To 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.

How did you work out less than 1 W would be dissipated?
For your current, length, cross sectional area, and material I got 1.26 W.
This is assuming the copper is at 20 C, it will be hotter which will be worse.
>>
>>2968886
We have a copper strip 0.2mm thick, 8mm wide, and 100mm long. First, cross-sectional area A = thickness × width = 0.0002m × 0.008m = 0.0000016m2 = 1.6×10-6m2. Copper resistivity ρ ≈ 1.68×10-8Ω·m. Resistance R = ρ × length / area = 1.68×10-8Ω·m × 0.1m / 1.6×10-6m2 = 1.68×10-9 / 1.6×10-6 ≈ 0.00105Ω. Power dissipation P = I2 × R = 302 × 0.00105 ≈ 900 × 0.00105 ≈ 0.945W. Therefore, this copper strip will dissipate roughly 0.945W at 30A.

>>2968855
honest question: Do you seriously believe this is going to work in a finished product?
>>
>>2969371
yes I think this will most definitely work in a finished product and it is going into my robot and my robot is not intended to be a prototype as a coping excuse for why it is not fully functional or unimpressive it is intended to come out fully functional and impressive and fully capable right out the gates. Any sub-component that doesn't pass testing it will have to be redone but if I test everything as I go then I see no reason why I should not be able to have a reasonably robust system by the end.

If you know of something specificically bad or non-viable about the highside mosfet and its control circuitry and cooling heatsinking system shown in that photo that I am not aware of let me know. I am genuinely ignorant of any issues with it at all.

what is this crud that was locking the nut tight onto the threaded spindle? it was a pain to remove the propellor, but it was very easy to put back on. the pump looked free of debris but no longer makes the loud noise since i put it back together.

Hi /diy/, I'm in between jobs right now and lately I've been collecting broken appliances from the curb and checking the dumpsters around my local apartments too. I've taken apart a few microwaves and resold a couple working mini-fridges. It's not a ton of money but it keeps me busy. Any other scrap collectors?

Lead brained boomer, or bot?

Organic lead was added to gasoline for the sole and exclusive purpose of retarding the population, hand wave excuses are just that.

>knocking
Ethanol was known to work fine for the purpose, there was no non-malicious reason to add organic lead (which was know at the time to be crazy toxic) to gasoline.

Organic lead wasn't an industrial waste, it had to be manufactured specifically to add to gasoline. No non-malicious explanation, organic lead was added to gasoline with the explicit intention of retarding the population.

During the time that this was likely done people had a big chance of dying from aids, wo2, the vietnam war, alcoholism, smoking, breathing and eating poisonous stuff, workplace accidents, terribly unsafe traffic etc. This made people less careful/bothered about shit like this because reducing the chance of their house collapsing during their lifetime by 1% wouldn’t improve much overall. Only once all other risk factors started to decrease (safer traffic, safer work, better healthcare, food regulations) people started to care more about buildings and electrical being safe as well.

Recently I've been seeing these "overly meticulous and pedantic" home inspectors popping up on YouTube, namely this guy and his copycats. They claim to be "exposing corruption in the housing industry" but as others have pointed out, it's all part of the marketing. What do you think?

this guy isn't clickbait. had him inspect my new build home. it was all we could afford in a certain area, so there's no need to argue about why i would buy a house from one of these shitty builders. i wouldn't if i had much of a choice. but it doesn't matter, just because its inexpensive or cookie cutter doesn't mean it shouldn't be to standard. i am in the final stages of their fucking around right now and im looking at a huge paycheck from them because of it. so yes, his $450 inspection was worth it like 200x over. get your house inspected and have it done by someone who actually gives a fuck

Shower valves are among few things that sucks way harder in America then elsewhere.
My advise is you get a thermostatic shower valve. You can buy a $300 one from Europe or $50 one from chyna, it will be the same shit.
Seal the old hole with a stainless sheet.
I've done this on one of my showers.

