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:https://sites.google.com/site/diyelmo/ (archived)http://www.engineeringtoolbox.com/
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!
Why are so many Americans willing to pay for someone else to mow their lawn?
>>3004022The only people I've ever known to have it done are the very wealthy that have them as a landscaper or the old and infirm that cannot manage to mow it themselves. Normal guys just cut it themselves.
>>3004022I wouldn't be suprised if this was economically sensible.You must look at the cost of opportunity and economy of scale.You must not only pay for the mower, its upkeep and fluids. You must also either buy or rent the space you keep it in. Lastly and most importantly you must evaluate your own time. Your job pays more per hour than Jesus job (which id mowing lawns)? Go work in the meantime or enjoy your free time doing what you really want.>inb4 I simply have the spaceThat's not an argument. In a perfect market economy you could sell or rent it or you should not have bought what you didn't need to begin with.Economy of scale is self explanatory.
>>3004041Why would anyone go to work when they can just mow a lawn?
>>3004041please let this be bait.

>>3004033>Show us more details of that mouldOf course!Here's a few views of the CAD model that show you the internal structure. I maybe should have made the sprue/runner larger for the highest point to allow air to exit on its own because the silicone was too thick for that to happen naturally, but I didn't want the trim-away spot to be bigger than it was. As it was, I just let the pour settle for ~20 minutes and injected more silicone through the hole for the lower sprue to force the air out.You can also see the holes I included for four M5 screws to hold the whole thing together during curing, which resulted in only a very thin flashing layer which broke off easily. There's another M5 hole in the top which I used to push the two halves apart for demolding.

Not my pic, the roots in question started pushing up pavers in the middle of my driveway, without affecting the outer edges. For now, I've pulled up the affected pavers, cut the roots out enough to not have to pull up the whole driveway, poured some glyphosate on the end of the root, and put the pavers back down. Ultimately because I'm not using a plate compactor, I can only lift my pavers X amount of times before they will be noticeably wonky.I know some people will lightly spray their pavers with glyphosate to stop weeds, but does anyone ever use a heavy dose to try and soak into the earth below? I'm thinking of drowning the middle of the driveway in glyphosate, hosing it in, let it dry, hose it in again the next day, then just don't park or walk on it for a week. It only seems to be an issue since we had an AC unit installed that drains on the driveway, which I'm assuming is attracting the roots to be surface. I will address the drainage issue.How would you approach this issue?

>>3002758Pouring round up into the ground hoping it removes roots is much closer to afrixa in spirit than you might think.

