i dont think anyone outside the electronic and RC hobby truly knows how much percision work this takes, the soldering in itsself is incredible considering he isnt using flux but the amount of percision work that must take is absolutely incredible! 10/10 work good job
That thing is actually pointless. Ever wonder why theres a off/on switch? Because if you not turn if off internal buck converter drain all the juice. So.. after he use his multimeter he has to open back cover and turn of his 9v battery.
I'm a maker but that got way too complicated for me. But you get 12 out of 10 for this video. Excellent and super engaging. You're a maniac. And I dig it.
Yes, he is a maniac. Because it is so out of economical sense of hat even Chinese do not do such stupid things. I use a multimeter with 9V battery often, once a day, and it last a year. That kind of battery is cheap, around 2 GBP. So max you can save using this device is around 1 GBP per year. Totally insane waste of time.
The coolest thing is you achieved 9v and all manufactures that sell rechargeable 9v Lithium batteries only really have 8.4V instead of real 9V. Also the stop motion was very cool, so much work!
Be careful about point-to-point soldering of the SMD parts, those things may easily get an internal crack after any shock in the assembled device, so better just order a PCB (this one is easy enough to just etch with a sharp knife btw).
@@risingmermo Like a couple of cents for a tiny piece of FR4 which for such a simple circuit you can etch yourself for free? And should we play some "big industry" here, the least expensive process is the one that takes the least manual operations, as it is both cheaper and less prone to human error, so fewer defective units per run.
Every one loves the stop motion. So did I. When you get to that part of the video it a little bit over my skill level. Probably could pull it off because this video is so good of quality but I don’t need a rechargeable 9 volt battery at this moment. Great video very well done
You can buy them, just google for it. I just found a set of two for 22,54 Euros, can't say anything about the quality. I guess the reason that they are not very common is that they are much more expensive than a "normal" 9 V rechargable battery, which has ab bit less capacity and needs a charger, but is still much cheaper.
Много ошибок: Ток заряда 1А, а нужно для этого аккумулятора всего 180-300 мА Нет охлаждения микросхемы при данном токе, выход из строя не избежен, если не сработает встроенная термо защита Повышающий модуль быстро съест аккумулятор(не будешь же каждый раз отрывать отсек, чтоб включить или отключить его) Нужно исправить: Заменить толковый резистор на tp4056 На повышающем модуле убрать подстроечный резистор, разорвать цепь активации микросхемы повышения напряжения, сделать датчик тока из диода 1n4007 и транзистора маломощного. Итого получается: в холостом режиме без потребителя будет напряжение равное напряжению аккумулятора, но при начале потребления в мили ампер 10 сразу включается микросхема и повышает напряжение до задоного, в режиме простоя модуль повышения потреблять будет не более 4-6 мили ампер
I just want to say how unnecessary the stop motion mini soldering was and the sheer that amount of detail went into creating just that short clip, it paid off… hats off to you sir you are incredible
Да на самом деле не особо сложно, куда только литий сегодня не пихают, больше не нужно особо. Вот села такая батарея в отсутствии зарядки или при отсутствии напряжения, надо значит запасную батарейку таскать, а при наличии запасной батареи не особо хочется заморачиваться таким ))), это где то добывать аккумуляторы, контроллер заряда, плату регулировки, и делать неразборную необслуживаемую литиевую батарею. Возможно проще купить никель металл гидридный аккумулятор. Два.
What a coincidence I just watched how you created rechargable 1.5V battery Your videos and procjets are amazing I love your cute animation how you move parts from pcb on charging port
Those DC booster circuits have quite high standby currents. It works but on devices with really low current draw the battery won't last that long because the booster circuits is active all the time. Tried to mod it on the resistors. Worked a little but still to high quiescent current. With firealarm devices you also have issues it won't give low battery warnings. It just dies immediately when the booster shuts off. But still nice try though. Easier to just buy one. More capacity and most likely better electronics.
With the things like smoke detectors, you're far better off just getting the intended "10 year lifespan" lithium batteries that use the same battery chemistry as lithium coin cells, with 3 stacked in series (edit: 3 lithium cells stacked in series inside the standard 9v battery form factor) to get the required voltage. They're individually expensive yes, at maybe $10 for each one, but given that they are intended to last 10 full years, they end up costing a lot less than alkaline 9v batteries do.
