This is a thread to discuss smaller waifu building problems, solutions, proposals and questions that don't warrant a thread. Keep it technical. I'll start.

Liquid battery and cooling in one
Having a single "artificial blood" system for liquid cooling and power storage would eliminate the need for a vulnerable solid state battery, eliminate the need for a separate cooling system, and solve the problem of extending those systems to extremities.
I have heard of flow batteries, you'd just need to use a pair of liquids that's safe enough and not too sensitive to changes in temperature.
This one looks like it fits the bill. The downside is that your waifu would essentially be running on herbicide. (though from what I gather, it's in soluble salt form and thus less dangerous than the usual variety)
https://www.seas.harvard.edu/news/2017/02/long-lasting-flow-battery-could-run-for-more-than-decade-with-minimum-upkeep

How close are we to creating artificial muscles? And what's the second best option?
Muscles are perfect at what they do; they're powerful, compact, efficient, they carry their own weight, they aren't dependent on remote parts of the system, they can be controlled precisely, and they can perform many roles depending on their layout alone.
We could grow actual organic muscles for this purpose already but that's just fucking gross, and you'd need a lot of extra bloat to maintain them.
What we need are strands of whatever that can contract using electrical energy. Piezo does the trick at small scales, but would it be enough to match the real thing? There have been attempts, but nothing concrete so far.
What are some examples of technology that one could currently use instead?

High level and low level intelligence emulation
I've noticed a pattern in programs that emulate other computing hardware.
The first emulators that do the job at acceptable speeds are always the ones that use hacks and shortcuts to get the job done.
It comes down to a tradeoff. Analyzing and recompiling or reinterpreting the code itself on a more abstract level will introduce errors, but it is a magnitude of order more efficient than simulating every part of the circuitry down to each cycle. This is why a relatively high level emulator of a 6th gen video game console has close system requirements to a cycle-accurate emulator of the SNES.
Now, I want to present an analogy here. If training neural networks for every damn thing and trying to blindly replicate an organic system is akin to accurately emulating every logic gate in a circuit, what are some shortcuts we could take?
It is commonly repeated that a human brain has immense computing power, but this assumption is based just on the amount of neurons observed, and it's likely that most of them probably have nothing to do with intelligence or consciousness. If we trim those, the estimated computing power would drop to a more reasonable level. In addition, our computers just aren't built for doing things like neural systems do. They're better at some things, and worse at others. If we can do something in a digital way instead of trying to simulate an analog circuit doing the same thing, that's more computing power that we could save, possibly bridging the gap way earlier than we expected to.
The most obvious way to handle this would be doing as many mundane processing and hardware control tasks as possible in an optimized, digital way, and then using a GPU or another kind of circuit altogether to handle the magical "frontal lobe" part, so to speak.

>>22032 >fibergrid That has got to be one of the most brilliant ideas ever. You could use a cheap ESP32 CAM Camera Module Kit. They sell them with cameras on them already for $10 USD. Then you have up to 1622×1200 sensor channels. WOW! what a great idea. Do them in a sort of X'Y' grid and then you have what part of a finger and how far up. You could use this for position sensors also. Have a rotating bump or wheel press on an array of fibers. So with a little work you could have every single touch sensor and position sensor in one $10 camera. Some ideas are so good they are just...stupendous and this is one.

>>14738 kek, feel free to email the libcaptcha author (kefeer@brokestream.com). that library has some problems indeed, I noticed that various things were wrong when I used it for the ib, I even felt tempted to rewrite it entirely, or at least partly, or at the very least fix the compiler warnings, but got scared by the copyright notice (points 1 and 2 in particular). and didn't want to waste time writing my own. I ended up doing things like avoiding the gifSize "constant" entirely and the declare my own ("constexpr int gifSize = 17646"; constexpr is a C++ specifier for expressions that are known at compile time). to avoid some of the semantic problems that you mention. you're wrong about the internal linking tho. g++ uses internal linking by default for symbols marked as "const" (and static, obviously). I never #include the libcaptcha.c file, so the compiler would throw an error (even before linking) if I tried to use those symbols anyway. the C++ part (my code) is even worse. from the hard-coded queries to the obscure orm (which needs it's own compiler to generate implementation files), blocking queries everywhere, and non-threadsafe globals in a multi-threading context. it nonetheless work. I might try to write something better in zig or C++ in the distant future

Realized I was being kinda silly devising my own convoluted logging system out of concern for performance latency, once it suddenly dawned on me the C++ standard library already sported a perfectly-serviceable buffered logging system--which can lazily write to files. Here's a little RAII-compliant hack for doing just that. [1]

#include <cstdlib>
#include <fstream>
#include <iostream>
#include <string>

class File_clog {
 public:
  File_clog() = delete;  // no default ctor

  // globally-redirects all std::clog output into the given filename instead
  File_clog(std::string const& name) : log_nm{name}, log_file{log_nm} {
    // assign this log file's buffer into std::clog:
    auto log_buff = log_file.rdbuf();
    std::clog.rdbuf(log_buff);
  }

Stop. Congratulations Anon, you've finished with chapter 11; and in fact with a couple of very detailed chapters loaded with information. C++ I/O streams are a bit tricky to master at first, but they are an exceptionally powerful and (nearly-always) elegant approach to I/O management in general.

Kiwi here to teach fellow Anons. First is how to make a ball and socket that pop together with side guides. These guides turn it into a universal joint. You can incorporate this design into many different other designs, I recommend using petroleum jelly to smooth out the motion. For reference, the ball is a 12 mm sphere. The socket has an internal 13 mm sphere and the mm difference is necessary at all scales. More tutorials will come. All information is freely given for the sake of catgrill meidos.

