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!
I hate the phillips screwthese black little shits always break, bend, destroy and spoil
>>2784904Used by automotive engineers to fuck mechanics six ways to sunday, retards at BMW motorrad had put them on the immobilizer antenna on the ignition lock, the problem is that all the antennas were getting fried when disconnecting the battery, the cherry on top is the medium strength loctite to lock the anti unlocking bolts. It took only 7 years to fix the problem and switch to a new antenna.
>>2784842>I hate the phillips screwim with you bro.Robertson square heads for life
>>2787159Most ignitions have some sort of security bolt these days. The one upside is that it’s in one of the few spots on a car where shit doesn’t get rusted and seized. I’ve run into those snapped off ones a handful of times, Dremel a slot into it or hit it with some Cobras and it should come out.Picrel shows the snapped off screw with the slot cut into it holding the ignition module on this thing.
>>2784855Whoever out there using Hex and phillips needs to be check for mental retartation
Why aren’t slotted torx more common? Advanced, versatile, relatively common drive + it’s a fucking slot, you can drive it with anything flat and hard in a pinch?
I am moving up north soon where everything is 3x as expensive. My new house has a large garage though, and I'd like to have a workshop. I just don't know what I should buy before I go to save money.
>>2790939You can use polyurethane or regular shellac as a seal coat before staining to prevent splotches. It prevents the stain from absorbing into the wood, and makes it work as a glaze instead of a stain. I would recommend this approach. Both are easy to apply to bare wood. It also makes it easier to remove if you want to change the finish down the road. The downside is that you get a little less of the stain color per coat, and scratches are more likely to show. Extra top coat can mitigate that.
>>2791772How much to dilute it, like 25% polyurethane to 75% denatured alchohol?Also, it’s amazing it seems nobody has come up a cheap alternative to shellac (or artificial shellac)
>>2791777You don't need to dilute it
>>2791777>Also, it’s amazing it seems nobody has come up a cheap alternative to shellac (or artificial shellac)Why? We have Shellac already, which is cheaper than Poly.
>>2791853Yeah, modern lacquer is essentially artificial shellac, but it's not cheaper and it's not universally better

>>2791423>>2791456Very nice, you guys. As an FT-847 owner I envy your filter selection and TCXO options.>>2791459Collins type filters are good. Only the Inrad ones have sharper skirting. By the way, there seems to be a steady demand for used filters for the 1000MP's. I had a hard time locating a Collins 500hz CW filter for my FT-847 until I found out the ones for the FT1000MP's were the same. Even then I found myself in a race to be the first to snag one from a seller and it took a few tries before I succeeded. I don't think the Collins filters are made anymore.PS. I can't help but see callsigns in the captvha. :^)
>>2791798Actually, i'm surprised to learn that MFJ was also Cushcraft. I knew they bought out the Mirage line as the older "brown faced" amps are considered superior. I prefer RF Concepts but I picked up a 160 watt Mirage A1015G. The odd thing is that i've never seen one without a mode (SSB/FM) switch. All the other variants show "50-54MHz" on the face but mine only has "50-52 MHz" so I suspect it's CW/SSB only.
>>2791781>blaming CovidWorld wide supply chains got into a mess that was quite real.
>>2791807They bought cushcraft in 2009; not all that long ago.
>>2791695imagine being such a boomer that your children don't want to continue the business and you listed it so high that no one wants to buy it from you. Bet he wants buried with his radios too.
1. Can I put up drywall on this box or does the bottom need more support than the 4 corners?79in long (6.6ft), 24in wide (2 ft)2. Do I need support for the drywall all the way to the edge to the wall where the railing is coming out of (14.5in long gap)
>>2791528Everyone blames the boomer parents, but they might have a point about keeping the door; maybe it saves money, or maybe they like the look. However. The fact that OP couldn't figure out a way to do that and also get rid of the fucking rails tells you this: OP IS A FUCKING MORON.This is the sort of shit we see here that has to be a troll, but the pics are too real.
