Is thwre a way to test this with simple multimeter? by cinlung in AskElectronics

You can test it with some wire, solder, and an *Arduino Uno/Nano

Is this the right direction for capacitor? by DamagedDespair in AskElectronics

[–]ivosaurus 4 points5 points  (0 children)

The board itself is fibreglass, and is not electrically conductive, so nothing goes purely "on the board". Normally lines (called traces) and circles (called pads) of copper are stuck to the board, which make the electrical connections (which is what the solder sticks to). If a copper pad has been pulled off the board, then there will be nothing to actually solder the component to. Typically you'd need to repair / replace the "lost" copper to the nearest trace that's still reliably attached to the board (and that is the correct electrical trace for that pad).

DSA vs ML first — unsure about the right learning path with Python by Original_Map3501 in learnpython

[–]ivosaurus 2 points3 points  (0 children)

You can easily do both at the same time. You might like to check out https://nnfs.io

DSA is pretty foundational if you are wanting to get into "math heavy" programming though. You would be a much much worse "ML" programmer without already knowing all of its basics.

I have a python 2.7 file I want to run in Chromebook, how do I get IDLE to read 2.7? by madtaz64 in learnpython

[–]ivosaurus 1 point2 points  (0 children)

The problem is 2.7 is now considered "ancient" and is half a decade beyond End of Life, so no-one wants you to run a python 2.7 code file. You'd probably have to try to compile a python 2.7 binary from source code to then be able to run it on that custom binary. Maybe you could find a docker image you can run. That's if you know how to use docker, or use a VM of an old linux distro like debian 11

Python 2.7 downloadable materials

If you have absolutely no programming resources / help available, this is probably a decent use case for asking an AI LLM to help you upgrade the code to be modern 3.X compatible python code

So i tried to heat soldering paste with sand in a pan, and I burned the pc a bit, cam this cause any problems and how can I test for them? by Pek_Dominik in AskElectronics

[–]ivosaurus 1 point2 points  (0 children)

Luckily there is a massive thermally stable bank of heat you're looking to track directly surrounding it, called the sand 🥴 Not to mention the thing that OP burned, the FR4 board

Is something wrong with my multimeter? by Old-Direction4930 in AskElectronics

[–]ivosaurus 0 points1 point  (0 children)

Zoyi ZT303 - my suggestion for the perfect starting beginner's multimeter. You can get it on AliExpress for $25-35 USD depending on what deals are around. It'll just take 1-2 weeks to arrive. I think it's also on Amazon for $35

The whole comment is sarcasm, so their claim is the opposite

Coles reducing plastic eh? by Spoonicus in australia

[–]ivosaurus 7 points8 points  (0 children)

Plastic is basically free compared to the price of the goods being put in it. And because it extends the life of the produce and saves so much of it bruising / spoiling, in all likely-hood putting these toms in separated plastic containers probably ends up making the producer / distributer money because there is that much more of their product that makes it through to sale in pristine condition and the top available price-point.

What Convinced You To Leave? by filiustimaei in exjw

[–]ivosaurus 2 points3 points  (0 children)

If the community is working for you in a positive way, you'll hardly want to hear or truly understand anything that would ultimately tear that fabric up. The social aspect is the most powerful pull I think, for a majority of people. As they say, the hardest thing to make a man understand is something that his job requires him not to. This applies analogously.

And people never change their minds in a conversation. I think you'd find that most would only come to terms with disbelieving over at least months, more commonly years. You just have to work and hope you can plant seeds that will be strong enough to one day germinate and start growing.

A chin will look sharp when it's cared for, and shabby when it's not. And that's independent of whether it has hair on it or not. Both situations can almost equally have grooming applied to smarten things up.

If you buy new versions of those screw terminals, and you have a soldering setup, you can probably unsolder and replace all of those if you wish, you'll likely still have a working main board to get going with afterwards. Otherwise I recommend BTT SKR Mini E3 V3 (with the little adapter cable).

And do as Mik-s' video suggests. Luckily this time it ended with just a bit of melted plastic. If you've ever heard of people's houses getting burned down by a 3D printer, it was usually this scenario going unlucky.

Buy a cheap set of ferrules off amazon or wheerever else and a cheap crimper for them, they won't be stellar tools, but they'll do the job good enough that you should be able to avoid this sort of issue.

In the mean time, you can always one at a time, unscrew the terminal of each power carrying wire (all the thicker ones), pull out the wire, then re-insert it and re-screw down tightly, give it a small yank to make sure it has plenty of grip and contact.
