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!
Any advice?

>>2791830Do it. I took a class at the local CC and I can now Stick, MIG, TIG and Flux Core weld. I can also set up and maintain the machines. Feels good man. Also the instructor, his assistant and the people in the class were all p cool. A couple guys got their certs while we were in there, which was awesome.
>>2791830>>2763067
>>2791830Don't flux core weld without a respirator. Mig and tig are only bad if you really huff the fumes or stick the inert gas line up your nose, and stick is a little more nasty, but flux core will kill you.
>>2791830Its a fun time in my experience. Had a great instructor, learned to weld, met chill people, all felons but chill ones.
Seems like everyone and their dog is now importing and selling Chinese mini diggers.>picrel sells for $12k>small one for $4-5kSo standard retail margin of double what Cheng sells them for.Any equipmentanons have QRD on this?Should I buy temu digger for my kids?Is it gooder or worse than my woods PTO backhoe?
>>2791161that's a yanmar pump?the machine that everyone is creaming themselves over uses the same gear-type pump that chang uses? wtf?besides being 3 ports instead of 1 how is this 4-5x better then changs pump?
>>2791166Cheng has been getting betterGo with a Rippa or Infront or similar
>>2791166>that's a yanmar pump?No, that's a replacement pump made by Cheng for Yamaoka's excavator.
>>2786449why is no one making them state side if the margin is so high? labor??
>>2792155mainly the engine cost. USA has trade protectionist policies ( aka EPA standards) to prevent Cheng from dumping his diesel engines here.Cheng's diesel engine is no Kubota, but it does the job just as good at 1/10th the price

Don't be a faggot and use a $5 pour over funnel >only use filtered water a cup of coffee is 99% water, if you use dog shit water you're going to wind up with dog shit coffee pic related is genuinely all you need, and you get the lead glaze for free. Anybody who thinks you need more is either deeply offended by anonymous words on an anime forum or are wannabe internet influencers who have something to gain personally or financially by convincing retards that you need complex machinery to make coffee We've been making tea for thousands of years now which thousands of years of technological development and technique refinement now amounts to "just fucking put the tea in hot water whats the problem" Coffee is the same but, again, preground coffee goes bad MUCH faster than tea so coffee teabags aren't feasible but do exist
>>2770075Coffee brewing involves three things. Water temp, grind fineness, and extraction time. What you need of each factor depends on your brew method.
>>2770085hot water, ground coffee, filter(optional) yall are making it to complex

Previous thread:>>2759901Here we discuss microcontrollers (MCUs), single board computers (SBCs), and their accessories, such as Atmel mega and tiny AVRs (Arduinos), PICs, ARM boards such as blue/black pill STM32, ESP8266/32s, RP2040, Raspberry Pi, and others.For general electronics questions (power supplies, level shifting, motor driving, etc.) please ask /ohm/.>where can I find verified quality microcontrollers and other electronic sensors or partsdigikey.commouser.comarrow.comnewark.com>but that's too expensivealiexpress.com (many parts here are fake, particularly specific parts out of stock in the above sites)lcsc.comComment too long.

>>2791827STM32s are definitely more powerful than 8-bit AVRs. Though the word "arduino" no longer just refers to 8-bit AVRs, they've released official boards with Renesas somethings and Microchip SAMD-series MCUs on them. The important thing about STM32s is they're used heavily in industry, and they have a very wide variety of chips running effectively the same architecture. Once you've learnt to program them efficiently, you can find an MCU for basically any project you want. The bad thing though is the boards from alibay are often fake. See:https://github.com/keirf/Greaseweazle/wiki/STM32-FakesYou also may not need the extra power of the STM32. Personally I've barely ever never needed more power than an ATtiny can provide. I bought a bunch of CH32V003s and CH32V203s just to mess about with though, they're neat chips.
I'm trying to connect arduino to a motor controller via uart. the controller is 3.3v, but 5v tolerant.sending commands to the controller works great, without any issues.receiving commands does not work. Serial.available() always returns 0.I tried looking at the rx and tx lines with a logic analyzer. when i have everything connected, tx from arduino to rx on controller works fine, i can decode the commands sent. the rx line on arduino always stays high though. if I disconnect the rx line from arduino and look at tx from controller, the line works fine then (i receive the response im expecting).Why does the signal (response) disappear when i connect everything? is there something holding arduino rx high?Also, the rx led on arduino does flash when im expecting a response, but logic analyzer and arduino does not see anything. Do i need to rip off the ch340 chip? is 3.3v not enough to register?
>>2791780>“boots into the gpu” so we don’t even need arm cpus anymore.for whatever reason the gpu boots first but then hands over to the cpu. so you still need the cpu.
>>2792012Thanks. Sometimes i wonder if those PC GPU cards have more power than the processors nowadays, lol.I remember getting my first laser printer in the 90s and i read the specs and was disheartened to learn it was a powerpc processor way more powerful than my actual PC that was driving it through the centronics parallel port.
>>2791963You can’t use the Rx and Tx lines for UART, they’re already tied to the CH340 and UART doesn’t work as a bus like I2C does. Set the UART to alternate pins instead.

