Ciao sono Roberto purtroppo non conosco l'inglese puoi gentilmente scrivermi gli ingredienti così posso fare la traduzione in italiano Grazie

Why not just add the Na₂SO₄ at the same time into the carbon mixture

I saw this film from 1959 where someone made a very crude lead acid battery by just putting 2 solid lead plates in an acid solution and charged it for like a minute, it was able to power a pretty powerful light for like 10 seconds. I'm probably gonna make one like that someday cause it's more like how the original one from the 1850s worked.

Please sell the mag paste material, I need this to power a small silicon inverter, with a transformer to power a motor, when you jave a little power you can make more, no moving parts! Just thee motor, this powers a gererator to make more power and is the root of my whole home power so you see why I Nedd this. Thankyou so very much!

You can use Tamarind water to clean this copper foil ! and Much Safer.

What is black solution?

Hello. Is ionized water the same as distilled water? if not, can you use distilled water? Doesn't the glue weaken the conductivity? what glue is this? what type? it reminds me of wood glue. Regards.

I’ve been trying to look for a powder that makes non-drying gel from water to mix with sand for a science experiment for kids. Thankfully PVA has proven itself a good candidate. This video helped a load, thank you.

Please let me know..how to make sure polarity + / -?

Hello, don't you use a separator ? it seems to be important

2.7v pra essa destruição aí. No mínimo 100v pra isso, sem contar que eles descarregam na hora se fechar curto sircuito

Could u "refuel" the magnet? I think that magnet will weaker

👍👍👏✅🤗🤩🔋

This is not advanced, 2 volts is normal, and you didn’t get 1amp, you got 0.1 amp there.

This is a capacitor, not a battery. A battery uses a chemical reaction between the electrolyte, anode, and cathode. Although similar, this is a capacitor with just some salt water.

What is the binder?

What is price of supercapacitor..? Can I charge it with AC current..?

Brokie just buy a new soldering station

Rubbish

Roll one the size of a grain bin and charge with solar.

It works same the Alumium you maked right?

Could graphite paint be used?

Hello sir, I am doing research on different methods of producing graphene, do you think it would be acceptable to vaccum filter out the graphene after it has been sonicated, or is it better to let dry?

Bro how to connect you made speaker to phone tell or appload vedio

In this SCAM. there is most probably a lithium battery inside the plastic tube, SCAM, SCAM, SCAM.

hi can you tell what is charge discharge life expactancy

i don't remember becoming friends. pro-tip this creepy to call people your friend 1000 times in a video

Yorumları tek tek okudum yorumların yarısında iletken olan demir oksit için fe203 demişsiniz bir çoğunda fe304 demişsiniz sürekli aynı soru sorulmuş her defasında kafanız karışmış.Doğrusunu yazalım insanlar uğraşmasın fe304 iletkenlik özelliği olandır.İçerisine koyduğunuz yalıtım boyasını (plastikleştiriciyi)çok kullanırsanız iletkenliğiniz o kadar azalır..

VERY good project! Thanks!

rulo yapmak yerine karbonu daha katı katman yaparak kare şeklide kullanmak kapasitede düşüm yaşatır mı ? rulo halinde yapmanın spasifik bir sebebi var mıdır?

no free energy exist

V bad audio quality also video editing .... U can.t see his whole head in video

This is not 100 farad

Two things: - the CD case cover you are using to paint over is a different one than the other one where you are measuring the resistance. Why ? - when someone asks you why their Fe2O3 powder is not conductive you say that the good one is Fe3O4, but when someone asks you why their Fe3O4 isn't working you say that the correct powder would be Fe2O3 ... So which one ?

How? What is the wiring path?

Por favor legenda

2.7v 500F 😮

you basically made a battery

It’s just a ferrofluid. Nothing special Shake the bottle then then the ferrofluid transfers magnetic force from the small magnets to the coil which then stores it as an inductor. This is called a faraday generator and is over 200 years old

I'm gonna make a billion dollars with this design and not even give you any chicken or melon.

tnx 4 sharing knowledge , how 2 make 12v from it?is it rechargeable?

Fake, how TF those particles gonna vibrate? Is that a joke?

0:37 ¿What is the name of this liquid that I need to make my dust cap for my speaker? Please

thanks❤why dont make a cap with high voltage?😢

Have you tried mixing oxides with PVA glue?

2 omz is higher :D .. SBR helps you get below 1 Ohmz with graphite and carbon black..

instead of using plastisizer , You could use SBR..Its cheaply available.. Added to cement for hardness and anti crack :D .. water proofing..

I have easily received a joule thief from the converter from a 160v 1.2v battery

What's the black stuff po?

That's just 10uF.. It'd only start to catch my attention when I see above 1k Farad.. otherwise it's boring
