Found this just sitting in the corner in the attic of my 1926 house. No idea what it is. When you turn it over it sounds like there is liquid in there. Any ideas? Can I just pitch it?

Yes but with the coil, he may be on to something. It could be some sort of matching coil for Shortwave/Amateur Radio/Police/Fire/AM/FM

People still make these diy/commercial

Also it could be a little heater thing but it cant get too hot because it would melt the solder connections. But also looks like a mica sheet insulator. Maybe low heat to keep condensation out of attic?

having trouble with electrical, outlet has enough charge to shock when i touch it but not enough to power a light bulb, I tried the light bulb in other sockets and it is fine. it is a gfci outlet at the end of the run.
i get shocked but there is not enough umph to light a light bulb.
can someone go over basic sparky trouble shooting techniques with me.

> Bad neutral connection.
This.

Neutral is tied to earth, and you're weakly tied to earth by capacitative coupling. This is why those testers (the ones which you poke into the live hole and touch the top) work.

But without an actual neutral connection, the current is in milliamps, maybe even microamps.

I reworked almost all my house wiring myself, and got zapped dozens of times. It's just a tingly feel
Sure I get being careful especially when you are in a narrow space and wear rubber shoes, but it's not industrial voltage

I found a deal on 4000 watts of solar panels for $400 but they are high voltage like 200 volts per panel. Am I correct to assume these are not suitable for DIY off grid projects?

True if simple 12 or 24V off grid system. Hybrid inverter chargers can handle (and also use) the extra voltage. They are 10 times as expensive but then delicious AC. Vevor has a cheap one.
>>
>>2977448
Well if the op wants to cheap out on spending $600 on a box i think there is a way to diy it and it could end up being cheaper if hes willing to put in the time. There are some things that are not practical to diy sure. Like soldering ram or making a fancy radio duplex transmitter or more complex circuits but this does not strike me as one of those things. Idk theres metal transformers from microwaves that have good iron cores though those are a bit scary and need to be discharged.

Depends on the "box"

Cheap pwm charge controllers do what it says on the box. Run pwm to reduce panel voltage down to whatever voltage is needed for charging the battery. They may have some simple charge logic or may just a be a dumb "Here's 13.6v, enjoy". They are terribly inefficient and don't work if panel voltage drops below what you want out.

Mppt use either a buck converter, or buck boost converter and a bunch of microelectronics to shift around voltage and current input vs output to match the panel as it's power output changes due to clouds, time of day, shade, etc.

An inverter was also mentioned, in which case the, typically mppt, charge controller also has a DC to AC inverter tacked on, giving out whatever your country's flavor of power.

Mind you, for any real power we are talking 150+ volt systems, can easily be 400, 800, or even 1000 volts. Not very diy friendly. On the other end, a small 24v or 48v system with a couple 100 watt panels can prolly make a diy controller feasible, but once again, a low voltage system of any real power will be passing around 100+amps. Not diy friendly.

So no, unless all you want is a small pwm system to run a couple lights, you are not realistically going to diy anything to do with the "boxes"

You get friction issues. And if something can penetrate one it can probably penetrate two.

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.

If LLMs like ChatGPT, Gemini, and Claude can be used for vibecoding, then shouldn't it be possible to use them to generate a netlist for use in a SPICE program (LTSpice, NGSpice, PSpice, etc.)? I've never tried it myself, but I have seen people make subcircuits for LTSpice to simulate AC and DC motors, so I think simulating a BLDC motor driver shouldn't be an impossible feat.

Didn't you watch the movie Dune? "The spice must flow".
Just kidding. SPICE is an electronic circuit simulator, widely regarded as the industry and academia standard for circuit simulation. It was originally developed by an EE professor named Laurence Nagel at UC Berkeley in 1973. Since then, many variants of SPICE, both FOSS (NGSpice), free but closed source (LTSpice, Q-Spice, TINA-TI), and paid (PSpice) have popped up.
Both KiCad and Tinkercad's circuit simulation modes rely on NGSpice. Tinkercad has the disadvantage of not allowing custom component models to be imported, but stand-alone installations of NGSpice will allow you make them, so as to include, say, a custom transistor with specific beta values.

I remember getting free student versions of TINA-TI and PSpice using my university e-mail address, but I'm not really sure how easy it is to get a hobbyist version of them. LTSpice is absolutely free, but it doesn't have component models for electrical motors, even though some people have made their own in the past.
https://www.precisionmicrodrives.com/ab-025
LTSpice is Windows-only, however. Fortunately, NGSpice will run on Windows, Mac OS X, and Linux, although it may be slightly more difficult to use, as it doesn't come with a waveform viewer by default, so you'll have to use something like GNU Octave or Matplotlib to graph the waveforms. Fortunately, KiCad and Qucs-S (which both make use of NGSpice) do have their own built-in waveform viewer.

The biggest advantage of using any SPICE tool is knowing that you'll have a netlist (in order words, a structured list of nodes and components) that can be edited as a stand-alone text file, which makes it very easy to use custom components and group together components into subcircuits. Since it's text-based, I don't really see it too difficult to imagine that something like ChatGPT or Claude could at least write a custom netlist for a relatively simple circuit.