I'm an aspiring woodworker and I want my own space for working my projects.>But I live in a tiny, shitty one bedroom apartment>I hate it with a passion>I'm also pretty sure it's making me depressed and resentfulWhat would be a good and cost-effective way to have my very own work space?I plan to move out and rent a house for my family and I.And if I can't ever get my own workshop space, should I just stop coping and get back to the minimal wage job I hate and despise?
>>3004044Idk I only do leather work, so no power tools. Some anon prolly knows.
Would it be too outlandish to rent somebody's garage for a workshop space?>Would that sound weird to a neighbor?Because I did check industrial lease prices and it's about the same price as rent in some instances>I ain't paying that
>>3004015Hand tools can be pretty loud still. Chopping mortises is loud work, as is banging the parts together/apart fire assembly. Certain power tools, like drills are far quieter than that. >>3004044You're only going to break cast iron tools like that if there dropping onto concrete.
>>3004065Mortise chisels are indeed loud as heckI remember when I was cutting mortises back in my trade school, even inside a loud wood shop it was loud and everyone looked at me for a split secondMaybe I should pad the walls with some acoustic foam
>>3003943Maybe find an option for a shared/co working space or rent time in a proper workshop. Use your home to make excellent prepatation (plans, marking) and/or do stuff outdoors.
Ive got this plastic musket I used for LARPing and it fell and broke. Its made of some kind of chinesium plastic with the cross being hollow but the other side not. I tried fixing it by using two part epoxy and hockey tape but it didnt last long. I need some kind of physical bond other than just chemical I think but I cant fathom what for some reason. Y'all got any ideas?
>>3003575This. Drill a hole in each part an inch or two and insert/epoxy/superglue a metal rod in there then re-form the outside with more epoxy or steel/stick etc and file or sand to shape and paint.
>>3003675So I did as you said, found a piece of steel near the train tracks and jammed it in there. Had to use a shim so it roughly aligned with the other side. It's pretty crooked but I used waaaay more jb quickweld than I did last time. Hopefully it works better this time.
>>3004000>jb quickweldUse thermite.
>>3004000anons were probably hopin you'd use a longer piece of steel than that
>>3004028Turns out beneath the white plastic is pure metal, i coulnt drill through it.
Let's get a gardening general going on. What are you growing? What are you building? Problems, solutions, and advice are welcome. Books, non-gay yootoobers, and other resources also welcome. If we get enough engagement perhaps even a pastebin is in order!
>>3003043wtf you doin mate?
>>3003215based>>3003624no. really just replace your lawn with them and clover
>>3003710I found a really nice stick while hiking and took it home. I shoved into a vacant large pot and left it for a while. Now its sprouting.Luckily it seems the area I was in is not a National Park or Forest.
>>3003711Already heavily seeding in clover and it's worked great.
>>2993981I don’t like gardening no more. Only a few fruits grow late in the season and that’s all.
A place for anything to do with Welding.Post your welds, ask questions and discuss sticking metals together.IDK I just want a place to talk about welding.Thread Theme: Wacky WeavesPrevious:https://warosu.org/diy/thread/2932874Previous before previous:https://warosu.org/diy/thread/2894379
>>3001787Pouring water on a hot weld is going to fuck up the internal grain structure of the weldment. The slower a weld cools, the finer and more ductile the weld will be. Conversely, quenching a weld will result in a course grain structure which is more brittle and subject to cracking. This effect will vary depending on the carbon content of the steel, but it's always better to never quench a weld unless you're trying some sort of heat treatment.>they just tack on the surface6010/6011 have better penetration characteristics of any stick rod. That's why 5P 6010s are often used for root passes on pipelines.>cursive C loopwill just add more heat, therefore distortion and melt-through likelihood than whipping. Stringers in 3 passes will introduce less heat to the weldment than a weave for the same final weld size. If the guy is having issues with burn through, then the fillet weld doesn't need to be big to begin with. There's no need to weave on 1/8" steel.
Got an interview lined up for my first welding job next week.
>>3003419Atta boy knock that shit outta the park. You can do it bro.
>>3003419Practice and weld then grind and bend some test coupons. Many community colleges let ya rent a booth for a day at their welding program to prepare if ya don't have a welder etc.
>>2972986So this boy is playing in a dumpster and finds a welding mask, so he puts it on and is running around playing with it. Then this pervert drives up, and he rolls his window down and calls the kid over. And he says hey kid wanna suck my cock? The kid say no.He says well, want me to suck your cock? The boy says no, no. He says well hey maybe you want me to put my hot cock up your tight little asshole?The kid says oh I see the misunderstanding here. I’m not actually a welder!
Had to buy a hot air gun for a quick job. Now im stuck with it seeing where to stick it or what to do with it.
>>3003312How hot do these Bosch ones get? We have a Leister big boy hand welder that gets up to 1100, and a hand held one that takes Bosch 18v batteries that bets up to 932.
Perfect roasted marshmallows every time.I also tried it for working confectionary. It was okay but it tended to apply heat too locally compared to a heat lamp.

>>3004049MOTs suck ass desu but youre sort of right. Can even bash the magnetic shunt out.Then again it's long ago that I was a kid picking through the trash to find fun toys. And new microwaves have shitty SMPS for the same reasons really.I guess there is still weight savings to be had.
>>3004030> on 3.8VJust use lion then i would think.Those vape things use rechargeable li-ion as disposable.
>>3004052Well yeah Li-ion is better, so why use NiMH in the first place? The only benefit is not worrying about battery management, you can drain those things to however low you want and they’ll charge up fine afterwards.

