. tablet has been in a bedside table since it had
no storage and was too slow to be of practical use. I will try to outline the entire 2 day ordeal (15 fucking hours) as succinct and condensed as possible.

I found a 32GB micro SDHC card while tearing oot the carpet & padding in a remodel. my first thought was "COOL! I can double the eMMC storage on my Linux Stream Craptop!" however, after a quick discussion with Grok, I decided my first use of it would be to flash a new OS onto the Samsung Tablet. did a little research into available OS options and learned aboot the basic hardware/software that operates little phones, tablets, etc. quite different from "regular" computers, it turns oot. Decided on "LineageOS" for what is essentially a clone of Android 13 but with full current patch and security support. I found the Lineage file on some website, perhaps Github, unsure exactly where. I was also told that I needed to I stall "MindTheGapps" to access Google app store and run anything other than basic web browser on it. I started my questionable journey at 8:00 Saturday morning. I wrote the aforementioned files onto SD then connected tablet to craptop via USB data cable, which I used to install something called TWRP by "TeamWin".

Scrappy here again and I have found a gold mine, but with a hitch. Behind an electrical contractor's building there are some dumpsters that always contain beer cans and copper wires. Copper wires can get good money, especially the bare ones. But there is a homeless male living in a tent here and he says that all of it is his and he threatened to cut me. I told one of the electricians and he said that the cops won't do anything. This situation is intolerable because the dumpsters are often full when the hauler arrives, so the bum actually collects nothing. What can I throw into his tent to neutralize him while I collect?

How much can I sell this for? It's closed link solid sterling and weighs 41 grams.
>No, $60 is not an acceptable answer.

Hello, I saw another watch thread here people were responding to so hopefully this question isn't too retarded. Pic related is my grandfather's old watch. It runs fine, but the second hand doesn't turn. I think it has to do with this copper wire you can see in the upper part of the mechanism. Anyone know what that's for/what it might be replacing? Potential fix? I know nothing about watch mechanics but I have a good amount of small general tools and my day job is electronics repair so I'm not bad with my hands.

and it didn't cost me no 50 bucks as le kuhnepix.

use DigiKey's or Octopart's parametric part search. Then purchase from one of the sellers listed above.

>how do I get started with microcontrollers, where should I start?
There is no defined starting point, grab a book and start reading or buy an arduino off ebay/amazon and start messing around. There are a plethora of examples online to get started.

Background (can skip): My door has developed an issue on rubbing against the frame, which is especially becoming problematic as the force required to open it is starting to pop the handle out of its socket. I recently discovered what typically creates this fault is misaligned hinges creating a larger gap at the top of the door frame (between the hinges) compared to the bottom, and upon examing this door, that seemed to be the case. So I have to remove the hinge and then realign the hinges, however:

Problem: I can't for the life of me get this pin out the hinge. I initially tried to tap it out using a punch and hammer from the bottom up, however after closer inspection, and getting nowhere, it seems like the pin may have been inserted upside-down, as the bottom of the pin appears to be wider than the top. I then tried tapping it out the other way, but also nothing. I've also tried spraying it down with half a bottle of WD-40 to try loosen things up, as well as using pliers; also nothing.

Any ideas? Will I just have the take the hinges off completely and get it out that way?

hon, good news... the toilet seat will always stay down now. I gotchu babe.

Wally World is doing their summer end clearance on outdoor stuff, go stock up now for next spring/summer bros

Also got a stack of mower blades that fit my mower for $3 apiece

has anyone tried this before, also cardboard chairs/couches?

It doesnt need to hold much besides a speaker and my tablet maybe. Just thinking it wouldn't be that hard to build and cost less than $20

The downside is the fire that burned on the area, seems to be mostly smoke damage and since walls are bloke/brick with rendering it could just be pressure washed and call it good, maybe apply a new layer of rendering. What do you guys recon? I've been on a lookout for a property for a while now and had a thread going before but nothing came to through so far.

How do I get the top lights on?

Please help it looks retarded without the top lights on

I am at my wits end. I have a GE GTW460ASJ washing machine that will not stop failing a wash cycle due to an imbalanced load
I replaced the suspension rods, I made sure its level, I took it apart and inspected all components, belts, pump, vacuum line, etc.
I ran the diag, only shows unbalanced load error. everything else seems to be working.
It does not have a balance weight, but it will always go out of balance and end the wash cycle. I cant wash more than a few items of laundry at a time. Even if I place all the items in carefully and manually spin the drum to ensure its not wobbling, it will still go out of balance during the wash.
It usually ends up wrangling and knotting my cloths during the wash creating lobs of wet balled up clothing that causes it to go out of balance.
I have reviewed all available parts on this washer and dont see anything else that could be replaced or serviced.
What else could this be?

Is there any non or minimally invasive way to repair a inguinal hernia at home? have one that's been gradually getting worse over time. I have no medical training but I've pulled my own teeth before, removed one of my tonsils, and stitched up a bad laceration on my arm before,

Just got these two 63cc 800w generators for 20 euros. They both run well and deliver their rated power but the problem is that they only generate dirty power, only good for lights and basic power tools like drills.
How do I get clean power from them so I can plug in my fridge and charge electronics without frying them during a power outage?

