A friend of mine just sent me this picture and said someone they knew just got a capybara. I informed them that that definitely isn't a capybara. Now neither of us know what it is. It kinda looks like it's in the uncanny valley of the rabbit species. Is it just a fucked up looking rabbit?

Seriously, what sadist saw a flat PCB surface, flat pick and place machine heads, and said "lets create a round component"?

Joking aside I am genuinely curious what advantage the MELF design actually offers. I know they're a pain to get a machine to place properly, they have more solder flow issues than components with flat leads, and they seem like they would be harder to manufacture too. So why a round component? Anyone here have any insight on why they even exist?

So I just discovered that I have been working next to the waste of oxygen that raped my best friend several years ago. I work in a manufacturing environment and I know that you can't fire someone just for being a sex offender unless it directly interferes with work duties (in the US). But despite it being a primarily male workforce he does work with several women who have no idea what he is. He literally followed a woman home, broke into her house, and raped her. Him working here puts every female employee at risk. How is that not an unsafe working environment? How is it at even legal to employ him anywhere where he will have contact with women?

So I'm planning out a bathroom remodel and part of that is replacing the vent fan because currently mine is just venting into my attic (no bueno). I know normally bathrooms are vented out through the roof but my bathroom is on an exterior wall so I was wondering if I could just vent it out the side of the house. I'm going to be ripping open that wall anyways and I would much rather cut a hole in the side of the house than run a vent pipe up through the roof.

Also I'm in Minnesota if climate is a concern.

I work on equipment that runs off 3 phase 208V but it uses uses a transformer to drop it down to 120V for most of the controls. On this equipment I noticed that there are two fuses on the lines exclusively feeding the 208V side of the transformer and a fuse directly off of the hot side on the 120V side of the transformer.

Isn't the fuse on the 120V side of the transformer redundant? From my understanding, if there is a current spike on the 120V side of the transformer then that will cause a current spike on the 208V side of the transformer and immediately blow those fuses anyways. Is this just a certification thing where that redundancy is required? I'm in the US but this equipment does also get shipped to various overseas locations. Also, while it isn't standard, this equipment is capable of passing a TUV inspection if a customer requests it so I'm not sure if the potentially redundant fuse is just a TUV requirement.

I've been seeing a lot of users from alien.top commenting in various threads (mainly sports) lately. They only caught my attention because they are all flagged as bots and I typically manually block most bots (not all because there are some I like). For every one of them their entire post history consists of 1-2 comments or posts. When I took a look at that instance there is nothing there at all and it also shows no users. The comments look human enough but I guess I wouldn't be surprised to learn that all the comments are LLM generated. Is alien.top just someones LLM experiment or is something else going on here?

So I'm a refrigeration tech with some electronics manufacturing experience. But I've never combined the 2 skillsets so I've been toying with the idea of building a large vapor chamber to cool a computer via direct immersion in a refrigerant. I know its about as far from practical as you can get but it sounds like fun.

Ignoring all of the many many other problems with doing this for now the one thing I'm not sure about is how well the electrolytic caps on the various components would survive. I would need to pull a fairly hard (500 micron) vacuum on everything before I charge it with refrigerant. I know most electolytic caps aren't vacuum rated but I'm not sure if that just means you can't have them operating in a vacuum or if they will immediately pop if you just subject them to hard vaccum period. Additionally while I am planning on using a low pressure refrigerant (probably some R-123 substitute but I'm definitely still working on that part) the components would all still be subject to pressures of up to about 20 PSIG at the high end. Beyond that point I would probably have an active cooling system kick in just for safety sake. I'm not sure how well the caps in particular would survive being immersed in a liquid under 20 PSIG pressure.

Does anyone here have any experience subjecting electrolytic capacitors to hard vacuum or elevated pressure? At what point do they just pop?
