I am 76 and don't have a parent at home but I will give it a try anyway. Very good video. 🙂
survived ?
Wow!
LED causes a lot of health issues. The flickering that is not easily observed causes headaches, anxiety and contributes to cataract. Id rather stay with incandescent light. Save on energy cost pay with your life… doesn’t seem like a fair trade.
Yes! Agreed 100% why does no one talk about this!
I also agree, but I can't find incandescent lightbulbs anymore as I sit next to stupid flickering LED lights...
@@alessandrorossi1294make you own! 😉
Now could you use a Baghdad battery to power that?
If they were better the government wouldn't have to mandate them.
You don't get Vit D from LED lights.
@@mamba0465 That's true. LED bulbs have a VERY limited spectrum and don't color render correctly at all.
Super awesome experiment. I will try this for my STEm Camp 2021. Thanks a ton.
Can I still try this without parental supervision? I'm 36
LED are polluant and very unhealthy. If they use "less" energy (to light your room... not to produce them) it is just because it is flickering! The rate is high enough for your eyes not to see it, but it is always getting ON and OFF.... which is very unnatural and a good way to get sick.
Do you feel as if you have a "v1ru5"??
Turn these LED lights off... and see if you're better.
Not sufficient?
Turn the computer/TV screen off (or adjust or filter the blue part at around 25%).
And, if you still feel dizzy... turn your phone off too.
Have a nice life!
Agreed. Some one else commented this as well. The general public is unaware of the effects of led light on the eyes. thanks for your comment!!
OMG, it's so much better! But, I changed over to Maxlite's new LED bulbs that are completely flicker-free! Awesome!!
Amazing little experiment. I`m going to make sure to use it in my science classroom:) Thank you so much.
i know Im randomly asking but does someone know a method to log back into an instagram account??
I was stupid forgot the account password. I would love any help you can give me.
@Phoenix Trent Instablaster :)
@Dakota Jad i really appreciate your reply. I got to the site thru google and im trying it out now.
Takes a while so I will get back to you later with my results.
@Dakota Jad it did the trick and I actually got access to my account again. Im so happy!
Thank you so much you saved my ass :D
@Phoenix Trent No problem xD
The last part is propaganda but I like the DIY explanation. LEDs are toxic
Is that some kinda flat earth type meme?
@Gray Au You do realize that modern LEDs come in all different colors from the full spectrum of visible light? There are already LEDs that match the light spectrum of incandescent perfectly, but at much lower power consumption. The problem was in old crappy LEDs that put out too much blue light, which messes with the circadian clock.
@Gray Au You can still buy those retro vintage Edison LED incandescent bulbs. They are literally indistinguishable from the old tech, except wasting way less energy. They literally produce the same light.
And I loved the project will surely give it a try
Wow!!
I would love to know how to make a more permanent DIY bulb, I am concerned with the amount of time it can stay on. Is anyone able to point me to additional info? This was great as a first pass to identify the basics, but it's not a long term particle solution, however I could imagine a couple of simple modifications that might get it there... I guess I will be clicking around until I find something of critical importance to further my knowledge. Thanks so much for making this.
i bet after 9 months you have already found it, but it needs a vacuum or some kind of gas to prevent it from turning off
@@md-nv4rg I wonder if you replaced the gas inside with helium or something similar, would it displace the air and prevent it from burning out?
@@Saroyus Yes, that's how incandescent lightbulbs are made. Any inert gas will do the job.
I saw a video where a guy used a little bit of propane inside his bulb to react with the oxygen before it could react with the filament, sounds sketchy but it worked🤷🏼♂️
Ah. Sweet. Just the knowledge I needed to manufacture my own lightbulbs... And a sprengel mercury vacuum pump... For the vacuum. And tungsten wire for the fillament. Remember, things don't burn well in an environment that lacks oxygen to react with. They can still glow bright though.
wish you would've shown how long the bulb will last.
I wonder, if you could make this last longer with household materials by using the following methods:
> Use a candle in the jar, to consume the oxygen prior to switching on the carbon rod filament
> Use some drying agent ( salt, drain cleaner, anything hygroscopic )
> Use something as a seal / putty that does not contain water moisture
> Maybe even purging the jar with CO2 from a soda stream or helium from balloon gas or argon from a TIG welder
> use some tinfoil on the clamp-to-carbon rod contacts to reduce mechanical stress on the carbon rod
You could also use a different filament that doesn't burn/oxidize. You could probably use Kanthal and tune the length/resistance so it doesn't get over 1,500°c. It'd be a dull warm light (1,600-1,700k) but it would work in atmospheric air.
@@micheals1992 something that can not oxidize... Like an oxide. And that is actually a working solution... In a Nernst lamp ;-)
Thank you for your video 🌟 ... Is there any realistic way to make an easy homemade bulb that is more like an LED - safer/less heat and very low voltage, that lasts? ... If not technically an LED, something that has similar properties to an LED:
1) extremely low voltage
2) good brightness relative to tiny size
3) safety (no/very low heat).
It only needs to emit a very small amount of light.
* This is for a non-profit creative project. The project imagines the possibility of basic electricity being used in an alternate world where the technology is lower than ours.
**I imagine a rudimentary battery (like the Bagdad Battery) would power the tint bulb.
Thank you in advance if you (or anyone else) can help. xx 😘💐
The swirly one is not incantdecent its a CFL.
Your bulb lasted 14 seconds. Ya big deal.
When one of Edison's early light bulbs burned out in 40 hours he considered that to be a flop.
Actually many of his first experimental lamps only lasted seconds as he tried to make this work in open air. He was a very good experimenter, but in some cases it seems to me not a very good thinker. It took quite some time to get to the point where he would use a vacuum, partially to the means of creating a good enough vacuum becoming more available at that time that finally led to success in combination with the design and manufacture of the early carbon filaments.
What’s the voltage of the battery?
If you use nitrogen instead of air it will be better for the light bulb ..
If you had any idea what you were talking about you would say argon. This is a kid's project, you don't need to flaunt your "intelligence"
If you had any idea what you were taking about you would say a mixture of nitrogen and argon to prevent arcing. Or better yet, xenon. But of course any inert gas is way better than regular air.
@@martinsmith3847 If y'all actually had any idea what you were talking about you would say a vacuum is the best filling to prevent heat losses through convection in an uncoiled filament, specially if made out of carbon instead of tungsten...
@@johnkollon3754 vacuum is not as easy as you think ... of course vacuum is excellent but its much more easier to find argon or nitrogen than to use a vacuum pump if want to do it yourself ...
@@TheCerberusInferno Indeed, the easiest way would be to fill it with butane which is very easy to find and handle and also will react first with any oxigen left.
Why not just use magnets to produce energy?
Electromagnetic power conversion goes hard when you load it example when you connect a motor to a led the turn it it will turn harder than empty because there is a current load. In this case incandesent bulbs draws tons of current and that caused to them get banned from european union.
Will 0.7mm graphite work?
Of course!☺️
dosent work. Just smoke thats all
+gameboy666666 Hello! Sorry to hear that. Try again and let us know if it still doesn't work for you. Make sure that your seal is airtight and that you have the battery hooked up properly.
its ok now. Had a crapy cheap bateries
You are pretty
3ah, for anyone wondering
An amazing experiment, thank you. However, i would advise to stay out of politics.
both talented and cute
