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!
>DIY youtuber filming & posting their project>they use tinkercadcan someone please help me understand why half of DIY engineering youtubers' go-to 3d modeling program is an imprecise, enshittified mess made for kids?
>>2972433Fun fact: you can vibecode scad
CADCHADSI just finished downloading Solidworks 25 SP5, what am I in for? Any sites or YouTube channels to check out? Im going in with 0 experience and no real purpose/reason to learn. Just wanted something new learn. Maybe take the CSWA in a year? Model some stuff and shit it out on my resin 3d printer?
>>2973127SW has decent built-in tutorials, check them first
>>2959233I forget the name but dassault used to have a free 2d cad program I used all the time for actual work making drawings for steel and pipe fabrication. Idk if they still have it but no student email was necessary
>>2959261>>2960917My dad was educated and licensed as an architect but ended up spending most of his 40 year career doing movie/TV set design and only just retired last year. He used both Sketchup and VectorWorks (AutoCAD alternative that's popular in his industry) heavily, Sketchup for preliminary design work and then VectorWorks to do the actual working drawings. >>2960968I really need to figure out how to do this in Fusion. I know how to make it so that features will stay the same dimension or the same relative placement (parallel, concentric, etc.) but not how to do what you're describing where it's a ratio. I'm working with a pretty complex sketch that'll be plasma cut right now and resizing it manually is gonna be a bitch.
Need help/advice.Symptoms were:-loss of compression on pistons 2 and 3-gurgling sound heard inside cabin (sounded like air bubbles in the water running through the heater matrix)-some white smoke exiting the tail pipe. Not a lot of itI've removed the engine head, convinced that the gasket was burnt. It seems fine (see second pic). Now, I have to buy a new gasket (I was counting on this) but, because the old one doesn't seem burnt, I don't know the origin of the problem. So I could end up reassembling the entire thing, just to find out the problem is still there. Help
>>2971131>I can't remove the block and I'm not going to remove the pistons.I don't think a set of pistons and a 30 over is really that expensive.you can hoist the motor out with a tree it's not a big deal.
>>2972700I've been cleaning the engine block surface.I used 180 grit and did it by hand. Turns out I created some highs and lows and I'm gonna have to find some sort of lap to remove those.>can you tell if one of the pistons isn't coming up as high as the others?I'll try that when I finish cleaning the surface. I've put a little bit of grease around the pistons so that abrasive won't fall on the segments, so I don't want to move them right now.>>2972702you can hoist the motor out with a tree it's not a big deal.Kek. I live in a city. Getting the car under a tree is not so easy
>>2973146>lapping a blockNot going to work. You are nearing the sunk cost limit here, anon. If you aren't willing to yank and plane it, you just wasting your time. People will haul it away for nothing or just part it out.
>>2973147>Not going to workWhy not? People make things flat by hand, either with an abrasive or a scraper
>>2973152>thingsThose things don't include something trying to contain the force of a gasoline explosion. >muh valves are lappedThe force of said explosion works in the favor as it compresses the valve in the port. If you try to lap the block, it works opposite.

>>2973139If your car switches off when you open the door, it seems like you already have your cutout switch. You might want to put in a performance alternator though.
>>2973135>look at the bot, posting away
>>2973125>you use some special screws to drill in to metal, not sure what they are called in english, as I'm also ESL.yeah, I know. there is a series of videos that teach how to install drywall so I got that part covered. but I don't want to have to deal with plaster, or even with the drywall itself...
>>2973145Maybe leave the plaster and just go over with some 1/4" sheetrock. Then put some panelling over the drywall. I also hate the bullshit with drywall. >hang it>joint it>paint it
>going into loft to see if I need to lay boards down>discover boards beneath the insulation, things looking good>Discover thisThis is what I think it is isn't it? Hard, claylike, slightly fibre like along the edges. House was built in 1960s, old forced air heating system previously with all the vents now sealed up.I can't afford this shit...
I just think the color is cool
Yeah I have several Ryobi tools that were given to me. They surprised me ngl, especially the angle grinder.Perfectly fine normie tier around the house brand
>>2972950Green is what you associate with faggy eco shit, it doesn't belong on power tools, makes them look cheap.Now orange and grey I can get behind, looks industrial and tough.
>>2972950Flashlights break. Batteries overheat easily. Circular saw has almost no useful power. Air nailer has safety to disable shot after 3 seconds. Router shuts off from normal resistance to bit. Drills are fine and get the job done. They work
I finally stepped into the battery tool game with one of the $199 Ryobi kits Home Depot had for black Friday. I really can't complain. For hobbyist shit they're great, the impact driver has helped already with a couple fixes on vehicles, the drill seems perfectly adequate, and the tiny ass circular saw was more comfortable that my big corded one for cutting 3/4" cedar. Haven't really had a use for the oscillating tool or reciprocating saw yet, and I've got a ton of flashlights already, but they seem solid enough.

