Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Helpful links:
Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

I've made a tutorial on how to quick fix your alarm clock in DIY style! Enjoy!

oh furfuxake, you take the steel balls out of the mix before packing it, you actually really that fuckin thick?

nope, niether will reach the required ignition temp.

It's shit you can learn how to make on youtube. They're pretty fun. I made little rocket kits when I was in boy scouting. They're pretty fun.

Do NOT fuck with liquid oxygen, that shit will turn anything into a goddamn bomb if any spills.

My roommate accidentally picked up some automatic dishwasher detergent and we don't have a dishwasher.

What else can I use this for? It sucks for handwashing dishes.

It's great for cleaning grease off chrome on engines etc
Soak your oven shelves or other stainless steel over night in it and hot water to get a nice shine
Blinding your enemies

I personally hate washing dishes by hand.

But what I hate even more is having to prewash shit for some shitty dishwasher that hardly ever does the job right.

I'd prefer to do it by hand.
It's basically a low foaming soap.

I have a machine but sometimes wash by hand if there isn't that much or I've something that the machine might harm, I don't mind it as it's sort of relaxing.
Awesome for washing cars, really good shit. Kirkland though, so can probably return it
Yeah, I knew I could return it, but Costco is an hour away and I wanted to see if there were other uses. It looks like everything suggested is either not relevant to me or I have better products for the job.

How to get rid of ice dams?

I went on vacation for a week and while I was gone, there was a lot of weird weather, so now I have ice dams. I've thrown RoofMelt up there and scraped as much off as I could. Would it be too late to get the heated cables at this point? Any other suggestions?

How long ago did you do this because salt takes time to work?
Maybe 20 minutes ago. I know it won't be done yet. I was just wondering if anyone knew of a really good method for getting it off.

Salt is fine, but to address the root cause: poor venting and/or insulation. Get it fixed before your new house becomes a shithole
Yeah, that's the plan. On inspection, there wasn't anything wrong. So I'll have to crawl back up there and see what's going on. For now, just trying to get rid of the ice dams.
If you want it to melt faster you can make some holes in the ice with an ice pick or something and pour salt in the holes.

Seems like it might be too much effort though.

look at this little turbine. It provides like a hundred pounds of thrust.

I heard there's a jetpack out there that has a 9 minute flight time.

>to your legs
I have a better idea
I discussed the possibility of a drone hoverboard on /sci/ and they became contrarian as usual. Seeing as /diy/ is open minded enough to discuss jetpacks do you think there should be more research done on human lifting multirotors? One guy from Canada famously stood on his octocopter for 1 minute last year.

Maybe not multirotors in particular, but yes, I'd love to see more kinesthetically-controlled personal hovering platforms. I think it's very doable at the amateur-built level.

No. Human lifting multirotors* are just a meme. A multirotor 'hoverboard' has no practical uses.

*definition of multirotor means 4 or more propellors

Do all drill presses sold new today come out of the same Chinese factory? They are all the same and they all have horrible user feedback on Amazon and other review sites.

How best do I acquire a good American-made drill press without spending much? There are some ancient Clausings and Buffalos on Craigslist but they all cost a fortune.
8 replies and 1 image omitted. Click here to view.
yes. the cause for the move to manufacture in china was brought about by the solid american and german built tools that never break down. if someone wants something that just works forever, they just pick up a used one. if they really want a new one, not that you actually need one, the desire for a new tool is skewed by the cheap chinese shit that breaks down after three years, you buy a chinese one.
>Do all drill presses sold new today come out of the same Chinese factory?
the consumer-grade ones, yea. pretty much
>How best do I acquire a good American-made drill press without spending much?
you don't. with machine tools, a safe assumption is that a first-world-quality item will cost around 5 to 10 times what the cheap China-made one does.

(as far as the USA goes) the better China/Taiwan brands are Jet. nearly (but not quite) as good is Grizzly.
the worst ones are the cheapest ones--HF, northern tool, ect.
once you decide what you want, shop around for comparable items and let the prices be your guide.

>There are some ancient Clausings and Buffalos on Craigslist but they all cost a fortune.
those aren't necessarily good, just ancient.
old equipment can be worn and damaged, even if it is high quality... and even if you are willing to bother, [new] replacement parts may not be available.

>first-world-quality item

While I don't mean to stir shit here some of the shittiest products, including tools, I have ever come across have been imported from America and were twice the price of a significantly better ching chong wing tong brand item.
I'm not about to claim that some of what we make isn't shit, but
Most of the stuff that's properly, actually entirely Made In America is top quality.

Assembled in America (or any other lesser labeling) is usually the cheapest of the Chinese shit that someone imported to here, put two screws in, then resells based off of muh American Pride.
>While I don't mean to stir shit here some of the shittiest products, including tools, I have ever come across have been imported from America and were twice the price of a significantly better ching chong wing tong brand item.
I don't doubt it. ...what country you in?

In the last ~20 or so years US politicians have been pushing tax breaks to "bring jobs back to America". So now you have US companies doing some manufacturing of the things mostly made in China.
The items only cost a bit more or the same as the Chinese ones, but the difference is in the wages paid to the workers: when those jobs left the US they paid $50+ an hour w/lots of benefits. The returning manufacturing jobs in the US tend to pay more like $15 an hour with little or no benefits.

I guess it would be better to use the term "industrial quality" rather than "retail quality".

