Pictures, or it didn't happen.

Trust, I'd wish it to be a bad dream. That thing really had us all worried for a full 48hrs. Wife was out of herself, making me feel like a murderer.
This badboy poo like a bunny and hard as bricks, the part was showing 4 meter away when I got in the garage.
Here's the same cap all brushed up after recovery. Not a single dent, go figure

Have you re-measured the component after its adventure and cleaning?

Did I really just posted a pic of my dog's ass?? lmao. Sorry about that, guys. Damn, got to get back to work....

These caps are suddenly not cool. Had one trying to murder me 6 months ago. Had a 16V on a 24V rail (careless mistake) and it exploded like a nuke 2 feet away from my face.
Still picking up its paper internal here and there still today. Then boom, the dog thinks it's a treat and throat it down like a pcs of cheese.
We're haunted by the Evil Caps it seems

Hope y'all had a good laugh with this canine eeAdventure. I certainly did, in a way!

But on a serious note, it reminds me about the extreme & real dangers of young children swallowing those 'Button' batteries??
THEY seem to be perfectly sealed, and should just pass through, so I don't understand about 'Chemical Leaks' etc ???  :P
Intestines are conductive and short the battery. That produces both electric current and induces chemical reactions, both leading to necrosis.

See the attached photo. That’s a hot dog sausage(1), which had a CR2032 inserted into it for 3 hours, though noticeable damage was already present after the first hour. That is due to electric current alone: no leak from the battery and no heat damage (everything was sitting below 22°C in 24°C ambient).

A hot dog sausage is not representing human body well,(citation needed) but I the picture is giving the right idea about the kind of damage you may expect in esophagus and intestines.

I used to allow our cats in the lab until one day one of those capacitors exploded quite next to one of them. I also don't allow them in the kitchen while I'm cooking. Lab and kitchen are dangerous places.

I didn't even notice until you pointed it out. Now I can't un-see it! Thanks for that.

Give him a diode to swallow too.
That should rectify the problem.

Like Civet cat coffee - this cap was organically selected for low ESR - effective stomach resistance

Being eaten by a dog was definitely not covered on the Adventures of Tanty Bead series:

That is due to electric current alone: no leak from the battery and no heat damage (everything was sitting below 22°C in 24°C ambient).
Well, there is very little damage in the esophagus because it spends less than a second in it, before sliding into the stomach.

In the stomach, the damage is repaired within a couple of days, because the lining is continuously renewed.  (The acid in it does much, much worse damage to a hot dog sausage, too. ;D)

Within the intestines, the damage is spread out over the entire length, and there is a combined mucus and bacterial covering that will take the majority of the damage.

So, although I agree with the damage, human (mammal) digestive systems are quite robust, and deal with damage (as long as the item moves along smoothly).  Having the CR2032 lodged in would be very dangerous, though!



In the doggo's case, the charge in the cap is of course neglible, and would have been discharged in the stomach (where any slight damage would be completely irrelevant due to the lining continuously renewing due to the very acidic conditions).  (If it had discharged in the doggos mouth, we'd know.)
Chemical toxicity and having the cap lodge in somewhere were my main worries; but since it turned out quickly and intact (with almost the original capacitance, indicating there couldn't have much loss of electrolyte or structural integrity in my opinion), I'm happy that the doggo will be absolutely OK.

Unfortunately emergency room disagrees. Coin cells are getting stuck in both esophagus and intestines. The relevant photos are available on the web: I skipped attaching them to avoid both pointless posting of disturbing content and potential copyright issues.

An adult esophagus at rest is big enough to accomodate a CR2032 cell (it is 20–25mm in diameter). But that is not true for children. Neither is when muscles contract, or the walls are inflammed or are not smooth.

True. I did mean that if it does not get stuck, the damage is dealt with.  But when it gets stuck in one spot, it's very dangerous, definitely surgery time.

So many Ingestive integration  cycles have since  passed. I'm sure he's been charged up  with soft food lowering the digestive impedance. Has the pooch in question been properly discharged?

I'm a dog lover.  I need to know.

Seriously, How is your Dog?

EDIT:

Never mind, I refreshed the bow wowser window and the full thread showed up.

Glad your dog is fine.

It would have been very interesting to watch the dog if it had swallowed an inductor at the same time.

I am trying to imagine an oscillating dog... hmmm.

I do believe the oscillating part is called a 'tail', the pulse-avalanche part a 'bark', and the coil/capacitor noise either a 'howl' or a 'whine', depending on whether loneliness or treats are involved.

What's his current ESR? Charge him up.

Stomach acid will be strong enough to dissolve aluminium.
The rest of the digestive tract is not equipped to dissolve aluminium AFAIK.

Aluminium is thought to cause Parkinsons disease.
In the middle ages some rich people started using aluminium cutlery and they all got Parkinsons disease.

Aluminium was first isolated in 1824 by Hans Christian Ørsted. How could people have used the metal in the middle ages?