wonderful. do you post off-topic bullshit on other boards, or just this one.
>>2787750Do you always get molested by everyone or just your stepdad?
>>2787747What union?Unions seem like the best gigs if you live in a city with a lot of big commercial or public infrastructure jobs.It also seems like union workers of all trades are basically just glorified laborers. Take the union's approach to concrete work for example. You have 'carpenters' for the forms, 'ironworkers' for the steel and 'cement finishers' for the finishing of the concrete. All of these guys are only skilled in one part of the process and that one skill is really pretty narrow. Like can you really call yourself a carpenter if all you can do is set forms? An experienced non-union concrete worker can usually do all 3 of those things.Or what about electricians? Half of the union electricians wouldn't even know how to wire a 3-way switch because all they do is bend conduit and pull wires. Are they really electricians or just laborers?
>>2789591>screw some 2x4s together to make a square>"carpenter">slop some rebar down into the square>"iron worker">cement finishersyea ok i'll buy thatthe other ones tho fuckin lmao
>>2791534I mean even cement finishers it's sometimes a stretch to call them that because like for instance the guys that do the freeways out of concrete just get those huge machines to do the finishing for themyet we still call those people cement finishersunion labor is kind of a joke, it's hard to imagine that they get paid so much
Trade Jobs Are DYING OUT...https://youtu.be/6DRm86qmXbs?si=BXi150ZR0VYKCqdQWhy is this so ???? >inb4 >yea low pay is going to be one of the main factors.https://www.npr.org/sections/ed/2018/04/25/605092520/high-paying-trade-jobs-sit-empty-while-high-school-grads-line-up-for-university
>>2791783Trade jobs are for retards who can't figure out how to become a licensed contractor the reason they don't pay much these days also immigrants who come and work non union jobs making it hard to compete plain and simple, to become a union journeyman and travel to job sites that pay top dollar u need a number of hours to complete as an apprentice from 3000 to 8000 plus school to qualify for the license exam, if u apply to a union u either have to be lucky af if there is demand but usually u have to have family tied to that union to get into their program, if u're young, have no experience, want to have a creer but can't go to college for whatever reason check ur local union halls and learn about these trades, in boomer days doing this and just working in the union as many hours available got u a comfy life and very good retirement, today u need to learn the trade and get out as soon as possible, that's what my formen told me and that's exactly what i did, i also went to college for construction management and gc to be able to to get better contracts for my businesst.ibew master electrician
>>2792039You've definitely got the "barely literate tradie" thing going.
>>2791790Im not boomer old but I'm millennial old who has had a business for now 15-20 years, have trained many workers and also been that bottom of the rung worker. Don't take it personally as I may be misinterpreting but. >Taken advantage of Usually this means doing the shit nobody else wants to do. This isn't "taking advantage" it's just parts of the job that have to get done and somehow the guy who just joined with no experience thinks it's mean to make them haul material for half the day and watch us work for the other half. This is normal. It sucks, but it's not some cruel act. >Expect to know everything as a beginner It's true that once you are in any trade some things are so obvious you forget what someone who is fresh doesn't know, things as simple as hunting for water on a job, how to push a wheelbarrow up a ramp, how much water should be in a sponge when grouting etc. simple tasks we do expect you to know and it's a shame when a boss is a dick about it, but...they are gonna be a dick fine, tell them to get fucked.>Being condescendingIt took me a while to fully grasp that my boss wasn't just there to do a job and run the process, there was a lot of risk, reputation, finding work so you can feed your workers and yourself etc. Once I was on my own, it dawned on me that every boss I told to fuck off because they were mean we're just stressed plus some lack of social skills and education, all they knew was construction from a time where they were allowed to just rant sexist, racist horrible shit at each other all day. >Things changing If you don't want to deal with the above, join a union and play by the rules, youll have managers and supervisors to complain to and that'll be that. The dinosaurs are being replaced. Personally the best quality work I've seen are from the mean, ogre of men who are difficult to work for/with. But you learn the most and you are given opportunities that can accelerate your skills faster than a union setup.
>>2791955This. It's the opposite, there has never been a better chance to replace a hoard of dying masters. I'm in my 30s, look literally like a homeless person and have so much work via word of mouth I don't know what to do with myself. All my clients complain they can't find workers. What I do see happening is that big builders are being dicks, the old men knew that when you had a good crew, you kept them rain or shine. Their kids took over, hired lawyers and accountants and now fire everyone to save a dollar here and there. Project ends, mass lay off, replace with the lowest paid worker, repeat. So if you want to do well in any of the "basic" trades like carpentry or painting etc. you have to serve only the super rich, who actually pay for quality. That or you specialize, specialized electrician, HVAC, technician work for elevators or other mechanics etc. Besides those two spheres being a tradie just sucks.my 2 cents anyways
Okay so i have experience living in Australia and southern California and here are my opinions on the trades situation in both of these places>AustraliaTrades definitely not dying, like 1 in 4 guys from my high school went into the trades despite life as an apprentice being absolutely shit for most people.Certain trades definitely have shortages, like bricklaying, hardly anyone young going into that trade and that's probably because of the reputation it has for being rough. Well it's a shame but its a dying trade anyway so I guess it doesn't matter, everything that was once built out of brick can now be formed up by a carpenter and poured with concrete. It'll be ugly but so is everything else modern so whatever. The reason they say there is a trade shortage is because they are importing a million brown cunts a year and they need white people to build houses for them because these brown cunts are useless and can't do anything except consume.>Southern CaliforniaNot really a worker shortage, just a shortage of good workers. Retarded brown people who can do a bit of everything are a dime a dozen but not many truly skilled craftsmen around. Parents from middle class families dissuade their kids from going into the trades because the trades are seen as a thing that mexicans do and not white people. Also the young white people here are fucking retarded and not reliable, none of them really understand that while the pay may be average at first if you put your time in and learn the trade you can easily be charging $50-60 an hour for yourself in like 4-5 years. And most trades are going to be paying like $25 an hour starting so way above minimum wage.
1. Can I put up drywall on this box or does the bottom need more support than the 4 corners?79in long (6.6ft), 24in wide (2 ft)2. Do I need support for the drywall all the way to the edge to the wall where the railing is coming out of (14.5in long gap)
>>2791531> they might have a point about keeping the doorAgreed anon. They probably think someday they will move out and they want the option of having a garage again.
>>2791787There is no door left
>>2790766OP you are going to spend way more in materials to cover the rails and lose head space in the garage than just cutting them off and buying new rails if they were to ever be used again.cut them off, man
why bother framing them in at alljust use them as a clothes hangerconverted garages are already white trash so you might as well embrace it
>>2791803> And keeping the garage door intact to their request.Reading comprehension is not for everyone.
I want a geodesic dome addition on my house. I want size picrel. I know this is masochism.Question is how would you go about this? I was thinking metal frame with premade adapters at the corners to properly angle the whole thing. Pair that with premade triangle panels in wood frame with glass installed. I think this glass part is where the money will end up.
it has to do with climateactually i live in the southwest and i look into this a lotdue to the extreme weather i faceits either too hotor too cold and windy and snowyout of all the designs i have seen there are 2 that stand out1 the cement dome built in places like texas cathese can be covered with plaster or dirt burriedand they are fully weather proof, run an ac mini split and the thing is perfect in many weather typesand will survive most fires2 is that gay hippie earthshipalthough i have seen many versions of itComment too long.