>>2973098>block network connectionsThat only makes me want it less. Looking at posts about LAN mode seem like it makes Bambu printers a whole endeavor to setup local software tooling which defeats the purpose of the unbox and print shit without tinkering with the actual printer itself.So the real value is in buying into their walled garden up in the cloud???I guess this brand isn't what I thought it was.Also, I've noticed 3D printing subreddits are full of bots. Not proverbial bots like, "hurr durr I don't what you're saying therefore you must be bot-brained". It's literal GPT bots dumping obvious prompted responses. And there also seems to be lots of sketchy activity like random posts will get bombed with militantly aggro replies.
>>2973104>so, I've noticed 3D printing subreddits are full of botsIf you shill your model via a makerworld link you get points that you can exchange for giftcards in order to buy printers.So, it's almost all just people trying to farm these points so they can get $5 giftcards.
>>2973091>>2973098Just don't. I can and do forget ASA rolls for months and they do fine when thrown in for a quickie. Meanwhile PETG needs more care than PET-CF, while being fuck all in every comparison. It's really an abomination of filament.>>2973104>Always has beenThere's a whole joke about reddit being mostly bots anyway, but 3dprinting is also one of the more infuriating ones because users brought up the issue of promotion spam several times and mods just continued to watch regular people leaving for dedicated forums.
Been thinking about buying a used 3D printer. Are there any brands i should look out for? Skimming the posts i see people mention bambu labs having some kind of walled garden thing. I take it I should avoid those.
>>2973140On the contrary: you should get one. They're far from perfect, but they're very plug and play. A lot of annoyances with lesser printers are solved by the Apple approach to user experience, infantilization, so the learning curve is way lower.
So, together with a friend, we have decided to make our own console for fun and giggles. This surely is an undertaking but this is an idea we were considering for a long time and as we got more and more experienced with circuits, embedded programming, 3d printing and stuff like that, I feel like it would be finally in our reach.I never really looked at other people's similar projects, I have no idea what I'm doing honestly, but I can write code and I can use google so I think we will figure it out and get there eventually.I will post our progress in this thread.

>>2967212>Hurr we e learned a lot about electronics and circuits Seriously, kill yourself
>>2966575I'm back from Christmas break and finished map support. That's the last graphics api function minus the linet which I'm sure is only used by pseudo-3D games. Getting that one work perfectly the same as in PICO-8 will probably be quite tricky, so I will save it for latter.Now it's time to implement all the random miscellaneous functions and registers that I have not takes into account so far. Once that done I should be able to just run pretty much any existing 2D PICO-8 game.
>>2938514>embassypretty cool stuff. will try when i work with a microcontroller next.
Table related functions WIPThese ones are quite tricky because most of them interact with metamethods in suprising ways.>>2970457Good luck

Worst DIY accident you've had or seen?

