Do I need to ground this power supply? I'm using it to power an audio amplifier. If I do need to ground it, can I ground it to the speaker chassis, or should I use a grounded power cable?
>>1135888
Anyone?
What the fuck is a grounded power cable? You should let somebody help you who knows what he's doing

You don't know what a power cord with three prongs is?

How do you guys usually deal with enclosures
I'm trying to build a simple power supply and am having problems finding things to put it in
I'm scared I didn't solder my heatsink to my cpu like op's pic
how screwed am I?
No woodworking thread? For shame. Or did I just overlook it? Post your shit!
Working on the top for a dining table I'm building. 3/4" Birch plywood, Poplar trim and dowels. There is a 2" wide strip of the plywood on the underside to make it appear thicker and give the trim something to stick to.

Wanted a new fight stick. Made a new one from Queensland maple, mahogany, and wenge stringing. That was about 3 months ago now, and is the most recent thing I made.
And now my friends are gonna find this post and make fun of me, but that's okay cuz /diy/ is cool.

Dayum son
fucking soldering iron gave out, i dont know what is wrong with it.
LEDs work fine, so it is receiving power.
NOTHING heats up at all. Nothing.
>Can this be fixed?
>What went wrong with it?
>>1129361
>>Can this be fixed?
Probably not without destroying the handle.
>What went wrong with it?
That style of iron is very cheap and generally only has a few parts inside of it. Something was probably put together badly, which caused that part to overheat and burn out. I bet if you opened it you'd find a broken contact somewhere inside of it.
>>1129361
Do simple soldering irons really just die out like this? Is this normal?
>>1129365
I have opened it up before. It is full of some chock material inside the visible metal piece. The rest looked fine though. I will post pics in a minute.
Tools Thread
got one of this.
are these capable of cutting steel/iron or only woods?
>>1129615
wood only. though you could probably do a really soft metal like brass or copper.
Fucking help me /diy/. I am not a regular here. I barely come here to ask questions, but i need you're help.
I live with my parents (no job lol :( ) in a small fucking apartment and i like to stay up all night, while my folks have super ears and trouble sleeping at night. This limits my nightly activities (since i also play the guitar) and my pops productivity at day. I asked about sound blocking my room but i had been told that the materials that actually sound block are expensive as fuck, and that the most cost efficient way to sound block would be to just get a bigger house.
Is there anything i can do? any cheap materials? any home materials? The walls are made out of concrete but rather a thin layer.
>>1126796
nope.
we have this question on a regular basis, and the answer is always NO unless you do some major removations.
Quit being a NEET and get a job you degenerate
How to keep neighborhood cats out of my flowerbeds and from pissing on my truck tires?
I've tried what Google suggested i.e. orange peels, coffee grounds, used dipping tobacco and they still keep coming. I can't even walk outside onto my front porch without smelling piss.
>>1126290
Buy a dog duh.
>>1126299
I don't think that'll keep cats out of my front yard lol. I'm tempted to trap and release them.

Inside city limits? Then there's probably a leash law that applies to most pets. Call animal comtrol.

I've been having some electrical issues at home.
The other day my earth leakage fuse was tripping even with all the other switches turned off.
The problem seems to have fixed itself now, but it was happening during heavy rain and so I expect the problem will come up again some time.
Is there a method I can use to test individual circuits in my house's circuit board to isolate the problem?
>>1137608
get an electrician. if you're asking this question you dont want to be playing with live wiring. its probably exposed wiring so when water gets on it, it shorts.
electricians have fancy tools like insulated screwdrivers, boots and multimeters that are expensive.
>>1137610
>electricians have fancy tools like insulated screwdrivers, boots and multimeters that are expensive.
I have all these tools and I'm not paying a loltrician ridiculous prices to tell me something I can figure out on my own.
I will take the risk, I just need to know how I can isolate the offending circuit.
seems your main power line isnt properly isolated.
get an electrician.
Totally effed up and posted this in /Out/. Was not well recieved, Lol. I guess this is the place for this discussion. Any welders on here? I'm interested in it as a hobby and have a few questions.
1) Is it fun?
2) What can you do/make with your skills?
3) How dangerous is it?
4) How dangerous is it to do drunk?
5)What the hell is mig welding?
6) Is this the proper hobby that could eventually lead to black smithing?
If Welding is too crazy and dangerous, I might just take up wood working. Even though that is pretty dangerous too. I hope I'm not too retarded to do these fun, hands on activities.
Nice try, Satan
>still doesn't know blacksmith is one word, not two
>oh yeah, this will go well
1) it can be
2) i can't really make shit, i just fix shit
3) mostly depends on the materials you're working with
4) go fuck yourself
5) metal inert gas
6) no
Does anyone know when lead stopped being used in construction? My dad was gifted a tool box filled with incredibly old nuts, bolts, and nails(some it even goes back to the 50s). He wants me to organize it but I'm not sure what I should keep and what I should throw away.
Take it to recycling
>>1137229
What are you talking about? If there IS lead in any of it, and I have no idea why there would be, wash your hands before you eat if you handle it, otherwise use it and don't worry. Jesus H. Is this a troll? If so 2/10 made me reply and I learned to not pay attention to idiotic threads involving lead.
>>1137229
lead is soft. i'd be confused if bolts were made of lead. lead roofing nails were common. just compare the mass of a suspicious nail to one of the same size that you know is iron. if its much heavier, it's lead.
Spring is right around the corner now and I'd like to clean up my back yard as much as possible. We have a problem with water rolling down hill and carrying a lot of mud with it and sometimes carving paths through the dirt during extremely bad rain storms. Often times the mud will end up on the patio and needs to be scraped up. Any tips on how to lessen the damage done by the rain?
I imagine having grass would help with that? We do get grass but it typically shows up a little later, closer to the middle of summer and even then it doesn't 100% cover up the yard, only about 75% leaving the back left 25% pretty much bare.
>>1137148
Grade your yard to face away from the house?
Build a wall infront of your porch...
Wtf is with those retarded steps down? Id fill that with dirt so quickly.
>>1137151
Just the line separating the yard from the patio
>>1137148
definitely grass, unless the dog tears that shit up
otherwise, mangrove
I recently got wasted and threw up on the carpet. I did a poor job of cleaning up, and the next morning I blotted with paper towels and poured baking soda on it. I let it sit for a few hours and vacuumed the stuff up. What's left is a still moist carpet with baking powder mixed in. It hasn't dried yet.
Should I add more baking powder and let it sit for longer? I'm going to get a dehumidifier as well. I want to clean this myself instead of calling a cleaner to come over
>>1137053
Baking soda**
Sorry about that

