The only two trades that ever mattered were masonry and carpentry. Everything else is just superfluous shit.

>>2983949Bro, do you even lift?I'm 70 years old an my ladder is no problem.
>>2983949They're heavy, but I like mine because it's versatile enough that I don't need other ladders. The ability to have the legs at different lengths is great when working on the outside of my house. If I used it daily for work I'd probably get tired of it though.>>2983893Wondering this too.
>>2983973I lift metal plates, not metal ladders>>2983974I had to use one for a job once and that was enough for me
I have the Little Giant Velocity, pic-related. I just used it to clean my windows and gutters. As others have said, it's pretty heavy. It is pretty damn stable and well-made though, and I feel safe when I'm high up.
>>2983949If a 16' Little Giant is getting the best of you, stay away from any kind of 40'. Those will put the fear back into someone at every stage of the process.
I would like to weave chain mail, making rings for it from wire. Has anyone had experience with this? What metal and what diameter wire is best to use?
>>2983604Basically, if you're gonna make maille you may as well do it right and get it riveted. That shit is no joke with how strong it gets once they're solid.You could cheese it by spot welding each link as well but where's the fun in that?
The only rings that makes sense to coil and cut yourself are overlapping mild steel for riveting. There is no reason not to simply buy premade rings for any other purpose. The cut quality and consistency as well as the time saved is very much worth the extra expense.>>2983606you can also use a punch to make solid rings from sheet metal and save some time riveting every ring that way. This was also done historically.
Don't try to make rivet mail first, it takes four times longer to make than butted. Decide if you enjoy the craft or not before committing to that.
I made chainmaille for a project in high school 18 years ago...just used galvanised steel wire from the hardware shop. Made a wooden frame to hold a mandrel at both ends. Mandrel was a metal rod with a hole in one end. Chucked the rod in a cordless drill to wind the wire on. Then I think slid the finished spring off the rod and cut it into rings with big side cutters. Used to do that on the lounge while watching TV kek.

I want to make this: https://baofengtech.com/wp-content/uploads/2020/10/X-Band-Repeater-BTECH-Mobile.pdfBut I'm getting hung up on where they connect the mic in on one to the speaker out on another. I'm measuring +5V DC on the mic input, presumably to power the handset lights when that's plugged in.Would that damage the circuit driving the speaker output to constantly have a 5v bias like that?
>>2983870That terminology seems to imply a quadrature detector, but yeah that's where I've seen it. A quadrature detector is really just a pair of mixers and offset clocks. But there's nothing stopping you from using an SPDT analog mux with a single differential amplifier as a balanced mixer. Though if you have to use that differential amplifier to combine the two halves of the signal that requires that the amplifier be rated for the RF signal if it's being used as an upconverter, but I'm pretty sure you could use a DPDT analog switch as a mixer without needing a differential amplifier.>>2983885The +5V is a high impedance bias for an electret mic, IIRC on my quansheng there was a smaller DC bias on the speaker output. For my IEMs I stepped down the signal with a diode clipper (because the PTT button puts a big voltage spike on the speaker line) followed by a voltage divider to drop the signal amplitude to something sensible for high-sensitivity IEMs.
>>2983882what would this be for? rx? tx? also, what about the built in mixer of the cb radio? could i plug the signal in somehow?i think the radio has oscillators which get added to other oscillators to get the desired frequency. so i guess there are mixers in it, since it has fm/am/usb/lsb there might be multiple mixers.its fairly well described in the service manual but i'm a noob so not making much progress on it.
>>2983988You should probably look up how mixers work, and what radio block diagrams look like.

I purchased two 2 in (50mm) circular lens which I need to run in series to collimate a beam of light. The problem is that they are circular (duh), and need to be secured. I was originally planning to fit them in a series of 2 in couplings but it turns out that plumbing fittings are a hair shy of 2 in. I think I will have to file them to make the couplings to get the lenses to fit but I wanted to know if there is some time of pipe out there which actually has a 2 in inner diameter before doing this.
>>2984054about 3:30 but I don't think I can make it.

