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!

what is the best way to split a long but thin panel while making it easy to accurately put the thing back together? This thing is 300mm long and 6mm wide. i could print it standing up but i need those rectangles to come out perfectly so i can't do that.
What's the most heat resistant filament that's without carbon/glass fibers? Printed a custom part cooling duct with ASA but people said it eventually warps (it touches the heat sock).
>>2965812Can you have fasteners protruding on the top and bottom? I'd want to print two pieces with 10-20mm wide pads that are 3mm thick instead of 6mm on the intersecting ends, and screw them together with screws through these overlapping sections. With short screws and threaded inserts in one side it might be able to not protrude from one of the two sides.What does the part do? It strikes me as the sort of thing you could get ordered waterjet cut from sendcutsend or whoever.>>2965813EasyPC is probably the best balance between printability and temperature resistance. Some polycarbonate filaments are much less warp-prone than others, I hear Prusa's is the best but never in stock. If you have a heated chamber it's probably less of an issue which one you get. Though if you don't mind setting the thing in sand or plaster of paris, annealed PLA goes up to 150C. There's also nothing stopping you from printing a mould to inject epoxy into, maybe pre-filled with carbon/glass fibres.
>>2965812Like the other guy said, overlapping tabs, but use glue or a solvent bond instead of screws.
>>2965815>It strikes me as the sort of thing you could get ordered waterjet cut from sendcutsend or whoever.yes it could be very easily lasercut but i want to do as much as i can at home.>>2965817do you know of any glues that work well with plastic and wood?i think i will just go to the hardware store and buy some wooden profiles to put into the wide slot. together with some glue and generous and evenly applied pressure it should come out straight, right? Then with a cut like here the top side should also be aligned.

>custom antenna on roof gets worse reception to local 2m repeater than stock antenna handheld held out windowyou know, i took down an unused tv antenna to put this antenna on its polewe didn't use that tv antenna because the reception from the local mountain was blocked by some big trees, and use satellite tv insteadthe repeater is on the same mountain as the tv antennai am a moron
If usps doesn't deliver my antenna tomorrow that was supposed to be delivered Wednesday I am going to kill myself
>>2965336How goes it, anon? Are you metering out coax or rope?

>friend tells me americans build houses out of paper and toothpicks then pay half a million dollars for them>obviously he's joking, have a laugh>look it up later>it's realDo you "people" seriously do this? Use flimsy twigs and literal fucking paper to build your dwellings?
>>2964957If the state tries to tread on the people, the other people will cheer them on.
any moron can overbuild like a caveman but it takes brains to build with the exact amount of durability and strength needed for the purpose
>>2965077>the purposeaka "stand up long enough that we can sell the house"
>>2965090don't you people househop anyway
>>2964759Correction: Japan does (or at least did) wood and paper houses, Americans moved on to wood and styrofoam. They also usually get covered in a thin slop stone veneer (drywall, stucco, faux stone or brick cladding) to make them feel solid and to pretend they used better construction methods. Those will last for decades with reasonable upkeep, which is long enough to pay off the mortgage or get obliterated by an earthquake, wildfire, tornado, or flood. If that happens they get rebuilt with an equally temporary building because that's all the insurance will cover (if you're lucky). People with enough money to have a home custom designed still mostly go the same route because as >>2964781 said, higher quality means higher cost. It's simply quicker, easier, uses less material, and is certified Good Enough. Few people are worried about what their place will look like after the few decades max they'll spend in it before moving or dying. The country as a whole specced into this method mid last century because the plywood industry got huge during WWII. The war ended but those plants didn't shut down, so there was a yuge surplus of cheap domestic building materials and wouldn't you know it people were safe and happy and fucking like mad and needed a lot of new houses on the quick. Homes from that era are still around, roofs replaced, hopefully wiring updated, maybe even asbestos free after one of the times it was remodeled. Not really a big deal. A well kept 50s/60s home is better than your average new build because later homes have more corners cut. Thinner plywood, lighter and greener framing, more foam, but still (generally) functional as dwellings. >>2964966What's the cost and size of your place? Looks nice.
wtf happened to this site? no machinist thread???Ask machining questions, post machining failures.CAD CAM talkSpeeds and feeds guessingG-Code, M-Code, Bro-CodeFanuc vs HaasBitch about payIgnore SiegWhine about spline shaftsButton pushers who think they're machinists
>>2965133I have an associates in mechanical engineering technology. I run a small machining department that has 2 shifts, 4 mill machines, and 6 machinists. I used to do swiss machining but that shop went to shit
>>2965769Work mainly, but not a lot of it, just testing designs before sending the files off to a separate manufacturerWill also be doing some personal projects on itAnd correct me if I'm wrong, but isn't Acramill one of the more reputable companies?
>>2965799>one of the more reputable companieslollmfao even thats like asking if kroger frozen peas are better than safeway select
>>2965804Sorry I dont know much on the topicI figured I might just be able to machine upgrades for it, I don't know if thats unrealistic or not but i can definitely design the parts
>>2965809its not so much upgrades as the issue is the fit/finish of the moving parts often sucks on the chicom knockoffsbut even a knockoff bp is better than a drill press. so slap a $200 chinkshit dro on it and buy a real kurt vise and start making chips

