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!
Since we got a gardening thread now it seems only right to get ourselves a mushroom thread.https://blogs.cornell.edu/learning/how-to-grow-mushrooms-a-beginners-guide/https://www.almanac.com/plant/mushroomshttps://northspore.com/pages/mushroom-growing-guidesWhat are you growing?What are you trying to grow? How do you avoid contamination?

Small time first timer here. Is it fine to put my oyster bags in a kitchen cabinet? If I cut the bags open for fruiting, are the items in the cabinet safe? It's a condiment cabinet. I don't really have the space or time to build a growing rack right now. If I want to make a new cake, can I just get a small pinch from the old cake to new substrate and keep it going forever?
>>3008288You can use a large plastic tote, i suggest not putting in the cabinet cuz theyll drop a bunch of spores everywhere, especially so for golden/yellow oysters.Heres some vids to give you ideas on what you can do, im sure theres a bunch of other methods though. But the key things you wanna nail are fresh air exchange(FAE), high humidity and mitigate spores from making a mess.https://www.youtube.com/watch?v=OxXTMlCjKRMhttps://www.youtube.com/watch?v=9OPEqzJ7m5ghttps://www.youtube.com/watch?v=TKE4rErN6ys
>>2995151Have your totem's fruited? Curious how long they took. I've got a bunch of shiitake logs fruiting, but nothing on totems so far.
How do I keep propogating my oyster mushroom cultivation without the fancy liquid culture, sterilized tools and pressure cookers

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.
>>3008723and the fact this new video isn't how they did it from the outset proves their AI is turd AI and they are finally trying to address that
>>3008733So um when are you gonna release your super cool AI(TM) that is totally going to beat 20 years of research founded by billions of dollars and finally prove to the world the heuristic based computing (you know the AI branch that died when neural networks got bigger) is actually the way to go ? I'm legit curious on how you'll react when you'll inevitably get nothing out of it, I legit hoape you don't harm yourself I don't think you are a bad person you just need some help
>>3005837Dude, don't you think if your idea could be done, the mega corporations would have already done it? How the fuck do you think your dumb ass can make a self-replicating arm when nobody else on the planet can do it? You have ZERO artistic ability, your circuit traces show that. You're sloppy. You're short-sighted. You're BULLSHITTING YOURSELF, of all people. Just admit defeat for once, stop wasting your life, and do something productive for yourself and your family. It's OKAY to fail at this. Failure builds strength. Making these threads just pisses people off, because they see how fucking retarded you are and nothing short of you getting a lobotomy will stop this god-forsaken nonsense. Just STOP. You're learning NOTHING. You are INCAPABLE of learning ANYTHING of value, and you're wasting precious time of everyone involved.At first I thought this was an elaborate trolling attempt. My mind wouldn't accept anything else for an answer. But after seeing your insanity over and over again, I understand that you are deeply mentally handicapped. For the love of GOD, just fucking stop, man. At least stay off the internet, you're only bringing negative value to everyone who sees this. Your posting and behavior makes normal people want to enact violence upon you.

Get ready for the influx of poorfags buying ender 3s from thrift stores I bet you feel old now
>>3008896I used to buy them in bulk at microcenter for $100 + free roll of inland PLA a pop and tan an ender 3 pro print farm The mean well power supply alone was worth $20 same with the PLA roll…. I have a few duds, some of the ones with silent drivers the frames came skewed (holes not aligned) so I had brand new Enders ripped apart for parts new in box to keep my farm going After while I got tired of pulling a printer offline hot swapping it for another ender off my service desk and went all prusa mk3s+ but I wouldn’t have been able to do that for “free” without the Enders I think they’re okay but they have a very limited service life before they’re not worth your time. Every minute I was rebuilding an ender 3 was a minute I wasn’t inside solid works or fusion making me money
>>3008896Some of the more stupid shit I’ve done with ender 3 parts was 1: used meanwell psu for a hota d6 to charge drone batteries 2: sold one to a coworker who was working on a dmg Mori machine with its 24v DC system was shot. Yanked it off my ender 3 and we just sheet metal screwed that shit in the cab I think it was a Mori sl25? Think it was the weird one with the Y axis and proprietary tool holders I was a cnc junk guy for awhile lol
>>3000133Why's Ender 3s going to show up at thrift stores suddenly?
>>3000133I envy the discount, I got mine brand new.
>>3008672>He can design anything.I meant cant design anything.He does this a lot, gets something, talks about it a lot like he is something special and does nothing with the shit. Has a a few laser cutters that sit there also in the back of his shop. Wont sell them, wont do anything with them. Along with a shit ton of computers, servers, and networking equipment that he does nothing with. He also has some other random shit like a soft serve ice cream machine like what Dairy Queen uses. He runs a computer repair shop and he doesn't know shit. Yea he can do basic shit such as OS reinstalls and upgrade RAM and Storage. For the longest time he didn't know that some GPUs have a power requirements. He tried to run a 300W PSU on a AMD Radeon RX 580 and could not figure out why the system as fucking up. A guy brought in a workstation that was having issues. My friend said "he did not understand why the guy was using a Nvidia Quadro Graphics Card for CAD". He also thinks that you can put modern Intel i series CPUs into older systems to replace the older i series CPUs (ie: putting a 10th gen i7 into a motherboard that had a 3rd gen CPU in it).>I like how people call them maker spaces>Don’t make shitWe have a "maker space" in the public library. I say it's a craft crap shop. A few 3D Printers, a small laser cutter, vinyl cutter, heat press, button maker, laminator, sewing machine, and a cricut cutter.I thought about starting a maker space in this town but there are too many thieves, crack heads, and retarded ass kids (the ones that will steal, come into businesses to start problems and/or make a scene, etc) and the group of people that think it should be free to use.
Why are so many Americans willing to pay for someone else to mow their lawn?
>>3004022These days my street has a lot of Asians. Vietnamese cut their own grass because they are frugal people. Chinese pay someone to do it because they think its low status to cut your own grass.
>>3004022>not having to mow the lawn is worth more than they money they ask for
>>3004041I guarantee you no one is analyzing the situation that much.
>>3004144I'll never understand going to the gym. Why pay to go to the gym when you could move rocks on your land for free, and in the end you have a cool stone wall/bridge/folly/grotto/whatever.But yeah mowing the land is the easy part, the hard part is hoping the 30 year old riding mower cranks and repairing it when inevitably another part has rusted out but better than buying new trash you can't repair.

