Rather ancient technique - really long lifetime, extreme brightness, but it is pretty much black'n'white only - either it shines or not. not worth buying imo.
uv is used also to find if some foods are edible or not. peanuts, for example, can have some bacteria that produce tetrodoxin, a chemical very poisonous (epatotoxic), but also very reactive to UV
uv light is also commonly used in the pet industry. uv sterilizers are used in fish tanks to control unwanted algae . and certain reptiles need uv lamps for calcium and bone health.
One important thing you missed about UV light: It causes white plastic to become... yellow. Yuck! That yellow old computer is only yellow because of UV light. Protect your pretty white plastic by avoiding UV in the room: shield your windows with UV-blocking film; replace your regular incandescent light bulbs and fluorescent lamps (CFL too) with LEDs.
That toothbrush thing really confused me. First I thought it was an advert, then I remembered the UV light thing so assumed it was related, then it turned out it was the UV light thing so I settled on it being a part of the video, but then it just turned into a normal LTT/TQ advert.
I use to print on plastic containers. Yogurts, sour cream and such. The container would spin past the UV light and instantly dry the ink at around 300 to 600 cups per minute.
UV is also a stimulant, a cyan color, which is why it keeps people awake at night while staring at their "blue" screened phone. The newer iOS has a night-mode that makes the image warmer "yellow-red-ish" which is a calming color that helps you go to sleep at night. :)
Last time I got sunburnt was absolute hell. My skin itched like crazy for about 3 days straight. Could not resist scratching, felt like ants under my skin. Never been so irritated in my life.
The internet can be used for so many amazing things. And here you are using it to inform people who don't care that you are early on a fucking youtube video. What a waste.
Do an episode of fast as possible on CDs and DVDs. Why are there only 90 minutes of playing time, but 700 MB of storage.. whats the difference? And why cant i have a 5 hour long cd that takes up 690 MB? I REALLY wanna know this and i am too lazy to google it XD
DrToonhattan Thats not how it works when it comes to Music cds, sadly enough... because if you ever had to burn down songs on a cd to have in your car or stereo, then you have to make a MUSIC disc, otherwise it wont work. And music discs are limited by TIME while Data discs are limited by the amount of MB it has. And that is what i wanna know, why we cant have a fully loaded 700 mb music discs that works in the car or stereos. Do you get what im saying? :)
Ah I didn't quite read your question right. I'm not entirely sure about this, but I think that a car stereo or other stand alone CD player is only able to read disks at a specific bit rate and file format. That would make sense I suppose.
They often use UV dye in products in order to make them look brighter. Whether that be modern white plastics or neon yellow post it notes. The reason they look so bright is because of UV light.
I feel like techquickie videos became JUST ads. That's it. No content, just ads. It's got nothing to do with computers/phones/usual tech they cover. They got sponsored by Taoclean, so they just made a video on how it works, to get MORE money from the sponsor... Nothing to do with regular channel and regular tech content. Honestly, this bothers me... I was cool with all the ads at the end of the videos, but at least those videos were relevant, unlike this 1. This feels like "the more you know" type of channel, rather than a tech channel.
Adrian Howard-Larsen The WHOLE video was made, just for the sake of AD. Just so it was 'connected' somehow. UV Light... Nothing to do with gamers/tech they usually cover... But just for the sake of UV Light cleaning toothbrush...
sharks445 Are you that oblivious? Really? The whole thing was made for the ad. They have no freakin idea about IC chips. They use them, they' DON'T talk about them in their videos. They do phones (a bit), pc peripherals, pc parts, servers, networking and that's it. Check out LTT if you don't know what I mean. If it isn't obvious to you, that this was made as an ad video, then I've got nothing else to say to you.
