Be very careful about using Better Help. They've already been fined by the FTC for selling personal client data to third parties. That is NOT something your therapist should do

Love that the experiment demonstrates the formula for water by giving you 2x as much hydrogen

This just goes to show how difficult it actually is to make many common things we can get today.

Great video! I think the issues you were having with the final battery when charging the phone was that your copper layers were touching and shorting out. If you put larger diameter pieces of soaked paper (instead of more pieces) between the layers it should keep the individual layers from touching and give you a more consistent output. Great job as always!

"Partial success" is the motto of this channel.

Man I love this series, it's everything I loved back in the day about TKOR and Cody's lab. This also got me into Dr stone. Keep up the good work I can't wait to see what you have planned next

That stack of metal and fiber, doused in salt water lighting up that LED light was a really cool visual of the basic principles of a battery. Mind-blowing!

My mans the irl doctor stone

Somehow, even though when I think Zinc, I think electrochemistry, since I relate it more to sacrificial anodes I totally missed how Zinc is perfect for batteries, even after you created capacitors! You slipped right into early electricity without me even realizing!

I love this show. Today I felt that the concept wasn't explained as thoroughly as other times and now that you're reaching more complex topics, maybe it's worth to explain them more thoroughly

The battery pack controller you used in the end might have just realized it's not a lithium cell. The voltage range lithium cells run at is very small. So when yours dropped below it, the controller shut itself off to protect the cells. Aka your battery isn't dead. Just power than lithium. And also: open circuit voltage is bit representative of the load capacity.

In 1801, the First Consul of France no other than Napoleon Bonaparte himself, invited Alessandro Volta the father of the battery to come and present his battery in Paris. On November 7, 1801, Volta began a speech on the theory of galvanism before the National Institute of Sciences and Arts. The presentation lasts three days. Volta demonstrates the efficiency of its electric battery. Bonaparte was impressed by the scientist to whom he gives the gold medal while making him count. Napoleon also established a competition to reward the best research on electricity making the breaking point in electricity research and understanding. He understood it was one of the energy of the future and like in most matter was right.

It's funny how early electro-chemistry seems to be overlooked when people talk about the industrial age. It's all steam, oil and steel production that get all the hype, but electricity really played a great role in separating the elements. Even the discovered elements came about right after the battery was invented. This is my favorite part about chemistry - at least the history of chemistry. I've been really enjoying this series and I love how crude the "first drafts" of each recreation is - really gives insight into how things progress through trial and error, like with the saw frame a few episodes ago. A "perfect" saw blade would probably have reinforcement and connected to a watermill, but before you can make that, you "need the tool to make the tool" (the whole premise of this series!), and that's the early prototype that gets all bent and contorted with the first tree knot it encounters. Then there's all the other tools that need to support the new tool you're trying to make. Also, I've always wondered (after reading a thread some 15 years ago - It's become one of those things I like to think about when I'm bored - on an AlternateHistory forum with a hypothetical question of "If you dropped a group of people off on several large islands..."), just how quickly could someone recreate, let's say, cell phones and PCs starting from scratch, assuming they knew what they were doing (a speed-run if you will). Would there be a bottleneck for 1 person? a few hundred? Few thousand? How many (at a minimum) are needed for an industrial society? A modern society? Sure, you can make a simple battery, but you need the miners, the glass blowers, builders to construct factories and warehouse, housing for the workers, farmers and ranchers for food, and so on. This series goes a long way in answering these things.

Great job. I rebuild batteries for home. NiCd batteries are a bit dirty when they have been used for quite some time. I clean the plates and container. When I am done with the cleaning, I check the battery cell for shorts, then I fill the cell with a new electrolyte. The following is very important to do. I run charge and discharge cycles. All batteries must do this. It helps stabilize the charge and how much current can be used over time. I first discharge then slow charge full. Then I discharge to 40% for NiCds. I finally run this cycle for about 3-4 times. I have batteries that are in over 30 years of service.

Been following your channel for years and was scrolling through your old videos. It is absolutely incredible how far you've taken this all! Despite all the challenges, you keep pushing forward and it's super inspiring! Keep up the great work! ❤❤❤

Next time you cast metal with the lost wax method, build in gas vents from the discs back up to the surface. Or at least a good way from the cavities. That will allow the metal to not have to try and compress the gasses inside the mold. Or you could attach the mold to a string and swing it around employing centripetal forces to push the metal into the cavities. Both are tried and true methods of improving casting results. Also try having a larger funnel shaped hole at the top to allow for more metal in your pour. The increased weight will help push the metal into the cavities, plus the excess metal reservoir will help when the metal starts to shrink when it cools.

can't wait to see how the lead acid variant holds up!