>>2791531> they might have a point about keeping the doorAgreed anon. They probably think someday they will move out and they want the option of having a garage again.
>>2791787There is no door left
>>2790766OP you are going to spend way more in materials to cover the rails and lose head space in the garage than just cutting them off and buying new rails if they were to ever be used again.cut them off, man
why bother framing them in at alljust use them as a clothes hangerconverted garages are already white trash so you might as well embrace it
Trade Jobs Are DYING OUT...https://youtu.be/6DRm86qmXbs?si=BXi150ZR0VYKCqdQWhy is this so ???? >inb4 >yea low pay is going to be one of the main factors.https://www.npr.org/sections/ed/2018/04/25/605092520/high-paying-trade-jobs-sit-empty-while-high-school-grads-line-up-for-university
>>2791783Maybe if they paid more and didn’t expect 22 year olds to have 8 years experience.
>>2791783It’s pretty simple. Tradesmen usually take advantage of unskilled people. Young people actually want to do trades but don’t want to be taken advantage off. You can’t expect me to know everything if I’m a beginner. If you do get a job with these tradesmen, they usually yell at you and they’re pretty condescending. You don’t give people chances you expect everyone to be up to your expectations on the first day.
imagine actually having to work with 4channers.fat, fucked up teeth, retardedimagine having to go to work with retards everyday tolerating themit's the primary reason the trades are dying
>>2791783Your npr article about high paying jobs changes nothing.Companies bitch and moan about being unable to hire people or talk about how much their willing to pay but it's all lies.I remember applying to BNSF a couple years ago when they were offering $8500 sign on bonuses and paid training for 30+ openings. I was immediately rejected, no interview. I gaurantee almost all of these companies get plenty of applicants.And then my experience has been that when you do get hired, you will get paid much less than the advertised pay and raises will be much fewer and smaller than advertised.So why are trades dying?>yes, really, shit pay>dealing with shitty bosses>dealing with shitty contractors>dealing with shitty customers>dealing with other shitty tradies>dealing with shady business practices like not getting the pay or benefits or breaks promised in your employment contract/state lawThen you have classic boomer retardation to blame:Comment too long.

Any advice?
sounds better than night putting
That's what I did. Work during the day and then drag my ass to welding class once a week.Not much advice, the instructor will teach you all about it.
Shut up and learn. Things that seem stupid at first you will come to understand. Also fucking prep your shit. Buy three angle grinders now.
Hello. I would like to find quality hair clippers to cut my hair off with.I have bought this set a couple of years ago for a great discount, is this hair clipper a good model which should last me years?The hair clipper is a Wahl 09243-2616 and doesn't use a battery
>>2790310Got a Wahl ga-119 corded. It's pretty hefty, good blades and the attachments aren't flimsy. On a completely unrelated and pointless sidenote, Wahl used to make a spectacular cordless soldering iron.
>>2790598how much fucking oil do you think you apply to hair clippers you retard? I apply, like, a single drop of oil on my clippers after I sharpen the blades and even that is too much sometimes
>>2791267Are you talking about 20 years ago? I use a 20 dollar chink pair of clippers to go from 4-5 inches of hair to 15mm, they perform just as good as my expensive Wahl ones, they need charging every few YEARS. Cordless is good now.
Got my wife a pair of Wahl Senior corded clippers for Christmas when we were still dating. Needed a haircut before Christmas so I let her open that one early... Bitches love practical gifts.Looks like they still sell them on Amazon and they're $92. Buy them and use them forever.
>>2790314>>2790327Oster all the way.

>>2791814Hard coding models sounds prehistoric as fuck so I'll pass on openSCAD. Fascinating stuff though.I think I'll give freeCAD a shot. It looks the most familiar to me from my fusion experience.Thanks anon!>>2791815I mean anything is possible with the boolean tool.>>2791816The first part of it had a corner on the origin but its just a size reference for a PCB so it not really part of it. I think offset the perimeter to make the actual part so its all off origin now. I also moved the PCB stand in over 1mm so now its all fucked.Who cares tho bro :^)
>>2791813Why not just keep using fusion on the free license?