Winter Is Coming Anon. Are you ready? The time for Lumberjack Testosterone is upon us.How many cords will you burn? Do you buy or buck? Show us what you are working with: Splitters, Chainsaws, Axes, Mauls, & Saws. What are you cutting? What are you burning? Where & how are you sourcing? What are you burning in; make, model, year?
>>3008958firewood always gets expensive in the fall/winter. its a seasonal commodity didnt you ever read the fable of the any and the grasshopper?
>>3008963nah, 400 a cord is unheard of unless you are a restaurant in the middle of NYC.sub 300 is max for dry in middle of the winter.wait a minute, you sell firewood don't you, moshe?
>>3008977i havent cut wood to sell since high school circa 2003. was selling oak for 175 and fir at 125 then which if corrected for infinity m2 printing since would be way more than 400 nowand i quickly decided it wasnt worth doing it back then either git gud grasshopper
it is done.started at 10:00 finished at 18:00 today. two piles to the back (left of frame) are 85% seasoned. they've been sitting for 18-14 months, but were only bucked last month. the two giant piles up front (right of frame) are less than 2 months old. still not sure how many proper cords there are. I will get it stacked later this week and finally have an accurate measurement. but if i had to guess i would say 1 cord seasoned, 1.5 cord green. there is wood behind the seasoned piles that dosent show well in the photo and we have about 1/4 cord stacked on a rack by the back door.glad its done.
>>3008958and for 700 you can get yourself a chainsaw that will give you a dozen or more cord every winter for years.There is always deadfall to burn, ask a local farmer there will absolutely be a few who would be happy for someone to clear some trees away from fence lines or out of sloughs in their fields.
A breaker bar is a breaker bar, right?ITT: Shit tier tools
>>3008959Stealing this idea.
>>3008955That doesn't change that the bolt should go before the tool.
>>3008959That's really nice

>>3008985Dozer, combine, semi, tractor and a dozen+ pieces of equipment.We've got it all on the farm.You don't snipe a flex handle and then jump on it, you put even pressure, if you're not fucking your tool like a jackass moron the flex handle doesn't break, the bolt does.

>>3008868>jgb37-520Looks like it's probably a quadrature encoder. Write some code to read a quadrature encoder, or just steal an existing rotary encoder library, and confirm that works by itself. By spinning the motor shaft manually and reading the rotation back via USB serial or something like that. The encoder phase A and B pins might need pullup resistors enabled.
>>3008870Thanks for the support.Yeah, it seems they need the resistor.I have never used the encoder, does it need both phases?
>>3008875You need both phases to tell direction and ensure accuracy. A single one may give you a speed estimate, but no direction indication and the position estimate will drift easily.Quadrature encoders are simple devices with lots of example code available. It's worth learning how they work and you should be able to find robust implementations easily.

2 questions1) what is the best type of brush to clean stainless steel?2) Whats the best way to de-rust steel/metal? If I just soak them in vinegar, it seems to work but leaves a bit liquid film on the part that still has some rust on it. Ive heard electrosys(sp), but it seems kinda scary and hard to setup.
>>3008978>Whats the best way to de-rust steel/metal?Enormous question. Really depends what your specific situation is. Sandblasting works great but probably isn't practical.What rust removing chemicals are available in hardware stores near you?

