What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Tin in solder or some other meals can form spiky crystals when under stress. These whiskers can form short circuits if not properly insulated or not alloyed with other metals.

Hey, tin whiskers! I haven't seen this happen in person since my Jerry rigged Celeron 333A killed itself. I'd created a monstrous homebrew cooler with raw bar stock aluminum as an IHS with a big fat peltier cooler and a huge heatsink so I could run the thing at 550mhz. The aluminum eventually grew a tin whisker after the machine had been running in my closet for a good 4 or so years and shorted the Celeron carrier board.

Apparently this was a pretty big problem in aerospace back in the early days, their electronics were particularly prone to this failure mode.

I'm not as tech minded as others on this platform. I think you said you were building a space ship in your closet that grew whiskers, and comitted suicide.

That seems like the kind of thing Disney would make an animated film about in the 60s. A child sized rocket thats grown depressed. So instead of flying to space with a kid inside, it instead goes into the closet for so long that it grows whiskers, and then ends it all.

It would be like that scene where bambis mom dies. It's ONLY there to traumatize kids, and punish parents who now have to deal with a crying kid.

Because Disney is evil.