>>2965721Yes but when you just have a tx/rx coming out of something to work with then it's another story
>>2965723Ah so you have an existing UART signal and you want to send it across RS485? Where's the signal coming from? You could likely use a 555 timer or similar to enable the transceiver's output for a bit more than a full packet's width. I don't think it matters for the strict UART-speaking thing for it to sense when the bus is idle or not, maybe you'd want a pull-down resistor to ensure the default state is a zero when it's idle if the IC doesn't assert either way.
>>2965723>>2965740Oh and either way, if it's just designed to produce UART, it won't be able to respond to a bus collision. If it ever tries to transmit data onto the bus while something else already started, the data will get jumbled for both packets.
>>2965721This. You need an extra signal to turn the RS-485 transmitter on and off. And of course on the receive side you have to ignore your own echos.
>>2965754>ignore your own echosI figured if it were half-duplex (which it probably is but idk) then it wouldn't matter, but either way you could use the transmitter's enable signal to disable the receiver at the same time. Pic related is a chip from TI where the drive-enable and receiveenable pins have opposite polarity so it's as easy as connecting them together. Though it's not exactly a jellybean, it was the first one on TI's table and it's a $230 radiation hardened chip. The THVD1505 is more of a jellybean and has a basically identical diagram. Though the internal pull-downs and pull-ups will cancel.Otherwise there might be smarter chips that actively handle idling the bus and bus collisions, and store data to an internal buffer that's accessed via UART. Worst case you can implement this feature using a little microcontroller between the UART source and the RS485 bus transceiver.
I am designing a house, based off a kithomeMy girlfriend says she wants to have a lot of kids, so three smaller bedrooms would essentially be boys, girls, toddlersThe concept is that the less used rooms like bathrooms are on the street side of the house, and the house is as far front of the property as possible. This gives a larger backyard with the living room and all bedrooms having glass sliding doors that open directly onto the rear deck into the garden. not sure about that toilet on the left. Bathrooms all have double showers because it's really a cheap thing to do, and allows efficiency in the morningI think the Rumpus would be kind of a computer room for kids to have their games consoles and computers in a space that's still public, but not going to spread noise to the whole house
>>2953578>must me fun living in a stable... not >americans are fucking retarded i swearThe only explanation for this, is its a jeet storage warehouse someplace in Canada.OP is looking to pack 50-75 jeets in a small area. Theres no other explanation for how retarded it all is.
>>2952375>the RumpusWTF rumpus?Why does your self-designed house look like a double-wide trailer?Which way is the sun?One of the main rooms should face the sun, unless you're in AZ or TX.

>>2965777Dark-field illumination exposes a lot of defects too. Good for finding broken traces and corrosion damage, among other defects.
>>2965748I would have thought louis would have given you a lifetime’s supply of flux
>>2965577I think it's a holdover from almost 15 years ago when individually addressable LED strips were somewhat hard to find. They had documentation in english and shipped from US. I almost bought some but the price was outrageous even then.That reminds me, anybody remember when the big thing was like 10 x 10 x 10 cubes made of 5mm LEDs with the legs soldered together?
>>2965084I ordered the most popular set on Amazon for ~$20 and the only delivery option was Christmas Eve. Sorry random delivery driver
>>2965748Cool stuff. I've seen those ring lights on alibay for under $30, but I don't know if you got a branded one. I also recommend the polarised technique, but from what I understand you want to be able to independantly rotate the light's film and the microscope's film. That might require a fair bit of funky work, especially if you don't have a 3D printer.>>2965775>but I started doing SMD shit of a size where working without a magnification is really a huge pain in the arse and my eyes aren't getting better with ageYeah fair enough, I don't exactly do any computer or phone work. My eyes are steadily getting worse, but for now at least it's nearsightedness in one eye that actually makes electronics easier. What isn't easy is having my workpiece 150mm from my eye without straining my back. I hold my breath, a fume extractor is a good idea.>If you spend 50-60 bucks more you get a camera port on them, "trinocular" but I have no need for thatI gathered that from the above posts, if anything I'd just want a lens assembly that only has a camera port. Mainly for inspecting boards after I've soldered them, or trying to reverse engineer them. I guess it's feasible to use a really long exposure and light the board from behind to see through it.>But i find you can zoom in at like 10x or 15x and still have easily over 100mm working distance and enough field of view to work withGood to know.>>2965778Hm, I wonder how polarisation of the light or camera effects this? I know glancing reflections are preferentially polarised so it might not be that useful. I also wonder how useful it might be to light up the subject from different directions/polarities with different coloured lights, though I guess it's less useful with a binocular microscope.>>2965794Comment too long.