>>2972096Foreign invaders is what I call them.
>>2972879My great grandfather got run over by a log in a log flume. Not an amusement park ride, an actual log flume. Mangled him. Broke his back, his neck, both arms, crushed his pelvis, broke both femurs, knocked out a good chunk of his teeth, multiple fracturs in his face. He was fucking miles from the nearest doctor and hundreds of miles from the nearest hospital. He was in a coma from the start and it was lucky he didn't drown. His co-workers made a litter out of what they had at hand and carried him to town between two mules. They thought he would die before them even got him to town and the doctor. He didn't. The doctor patched him up and said he would need to go to a hospital for real care and that he was unlikely to survive to the trip. They put him on a train with his wife and she cared for him until they got him to a hospital days later. He was in a coma for months afterwards and spent over 2 years in the hospital. The thing that saved him was he didn't develop an infection. This was before the discovery of penicillin so infection was the number one killer for people that were injured.He was of course never the same. No brain damage that anyone could tell but years on his back turned him into a beanpole. Dude was a fucking lumberjack back when they did everything with two man saws and axes. He was over 6 feet tall before the accident and weighed just over 120 pounds when he was released. Years of rehabilitation followed. His legs were mostly for decoration after that. While he could feel and move them, the pelvis injury meant they couldn't support his weight and he had very little range of motion at the hip. He spent many years in a wheel chair until he taught himself to walk again by using crutches. Sitting was not comfortable for him so he basically used the crutches like legs so he wouldn't be in a chair. He lived into his early 80s. I think he was in his mid-20s when he had the injury.

Is it better to buy the trashiest used mobile home I can find, buy a shipping container and DIY, or buy a prefab "tiny home", cuckshed, etc.? I want to do the bare minimum, the only real requirement is having a roof over my head.
>>2973041>>2973029Thanks, I live in the UK and I'm a DIYlet, I literally just cant afford to buy a house so I bought land and am going to watch some carpentry youtube videos LOLdesu I was thinking of a dome just because aside from looking cool, they seem sturdy and straightforward to build
>>2970684>Cardboard boxinteresting option. some youtuber made a bunch of stuff from cardboard and used a DIY coating to make it waterproof:https://www.youtube.com/watch?v=45JhacvmXV8guy also found a cheap and easy way to make aircrete: https://www.youtube.com/watch?v=z4_GxPHwqkAand many other things for passive cooling/heating>Electricity? Use batteries or solar.you could use solar panels as roofing too, or at least to cover some cheap roofing.
>>2973093Domes are cool but they are difficult to build with standard materials and require a lot of cutting things to size. They produce a bunch of waste if you aren't using a kit so either way they are an expensive option for the amount of space you get. They are very strong though.If you want to DIY it you need to see what is the preferred building method for your area. I don't know about the UK but in the USA it is generally what is called stick or platform framing with wood. Wood is the cheapest option here, is readily available, easy to work with, requires minimal tools, and very little skill. As I mentioned, it is so common they don't even require plans for smaller buildings. That is not true everywhere. Especially if weather is taken into account.

>>2973101>>2973030>>2973004But I am not sure about ordering these as I will use my money here. At least with the AP-1000, alexshroyer.com already shows you can use it for this and there is little uncertainty from my own ignorance of various electromagnetic details to account for. But with these other current transformers I am afraid there is a detail I could miss that makes them less practical/impractical for my purposes. I also wonder if I might be overstating the tediousness/difficulty of simply making my own 1:500 or 1:1000 current transformers with copper wires and a toroid <0.5".Another alternative I might not have explored is simply scavenging and see if I can find a small 1:500 or 1:1000 current transformer in some old appliance or trash or something.Thoughts anon?(2/2)
>>2973101>>2973102Nevermind fuck all this overthinking.I pressed the button.
>>2973105Actually nevermind again perhaps I should overthink. I pressed the button, but I haven't pressed the next button... because I remembered that China existed.These Chinese current transformers are significantly cheaper, and they are small.Should I use these instead perhaps?Or is there a detail I am missing? They have 1:1000 and 1:2000https://www.aliexpress.us/item/3256809278362452.htmlthere is alsohttps://www.aliexpress.us/item/3256808882683584.htmlhttps://www.aliexpress.us/item/3256810306817408.htmlhttps://www.aliexpress.us/item/3256810311795336.htmlhttps://www.aliexpress.us/item/3256810307013978.htmlBut I have little certainty with any of these current transformers that I am actually getting what I am supposed to try and get for these purposes...
>Digikey cart sitting with components in it for 10 days now>just know that as soon as I place the order I'll realise I've forgotten somethingAre there any US component suppliers with free delivery? It makes it so much more high stakes when it's a 8 USD delivery fee every time
>>2973101There is a middle-ground to 1000 turns on a pickup or 1000 turns on a transformer: putting 33 turns on a conventional pickup and another 33 turns on a toroidal-core (current) transformer.Chinese (current) transformers are also an option. I’m not too sure when a current-transformer topology will and won’t be suitable, it’s all magnetic so it’s probably not a big deal but I’d do some testing either way. You will want thicker wire though.
In Texas, auto parts stores and scrap yards pay $15 for each stolen car battery. Plus the scrap yards will buy the cables. Thieves bust the drivers window with a spark plug, pop the hood, then cut out the cables with bolt cutters. My car has a factory cable with multiple wires and costs $279-. My neighbors and I are struggling to stop this in our Houston area. Any suggestions are appreciated.
>>2968568Move to a better area. If a criminal wants to get into your shit and take your shit, they're going to find a way to do it.
>>2968568Hide battery. Leave original battery compartment empty with two dummy chopped of cables hanging there.
>>2968568park your car in a compound. Have cameras on the compound and an alarm wired fence. Needs to be anti-human fence not a livestock or deer fence.