>>2964163
Oh these fuckers. Over time the minerals in the water will adhere them into the valve like cement and you have to fucking chip them out with a hammer and flathead. That moen puller is the best at getting them out but it's also a good idea to loosen it up with the plastic thing that comes with the new cartridge. It happens to all types, but mostly when it's the last call of the day.

I just did the same job last week. The cartridge came out alright using the same style puller you used except the grommet on the cold water side decided to tear in half and lodge itself in the mixing valve. I also had to break off the plastic vertical tabs on the cartridge to get the puller to extract it properly.

The real pain was the old ass Moen handle adapter that fused itself to the cartridge stem. No amount of PB Blaster would loosen it. I eventually just cut out about a quarter of it with a rotary tool and then cut it clean off the cartridge stem. One more cut along the remaining cuff that was still on the stem and it was finally off.

I actually bought a pair of Geta recently and the design is just stupid. Both of those wood blocks/teeth are too far back, so you can't really put any weight on the ball of your foot without flaling forwards. The rear one is right up against where the strap connects to the body, but the front one is needlessly far back.

I know the nips love their tradition, but it seems intentionally shitty because it's such an easy fix.

For my work they are extremely useful, framer. Its not detail cabinet, trim type work, but when I frame wall and sheet it before standing and sometimes I sheet it after it's up. They make cutting out rough openings for windows, doors, etc. or cutting the excess off wall sheets/ roof sheets. It's a lot cleaning then the circle saw/recep saw combo. Or when the concrete guys fuck up the foundation and you now have to router each joists layout on the plate to match what's drawn they too are great there. Its a great tool but if you do work like this/that youd already know this.

Why 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...

get one of those jacket with armpit zippers. literally vents for your pits and sometimes a couple other places. good ones will also have zippers/velcro at the usual flaps that go along your shoulder blades to cover that seam and can be opened. going from a "breathable" outerwear to one that outright has holes in it right where you're the sweatiest but is a fucking spacesuit otherwise is a game changer. it's like those motorcycle helmets that have vents and fans in em, it feels cooler than just taking it off cuz it directs airflow around your body like a computer case

Is it possible to use IR to see people naked with smart glasses? How would I go about doing this? I noticed that some phones can't unlock if you wear reflective hats, so naturally that implies they can see your head shape through a regular cap and regular clothes.

explain Septic System to me like I'm a bitch.

Shouldn't there be an "Oh fuck" overflow outlet, like before even the first tank, so it can never back up into the house? I've heard of Septics overflowing into house. Is that illegal because your System has to work so you don't spread shit, so having it "sealed" is the way you are forced to have a valid system?

I'm thinking if I got a place out in the sticks I'd want to add an RV hook up out from under the house, and I guess I could also add an extra Y so I could connect a hose which could lead to an emergency over-flow gravity fed line.

WTF happens if your System is OK, but suddenly under fairly sustained excessive use? Will it most likely drain OK, but "water" not treated and live turd germs into Leach Field, and how bad is that and do people get in trouble for it? Does it start showing up in your neighbors well water and you get sued and a shitty rep?

Seems like any well designed system would include that, and into a normally dry pond or covered hole or French Drain or something.

I also saw diagram of a "solid state" dosing system that somehow worked without any pumps. IIRC it had a float and valve on a hinge on an angled arm so the valve would stay closed until "water" level well above it, then would open and drop level to well below float level. Seems simple and fool proof. WTF with pump systems. Seems like opening a big valve would be better than some little pump (that will be not just going on fritz but in the shit).

everyone is right so far
they do now sell cleanout caps that have a one way valve so if your house backs up it'll open into the yard instead of coming up your shower or whatever
but most people are oblivious and will just let their yard get covered in shit water for months before noticing so I'm not sure I'm a fan

Sure, buy an end cap that fits over the cleanout and remove the screw cap.