Hello /diy/, this is the only heat source in my new house. what knob i have to turn to controllo it? if i turn too much they fucking come away
fucking phone
Don't my neighbor's house burned down because of one, they lost their 5 month old child and dog. My neighbor, her husband and their other two kids had to be treated for burns and inhaling smoke. Literally the house was turned to nothing, then sold behind their backs by the owner and built over
Get an extra blanket on your bed, a hoodie to wear around the house plus some nice slippers.
Or you could just not be a fuckwit and put flammable materials next to an ignition source.

Put it on a table where it's not going to be knocked over, don't put it on carpet or close to your bed linen, FFS.

Bonus points for getting one with tip over and over heat protection.

My electric dryer isn't getting hot enough. It's probably the heating element, this one is like $25 to replace BUT I have another new HE for a different dryer that does fit and looks almost the same but is a different model number.

How safe would running a different heating element be?

hi /diy/,

I recently used a raspberry pi v2 in my computer architecture course(because MASM doesn't really let you get that low level anymore), and now i'm wondering what I should do with it, now that the course is over.

Does /diy/ have any project recommendations? What should I do with it?

Also, share your projects if you have any.

I'm using motion to stream a webcam from my Pi but it only runs for like 2 secs then cuts out. Anyone else mess with streaming video from a pi?
Might be a power situation. Look into getting a powered USB hub for the webcam and wifi adapter if you're using one.

Maybe you are buying junky SD cards? I have three and have never had an issue.

Ok, I'm just going to see if it works following the OpenPandora set up later after work. I would love to have a "dedicated Starcraft machine."

So just a thought who knows some cool experiments with chemistry
21 replies and 2 images omitted. Click here to view.
So far I've strictly only worked in lab settings.
HF is pretty nasty shit.
Thankfully so far I've only needed to handle it twice in small quantities, last week someone got some under a glove in our uni's lab somehow and was rushed to the hospital.

Aside from megatoxins like certain organo-phosphates, the only chemicals I am shaky around are contact poisons. Especially the ones that can eat through most barriers.

Practically everything else is treatable unless you fucked up bad.
I work on a site with ethylene/propylene oxide. Shit's pretty scary.

I need to get out of the lab. We don't normally use that bad of stuff. Worst stuff I think we have are 1% HF solution somewhere I think, Potassium Dichromate, Nicotine, and some other nasty acids. Thankfully I don't use them, but I don't trust my coworkers who do.

I'm too paranoid for this job.
I was offered an internship at an industrial plant once.

I declined because the parent company had a history of not performing critical maintenance that involved systems that deal with very hazardous materials.
you sound like a pussy. Copper salts are not really toxic, and if you weren't wearing gloves you're just retarded.

MakerFarm I3s use them, some Deltas use them.

They are just plastic rollers with bearings in them, you buy the correct ones for what type and size of extruded aluminum you have.
Looks like a Makerfarm Pegasus. Should be a good design.

They're wheels for aluminum v-slot extrusions. Every bit as good as linear bearings on a rod. Some core-XY designs use them and they're good.
Would these fit 30x30 item profiles?
they are rounded not chamfered

Hey guys,
Quick electrical question.

I have a 220v outlet with a 30 amp breaker. Can I plug a 220-110 step down transformer to the the 220v outlet and run more than 30 amps on 110v?
4 replies and 1 image omitted. Click here to view.
If you're in the us you don't need a transformer, you need a plug. One side to neutral is still 110v

you're confused. the rule of thumb for a x-former is 'power in = power out', so 60A on the secondary only requires 30A on the primary to make the equation true. the breaker will not blow with 30A on the secondary, coz it's just passing the 15A the primary needs.

Here we can get 6000 watt output 220-110 stepdown transformers off the shelf in your average hardware or electrical store.

While they are expensive they are fairly compact in size 10"x8"x6".
you're right, i see. i only looked at the 30A breaker, thst surely will trigger in the current exceeds the 30A. But with the (step down) transformator OP will get 60A@110V - or 120A@55V and so on. my fault.
what are watts

This is an old shower drain in the basement that I don't plan on using. I had a water problem at one point which is now fixed, and water would pool up in that divot. I was originally intending to take it out, so I drilled the hole into the pipe for water too drain into it. Now I'm not taking the pipe out and I want to cap it with a clean out cap. What would be the best way to seal up that hole in the pvc without chiseling out enough cement to slip on a coupling to cover it? I don't expect it to ever back up, but just in case it would be better if the hole were waterproofed.
That should be enough room fairly easily to throw a coupling on.

I am sure the clean out will fit right over it.

what you have to check is if it completely covers the hole you drilled.

hello /diy/
i have old dr martens boots and i want to do something similar to pic related to them (pic 1 or 2, haven't decided yet)
so can you tell me what is the best way to do that, which materials/techniques to use?
15 replies omitted. Click here to view.
This is so gay. Steel toes are for working men in an industrial field. In fact, worn out boots that have steel exposed is a no go due to possible sparking. I work in explosive gasses environments. If I saw those boots I would fill em up with ben gay and wait for you.
They didnt start being garbage until about 2005 when they changed up all their lines, started selling a bunch of chinese ones. Their sales plummeted and they needed to entice people to buy them, a sharp decrease in price.

I bought a pair when they used to cost almost 200$ in 90s money.

I think what OP is doing is dumb.
>buy second hand steel toe boots
>cut them open
>remove steel toe
>Polish to high shine
>glue to the top of your boots

You now have the black pair of boots in OP
Because steel rusts you dumb fuck. You are asking for rusty metal and wet toes