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.
>>2983541Thank you I'll try
>>2983538>once I get the arm working, the robot will build everything else after that using that armtruely staggering
So what kind of sensory feedback are you going to equip this arm with so it can know, what angle every joint is, how much force it is applying, if there is a failure or wear compensation.like will it have strain gauges all through the "bones", radial encoders for the pivot joints, cameras, lidar, gyroscopic/inertial sensors to watch where the arm is in the world?
>>2983931potentiometers for every joint to measure joint angle. current sensing for every motor to measure how much force each joint has applied to it since that maps to current pulled by motor. As far as cameras, only for the eyes (in them). gyroscopic/inertial sensors will be in the main body for overall balance but not in arms. Lidar is a dead end for robotics and not to be used for humanoids.
>>2984026>Lidar is a dead end for roboticsAre we sure this isn't just Elon Musk's identical twin brother "Nole" trying to get Optimus working?
Have you ever just went ahead and ignored all laws, zoning requirements, and permits required for construction?How did it work out for you?
Guess it depends on where you live. The county inspector hereabouts kept trying to get on my property to look at it, but it was always when I was at work, and apparently he can't just "show up" and look around without written permission. (kentucky thing I guess)I finally took some time off, he wandered about, said it looked fine and warned me about the crazy old couple up the road who thinks there's a HOA here.Yeah, they eventually came by trying to "collect HOA fees". I invited them to fuck off or talk to the Sheriff.
>>2978218That sounds like an old outdoor light run. My older home has them. The telephone as wire I'm assuming was just small cheap wiring they could run outside quickly.
>>2977936you will 100% get caught on this. tax assessors pay services that use satellite data that report annually the location of all new structures in the county visible from satellites. when your address shows up, you will get a visit.you can probably get away with like a tool shed maybe a small carport, but an entire pole barn 0 chance.
>>2983593depends on the cityt. scofflaw
>>2976196I did it on my rehab project for a rental property i bought and neighbors reported me I think, in any case I got red tagged and had to pay fines and buy the permits anyways. One thing I learned for sure is that if the condition is very bad on exterior then they know you are doing a full gut rehab and know you need permits for sure so you can't get away with it. If its nice exterior and you work inside only mainly you have a better shot to get away with it?
In short, has anyone here looked into Wolfia Globosa as a food to grow in the limited space I have. Does anyone here have experience with it, or thoughts about it in general?To get started I'm planning to grow it in a wide metal washbasin I have, covering it with plexiglass roof and mosquito net sides to keep rainwater and insect away from it. It's a small tray though, so I'd need more space to grow any significant amounts of it. All hydroponics basins I've found are made of plastic, and I'm worried that with Globosa being an excellent bio accumulator it would also be excellent at absorbing microplastics into it. I'd need a total of 4 square meters of 20cm deep water, so where could I get large, wide, non-plastic basins for it?
>>2983927Stainless steel sinks, they have a built in drain and could last decades outsideCheck ali express for industrial sinks/wash basin
Look for old bath tubs in the trash. As long as you don't mind cleaning it up, both the fiberglass and iron ones will last forever and neither should leach anything. Farmers use they as watering troughs for livestock.
>>2983938Thanks! I should clarify that the wash basin I currently have is about 2 x 0.75 meter one made for washing carpets, and what I'm looking for is something with several square meters of surface area. Something with the surface area akin a kiddie pool, but shallow and made of metal or some other non-leaching material.>>2983975Bath tubs are unnecessarily deep, as the water only needs to be about 20cm (about 8 inches) deep.
>>2983984>several square meters of surface area>8 inches deep>can't be plasticThe likelihood of finding something prefab meeting those specs I think are going to be pretty low. If I needed what you're describing, I would probably have a piece of sheet metal delivered, 16" larger in each dimension than the tray, and use some boards and a hammer to bend the sides up and fold the corners over, forming the tray. Or using a metal brake if you have access to one.Like this, only on a larger scale and without mangling it in the process:https://www.youtube.com/watch?v=rcDhx2IJdtE