Great work, Ive been watching since the start of the the series and your skills have greatly improved, I love the content you create

Best episode in awhile Brother! Really love how you got your hands back on the project and really hit your roots of doing everything yourself! Respect ✊

Curious why you chose to cast the discs instead of working the metal thin and cutting them.

Damn, that beat @ 5:00 got enlightened, the soundtrack HTME uses is one of many reasons I love this channel.

I love the use of the hand tools ! 🔥

Loved the episode and the history as always, another great video HTME team! For casting, maybe it would make sense to put tiny holes in the mold to let air escape as it fills?

With a USB supply/discharge controller more suited to the chemistry (that one was intended to cut out anytime it got outside the very narrow safety range of lithium cells) you could probably get a lot more power out of that homemade pile.

I always loved the classic TKOR video on penny batteries.

Haha as teens used to use a car battery to split water and we collected the 02 and hydrogen in milk jugs that we'd throw in the fire

Loooved the museum bit

have you reinvented the shovel yet, i heard it was ground breaking!

In one of those molds, you had spattering from the liquid metal due to what BigStack D refers to as a steam explosion. The molds had moisture in them when you poured in the metal, and the suddenly heat made the moisture rapidly turn into steam. Thankfully, the reaction was small, but you need to preheat future molds beforehand to prevent that from happening.

I love that I know that the video was film recently (at least the outside shots), because the weather lines up with the crap we're still dealing with outside. Love from the Twin Cities!

May I make a suggestion? Use plate separators that are at least a 1/4 over each edge of the electrodes. So for 4" sq. plate electrode use 4 1/2" separator. I believe you were shorting around the edges, and even at low voltage there could be added self-current drain with exposed plates. It also leaves you with more electrolyte per sq. inch giving more ion exchange.

You make everything thats awesome you got yourself a new sub 😊

@How To Make Everything. There is a Sodium something Pile battery in a Museum somewhere, that has been ringing a bell for god knows how long, but no one has tried to re make this battery.

I love this stuff! Please more batteries!

Human creativity and ingenuity is mind blowing. Just wow

So did you examine the inside of the blowpipe afterwards? It occured to me that some zinc might've deposited on the inner surface of the pipe.

My all time favourite MHA bit has to be the epic battle on the island when decku gives one for all to the kid who's been bullying him his whole life to save the kids and islanders the animation is next level i had to take extra meds after watching it because it triggered my epilepsy was totally worth it .

absolutely awesome work here

Miniminiuteman has a fantastic video with a lead reasearcher that gives the best modern interpretation of the "bagdad battery"

a mud coating over all the container was used to keep the gas from escaping including any steam and that would push all the gases into the water. the entire mud encased was heated, cooking the mud and melting the metal inside. temperature was maintained very high with bellows.

4:36: when she said "BOOP" I enjoyed it!

always wanted to see one of those in action !

I remember years ago when I started watching his channel and wondering why he didn't have many subscribers. Look at him go 👏🏼 I knew this channel deserved and still deserves much more subscribers 🎉

What a shocking video! I'll resist making more puns.

LM7805? Was cool to see you crack the batterybank open to smooth the voltages. I'm curious how much longer it would've charged if the copper&zinc sheets were put in a Rubbermaid basin,for example, so they're constantly submerged in the electrolyte. Cool video.

I like your window shade in the background.

FINALLY electricity

I was wondering if it would perform better if you combined the voltaic pile with a leyden jar capacitor , and maybe some old style diode like a pencil and razer diode.

I was just gonna comment at 10:00 that's not how to build a battery, you need different metals to be touching at every 2nd gap, but he found out shortly after. Please do a Lead Acid battery, but be careful with the dangerous substances involved.

These last two videos felt quite significant. With electric power, the modern age is beginning for HTME. I would like to see hydro power generating current some day. Take your time, the journey is the goal.

Another amazing experiment!

What's I find most fascinating and the whole thing is that a metal can travel distances as a gas.. wild. Also, if you preheat your overfill molds a bit with a torch before you pour, it won't pop and splatter like that

Thorough and amazing!

