I bought a new whiteboard, it is one of the best choices i made this year, i wrote a lot of things in it and honestly it is better than any form of acquiring knowledge.To me the difference from other formats is that a board is ephemeral, the information in it cannot be looked at later making it a good way to prioritize the things that are really important.What are your suggestions on what i can do with it?
>>2980841Next time write your post you are going to put on 4chan on your whiteboard instead and then immediately erase it.
>>2980841How ate those post-its held on there? Is it magnetic too?
>>2980856yeah
>>2980841>honestly it is better than any form of acquiring knowledge.Organizing knowledge. You have to have it before you can put it up on the board.
How problematic is this gas pipe in my kitchen? A tile setter ripped off the wall handle and removed the surface layer.

It's fine. That's just external lacquer. Sand and paint the area.
>>2980548wtf is that willy wonka hat spacer? the only thing you need is to replace the support
solid state wind generators run on a similar setup that flowers use to signal to bees they want to be pollinated, voltage difference between pistil to roots improves pollen stick, but i digress, plants seem to all grow to roughly the same height not sure what the mechanism is for this but it seems competitive, plant height and plant width appear to have a ratio, big trunk supports tall tree small trunk supports short tree. so the idea is to create artificial competition to accelerate above ground growth, by shoveing a wood dowel into the ground and wind a thick gauge conductive wire around the wood higher than the adjacent plants by a few inches pulling the copper wire up every couple weeks to maintain its competitive dominance. bonus points for legume nitrogen fixing bacteria. tldr: fake plant conductivity to fool fungus into over lending for accelerated growth.the questions what metals wont screw with the plants? support structure has to move/hold water to mimic organics changing voltage? what mechanism enforce/create crown shyness?
>>2980574>roughly the same height not sure what the mechanism is for this but it seems competitiveyou mean reactive, if you mow dandelions they will grow back short.you need a control group and a group with only the stick (I'd put forth the stick being south of the plant in northern hemisphere is more conducive to competitive growth than voltage)

what's up with the shed roofs?
>>2979914Do metal roofs actually reflect IR pretty decently or is it a meme?>>2979830L shaped house. Gabled on the left and right of the _, but hipped on the top of the I, which is south-facing. Literally defeats the purpose of how gable vents function, by drawing cooler air from the non-sun facing gables and exhausting hot attic air from the one facing the sun. I also have ridgevents, but the soffit vents are only along the I part of the house so the right side of the _ got noticeably hotter than the rest of the house until I added a shit ton of extra insulation.The hip is also where the fucking attic ladder is, so the slant significantly reduces attic storage space. Too expensive and annoying to fix because it's also where the electrical mast is attached.
>>2979830Has anyone ever seen a butterfly style roof in the wild? Seems like a shit design...
>>2980512I don't think it actually exists. Seems like a really stupid configuration as far as shedding water is concerned, while also being ugly as hell.
>>2980429>Do metal roofs actually reflect IR pretty decently or is it a meme?Depends what color the roof is. Having a metal roof painted black will absorb more IR than having a metal roof painted white. But that kind of works the same way with most roofs.>>2980512I seem to recall some airport using this design. I do remember seeing it on a house we did a teardown for years ago. Thing was straight out of the 60s, with a stone grotto and a completely fake grass lawn. I remember it because as we were surveying it my crewman said the only way it could get any better was if it had pink flamingos. Then we got to the back yard. Needless to say years of exposure to the elements does take the pink out of the plastic flamingo.>>2980666It's not too bad, in theory, by concentrating the rainwater into a channel you can control where that water exits off the roof and put a single big downspout or some other water feature below it, plus the more water that the channel carries the more likely that it will hit self-cleaning velocities like a sewer with only minimal pitch. The downside of course is that it needs extra waterproofing along the trough and that you'd probably still need to clean it periodically.
>>2980791I've only ever seen them on carports out here... until a few years ago when an apartment complex in the area went up that used them. But wait, it goes worse. They aren't actually butterflys. They have a false butterfly facade that is only a few feet thick and then a normal flat roof. So, its only reason to exist is to make the building look ugly.

