I no longer wish to make money off this idea, I simply want it to exist

Ship mirrors with built in liquid crystal layers that use the camera in the car to map and then block headlight brightness from the driver.

It takes some electricity but the car has batteries and an alternator.

Anyone other than Tesla or a Elon musk invested entity is allowed to use this idea.

Well, auto-dimming rear-view mirrors have been a thing since the 90's.

Your idea layers onto that, and I'm sure it would require trivial amounts of power (watches have used LCD since the 80's).

I'm pretty sure I've seen LCD used as a dimming method for windows.

Those things fucking suck! Last card I had had one and it took like 30 seconds to a minute to darken. Next car I made sure had the old school flicky doohickey.

[-] panda_abyss@lemmy.ca 2 points 9 hours ago

Yeah, but the window ones require a lot more power hear. No idea how the physics and math work out.

I think you speak of a feature that some BMWs have where they have a led matrix for headlights and will selectively turn off the ones aimed at oncoming cars while the rest stay on

But I want this defensively, for the car with LEDs installed at old incandescent voltages, the truck that rides 3" from your bumper, and the guy who got replacement bulbs at a cheap garage who didn't adjust them correctly.

BMWs divert all power from turn signals to the LED headlights.

[-] Rhaedas@fedia.io 1 points 2 hours ago

This is not true.

BMWs do not have turn signals.

Re-route power to the shields, emit a tachyon pulse through the deflector, and post all the nonsense you want. Within reason of course.

~ 1. No bigotry. This is a Star Trek community. Remember that diversity and coexistence are Star Trek values. Any post/comments that are racist, anti-LGBT, or generally "othering" of a group will result in removal/ban.

~ 2. Keep it civil. Disagreements will happen both on lore and preferences. That's okay! Just don't let it make you forget that the person you are talking to is also a person.

~ 3. Use spoiler tags. Use spoiler tags in comments, and NSFW checkbox for posts.
This applies to any episodes that have dropped within 3 months prior of your posting. After that it's free game.

~ 4. Keep it Trek related. This one is kind of a gimme but keep as on topic as possible.

~ 5. Keep posts to a limit. We all love Star Trek stuff but 3-4 posts in an hour is plenty enough.

~ 6. Try to not repost. Mistakes happen, we get it! But try to not repost anything from within the past 1-2 months.

~ 7. No General AI Art. Posts of simple AI art do not 'inspire jamaharon'

Fun will now commence.
