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.

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?
>>
>>2983931
potentiometers 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.

Ok I used the tip of my exacto knife to carefully scoop on low temp solder paste and then carefully drag soldered it over the key areas I wanted pre-tinned. There do not appear to be any short circuits and the amount of solder on each pad and trace seems a decent amount to me. I forgot to wipe it with alcohol wipe but have done so since taking this snapshot. The next step is I have to carefully uv cure solder mask that little trace runs under the IC chip. It definitely will short a pad to something I think if I don't. I have to apply it very thinly so it doesn't prevent IC chip from seating flat and soldering into place well.

I know prepping is a bit of a meme, but what are some of the best food items to store long term?
Is rice one of the best emergency foods? It’s cheap, it lasts for a very long time if kept somewhere dry (relatively easy to store), and a person can survive off of it in dire situations.

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.

I've used tons of different pressure washers.
I like electric, but their underpowered for the price. A 3000psi electric is a light duty go to for me.

If you need heavy duty go gas. But it's annoying as fuck doing maintenance. But if your cleaning like industrial grease from a restaurant go gas. Aside from that it probably doesn't fucking matter.. all pressure washers are basically the same.

It probably really comes down to gas vs electric and not much else.

Very true.
When I joined my company, one of the first things I set out to do was automate this monotonous and annoying task that we would periodically get throughout the week. It's literally just pulling some files from a web service, uploading them to an S3 bucket, and running a job through a third party web app. Automating that process was easy as hell, but there would always be the most seemingly inconsequential revisions that would need to be made to those files for it work, and it was never consistent. Way too much contextual information required to do it right.
>inb4 just use ai bro
This is an incredibly complex system that interfaces with ANCIENT mainframe code. AIs today don't have nearly as much training material on mainframes as it has webdev shit. AI is useless in this context, not even considering the crazy obscure business logic that drives all this code.

i work in school IT.
the issue isn't the AI, its the retards accepting AI's word as law.
half the kids who come through with dead machines did so because they followed the ai chatbots suggestion to go to "x" website and install the newest drivers, with a link to a 5 year old linux BIOS.
so they brick their windows/mac install, while trying to google how to access their onedrive (all they had to do was log in).
until the AI can remove the step of "belive what a human tells it" as truth, and plug in a power cable to a screen, while ignoring the user blaming some iphone update from a week ago, i'm still in a job.
and until the AI can identify how much you can trust an end user based on the first thing they mention while recounting an error, ignore anyone who starts with "i just..." because they for sure KNOW they fucked up, but refuse to tell you WHAT they fucked up, in case that wasn't the issue, and they just admitted to using the laptop as a doorstop but actually it WAS a virus that snapped the machine in half.

Power stations
Generators
Power generation.
No meme no larp.
I just bought a Dabson 2048 over a generator as a power solution for outages.
I did this because I don't know what the future price or access of gas will be. I live rurally and have very little power needs. The most I would need power for is to power a brooder plate or keep a fridge on.
I can cook with propane and wood and I heat my home with wood. I plan on getting a solar panel to charge the power station in the event of weeks or months long power outages.

Is there anything I'm missing or didn't think about or reasons why a power station is dumb? I have had several generators in the past and when you really need them there is always something wrong with it or you gotta go get fuel so I got a power station instead hoping it better serves my needs.

Keep a fridge
Charge a phone
Plug in my fan on my fireplace
Light
That's about all I'd need it for. I got the idea because in the past I used DeWalt batteries attached to an inverter to keep a brooder on during an outage.

Thank you. Do the shade panels solve this? Or is there a gimmick?
I think they are called shade resistant panels?

I appreciate you taking the time on this. I'm not trying to be unrealistic, again, just kinda playing at this point. The Anker c1000 solved my "generator" thing. It runs both my fridge and freezer for 18 hours.
We get rolling blackouts because we live rurally and on old infrastructure and that works fine as a ups.
I didn't know I was looking for a ups till I learned what a ups was.

I'm rambling. Again. Thanks for taking the time to give me a better real world perspective. If you wouldn't mind. Do the shade stopper or shade tolerant panels work? Are they worth it? Is it a gimmick or scam?

I live in a crazy windy and bad weather area. But I live on a hill and get direct sunlight all day. I planned on seeing what wattage I could get if I just hang them off the side of my deck (second story). I get such a greenhouse effect in the winter i don't even start a fire till it's below freezing.
Tldr:
How do you feel about shade resistant panels?

Shade resistant is for an entirely different thing. "Shade resistance" means PARTIAL shading resistance.
If you have a solar panel and you cover up 10% of it, depending on which 10% you cover, you can lose up to 90-100% of its performance. This is due to electrical nerd things but it's just how it is. So the shade resistant panels sort-of solve this problem by changing electrical whatever things inside. This ONLY solves this issue, shade resistant panels do NOT work better in cloudy weather. Only if you have a panel that, say, gets partial shade from a tree during some parts of the day, then the shade resistant one will work better.
>hanging a panel
Since you aim to have very few panels, you should try to get the angle right. Being out of angle again reduces your production. But if you have a lot of space and don't mind getting more panels, then hanging can work (provided the panels are properly secured, I do not mean literally hanging them by a rope).
>how much does angle affect
https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html
Pick your location, enter slope and azimuth, see how it changes numbers. It changes numbers a lot.
>600W panel
It produces proportionally more, but not "in the same space", a 600W panel is invariably bigger than a 400W panel.
>hook 1000W to a thing that can only take 600W max
They usually self-regulate, so you get better output in shaded conditions but in full sun you only get 600W instead of 1000W. But you must match voltage and amp spec of the device.
>>
>>2984111
Got the general gist as I learn more about it.
Yes I saw the units have voltage ranges. Thanks a lot!

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.

>>2983606
you 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.

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.