I have an old Lincoln Electric SP100 that works fine but I'd like to get back into TIG. Would a multiprocess welder be an upgrade or will I end up with a shittier MIG machine? I'm looking at the Omnipro 220 or the Power MIG 215. Light fab/hobby use.I'd get a dedicated TIG box but I'm pressed for space.
I can't get the hang of tig. All my pieces have suckback.
>>2980733The omnipro 220 is a kickass little mig and stick machine. I have not tried mine for tig yet as I have a dedicated ac/dc Hobart tig machine. But you should not be disappointed in its mig/stick abilities as far as I'm concerned.
Is there any practical uses for used cooking oil and grease?It's flammable but idk how to use that to my advantage .
>>2976769The most common and useful thing is to use it as a basic lubricant. It's not motor oil, so it won't withstand high heat, but for everyday uses it's fine. If you really are homeless then you might use it for lubricating your bike chain, zippers, locks, and folding knives. You may also need it for personal comfort such as treating dry skin, sun burn, or bed-rash caused by unsanitary conditions.
>>2978718No.Cooking oils go rancid and start to smell and turn into this gel and get gummy after a while.Some oils, like castor, the going-rancid effect is less pronounced. Coconut oil is similarly more stable. I had an old lip balm with olive oil in it, opened it, and it smelled disgusting. Flaxseed oil is the worst, so much so that linseed oil is used as a furniture finish.

On my block the water pressure is shit so we had to install a home booster pump for water. Has been working fine the last 5 years but today this shit doesn’t work anymore when i turn on this shit I can see spin the bolt in the center but this shit don't make their job so i have no water.And yes i already tried to purge it by turning to the left the inner bol using a flat screwdriver, i even used vinegar to clean the inside but this shit just looks like it lost pressure or something because even the noise is not the same, it hears like weak, even when i was checking for any obstruction i noticed that the end part where it goes to my water deposit the pressure is weak(i guess it should be like the squird of a japanese porn actress, right?)So any idea how can i fix this? I have no money for a new booster pump right now.
>>2980686You need to get that sort, man. Not just for your pipes; your kidneys are filtering that shit.

>>2980631>bearings are probably fuckedIt would make more noise if the bearings were bad>>2980642>Pic related the box, you tell me what i should remplace(i know how to soldering with iron pen btw)Large cilinder thing on bottom left, it should have some writings (should be something around 2uF or 3uF) and you can find it at an electrical material supplier/appliance repair shop/scrapyardAlso you shouldn't need to solder because the white plastic things where the wires attach to look like spring contacts, they should open if you push on themI've checked on similar circulator pumps and they should make between 1000 to 2000 rpms, so from your video is probably too slow
Op here. Thanks a lot to everybody for the help. I bought a new cheap home booster. Anyway I will try the capacitor thing with the old one because im interested in know how to fix stuff. I tested the old capacitor using a multimeter and seems like is a bit ruined because sometimes i got lecture and other times not, i thought it was an issue due the wires being exposed to the calcium of the water so i cut the plastic to get a new clean copper and nope my multimeter will show me a lecture some times and others times not(i don't think it was an error of my multimeter because i tested it using dead AA bateries(i always got a '1') and working AA bateries (i got numbers like '56.5'). All these tests were made with the multimeter at 200k ohm just like i saw on a youtube video.
>>2980767>All these tests were made with the multimeter at 200k ohm just like i saw on a youtube video.The capacitor will be charged by the multimeter the first time you attach it, giving a reading, but, once it's charged it wont and you'll have to short the capacitor leads or connect the multimeter leads in reverse to get another readingUsing a multimeter in the ohm range can be useful to detect a really bad capacitor, but usually those in small electric motors slowly lose their capacity instead of failing completely and you can't detect that unless your multimeter has capacity measurement