>>23299 >You're specifically talking about something like foamcrete... No I'm not.You are throwing up straw Men that are not what I'm talking about. >You admit there's better materials The best material is that which is cheapest which will do the job you want. I'm not interested in building Olympic athlete level bone. Look I just asked some questions about a sort of glue on an off chance that someone would know how to proceed with a more basic activated waterproof formaldehyde glue. It's a odd thing but someone might happen to have an answer to this. I did give a patent reference of just such a thing. You keep telling me I must do it this way or that way but I'm telling you that there have been different ways that are not your way and that your way is not what I'm talking about. The bottom line is that there are huge advantages in cost and manufacturing if you could pour concrete into molds to make a whole skeleton or many of them at once. Fiberglass, carbon fiber, etc. requires either hand lay up, vacuum resin infusion or machinery that pressurizes the resin into the mold. All these requiring either a lot of hand labor. expensive consumables in the case of resin infusion or expensive machinery. I don't want to talk about this anymore because we're not talking about the same thing and I don't want to talk about concrete for hours.

It just came to me. I;ve been barking up the wrong tree. https://en.wikipedia.org/wiki/Moisture_cure_polyurethane Gorilla glue. Gorilla glue is waterproof, expands so it would coat good. https://www.gorillatough.com/product/original-gorilla-glue/ If you graded the concrete aggregate so that all spaces were very small you could likely have a very strong material. The Army did a study on concrete and that is how you make high strength concrete. This is why I write such weird stuff at times. Somehow writing this stuff down sometimes creates odd connections. I have no idea why I did not see this before. Of course it may not set in the extremely alkaline conditions of concrete. I'll have to find out. BTW way I have a folder on concrete and it's over 4GB in size on papers and books on concrete. Not that I've read every bit of it but I've seen a good bit. I really like concrete. It's an amazing material. Here's one paper with a mix for Ultra High Performance Concrete Development of Non-Proprietary Ultra-High Performance Concrete for Use in The Highway Bridge Sector 13100

After looking further. Too much water. Likely not work for gorilla glue but...will look more.

>>23303 Do you even know what a strawman is? I said foamcrete because it's actually the product you're looking for, not because I want to argue about it. You set up your concrete mold, get the chairs for your mesh or rod support, put the chairs under it, pour your mix, vibrate it until it's settled ,wait until the concrete begins to set, remove the chairs, set the skeleton back in, shake it again... You're doing a lot of hand work any way. I'm not telling you what you're going to do, I'm telling you what the properties of the material you are talking about will *allow* you to do. Considering I haven't actually told you to do anything, I've only offered some practical advice, I'll follow up with more advice. By all means please use concrete for diameters less than an inch because you're not worried about Olympic athlete level bones, I'm sure your books and folders on concrete will help you realise why it won't pass any stress tests.

>>23313 >Do you even know what a strawman is? Yeah it's an idea that someone proffers that is sure not to work so that they tell someone what they are doing is wrong. Like, >I said foamcrete because it's actually the product you're looking for... then you say, > I'm sure your books and folders on concrete will help you realise why it won't pass any stress tests. So yeah I'm fairly confident that what you're doing here is propping up a straw man. >I've only offered some practical advice Practical? I don't need any advice from people who tell me to use foamcrete for waifu bones. You don't know what I'm talking about. The question I asked was fairly narrow and likely very few people would know the answer. I only asked because...you never know. Someone might know the answer. Those that did would understand the references I gave. You did not. Hence your telling me about foamcrete and totally misunderstanding.

>>19469 >Sorry, but your idea is completely twisted. Lol. Fair enough. :^) Neuralink is here today, by all accounts. Surely they are still well-off from their general long-term goals, but there's little doubt they are outstripping robowaifu industry developments for the moment. And, I might add, that's little surprise tbh. The Robowaifu Age is a vastly bigger, vastly more-complex set of problems to solve, than just the 'general neural implants' cyber-age. BTW, thanks for bringing up your highly-interesting topic here on /robowaifu/, Anon. We'll actually see it happen I'm sure. >=== -prose edit

>>19470 >Neuralink is here today, by all accounts. Hmm, okay, but then who has it? TITS was basically about text commands, we already had that many years ago. That aside, most of the tech would run on the side of the user, and it's (somewhat) available. Dependent on the variant the operators would require Whisper or some other speech recognition. Neuralink requires some operation if I'm not mistaken. I don't know about the release of some full human behavioral model using it, and I doubt very much it is possible anytime soon. Controlling devices is not the same.

>>19471 >Hmm, okay, but then who has it? The rumor as I understood it was that several hundred actually queued up and paid large sums to be the first ones. >Neuralink requires some operation if I'm not mistaken. Yes, it's a extremely-technical surgical implant into the brain. Also, about the TITS robowaifus, since you're here now, maybe we can continue the discussion in that thread about the technical aspects of the design ideas. That thread has languished for a while now, maybe it's time to pick it back up? Regardless, thanks for all the inputs Anon. These are some fascinating concepts involved with these implant systems.

>>19472 >maybe we can continue the discussion in that thread about the technical aspects of the design ideas. I was concerned that this is where this would be going. Thanks, but no. Not right now. I need to get back to 3D design. Reading through the MaidCom thread and some afk stuff already distracted me for too long. I generally decided at some point that I would first need some animated body, before I work on AI or AI plus remote input. I can't jump back and forth, because of mental occupation. I might need to do some traveling soon, and might pick it up then. Maybe I also find some old notes of mine when I finally sort out my files and backups.

>>19473 Understood. Good luck and looking forward to your progress Anon! Cheers.