@@gt6hudson Agreed, but even those ones you can buy have the same problem. And they don't have the little slide switch in them so you can actually fully turn them off either. I guess if you want the switch, it would be a lot easier and probably cheaper to start with one of those and mod in a slide switch than to have to build the whole battery from scratch. Additionally there's another issue with the build in this video. Where does the charging circuit's IC get any heatsinking from? That's what that massive pad on the bottom of the IC is for. If it was me, I'd try to take that charging IC, bend the pins upward so I can "dead-bug style" re-make the charging circuit like was done in this video, but before I re-made the circuit I'd solder it to the inside of the (metal) case of the 9v. I'd also try to use a dab of solder to secure the micro-USB connector to the side of the case as well, unless that needs to be electrically isolated for some reason (but I doubt that). Shouldn't be too hard for either thing to be done, assuming you have the right tools and a sufficiently high wattage soldering iron. I mean the inside of the case looks to be bright shiny nickel plated, which means it SHOULD accept solder rather well, assuming there's no additional coatings or oils on it (so clean it first). Also, I tend to use lead based solder, but only because I still have a lot of it. When that runs out I'll switch over to the lead-free stuff, but that probably won't happen for a real long time, back when I was doing soldering more frequently 15 years ago I bought a half pound spool of 0.032" 63/37 Sn/Pb (eutetic as far as I know) solder from Radio Shack and I've kinda barely touched it, since most of what I was doing was picking components out of electronics that either became nonfunctional or were obsolete. Salvaged plenty of power transistors and good mylar capacitors from CRT TV's and monitors, and I was safe about it by waiting a week before opening it, and being careful around the tube. Never got shocked or broke the glass of a single CRT when disassembling them.
I did this and accidentally pierced the battery so instinctively I licked all the battery acid off my hands and now I’m in a hospital being told they have three days to live amazing DIY!
You are an inspiration as a kid I was always destroying /making stuff but you took it to the next level. PS I love the idea of you building the battery for your digital multimeter brilliant you gained my sub!
Забавная вещь, по сути могли бы сразу выпускать одну микросхему с выводами на подключение регулируемого резистора и вход и выход повышающего напряжения
Как один из вариантов, очень хорошо. Можно немного усовершенствовать, добавив ещё внешние контакты от переключателя, сделав их из жести.Это позволит подключать когда необходимо внешний переключатель, на тонких проводах с контактами из крохотных магнитиков.Тогда переключатель можно приклеить на лицевую панель в удобном месте.Желательно вынести так же микро светодиод, который будет показывать включен переключатель или выключен, для наглядности, чтобы минимизировать риск, когда забудешь включенным. Но тогда нужен дополнительный провод и дополнительный контакт на батарее. Может даже контакты из жести и магниты это через чур, можно микро разъём на три пина.
Чем такой город городить, лучше уж отказаться от преобразователя на MT3608, так-как холостой ход у нее может доходить от 5 до 15 мА. А все эти переключатели, не забыть выключить... Только если часто пользуешься. Но тогда лучше уж все в корпусе тестера реализовать, чем в крону пихать. В свое время, когда работал на предприятии, где изготавливались приборы измерения температуры, все тестеры переделали на литий. Наш инженер нашел какую-то микруху, у которой ток холостого хода был десятки мкА. На MT3608 заряд при небольших аккумах прямо на глазах таял, не успевали заряжать.
I think the only downside to this is that the lipo cells now parallel charge instead of balance. If one of the cell's internal resistance is even slightly different, you will eventually end up with one cell more charged than the other, and the charging circuit can't differentiate the two cells because there is only one charging channel. The other issue is that there is no overdraw protection. you could theoretically bring the voltage of the lipo cells low enough to be unsafe to recharge. otherwise, this is actually pretty cool
I think they would have to go in parallel because if you put it in series you would only get 3.7 volts well with the voltage thing you could overamp the battery but you'd still only get maybe 6 volts
Maybe in theory parallel seems bad, but in reality - parallel is actually good... as long as the cells are exactly the same type and age. It's really no different than a single physical cell but just bigger... think about it. It's also quite common in EV battery packs... Leaf battery modules are 2P2S, all Teslas have MANY small cells paralleled, then those groups in series.