>>3008928The idea of shredding waste into new filament doesn’t really work, at least with PLA, because each time it remelts it becomes less viscous and more prone to leaking out your nozzle. You have to mix it with a lot of fresh PLA pellets. If you’re already making your own PLA filament from pellets then it’s probably worth getting a grinder, but only print farms will be operating at enough scale for that.Maybe pellet extruders have less of a problem with remelting, they’d also not require the labour for handling the spools, which seems like it would be significant unless you’re spooling 10kg rolls.I’ve thought of remelting waste to make blocks of solid plastic, they make good knife scales, I guess?>>3008951Packing isn’t a stupid idea, maybe you can melt the waste into something like a cotton candy machine. If I recall, NightHawkInLight needed to spin PLA fibres for a sky cooling fabric, which was difficult because PLA doesn’t like forming thin strings. I bet PETG would be easier.With a pressure pot you could probably also create a plastic foam.
>>3008969I use PETG exclusively, i did wonder how well it'd be on a second go-through if it was reshaped into filament
>>3008972Have you seen how some people print out filament in a spiral on the bed in order to print with it? Usually that’s for the purpose of using an AMS to get multi colour coextruded filament, but you could just do this like 5 times recursively to see if it prints any differently.
I had finally gotten fed up with trying to level the bed on my K2, realizing that the tacoing was never going to get better, so I went with the only options i could think of and literally sanded down straight down the middle of the bed, especially at the edges. Turns out that actually was the best way to offset the bow in the middle without getting a new bed. I used some kaplan tape on the sides of the bed sheet to finish leveling it out, but i was finally able to get a deviation of around 0.3 max
>>3008926Well, the lid started to separate between the layers, so printed a plain PLA replacement.Then the seam the lid latches against broke off the remaining tri colour part, so now its all standard PLA as god intended.

Needed to modify a w1099 temperature+humidity control module. By default its humidity regulation would vent all the hot air I’m building up and prevent it from getting up to temperature, so I had to ensure the humidity controlled load would only activate when the heater was off. Next, because this is a 12V module and I want to run it at 24V, I had to add a 12V regulator, linear because I don’t have any 24V capable miniature buck converters lying about. Then that was dissipating too much power, so I swapped the relays for MOSFETs. I was going to have to add an additional BJT to invert the signal going to the FET gate, until I realised the 5V MCU outputs were capable of driving a logic-level power FET (IRLZ44N) by themselves. So I desoldered the onboard BJTs and ran a jumper wire to the FET gates. Hopefully this setup should work more reliably than the original relay design, I’m only switching 2A@24V, but there’s going to be a bit of heat nearby.I might need to blob something in to mitigate vibration, but it feels pretty rigid.
I need some BNC to RCA adapters to use a PVM I picked up with more devices. Is stuff from Hosa (hosatech.com) worth a damn or is it just rebranded Chinese trash like everyone else's shit?
I've decided I want to spend more time learning the actual theory/math behind this shit. I have tinkered and got things to work on my breadboard, but I don't like having such a big knowledge gap. For people who know their shit (even on a smaller scale like just small circuit stuff), how did you best learn it?
>>3008956University courses that recorded on YT, edx and mit. And also free pdf uni textbooks from web. That's how I did it
>>3008956Once you get ohm’s law, KCL/KVL, complex impedences, and the common components (passives, transistors, op-amps), you should have enough of an intuition to get by self-taught. When you need to learn how to make a good feedback loop, you look into control theory. When you need to do some dac or adc work, you look into nyquist sampling theory. When you need to handle high frequencies over significant distances, you look into transmission lines. That’s how I did it, having learnt the basics from a university course.
I've got a low spot in this concrete pad that collects water after it rains and inundates the steel post. What to do for drainage?
>>3008863Let sleeping dogs lie. Get a squeegee.
>>3008863If the pad is thick you could cut a shallow V-groove to where you want it drained. The Bottom of the V groove needs to slope away the whole distance.You also need to study the contour to make sure you’ve got the V-groove in the right place.There are these guys that will drill a hole and pump up the corner with either concrete or PU foam if you’ve got monies.Another thing you should independently do is get some zinc sheet and put it underneath that post. To act as galvanic corrosion protection. You can get it as flashing, or whis strip you nail to the top of your roof to alow the zinc to kill plant material if you have a mouldy/mossy roof.
>>3008863Mortar concrete on top to make it slightly concave.Otherwise you're going to chisel and drill
I'd just grout around the column itself to give it a slight slope and keep the water out from under it, then hit it with your leaf blower immediately after a rain if it bothers you.
>>3008863by the looks of it, you have a slight ledge on the edge of the slabget a concrete grinder, one of those with a stone and be miserable one weekend to shave it down
