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.

David Misell, an English inventor, invented the first flashlight and patented it in 1899. It used three D batteries in a tube that was used as the handle of the device. The batteries supplied enough power to create light through an incandescent bulb.

The name “flash” light was a knock on the reliability of the model. These units could not be left on for long because of the zinc-carbon batteries that couldn’t hold an electrical current for long periods of time, thus creating only a “flash” of light.

These early flashlights were nothing more than a novelty at the time. The batteries were inefficient, and the bulbs were dull. Improvements of the batteries and bulbs by Eveready and others started to increase the popularity of flashlights by the second decade of the 1900s.

I just call it a torch, which I think is etymologically related to the flaming things.

Related fun fact: The "Fleshlight" got it's name because it kind of looks like one of those things mentioned above!

Not if you don't want bacteria or mold to grow in it.

The thing I was surprised to learn was the D batteries were a thing back then.

[–] Ghoti_@lemmy.world 13 points 1 year ago

You’d be surprised at how much old technology is still used in parts of our electrical devices and electronics

The other kind of flashlight also takes the D

[–] emogu@lemmy.world 2 points 1 year ago

TIL ops mom is a flashlight

[–] WhoRoger@lemmy.world 6 points 1 year ago

Even AA batteries have been around for about a century now, and I think even button cells like CR2032 have been around since the 60's. These standards are ancient.

[–] sab@kbin.social 6 points 1 year ago

According to Wikipedia it was introduced in 1898, so the flashlight was invented almost immediately after. I guess it's the natural next step when you have light bulbs and batteries.

the second decade of the 1900s

The 1900s were a decade. It also takes longer to say that than "the 1910s".