Well, no. As both cells are tied in parallel they balance each other on their own. If one is charged higher than the other on the time of soldering it will charge the other to its potential and even them out. From then on they charge and discharge at the same rate.
You are incorrect about the cells being out of balance; they will actually be in near-perfect balance. You are also incorrect about the lack of over-discharge protection; it is build into the cell, which you can see clearly at 0:52
Super rad build! Most impressed I've been halfway through a video, as a guy who loves micro squashed bug circuits, and stop-motion. Could have almost fit another battery in there if you had micro'd the other board!
He didn't have the protection circuit, and his board was too big, i did the instructables on how to do a better version for cheaper : Convert a Power Bank Into a 9v Lithium Battery
I couldn't see any bms for battery, this boost module works until the input voltage decrease 1.5 volts so lithium ion battery probably will swell . bro you know low voltage of lithium ion is 3.0 volts😕. So ı wish you used tp4056 which have protection. Good job 👍.
I really like the look of 9 volt batteries so much that I collect them. There's something about the shape and proportion which is pleasing to me. I like to hold them in my hand and occasionally lick the terminals.
@@Carolina-mw4po switched power supplies make "noisy* power. it's fine for most things, but multimeters (at least the fancier ones) can be pretty sensitive to this. you can add a smoothing capacitor in there to help reduce the noise, not sure what size it'd be for a 9v, though.
@@DFX2KX i understand it as the conversion is done using a high frequency. I'm only saying I had no issues with my multimeter. May be it has a filter after the vcc, who knows. Even measuring frequency with it, the values are correct. I was lucky I guess.
@@manecior1 oh I got it. I also made my own 18650 charger with TP4056 chipset. I buy it with charge oc and discharge protection.only a little price higher.
Автор конечно постарался 👍 Особенно добавило изюминку, это видео в стиле мультфильма. Я как представлю сколько это нужно времени для монтирования видео, это взрыв мозга. Автор молоток ✊
TLDR, This project gives a "9V" with 25% of the capacity of a typical alkaline 9V. This is not useless but should be considered when deciding if it is worth attempting. This is much better than the AA project, more power in the package, easier to build, and using the switching regulator means you will get most of the power out of the LiPo. However, keep in mind, a typical Energizer 9V is about 5.5Wh (610 mAh x 9V). This LiPo is 3.7V x 450 mAh or 1.6 Wh assuming 100% which you won't get.
@@LFTRnow5.5 Wh in those non-rechargeables??? Those only have 600mAh @ 4.5Wh (real voltage is LOWER TO WAY LOWER than 9V for majority of discharge) Those are very bad at any significant current (0.3Ah and 2.14Wh at 0.1A)

That`s li-po with protect
Topssimo esse projeto. Muito bem elaborado...👍
Eu fiz um tutorial no instructables que ficou melhor que esse Convert a Power Bank Into a 9v Lithium Battery
how can u handle and work with such tiny objects so well ?
mad respect my friend
I did this at home once. Now I live in my car, but still enjoying TH-cam on the road!
I really like the look of 9 volt batteries so much that I collect them. There's something about the shape and proportion which is pleasing to me. I like to hold them in my hand and occasionally lick the terminals.
Cool idea and very nice video! 😉
Really nice! Although, I wouldn't recommend using a switched supply to power a multimeter.
I made it and my multimeter works just fine. Why you say so?
@@Carolina-mw4po switched power supplies make "noisy* power. it's fine for most things, but multimeters (at least the fancier ones) can be pretty sensitive to this. you can add a smoothing capacitor in there to help reduce the noise, not sure what size it'd be for a 9v, though.
@@DFX2KX i understand it as the conversion is done using a high frequency. I'm only saying I had no issues with my multimeter. May be it has a filter after the vcc, who knows. Even measuring frequency with it, the values are correct.
I was lucky I guess.
I am using that set up in my tester lcr-t4, and no problem at all.
This circut doesn't have dischatge protection. If you discharge batery to much you will have to replace it
looks like the batteries themselves have protection circuits on them
some battery cahrge board come with over discharge protection.