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.

i just finished designing the digital logic of a tile-based graphics circuit inspired by the snesit's got pretty much all of the features of the snes, except for mode 7, the high-res modes, and per-tile background offset modes. it's an 8-bit circuit with output resolution is 128x128 pixels.pic related is a portion of the background circuit
Alright. While working on tables I realized I was quite careless on whenever some functions return nils or empty values, which is not the same thing. I also learned about some functions that return more values than it is documented.So I spent time revisiting all the tests and fixing all the functions. I also realized that quite a lot of basic functions were not correctly behaving in some edge cases so I worked on fixing the basics. It's a shame how things are, 80% of progress is done 20% of time, and the rest is just ironing out all the bugs and incompatibilities. And I still haven't even begun to use fuzzing to really reach for that 100%.Anyway, now I have all the more basic functions behaving correctly(except trace maybe) and finally coroutines support. The most painful was probably tonum(str, flags). Pico-8 uses like 6 different ways of parsing numbers depending on context and configuration and it took a lot of experimenting to reverse engineer all of them. But I think I got them all. And I also went back to fix number to decimal string conversion, it now should be 100% equivalent.>>2974692Pretty cool. Are you using any chips for that or just designing it from basic gates? Do you plan to realize it in real hardware?
Holy shit these table related functions are easily the biggest pain in the ass so far. I don't even try to test every possible edgecase with metatables, but the code should take them into an account. I will surely have to revisit all of these functions with more pedantic tests if I want to 100% imitate their behavior. I also discovered yet another set of undocumented functions, but these will have to wait until I finish what is already on my plate.Also this project makes me learn a lot of nuances of Lua that I never knew about, despite knowing this language for so many years. I feel like there is nothing more that could surprise me at this point.
Need advice on hanging a bathroom cabinet. The wall is a plastered brick wall but there is a big metal sheet in it. I can only drill half an inch into the wall before hitting the metal sheet and i am not allowed to drill into it so i cannot use wall plugs. The cabinet also has these small screws all around the outside edge on the back holding the back panel in place so it wont sit flush against the wall if i tried to glue it somehow.It weighs 15 pounds empty and will weigh around 20 full. How would you mount this above a sink.
What's behind the metal sheet? Are you renting or are you just too pussy to drill through that bitch?
>>2980462There is a service cupboard with pipes and electricals and i am renting. I had hoped the metal sheet was further into the wall when i started drilling.
Find support in ceiling. Hang using wire. Use a little double sided mounting tape to keep it against wall, or a few of your half inch screws

>>2974858Sure, I used to do this stuff and still would if it would not require me to move to a city of more than 20k people or travel. Your picrel is not particularly high quality, decent but exploiting that no one is going to look all that closely so perfect is overkill. Might just be parallax, age and filth, hard to say from just this photo. >>2974919>cardboard templatesNah, you just scribe it right onto your work piece, takes 5 seconds. Cut the outside curve with your coping saw, remove the bulk of the profile with chisels, fine tune with a couple scrapers ground to the profile, cut the inside curve, clean and fine tune the inside with your knife and nail it up. Takes about 15 minutes to do it to the quality of OP pic, 30 minutes for perfection. If you had lots to do you might make a scraper shave or two to speed the work. Learning to do something like this is easier than learning to get good at coping, you don't need perfection here and small variations will never been noticed, there won't be a gap emphasizing the flaws. Good luck getting your 3d printed molding to look like stained wood, even if you manage it, it won't last, the wood will darken, the grain will either become more pronounced or get lost as to wood darkens and your faux finished 3d printed molding will stare at you from across the room.

nail plate appreciation thread. not recommended uses for nail plates
>>2978199I believe thats the difference between rafters and trusses. Rafters are built on site by the carpenter, and typically are just nailed together, trusses are engineered in a factory and are stamped together with those plates. It lowers the number of inside walls that bear the weight of the roof and snow on top of it.