So /g/, I'm a computer guy first, and a very amateur electrician, but recently I had an interesting (to me) though. I was borrowing one of those electric kettle thingies with that circular base from a neighbor and I almost walked out of the door with just the kettle, and they joked passively about me not taking the base with saying that I could probably rig it to work without it, and that got me wondering if I can with maybe like a spare IEC 60320 C19 250V, 16A power cable. But, I can't find freely available specifications for KSD686-CF 250V, 13A online, which would be critical for an amateur like me to actually try to pull it off. Seems it's exclusively just chinese or russian sellers selling it with no specs.Do any of you know where I could find something like that? Sorry if this didn't deserve a thread.
>>3003930>It's probably as havingIt's probably as simple as* having
>>3003808why don't you just salvage connector from another electrical kettle base instead of gimmicking for no reason you fucking mongoloid
>>3003930>Basically pointlessly stupid shitMan you said it yourself. /thread
>>3003808This is definitely a nefarious use-case but I can’t tell what it is yet.
>>3003808Look: Just take a power cord, remove the appliance end, strip the qires back and shove in the bottom of the kettle. It will work. Easy as. If it trips the breaker clear the short and try again. Or just buy one.
Hello. I was unsure if to post this on /ck/ or /k/ but i'll do it here. I am doing a complimentary fork for my bowie knife i smithed. It'll use a bowie knife handle but smaller and with a fork on it.However, i am having trouble deciding what kind of fork it'll be, a two pronged one or three, what curvature on the prongs...Like, why are some forks straight, some curved, some slightly curved? What are the pros and cons of each? I just want a fork on a knife handle, but i have a teetering feeling forks are curved for a reason... but at the same time a flat fork would fit very nicely in a leather sheath (both knife and fork in sheath)....help!
what's your use case for the fork? are you just going to eat with it?
>>3004019How about food that you don't impale with your fork can rest in the depression?/thread
1. The proper past-tense is "smuth"2. "Some" curvature is the right amount. It will help you scoop things that don't lend themselves to skewering on the tines.3. It doesn't matter very much exactly because3A. you'll adapt to make use of whatever curvature it is, and3B. you can always adjust it later
>>3004043starting with a troll and following with actual advice makes a reader think the entire post is a troll
>>3004045I wasn't trolling, I was just being silly.Do you remember when people could be silly without it being "trolling"?Anyway you evidently saw through it, so others can too and decide for themselves if it sounds reasonable or not.Have a great day, Anonymous.
I'm a older webdev shitter who is looking to switch to a mechanical trade.Even though they were primarily looking for people with previous work experience in similar fields I actually got invited to an interview for a paid apprenticeship and did well enough, now they want to invite me over again to check my basic manual skills before offering me a contract. (I didn't hide or lie about my background or anything.)Is there any source I can use to at least gain some very basic knowledge on tools and methods or way to get some practice in? Any tips to prepare for something like this?Am I about to embarrass myself while young mechanics get to laugh at me?
Any updates anon ?

>>3001755How old? I'm retired USAF aircraft maintenance and loved it. I love the retirement even more since retiring after 26 years left me debt-free and job-optional which is glorious. You get excellent training (I enjoyed tech schools and variety so I was variously comm/nav, engines then merged with crew chief) and aircraft are far more enjoyable than the wheeled vehicle world. If no military option industrial maintenance and mechatronics are offered at community colleges if ya don't get hired right off. Those are fun and make you highly versatile.
I worked in an IT office for 15 years and was on the verge of suicide.Some people can sit, watch youtube all day, listen to old office ladies drone on about gossip and tv shows, but I couldn't do it.I thought I could, I THOUGHT I wanted to make money doing nothing.Turns out I was dead fucking wrong, those were some of the most miserable years of my life, completely wasted.To get my foot in the door learning mechanics, I quit my job in IT (this was back in 2018, so 8 years ago roughly)and got an entry level job working as a Golf Kart Mechanic.This was pure luck that I chose this job and it was one the perfect starting path.Golf Karts are like mini cars, and you can learn a tremendous amount about basic mechanics, as well as bodywork, by starting with them.There's fully battery powered Golf Karts, Lithium powered, Gas powered.One of the coolest things I got to work on and learn a ton from, was the very rare older 2 stroke Golf Kart that only a handful of times, came into the shop.After spending a few years cutting my teeth here, I was able to get a job assembling Composite Fiber Parts, building experimental aviation aircrafts. (very large unmanned drones, "airbus" competitors)They offered to train me to be an engineer or Quality Inspector but I turned it down.Comment too long. Click here to view the full text.