>>2788106>295CIs he printing too hot? I think he might be printing too hot.
>>2791076The 220-250mm range of print volume is my personal minimum. I have 240x240x280mm and I find myself using the whole volume fairly often. As well as printing diagonally for the maximum length.
>>2791231Lol for PLA I turned min layer time off and just blast the part cooler.
Why spend tens of thousands of dollars on campers when you could just build something like this out of free coroplast?https://www.youtube.com/watch?v=hltuJPPiCA4Hell you could even live on it.
>>2790389>"I'm not even six foot but this could probably fit a 6 foot 3 person"Yeah no, coming from somebody that tall, I'm not gonna fit in that piece of shit let alone sleep in it. That looks like the most miserable way to sleep.
>>2790976Painter Man was put on drugs by his dubious 'physician', after an attempt on his life that nearly killed him. Mussolini wrote that his friend would not sit down. They had him on a cocaine based drug, iirc, then barbiturates to put him to sleep. Late photos of him, just before he left, had multiple bags under his eyes. That wasn't just the cost of war stress. That was from being turned into a junkie.> trump 'phedrineGoing to need to see some evidence.> Putin must be on roidsIt's amazing how well you do when you work out, get health benefits from proper therapies, know and integrate certain things into your life, and e.g. aren't on fluoridated water, and don't drink (another source of fluoride, besides the damage of alcohol). This sack of fleshy protuberances I drag around is allegedly 50 this month, but everyone assumes I'm in my early to mid-30's. I know someone who is healthy and smart, like really smart not degree smart, and he's that kind of man. It's the kind of thing that you either have a bead on, or do not. When I'm 80, people will ask me 'what's the secret?'. There really is no one secret, they need to humbly open their hearts and eyes, internal and external, to what is all around them. Besides, by then, I used to think they will be 70-80 too, and it may be... rather late; e.g. I used to think they could have listened earlier, but no one thinks to ask or cares to. I used to think they are too caught up in other stuff, trying to achieve stuff of less significance, to me. God bless them: everyone has a course, I suppose. The more you bless your perceived enemy in his course, authentically, the more you defeat your real 'enemy'.>>2790954Most trailers will fit through a door frame.

>>2791705No drugs, then he was so badly injured he was going to die if they didn't do something.It's called 'time'. You're probably too much of a zoomer to have a watch, so stare at your microwave for awhile. See how those numbers change? Modern medications are for the most part, less addicting. Back then, all they had was crack, dope, smack and alcohol. Once that fraudulent physician got his hands on his health, it went downhill. He was surrounded by some loyalists, and lots of enemies.
anons im having trouble selecting ideal transistors for use with an RF amplifier design < 100mhz. It seems that the tradeoffs are just too great- you either have low impedance gain or high impedance gain, and you either have low current and low noise but also poor handling, or high current and higher shot noise. rBB is a big part of this and is rarely documented, because it's usually lower than other noise figures. beta is sometimes very high but this isn't necessarily a good thing. have been reading a bunch of documentspic related, this shit pisses me offwhether it's nexperia, onsemi, nxp, zetex, or infineon, choices for good transistors designed for HF are limited and most offer shit noise figures or require end users to test tons of models to characterize what the mfg didnt think importanttrying to design a loop amplifier based on wellbrook and has:good linearity from 5nv to 500mV, positive gain from 100khz-10mhz(used a LPF 2nH capacitor for this)consumes under 100mA(ideally under 30mA) of current, powers off 3-5V bias-T power insertreally good, low noise figurehave had some good results with phemt but biasing them while keeping self-oscillation down is harda few good jfet exist, but the square law behavior is not desirablelearning transistor behavior has been a giant pain in the ass and it feels like nobody designs transistors anymore for HFits all crap they designed decades ago
someone is actually transmitting something worth listening to below 100mhz?