@@a892728 yes but this bartery charger doesn't have discharge protection
@@manecior1 oh I got it.
I also made my own 18650 charger with TP4056 chipset.
I buy it with charge oc and discharge protection.only a little price higher.
@@manecior1 no need for one if the battery has one
Most intresting part for me components moving part. It's Amazing 👏
Looks easy at all, like baking brezelz⬇️
Yea, but surface-mounted components are nearly impossible to remove.
*somehow removes*
just break it
Hint: hot air!
According to this video, you don't have to. They appear to move themselves. 😆
With the right method it is easy
Amazing 😍

Thank you for your kindness.
Автор конечно постарался 👍 Особенно добавило изюминку, это видео в стиле мультфильма. Я как представлю сколько это нужно времени для монтирования видео, это взрыв мозга. Автор молоток ✊
лишь показал что может, а так ее за копейки можно купить на алике
I am watching you from Turkey😊😊😊
Very cool. Looks challenging, especially the goblin-rigging of that charging module. Great work 👏
Wow amazing 😮 👏
TLDR, This project gives a "9V" with 25% of the capacity of a typical alkaline 9V. This is not useless but should be considered when deciding if it is worth attempting.
This is much better than the AA project, more power in the package, easier to build, and using the switching regulator means you will get most of the power out of the LiPo. However, keep in mind, a typical Energizer 9V is about 5.5Wh (610 mAh x 9V). This LiPo is 3.7V x 450 mAh or 1.6 Wh assuming 100% which you won't get.
((4.2V * 0.450A)*2b) - 20%Ef = 3Wh and you have the possibility to charge. i'm not pointing the nominal voltage.
@@Hudsonkem What is "2b" for that doubles the number?
@@LFTRnow battery :)
@@Hudsonkemnot that fast. 3.7V*.45Ah*2*0.8=2.7Wh.
@@LFTRnow5.5 Wh in those non-rechargeables???
Those only have 600mAh @ 4.5Wh (real voltage is LOWER TO WAY LOWER than 9V for majority of discharge)
Those are very bad at any significant current (0.3Ah and 2.14Wh at 0.1A)
With skills like these your a dangerous guy Penguin ✅😎 thank you for sharing I loved the finger Tp on the table when you were thinking
That was the best part to see what you’d do to make it work💯💎💎
You gotta be top 5 best in the world at this kind of stuff
Amazing
بنازم سلطان کارت درسته ❤️😂
is it durable
Olá amigo 👦. Ótimo vídeo e excelente explicação e apresentação. Nada é difícil e sim tudo é trabalhoso. Parabéns pelo trabalho
Sucesso sempre. Abraços a 👪 e amigos. Ok
Que trabalho maguinifico, show de bola... Parabéns 👏👏👏
Awesome! 👍 Good work!
Hay
Very Impressed, Penguin DIY!! You will rise fast! Don't change your style for now. Wait until you get into the 150K/200K. You are doing fine. Lights, motors, charging of Lithium Batteries. Establish your Base. This is good that you are integrating "enclosures". This one is exceptionally good. Professional level.
Love from Bangladesh 🥰🥰🥰
Wait 9V BATTERIES ARE JUST 3 AAA BATTERIES… MY LIFE IS A LIE
No, it's six of them and they are smaller than AAA cells.
বভ
6 x AAAA
Its only for duracell
Chill bro it's for Duracell only not for all 9volt batterys
Seems simpler to build a rocket and launch a tesla into space.
what if it explodes my house down
You should buy a better house.
Top notch.
Great use of stop motion photography.
Giỏi quá! Khâm phục sự tỉ mỉ và cách sắp xếp linh kiện của bạn ❤
Thanks for sharing, great idea
Subscribed cause you used stop motion which was just brilliant
The amount of work put to make this video !!! Cool one
Duacell must hire this guy. 😄
자기생각대로 이런걸 만들면 얼마나
성취감이 클까👏👏👏👍👍👍
Even though I can´t recommend you bulding a Li-Po charger in air, this thing is real. So I am happy, that you don´t film fake garbage, friend.
Fascinating nerdiness❗️ I love it‼️®™️ 👏👏
Can't help but think it's an accident waiting to happen. But the theory is fantastic. 👏
Highly talented 🤓