Brother you have running like clockwork and so BLING BLING 💪👀🤙

When it comes to knowledge about electricity, I like to stay current.

Thanks for sharing

3:39 "Today we do electrolysis...". So, once you have your first battery, you can get the zinc for the next ones quicker :)

I feel like you might be able to get a bit more charge time out of it if you remove air from the equation. Put the whole stack in an air tight tube or some such, fill it with brine, let it soak for a bit, drain excess brine, seal the whole thing, and _then_ see how long it charges.

I'll have to remember this when I go back in time, so I can charge my phone. Thanks!

The first historic battery mentioned was the Leyden jar which isn't a battery, it's a capacitor, no chemical reactions occur during charging and discharging.

Well done!

Amazing thank you for this video

At the 9:58 you can see that you are putting it together right. The copper and zinc take a felt separator but the zinc and copper must make contact. copper + felt + zince + copper + felt + zinc etc.

this is an important lesson for all those time travelers ;) - try using a 'magical' knowledge device with older technique, I guess devices with PD won't be so 'easily' recharged

One of the best UKpostsr right now

What makes the plates "spent"? Are you able to renew them to be used again?

It's not that the battery is discharging quickly. It's that it's internal resistance is high. When you measure without load vs with load you can calculate the internal resistance. Bottom line you need way more surface area to keep the load down on each cell.

Not related to this video, but you really should do a video where you make a surface plate and accessories. The surface plate is the single most important tool used in machining and measurement, but is so simple that one can be manufactured from just rocks (though metal or glass might be preferable). You don't really need any other tools to make one, either, just an understanding of some clever geometry.

Can’t wait tell he makes it to the first car he’s slowly getting closer

A mini one made from pennies could work in theory. Using all copper and stripped zinc ones.

Great video!

Love how real these episodes are. Instead of 'we asked nasa to laser cut zinc and copper plates for us to be precise'

i found it so cool with the hydrogen and oxygen electrolysis experiment, you can see how there is twice the level of hydrogen, since there are 2 hydrogen atoms to each oxygen in a water molecule

You need to make the same, only on dynamic flutes, revive it active.

you're a brave man to just plug your phone straight into that

Hey, I know you already have concrete and such but like... go check out Primitive Technology's iron bacteria concrete, I think that could also be an interesting material for potting with

insulating fabric layers need to be larger to insulate the metal plates better

I made zinc disks out of metal jar tops. Way quicker/efficient/ nice disk shape than lost wax.

Question, if you were incase it in a glass tube or in some thing with the salt water would the voltage stay the same longer

I member making one of these after seeing a king of random video about it like a decade ago

I think (don't quote me) that the piles function a bit better when submerged in the solution of either salt water or a weak acid like vinegar or lemon juice

can't wait for me to become dr stone learning absolutely everything

It’s a good idea to heat up your mold before pouring… so it doesn’t explode on you like it almost did…

Really make you appreciate the modern battery

Yes more dr. Stone stuff

"fairly tight seal" explodes because of the "Fairly Tight Seal"

How far back in tech time could you make a transistor?

I think the gas between the cells is blocking the battery and that's why they later used different arrangements. A simple solution would be for the voltage to be below the point where water is splitting. ... and then the electricity has to be transformed

"If you're lost in the woods you can make this quick and easy setup to charge your phone to make a call!"

I feel like I learned something, but I am not sure what it was. Great video, I am not too bright!

Awesome stuff

Wow. I had no idea a voltaic pile battery would go flat so fast. Somehow I always just thought they'd probably lasted for a few days.

The Camera work was great when u were at the museum

Take modern penny's and rub one side on the sidewalk till the copper plating is sanded off and the zink is exposed, stack them up with wet construction paper in between and you have a cell. U can then run more identical sized cells in parallel/series to achieve desired voltage and amperage. Just remember ohms law and you can power anything with enough penny's and urin/vinigar/saltwater.

Use the laminar flow nozzle. Called a SEN use a big block of metal as a mold will probably have to rig it to be cooled lots of flux like borax . The cooling rate it the hard part. X steel mill worker BTW

Couldn't you drill holes in the battery plates to increase their area in contact with the electrolyte? Modern ICE auto starter lead acid batteries have grid plates to increase surface area and thus amperage.

That looks like a fun museum to visit.

Why choose lost wax casting rather than pouring into pits in the clay like you did with the graphite molds?

The thumbnail looks like an ancient Egyptian Djed pillar.

Good Stuff.