I have a dog and a cat and an extremely sensitive nose. Also I'm a HUGE neat freak. There have been times when they throw up in the house due to illness, etc. Also when we went through potty training phase there was lots of pee. I tried everything I could find, carpet shampoo, pet and stain odor remover, pet and stain pee remover, etc. I literally bought every brand on the shelf and did many trials to find what would actually work. Like I said I'm a huge neat freak. Some would cover the pee with a stronger smell, but it would still be there and so was the discoloration. Or some would rid of the pee smell, but the discoloration would remain. Or some would take care of the discoloration, but the pee was still there. I would clean it really good, let it dry, then put my nose on the carpet and smell and also visually inspect where the accident happened. Of all the stuff I've ever tried, Eco-88 is the only thing that 100% got rid of the pee, poop, throw up, etc. AND remove the stain. Pee, throw up, etc. is acidic so I guess this stuff is a really strong base? From what I can tell when it comes into contact it starts bubbling immediately. Reminds me of peroxide on a wound. I think what happens is the acidic vomit/pee contacts with a strong base and basically turns it into a neutral like water. Plus there's some other chemicals that removed the discoloration. I'm not sure how it works exactly, I can just tell you that it fucking works amazing. I usually spray pretty heavy so when it's all done there is leftover like, peroxide smell where the spot was. Take a wet rang and wipe it over the spot to clean the excess Eco88 out of the fibers and your good to go. Spot removed, smell gone, acid neutralized. Full disclosure this stuff is superstrong. If you get it on your skin it burns like a thousand needles and turns your hands white. It's 100% a chemical burn, that's how strong it is. But it fuxking WORKS 10/10 would highly reccomend

So recently I happened to open up a crockpot that had been gifted to me (would've been rude to refuse, despite the fact I already own a bigger and better one) and I noticed that in between the heating element and the thin, metal exterior there is... nothing. Not only does this strike me as odd since once heated one could burn themselves touching the outside, but it seems super wasteful energy wise. These already suck up a shit ton of electricity, so why is the heater heating up the outside as well as in?
So I ask: has anyone ever heard of adding insulation to the inside of a crockpot/slow cooker? Can you think of any reason why this *wouldn't* be a good idea?
>>1136991
>These already suck up a shit ton of electricity,
>crockpot
wat?
>>1136991
You expect chink shit to be throughfully designed?
>>1136991
>These already suck up a shit ton of electricity
Tell me, do you expect that you pay more or less than ten cents for the electricity to make a slow-cooked meal?
>Can you think of any reason why this *wouldn't* be a good idea?
Because the cooker is designed to maintain a suitable thermal equilibrium at its heat output to slow cook food and keep itself cool enough to avoid internal damage. Adding insulation would produce lower side wall temperatures and higher internal temperatures. This could in principle lead to unsuitably hot cooking and damage to wiring.
I want to build a wooden foot locker to store guns in. It needs to be fairly portable but sturdy. I really like to way pic looks. It's from the tv show Arrow.
>>1136987
Good for you. All the best with it anon.
OP here. Does anyone know a good set of plans? I can probably wing it with success, but plans would help.
>>1136987
>fairly portable
Nope. Notice how long that is, and the handles on each end. It's meant to be carried by two people and put on the floor where you need it. It's not really meant to be carried around like a briefcase, especially when it's full of stuff. That being said it looks pretty straightforward. I don't think plans would be necessary in this case. All memes aside looking at those planks on the side, pallet wood might actually be good for this.
Need some help..
I am installing a ceiling fan.
I removed the old electrical box. I attempted to install a joist brace to hold the weight of the fan, but the hole in the ceiling is right next to a stud/joist, preventing me from using it. I would move the hole over, but there are 2x2s in each corner, and this brace wont work with the 2x2 there.
Id just nail the box/mount into the stud, but i dont think i can secure the electrical box/mount on just one side, doesn't seem safe, but i'm not a carpenter or electrician.
Any help will be appreciated.
use one of these?
http://www.homedepot.com/p/15-5-cu-in-Retrofit-Ceiling-Fan-Saf-T-Brace-0110000/204845572
>>1136999
thats exactly what I had.
the problem is, each end of that brace, is about 3" tall. so whatever its pressing into, needs to be at least 3" tall. My issue, is that there is a 1x1 or 2x2 piece of wood in the corner where the sheetrock and plywood meet, not allowing the brace's teeth to grab onto the wood, it doesn't touch anything.
but this is exactly what I need.
Thanks for the response though.
