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!

>>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.
>>2792051>Thanks. Sometimes i wonder if those PC GPU cards have more power than the processors nowadays, lol.i think a lot of them do, but it's a different sort of compute power. my understanding is that gpus are designed effectively as matrix calculators. so the circuitry is optimized for i guess linear algebra or vector calculus or fucking whatever, as this is important for graphics. turns out it's also important for number crunching in data centers and artificial intelligence, or as i have started to call it, advanced interpolation, but that's a copy pasta for another time. server side and shit they don't do graphics and don't have video output of any sort, they just crunch numbers. gpu seems to be a historical anachronism kept around just because. fucking nerds.>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.dude that's fucking nuts. every time you print something it's just sitting there, quietly judging you.
>>2792147thank you.i tried to run software serial on other pins and it works fine now.just a thought: if i want to use hw serial on pins D0 and D1, can i just remove the CH340 chip? i can still program the arduino via icsp using another one as isp, correct?
>>2792217Yeah desoldering it would work. Though at that point you might as well be using an Arduino Mini instead. Bootloaders were a mistake.

Use this thread to ask questions you think don't require a thread of their own.The old thread no longer bumps: >>2785345If you didn't get a response in the old thread, feel free to ask again here.
>>2792028yeah its fucking terrible. i would NEVER pay retail price for one of these.like it says its bear rated, but only if you add padlocks. fuck that.wheels are nice, they have bearings, and ss mounts. solid handle. just bad finishing.worst part is they made it thick and small inside in purpose. for its asking price, they could have made a half in thick cooler with aerogel as an insulant. i looked at those handles, they are riveted in. straight up planned obsolescence.its nicer than my current cooler, so im not gonna bitch anymore.
Can anyone recommend a "decent" compact/keychain-sized multitool? I fully understand that they do not perform as well as real, proper tools. I even understand that they do not perform as well as conventional full-sized multitools (like a Leatherman, the Swiss Army Knife, and their countless imitations).I only have the following criteria:>needs to be able to cut at least soft/thin plastic>able to open bottles>reasonably priced>can comfortably hang off a keychain>as few moving parts as possibleThings I do not strongly care for (ie. if it doesn't have these features, I wouldn't be sad about it):>TSA approval>screwdrivers>pliers>wrenches
>>2792127I quite like the swisscard, which goes in your wallet instead. You get scissors, a little knife, and a file. Otherwise, I'd honestly just look for a blade holder with a bottle opener on one end, you're not going to get much more compact than that, this one is like 5 bucks and probably cheaper if you order it from china.
I cleared out my storage unit and now I'm left with a cylinder lock without any use. How can I reuse this thing?
>>2792127Gerber Dime if you want pliers, or the Leatherman Micra if you want scissors.
Every farmer needs a real hoe.Sure, there's plenty of mass production brands out there at the stores.Those work OK if you're dainty with them.But does anyone know where one can get heirloom quality hoes?Hoes that can take a real man working the dirt with them
>>2791932Every man who knows how to hoe keeps his hoe properly sharpened, and avoids contact with rocks or even dirt whenever possible.
>>2791934>and avoids contact with rocks or even dirt whenever possible.i too keep my yard tools as wall hanger showpiece
>>2791932300? Dude, that's one row out of at least 40. I'm not talking about planting, I'm talking about weeding once they've been established in the block. And there are at least 20 blocks.
>>2790297Make one if want that but that's like caring about heirloom quality bog rolls. >>2791926> last five minutes or so of lunch sharpening up Takes a few seconds with my flap disc on a cordless grinder. I hit hoes, shovels, pick axes, cane knives, machetes, and anything else appropriate early and often.

What would be the cheapest way to accurately cut this shape out of a 3mm (11 gauge) piece of steel, without access to expensive machinist tools?
>>2792209What is your tolerance? If you need 3.507mm exact even precision manufacturers will tell you good luck with that.
>>2792211Oh wait now that I think of it, wire EDM can do it.If +-0.1 is enough then have it laser cut
>>2792209You're gonna need a sharpie, and JIS number 2 screwdriver, and a 20oz claw hammer
can i replace a 320x240 54 pin lcd with a 640x480 54 pin lcd ?
yes. as long as it has the same number of pins nothing else matters.
>>2791916>can i replace a 320x240 54 pin lcd with a 640x480 54 pin lcd ?Definite maybe, you might find distortion of the device and screen don't match e.g. missing vertical/horizontal lines, quadrupled pixels but misaligned. They can be fine, check begot replacing it you're doing a retro handheld etc. If you're fixing a game gear, look up how to recapp them. The originals leak quicker than most.
>>2791956>If you're fixing a game gear, look up how to recapp them. The originals leak quicker than most.already did, also replaced the oroginal diplay cuz it was fuckedproblem its a 320x240 and i noticed the pixels sont match 100%, where there is movement the image look weird, i thought it was because of a shitty mod but turns out all the 320x240 GG mods have that problem

>>2791552they make good single use seed trays, and you can "plant" them and they will rot away.if you want to go really diy, you can mix them with water untill you have made a mush, spread it out, dry it, and make your own card sheets. I have heard of people passing the mush through a sheet of fabric to make their own paper.
>>2791552We used to use them as drying platforms for small wood staining projects. (It sucked tho.)
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.

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

Do they literally just blow warm air over the food?some of them cost over £500. I already have metal boxes and hot wind isn't exactly hard to attain.
>>2792179In general you get a superior product from not using heated air. A box fan with some racks will make better beef jerky or dried fruit than a $500 dehydrator because it won’t cook the stuff as it dehydrates it. They all have pretty shit temp controls with wild swing, they’re just poorly constructed convection ovens, and when the heat element kicks on the temperature can swing wildly. I tried one (granted it was a cheaper model) where an rtd inserted in the chamber showed a spread of +-28F from set temp during drying. Critical reviews from people who know their shit seem to suggest the $500 ones have similar issues, though not as bad.
>>2792179>>2792191Diy dehydrator thread? I want/need one too. They all seem to be cheap, with more expensive ones just bigger. I want to dry herbs, spices and berries from my garden.Any more details on the diy box fan idea? I can work with rtds and relays. Should I add a big ceramic tile for thermal mass or something?
>>2792191>In general you get a superior product from not using heated air.now this is interesting to me, wouldn't that take fucking forever though? have you tried that? what was your set up?>A box fan with some racks will make better beef jerky or dried fruit than a $500 dehydrator because it won’t cook the stuff as it dehydrates it. so i thought the idea was that they don't cook it, just warm it, to about 60C max, which is enough to aid evaporation and make the drying quick enough that bacterial/fungal growth doesn't happen, which is what would happen with no heat.basically, in making jerky, if you just hang the meat out with no heat, i thought it would go rotten before it dries.
>>2792193>rtds and relaysyou can work with retards and relays? you are fully equipped to post on /diy/. carry on.
>>2792193serious reply now; i am thinking either, hair dryer on low, or even a heat fan on low, directed into the box. although i feel like they'd both be too hot even on low. additional internal fan for circulation because, who on /diy/ doesn't have a massive surplus of fans?I have a broken electric oven I can use for the main thing, has racks already.How much ventilation do these things need? I know they need some, i'd like a better look at the commercial ones, see how ventilated they are.>berriesyou could probably benefit from using some fine stainless steel mesh on your racks. could repurpose a sieve or frying pan splatter protector thingy.I might try to get something like a small radiant electric heater or one of those ceramic tube heaters.