/diy/ I'm in such a shit position at the moment. I've got a house that I've let the front and back get absolutely overrun with Russian Thistle (tumbleweeds)

Season is long over so not much I can do now.... But now I'm in a lovely predicament on how to get rid of this shit. I don't wanna keep spending money on it. I figure I can just pull a few a week crush them up and put them in a bin, since I don't really wanna just tackle a giant dumpster or something. But that still sucks. I don't care if my yard looks like shit for a while.

>My mower can't get over them
>Going through with a carbide blade isn't doing shit
>Don't wanna start a fire near my house
>Last quote I got to deal with the yard was like $1500 which is absurd

Any suggestions on what to do here? I figure I can just spend the next six months pulling them but that does suck

I recently moved to an apartment that's second floor street side, and the amount of dust I get is insane. I have to vacuum every day, sometimes twice a day.
I heard about Corsi Rosenthal boxes as DIY air purifiers and figured I'd give them a try since I think a conventional air purifier with my budget wouldn't do much, but I've encountered two roadblocks.
1. Box fans seem to be virtually non-existent in Europe. I've only found a 30cm desk one, though the guides online seem to recommend at least 50cm wide ones. Instead we got those circular ones, though I guess I could use cardboard to make a square frame for it.
2. Merv 13 filters which were recommended seem to also be an US thing, getting them in Europe costs me twice as much. I've read that HEPA filters don't work as well because of airflow pressure stuff that I'm too dumb to understand, so I don't know if there's an european Merv 13 equivalent.

So my question is, are there any europeans here who made CR boxes? And if so, what did you use, and did you manage to stay in a $200 budget?

So I just found out you can get infinite amount of raw unprocessed sheep wool for free. Apparently all the value is in the processing, the wool itself is a nuisance.

What can be done with it? Feels like insulating a house would be a great way to use it but there must be some catch right?

Built a greenhouse in my yard. Ask me anything.

If I wanted to scale these up and make a pair that was able to cut 3-5" diameter pieces of hardwood what would be the limiting factors besides leverage? If I could just lop my firewood instead of having to use a saw I would save a good amount of money

dumb question from a dumb anon; how do i attach brass to leather sheaths? glue? studs?

So, together with a friend, we have decided to make our own console for fun and giggles. This surely is an undertaking but this is an idea we were considering for a long time and as we got more and more experienced with circuits, embedded programming, 3d printing and stuff like that, I feel like it would be finally in our reach.

I never really looked at other people's similar projects, I have no idea what I'm doing honestly, but I can write code and I can use google so I think we will figure it out and get there eventually.

I will post our progress in this thread.

Do you use multitools in your DIY projects as main tools or is it standard tools for you? Personally, I use pic related as my main when I do woodworking. Haven't touched pliers, drivers, knives or saws since I picked it up.

I am designing a house, based off a kithome

My girlfriend says she wants to have a lot of kids, so three smaller bedrooms would essentially be boys, girls, toddlers

The concept is that the less used rooms like bathrooms are on the street side of the house, and the house is as far front of the property as possible. This gives a larger backyard with the living room and all bedrooms having glass sliding doors that open directly onto the rear deck into the garden.

not sure about that toilet on the left. Bathrooms all have double showers because it's really a cheap thing to do, and allows efficiency in the morning

I think the Rumpus would be kind of a computer room for kids to have their games consoles and computers in a space that's still public, but not going to spread noise to the whole house

I so I made something with wood (fake fireplace for electric insert) and painted it but it looks VERY blotchy. Its a mixture of 2x4 lumber and some thin beach wood sheets. I am using black semi-gloss which I now think is a mistake and I should have used flat black since the surface was only very lightly sanded.

is there a paint for wood that works best to cover all the imperfections? I shocked the sheets looks so bad because they are smooth, but it is as if they were treated with something chemically. The crown molding i used looks great of course, smooth prepped surface already.

Also this is a latex paint. Valsar

What are some good/cheap solutions to build my own cheap cold plunge? I have an ice machine and access to a lot of ice, I just don't know what kind of tub would be the cheapest to get the job done. What do you guys suggest to use as a tub?

should I buy a chinese excavator ?
they are so cheap

its like a smithco bandit. they turn in the middle of their body and have Hydraulic dump. they are like golf carts but way stronger.
i would love to have a pug at my house.

Alright I've been having a hell of a time trying to find a simple design for a post based wood crane. It's not going to be handling heavy loads, it's to help lift me groceries up my rather steep porch cause I'm lazy. I had some work done and had the gents attach a post. Now I've salvaged the painted post to the right of it for potential reuse. I plan on getting a cheap winch and then mounting it either on the unpainted post or the painted which I plan to make the boom. I had planned on using a swivel base, but I was rethinking and they don't do well with the sheer that the design would cause. So do any of you old bones know if what I can use to do this? I'm not deadset on using the painted post.

Note that the base is only bolted to the rail so this crane cannot accommodate much of a load and it isn't going to be used for that. The winch will be hand powered