Stupid questions that don't deserve their own thread. Last one hit bump limit
>>2965717brand only really matters for battery systems and hard use systems. i use milwaukee for battery stuff and festool/mafell/mirka for my corded stuff. i spend a lot of money on tools because i use them to make money and they make me a good amount of money so cost doesn't really matter to me, i buy whatever i think is the "best" tool for whatever i am using it for.>festoolmakes everything and it has sexy storage boxes and you can flex on the poors with your shiny tools you never use. it has a great warranty service too, but you will never use it because you have to work these tools really hard for them to break.>milwaukeehuge step down from festool both in price and quality, but they have some things which stand out to me. the only reason i use milwaukee battery tools is the Surge impact driver which has oil in with the anvil and that makes it quiet. i absolutely love this and think it is a great innovation. their multitool is also head and shoulders above the other "home depot/lowes" brands, that fucker rips. they also make every fucking tool out there so i even have a milwaukee electric grease gun.>dewalt used to be the gold standard for tools but their new shit doesn't keep up with milwaukee's new shit. that being said, their miter saw and table saw are the best "home depot" level options>boschi have their gravity rise table saw and have been running it hard for 7 years, it's still going strong. their weak spot is their battery tools IMO. every single bosch battery i had has now failed and won't even take a charge. the impact driver i had from them had the "speed select" button break and now it's useless. i would avoid them for battery stuff.>metaboi would only buy a made in germany corded grinder from them. prior to the bosch drill/driver i had a metabo drill (made in germany) that had battery issues and speed select issues (basically same problems as bosch).>ryobii break their stuff when i use it
>>2965651that would be my preference but the screw for the handle is like corrosion welded into the valve. won't budge

>>2965547Propress is shit, you're replacing a soldered joint that will probably last 50+ years with a couple of o-rings that might last 25. Great for retards who struggle with getting a good solder job, and professionals who can save a lot of time on jobs they won't be around to see fail, but stupid for homeowners who don't care about spending an extra minute to do the job properly.

>>2965478Fat quarters of fabric maybe, I know I would like that. Make me some nice bias tape out of that.
>>2965112Thanks for the answers. Where do I look for these attachments? eBay? Craigslist?Also, as long as I'm asking, the manual says not to leave the machine plugged in once you're done sewing. Is that a hedge against 1930s power outlets, or should I keep unplugging it?
>>2965589Hedge against 1930’s pedals lighting the house on fire. J/k but they use nichrome wire as resistors and always consume some current when plugged in. I finally just spent a few bucks on a modern replacement for mine.
>>2965589eBay and shopgoodwill.
>>2965589I've found all the attachments I have at thrift stores, mainly the ReUse junk store kind of ones rather than big name thrift stores. The machines there are often overpriced but the accesories often look like archaic stuff people can't recognize so they sell them cheap.
I have an 1100 Square Foot Uninsulated Garage, and a 30K Kerosene Torpedo Heater. How can I give it a fighting chance to warm up the space?
>>2965672You should ask him what his waistline is, also his race.
insulate the foundation as best you can, increase drainage. dig trench stuff in insulate board, dig wrap around cement border put insulate board under that before pouring concrete. the cold is going to get in the changing of materials slows it down, temps stabilize the deeper you get so an L shaped thermal barrier and some gravel will slow it down from soil and water.
>>2965677>You should ask him what his waistline is, also his race.What does that have to do with anything?You should probably step out of the thread if you've never worked in the cold in your life. Coming from zero degree weather into a shop that is heated to 40 degrees is t-shirt time.
goddamn im glad i dont livein snownigger landits 65 and pouring rain here and like 85 in the house and im sweating my balls of sitting around in my underwear but the shop is fucking gross. water dripping off of everything. you can watch bright steel rust in front of your eyes so everything has to get firehosed with wd40 to not become rusty shit
>>2965787>its 65 and pouring rain here and like 85 in the house and im sweating my balls of sitting around in my underwear>fireplace blazingWhy though? Also where I live it routinely gets to over 100 degrees in the summertime and we've had some -30 cold too... Few years back we had -20 for two weeks during the winter. That wasn't fun at all. But it's amazing how much your body will adjust to the different temperatures. Coming out of summer the first day that falls below 50 degrees and you're freezing your ass off, but once you get used to it it's not that bad. Hell after a couple weeks of -20 degree weather, once it warms up to the mid 30's you're running around in a t-shirt because it feels that damn warm. Then when springtime rolls around and it gets up to 85-90 you're about to die again...

Due to personal circumstances, im currently living in a tiny bedroom with barely any space for anything. I have a desk, a nighstand, and my clothes mostly go under the bed in a plastic containerWhat are some tips and tricks for taking full advantage of such a small space?

Pay $650 US for a wooden loft bed or could I make it cheaper myself without compromising on the quality of wood?
>>2965772Define quality of wood.Do you want hardwood that looks nice? Is this 650$ bed made of hardwood?If it is the typical soft pine I expect, you can make it cheaper yourself, but you need to know what to look for when buying wood to avoid quality problems that will lead to bad fit due to warped/twisted wood.2 by 4's for building are usually rough sawn and not precise, you want to buy pre-planed wood for furniture and make sure it's not twisted or bend.