This is the longest I've ever held a job, and I actually enjoy it for the most part. But I asked for a raise at my three month mark, and the GC basically told me I'm too incompetent and replaceable to deserve a raise. I took it to heart, and ended up blowing off the next workday because I was so drunk. I guess I sort of assumed I could find another job, but they were all too far away (even if they paid more), so I came crawling back.Apparently my 12AM text woke him up, and that's mainly why he said "my respect for you went from here '-' to here '_', but instead of firing me he just transferred me to HVAC. I don't think he hates me, he just doesn't want to deal with me anymore. Apparently I'm "doing a good job" in HVAC as a total beginner (although it was recommended I apply more deodorant). But I'm still capped at 15 an hour. And I had a conversation with the GC today, about what economic value there actually is in bringing a new helper onto the crew (when it's been a three man job as long as I've been there), and he called it a 'mind-boggling question'. As in, it's a waste of time to ponder the systems and frameworks behind all of this in an economic sense.I would chalk it up to 'neurodivergence', but then again, it seems like just about every coworker I have is always talking about their "ADHD" or "dyslexia". The designer is literally a diagnosed sperg and it shows.It still feels like a hostile work environment to a degree, but I'm just grateful to have stable income. From what I understand, autonomy and efficiency are what's most valued on a jobsite, and I guess that's basically the reason they told me I'm not eligible for a raise. But the GC also said that "we don't discuss wages here" and the HVAC guy said "I'll let you know when you get a raise, don't ask", which seems like a red flag desu.Call me a faggot or a retard or whatever, thanks for reading my blogpost.
what a bunch of boomer mindbroke niggerfaggotsit was sop for years to have a 90 day review and pay bump at every job and anybody that says otherwise is full of shitbut this is a b8 thread so nevermind
Trades/construction is fucked, always. Sometimes there are decent guys in there but it doesn't matter, every company or general contractor is a fucking parasite that has to compete on being more parasitic than the others to survive. They don't have a choice. They chew people up and replace them like dull blades, never bothering to sharpen them because it's faster to just throw away the old shit and buy a new one. That's why they act like every job is life or death, I've had a few unironically ask me to jog from place to place on the job site instead of walking. Like dude, not my problem you massively underbid this contract.The work itself is fun, but the corporate nature makes it insufferable. Best to keep these things as a hobby and gtfo of the industry, it's not gonna get any better. They're gonna keep importing poor brown faggots and threatening them with deportation unless they work for $5/h which drives down wages and expectations for everyone
>>2983501>ask for raise after 3 months of on the job training>no call no show>drunk>body odorYep, you really are meant for construction work.
>>2983845the "chuds" you're imagining are those who work fake email jobs in the office.
>>2983501>But the GC also said that "we don't discuss wages here" if you live in a one party recording consent state, get him on audio saying this then talk to a jew lawyer who will work on contingency.

>>2983626it's a bitch cleaning out the S shape ones, two piece is by far superior
>>2983623The screw caps always seem to leak, stick them in a rubber stopper instead. It’s not a problem with the airlock type
>>2983623>Is there an easy way to tell if these style of airlocks have a good seal?No bubbles while fermenting is surefire. Quick and dirty, get some clingwrap and try to form into gaskets for bottle against cap and cap airlock as both look dodgy.Are you reusing pet bottles? I do this with 5L bottles and it the original cap/bottle seals fine without gasket. Drill hole and use a gasket as for bucket lid to seal airlock.To check if the seals are really tight you need empty bottle, fill with cold water from tap. The water wil off gas enough that your airlock will float and stay that way. Wait about 30 min to make sure it doesn't sink.
Trying my hand at brewing some simple mead with honey (naturally), some apples, and cinnamon sticks. Also bread yeast. This is after 10 days, just before I siphoned it out and then back into the bottle after cleaning. Gonna sit there for a few weeks now, then I'll cold-crash it to attempt to gain a little clearness and drink it down.Looking forward to seeing how it'll be. If it's still as good as the tiny taste I got when suck-starting the sieve (like mead, mm) then I'll consider it a great success, especially as I half-assed the whole process.Looks like you guys get reaaaal fancy with your brewing setups here. That or wine/beer is a lot harder to brew properly.
>>2983730>>2983768Local brew store was out of the right size rubber stoppers to fit in my half gallon bottles. I didn't want to drill holes in the original caps since I'll probably reuse these (I'm a cheapskate) and it's useful to have a cap on hand that can totally close themAll that said, the float in both airlocks is raised, which must mean they're holding in some amount of pressure, no? If the seal isn't perfect that's fine by me, it ought to be enough to keep out the nasties.>>2983865>reaaaal fancyIn my experience mead is so forgiving you can make it prison-style and be just fine. >>2982556 was fermented in a 1L plastic bottle I happened to have, with bread yeast and a loose cap for the "airlock." No sense wasting the fancy gear on a test batch