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.
>>2971967How come you ponder whenever breadboarding your project is a timesaver or not while wasting your time on drawing shit like this in ms paint
>>2972715I drew the schematic in photoshop with pencil tool and that same schematic I plan to print onto transfer paper and laminate onto copper and etch the copper board to make the circuit from that drawing then. So the drawing is not a waste of time it is literally the first step of a diy circuit for the motor controller. It's not a wasted step or an extra step or a skippable step. It's needed 100% so zero waste of time at all.
Ok so I realized I don't have to feed in 8v+ from an external wire when I can just pull it from a neighboring pin on the chip that has 8v+ already fed to it from one of the big 8v+ copper traces attached to one of the big 8v+ pads on the underside that connect directly to one of the side pins. That side pin can then be routed to any 8v+ requiring pins if I can find a path for this routing - which I did find. So that is one less external wire input needed - bringing total external input wires needed to 3 instead of 4 as far as the 30ga wires I need to attach. So now all I need for 30ga wire attachments are 5v+ from arduino, GND from arduino, and PWM from arduino. This saves work and simplifies the wiring so its a great improvement.Oh and I also did the same thing for the 8v- feed, pulling it from a local pad rather than a external wire feed for that.
>>2972920Also, I have separated out the PCB traces themselves and made them black instead of blue for printing them onto the PCB transfer paper and laminating this onto the blank Pyralux flex PCBs for etching them. I also mirrored it since it prints and laminates backwards onto the PCB.
>>2972922>Hand drawing instead of using the rounded rectangle toolRetard
>3x the price of their competitor brands>specialise in powered toolsI don't get it, surely they can't be that good?
>>2971988Fein and Bosch worked together to design and standardize on an oscillating blade standard, and may have worked on dome other mounting standards as well. Fein also manufactures the oscillating tool Festool sells. Fein mostly decided to focus on metalworking, and removed themselves from the woodworking market, other than a cordless jigsaw and basic drills and the oscillating tools and vacuums. Fein may still be making motors and components for Trumpf and Draco.
>>2961078I've used this at a workplace a few times. It's just as full of pot metal and plastic as any other brand. Not anything special or extra accurate.
I used to work for an epoxy flooring company that mixed sand into the epoxy resin. Festool were the only paint mixers that wouldn’t die within a few months, and usually lasted a couple of years.
>>2961078Best friend is a sales manager for Hilti (even more expensive than Festool, 600€ for a basic drill).These brands don't give a fuck about diy, their market are the pros.Their tools are reliable workhorse that can be serviced for years if not decades.Hilti has an asbestos rated service shop so you can actually repair a tool that has been used on asbestos, no other brand do that.The biggest threat to the model is now some artisans buy Lidl shit and treat them as disposables.Said friend told me that for woodworking and painting, Festool is usually the best but for other works, not so much.True to that, the painter and the guy who changed windows both used Festools.
>>2972481>the painterI thought their big brand was Wagner.
