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.

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!

Sorry for the pain you're going through. Building a house is known for stress.

Why do you think it needs 200 amp service? This size house might be ok with 100, especially if you cook with gas.

I put in this 1/2" MIP drain plug with a square head (for a showerhead) before I did my tiling. Now that I've finished tiling and am ready to install the showerhead I realized I don't have a socket that fits this head. Do any exist? Is there another option to remove this? I've tried getting a channel wrench and vice grips in there and I'm chipping the tile.

Hey all,

I do a bit of metal detecting and find tons of these 22lr shells. Got 2 small jars full of them pretty much

Any ideas on some diy project i can use them for?
I was thinking about reloading them just for shits n giggles but it really isn't worth the time and money.

0. Electrics ≠ electronics. Mains wiring goes to /qtddtot/ or /sqt/. PC assembly to >>>/g/.
1. Do your own homework. Re-read all documentation/datasheets related to your components/circuits, and do an honest web search, before asking.
2. Pics > 1000 words. Post schematic/picture/sketch/9001.5 hours in MS Paint with all part numbers/values/etc. when asking for help. Focus/lighting counts.
3. Read posts fully. Solve more problems than you create.

>I'm new to electronics, where to get started?
It is an art/science of applying principles to requirements. Find problem, learn principles, design and verify solution, build, test, post results, repeat.

You can average as you like for cosmetic reasons, but that doesn't affect the accuracy which remains unknown until measured. Also this:
"The resolution of the temperature sensor is user-configurable to 9, 10, 11, or 12 bits, corresponding to increments of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C, respectively. The default resolution at power-up is 12-bit."

What is the best way to get these cleaned, derusted, and seasoned to a useable state to cook with?

Was gonna maybe run them through dishwasher, scrub them down with some 60 grit sandpaper, soak in some vinegar to get fine rust off, slather in shortening and put in oven at 450F.

>>1514109
sit them in vinegar for a day and see if that gets the rust off, any that doesn't wipe away get a wire wheel and scrape it a bit and soak it again.

Then season them and use them like normal.
>>
>>1514109
i've seen several good YT vids on this exact thing
>>
Vinegar. Or wire wheel on drill or grinder. Or elbow grease and 60-320 sand paper.
You can try rust remover, but keep in mind, that shit is poisonous, so you have to clean it really good before seasoning, while sandpaper doesn't require much cleaning.
>>1514137
Cast iron is the best thing you can get. Shit doesn't stick, doesn't kill birds if overheated.
Stainless is good too, but is more sticky.
>>
>>1514914
Or citric acid, if you can buy it.

Vinnegar has been added to my cleabin supplies. I go down to the dollar store.
Just soak it for 24 hours in vinegar .

Does anybody know what these are worth? I had an electrician and his dumbass apprentice come fix a power outlet and they left these here. When he called and asked if I seen them I said no.

someone should go on social media and post this guys name and ask if any electricians did any work for him and see if anyone responds and then tell them he was bragging about he had their equipment and told them he didnt and wants to sell the shit instead of giving it back. I bet they will go back to ops house and rape his asshole
>>
>>1514855
>rape his asshole

but electricians are smart enough to know that is a bad idea, if they really did leave a pile of equipment in his house, and all he did was lie about it.

I for one think the story is fishy because you don't use a scope to fix a receptacle, much less two meters and an assistant. OP broke into someone's truck or shop and grabbed what looked valuable.

Flukes have internal serial numbers.
I had one of my stolen a few years back. It had a small defect as in the LCD had drop outs. Thief (or someone that bought it from the thief) sends it in for repair. Fluke fixes it, notices I reported it stolen, contacts me, and winds up sending it back to me fully repaired with calibration.
It's nice having a meter with a lifetime warranty.

do you have harder evidence of rockwool usage being dangerous?

Since you are nothing but a lowly technician, let me spell it out for you:
Radiation is a silent killer. Nowhere did I make mention of how or why it is killing you, so to bring up acute radiation exposure is nonsense. The way a layman would be harmed by radiation is through unsafe handling and prolonged exposure. For example, one many people are familiar with, consider radon gas. Radon gas in your basement is a low concentration that it will not give you acute radiation poisoning, but the long term effects of breathing in this radioactive gas is damaging. If you really were some rad-tech at a powerplant, you would know the three critical elements to radiation exposure: time, distance, and shielding. A layman is likely to spend a very long time very close to a source, without shielding. Those who are not familiar with radiation, not knowing the differences between absorbed and equivalent dose, activity versus fluence versus exposure, should not be handling radioactive material. Maintaining ALARA for these individuals means avoiding exposure in the first place. Radiation is a silent killer. You do not feel immediate feedback that what you are doing is wrong, so without the proper knowledge, measuring/monitoring equipment, and dosimetry, it is best not to tinker with radioactive material.

You do know, it’s not that they are dangerous, but with only a moderate amount of protection they can be rendered null.
While you try and make us more radium girls, just know that being a dumbass and bringing up dumbass arguments does not win you the argument.

for blacksmithing you only need heat, anvil ( anything to hit metal on), hammers to start out. Learn to draw points, make nails and stuff.

for gunsmithing you need a $10-20K machine shop and years of practice
>>
Modern gunsmithing is machining more than anything.
Although youtube.com/watch?v=qTy3uQFsirk is one of the coolest demonstrations of craftsmanship I've ever seen, so it you're fine with more historical stuff and working painstakingly slowly you can still do fully "handmade" firearms. Its something I've always wanted to try but the time investment required is immense.