Last Threads: https://warosu.org/diy/?task=search2&search_username=artbyrobotTo begin: the project goal: I am working to make a series of humanoid robots. I am using a Biblical theme of naming the first 3 robots I make Adam, Eve, and Abel. The goal is for these robots to have human body inspired musculoskeletal systems, advanced AI, and that they look human and pass for human to a casual observer at least at a distance. They must be able to walk, talk, run, dance, do sports, do chores, manufacture products, and make more robots just like themselves if not even better. My aim is to build a single robot arm and head and then add sufficiently advanced AI to that arm and head to enable it to build the rest of its own body for me. This way I am delegating the work of building the majority of my first humanoid robot to that robot rather than doing that work myself - and this is to save me time.In a like manner, my goal with the AI is to code just enough AI that the AI can begin coding itself and this way I don't have to code most of the AI myself because it will self create itself. I liken this to building a seed and that seed growing into a tree because for me to code that tree would take too long for me and just creating the seed would then save me time.
>>3003690Is this the flex pcb you're working on? Don't you think a flex pcb should have flexible routes instead of flat, brittle copper plating?
>>3003763>Could we see some of your documentation from, say, 4 years ago?well my blog started in 2024 so to go back an additional 2 years from that, we'd have to look at my video blog which is my youtube playlist: https://www.youtube.com/playlist?list=PLhd7_i6zzT5-MbwGz2gMv6RJy5FIW_lfn --- which goes back 12 years. Beyond that I have extensive notes in my personal hard drive and drawings/schematics but you've seen all of those if you've seen the video blog.>you can spend even up to or more than 9 months on a single half bridge circuit, do you still assume it's realistic that you will finish this project? Why?yes. The past 9 months has been swallowed whole by my real estate investing projects with very little time and energy to spare beyond that. Also raising young kids is time intensive and energy intensive to boot. Other seasons of life will go way faster especially as the kids start helping more.> so there's no risk in the investmentthat's simply not true. real estate may go slow, other ways to monetize them might not pan out, the robots may not thrive in real estate, I could get banned from using them by new laws for things I planned to use them for, etc etc many things can go wrong. The risk would be enormous and the timeline of paying back a business loan has to be incredibly short or else fines, penalties, and interest starts to drive what you owe through the roof and you end up in a hole nothing can get you out of and you have to file for bankrupcy etc. It's a foolish suggestion by you.>500k of R&D money should do itthat's like a 2 month runway if you were to hire engineering team and go a full speed. You've have to get like a 100 million dollar business loan to build a large team and have the years necessary to build it and what about the AI. That's a decade or more so add a good $1 billion dollar business loan to hire a large team of AI devs for decade. Nope I don't qualify for billions in loans.
>>3003764>Let's hear about the rest 47.artbyrobot.com/blog>do you think knowledge about spacing out smd components is quality knowledge worthy of a revision of the whole project? yes>Can you provide us with some examples or excerpts?no too much work>>3003766Is this the flex pcb you're working on? Don't you think a flex pcb should have flexible routes instead of flat, brittle copper plating?yes its flex pcb and no, you don't have to flex a flex pcb it just enables you to flex it if you want in some cases. The primary reason for using it is it is thin so takes up less room. A rigid pcb is super thick by comparison and wastes space. They don't make ultra thin rigid pcbs that I am aware of.
>>3003897>we'd have to look at my video blog which is my youtube playlistSo you're saying that this playlist and paint/gimp drawings of circuitry that you posted itt are your notes and by the time you're 90 you're going to look these up to refresh your memory?>> so there's no risk in the investment>that's simply not trueSo in short you're just simply right and excel at every step of your venture but everyone else most likely will be at fault and ruin you if you take the loan - is that correct?>>500k of R&D money should do it>that's like a 2 month runway if you were to hire engineering team and go a full speed. You've have to get like a 100 million dollarSo you're essentially claiming your current work on the robot is worth 250k a month? Is 100 million the budget for the whole robot or the arm alone?>>Can you provide us with some examples or excerpts?>no too much workFew postsa go you copied and pasted some chatgpt ramblings in this thread and now it's too much work? Is there some kind of rule to how much work it takes to copy chatbot chatlog at a given point?
>>3003898regular pcb is less than 2mm, you're not saving any space, you don't even have any actual design document with measurements that requires you to use thinner boards. All you're doing is wasting material in order to crank out messy garbage of no use that has no advantages of a flex pcb (flexibility) and no advantages or rigid pcb (rigidity)