Hello. I would like to find quality hair clippers to cut my hair off with.I have bought this set a couple of years ago for a great discount, is this hair clipper a good model which should last me years?The hair clipper is a Wahl 09243-2616 and doesn't use a battery
Got my wife a pair of Wahl Senior corded clippers for Christmas when we were still dating. Needed a haircut before Christmas so I let her open that one early... Bitches love practical gifts.Looks like they still sell them on Amazon and they're $92. Buy them and use them forever.

>>2792098>You can’t notice more than a hundred or two Hz on a static display, only when you move your head rapidly. Keep still while watching films, zoomer.Im 42. Anyway, no, I want to be able to move my head as well as the display and not notice that the image consists of alternating full on/full off square wave hundreds or perhaps thousands of times a secondIf I had to guess the frequency I could detect (and yes, waving around simple patterns is a valid method of detection), Id guess I could notice at least 10,000 Hz.Again, I really feel I need to set up a standalone device whose sole purpose is to see what PWM frequencies I can notice are PWM. If anyone wants to suggest what that number might be, Id love to hear it, but waving simple patterns around is a valid use case.
>>2792088Never forget what they took from you
>>2792098>Don’t people still use those Nokia displays in projects?Nokia yes, I use them a lot. They are relatively low current but I meant these. Apparently they can be hard to drive since they require complicated stairstep waveforms to save on pins, so they probably also require a separate driver chip. Ando those Nokias are just SPI. But they draw a few mA and are not suitable for portable stuff.
>>2792104>but waving simple patterns around is a valid use case.I'm just going to point out that this kind of isn't. Why? Because there's no upper limit to what you could detect doing this. Any increase in refresh rate/PWM frequency can just be counteracted with moving the phone faster. You'll see the same thing, at least until you get to rates so high that either the screen is moving by too fast to see, or the turn on/off time of the LED sub pixels starts to become relevant.Realistically, you should just shoot for whatever isn't noticeable in NORMAL operation. I don't have any idea what that's going to be for you personally, but some cursory searching shows certain sensitive people noticing at ~1kHz. Maybe start at like double that. I'm not sure how valid a single LED flashing by itself in space is as a comparison to millions of microscopic elements on a screen is, though.
>>2792119That is not the effect he's complaining about. That's just the poor response time of an LCD panel. OLED is basically as good as a CRT there.Also, for the record, the motion blur was a fair tradeoff in exchange for the increased resolution and a 40" monitor that doesn't require that a steel weldment be added to support my desk.
I want to construct a similar design (an "invisible" chair that makes you look like you sit in the air) and I need the name for that part. It's a thing that would link two metal bars together, allow them to fold, but stop at a 90 degrees angle. How would you call that part? Do you know where I could find it?