>>2790407Can't you pick transistors designed for even higher frequencies (VHF, UHF)? Or is all that stuff done monolithically?
I hate to say it but what you're experiencing is par for the course for RF design, from shitty and downright incorrect models, to a complete lack of perfect-fit RF transistors.You need to design multi-transistor amplifiers and lots of buffring.This is the only way you might possibly get the performance you want. Look into cascoding.>>2791835Pretty much anything high frequency is done monolithically nowadays

>>2791571.noise doesn't generate noise. it analyzes noise and plots noise voltage density. if you need a specific spectrum, you could generate time series in matlab and load it as PWL file. or you could generate a WAV file and use it as an input.
>>2791659>if you need a specific spectrum, you could generate time series in matlab and load it as PWL file.interdasting. thanks.
>>2791206With all this simulation nonsense you could have built it with a zener diode as a noise source and measured it in less time.
can I create multiple PCBs in a single KiCAD project?I want to create a seperate mainboard and power supply PCB.
>>2791828I don't think so. I think the idea is you have multiple KiCAD "projects" in a subfolder for the project as a whole. I'm pretty sure you can have multiple files open at once, but it doesn't really feel intentional, and the netlists not porting over is a pain. With normal PCBs I often swap op-amp A for op-amp B to see if it makes routing easier, in this case to swap the pinout of a board-to-board connector you'd have to swap the nets around on two seperate files.You can probably just have two seperate edge cut outlines in the same PCB Editor window, but that enforces they're both made of the same PCB stackup (can't do single-sided power board and 2- or 4-sided logic board like on a TV), and they might be a pain to get fabricated. DRC might yell at you too. Maybe that's what panelisation means, idk.
I'm worried about hammering nails into wires when I'm hanging paintings. I'm gonna get a stud detector/wire finder, but I've seen some people say these are unreliable. Should I be worried? I really don't want to hurt myself or need to have electrical repairs done in my house.
>>2791168Any device is almost useless with plaster, especially the exterior chicken wire types. But you can find the stud spacing inside, guesstimate the wall thickness, then just trial and error with test drilling. Until someone invents an affordable handheld Superman Vision device, that's my advice, and I've mounted 65" TVs on exterior stucco walls.Sucks, but it is what it is.
>>2791167This is why I use cobalt drill bits. Multi-material screws going through a layer of drywall, the corner of a stud, some cast iron pipe, and a bunch of wires gives you the best hold ever for those gay ass floating shelves!
>>2791040I picked up a $500 SEEK brand one for $200, thinking I could finally have a good stud detector. Was disappointed. It’s helpful for finding the occasional vertical stud, but mostly it just works on the ceiling. On some external walls the insulation behind the dry walls isn’t so great, so there is a larger temp difference, but yeah I was bummed. On the flip side, it’s rad as fuck for when I’m out camping, or doing astronomy alone at night. I get kind of creeped out, and it does an awesome job detecting animals and people. I have a black dog that basically vanishes into the darkness, and could finally see where he would be, and not worry about coyotes and shit. It’s good for pcb, but reflections make it harder. Reflections In general suck, like looking for leaks in a plastic tarp greenhouse. I thought I’d be able to see like het in the air escaping. But stead I just see reflected heat off the plastic.
I found out I have drywall that's about half an inch thick, so I figure nails are probably a no go. Have you all heard of monkey hooks? What about drywall anchors? What do you think would be best?
>>2791810Those monkey hooks are good for hamging pictures and stuff. And there’s half a dozen different types of commonly used drywall anchors depending what you want to do.
I want to do stuff like pic related, clearly starting with something smaller and work my way up, have some space, have not too much money but I have time.I don't know anything about stone, how do I start? Just buy a hammer and chisel and carve away?
>>2791262>Just buy a hammer and chisel and carve away?Literally yes.
>>2791556This.And a face shield.I've got a little scar where a chunk of stone hit my cheek.
use a pencil to mark the form
