I swear, every Ford Econoline is just powerfully cursed. This one sharted out its coolant somewhere on the passenger side. Good times waiting for the tow truck, at least it’s a nice cool day so far with no heavy smoke.
Fuses are wonderful electrical protective devices. They work till they don’t, and in the case of glass cartridge fuses, looking at the remains when they blow can give you some insight into what happened at the moment of fault (prolonged overload, dead short, slow overheating, etc).
Or in this case, uh, what
Today’s contestant: a 1.25 amp with some delay characteristic out of a switching power supply in a bookshelf stereo.
One look at this told me there was no need to fear a big nasty fault with the power supply. It went out very, very gently, in fact, STRANGELY so.
If you see the element slumped, that indicates it was running hot a while.
The element blowing up and becoming silvered to the glass indicates a high current fault. Often that’s a shorted rectifier bridge or caps when it happens on a switching supply.
What follows is an attempt to get a photo of this under the microscope.
VERY unusual. Note that the fuse wire itself looks perfectly fine and the fault looks like it occurred without any serious heat.
I really just don’t get it. My best guess is the fuse wire actually cracked instead of melting, possibly due to long term thermal cycling or vibration.
The alloy bead is a heat sinking feature to give the fuse element a time delay curve. As heat builds up on the fine wire it will be absorbed through the connections to the end caps and to this blob. Once it gets the blob hot, the delay time ends and a sustained overload will melt the element. Of course, a high current fault can always blow the element to slag in a very quick instant.
See, this all makes sense, right? Here’s something that doesn’t… a CrapTrex Freedom SW unloading undocumented fault codes like a bag of soda cans at the recycling center.
Yeah now I’ve done it
And now, some fairly dank memes:
And now, back to cats and electronics as usual.
I’m pretty good with paint and watercolor, in general, though I haven’t been doing it enough in the past few years.
Hair is confusing as hell.
Some pigments want to take better than others, and with my hair, well, it’s inherently evil and doesn’t want to listen to any chemical intervention. Somehow it seems like pink and red work better than anything, which is fine by me because I love how pink looks in there.
The new colors are florescent…
Surprisingly, a standard blue LED sets it glowing better than this UV penlight that was made for detecting a/c leaks.
I must be the most colorful engineer out there nowadays
Turns out I finally found a way to enjoy the wonders of THC without it totally knocking me out. The magic seemed to be a tincture mixed into strong iced coffee. Sure, why not. Wonder if anyone’s ever tried that with Cuban coffee? It’d probably break the universe.
High thought #1:
I’m gonna start at least internally calling that specific kind of crazy logic-resistant insanity that’s all the rage “Chicken and Stars”.
High thought #2:
This picture of Cassie makes her look a lot like a super happy friendly cat in a Miyazaki world.
I mean just look at this face.
Look at it.
Also I generated this look alike in the e-girl doll maker.
I need more short skirts and fishnets in my life. I’m so divided though because long dresses look so awesome on me.
Current weather is too hot for the delightful shiny PVC looks. Come on fall
I figured out an important piece of cat logic today: the tail pops out once she’s full
Getting ready to launch!
Gingy is getting really affectionate lately and asking me to pet her… Always. She’s following me around again, isn’t she? I had also called her Sandy Beach in another post which is very cute and she seems to answer to that too.
As I walked into the core to figure out why I was observing what I thought was an unwarranted audio delay, and went to have some words with the Optimod 8685, it occurred to me I have no idea what my hair looks like from the back so I took an action shot of this vital conversation with said machine and it was grand.
It’ll be even more grand soon.
I added more disk space and removed old junk on this virtual server so it’s no longer constantly trying to run out of space and hit the wall screaming and stuff
To celebrate here is some nonsense
everything’s all updated and happy and fresh on the server now but oh no i got the wordpress block editor because i forgot to re-enable the classic editor plugin thanks i hate it
also I apparently get enough traffic or something that if I turn off akismet I get big flowery comment spam at a rate of about 0.2 hz, WOW!!! they like me! they really really like me—- or something
“you put the audio deembedders WHERE?”
..or, “how I immediately came to love platform boots”.
And for no particular reason:
