Invention from used 1.5V batterie that you shouldn't throw away 

Please subscribe to my channel thank you 😊

The way you use tools I am surprised you have all your fingers

Thats 8 minutes of my life I'll never never see again.

My good man, I would like to take a moment to reflect on your total disregard for your own safety whilst using handheld tools, firstly never hold an item that you are about to drill in your hand. secondly use the correct size drill so that you do not have to ream the hole for your next piece in the project to fit, thirdly, ensure that your drill bit is sharp and does the job with ease, fourthly never use a hacksaw blade held in your hand, it actually has a frame to secure it in, fifthly never pull a hobby knife toward yourself when cutting objects you are holding in your other hand, it is a sure way to cut right into your tendons rendering your use of those appenditures useless.

Yes, holding a piece of wood in your hand as you are drilling it, is a million dollar idea for the medical industry. The battery in the drill and cutting the top of the battery off with a hacksaw blade, held in your hand is brilliant.

It would be nice to explain your actions. Especially at the very start of the video. The goal, the task origination, plan of the work. What are you doing and why.

I watched the first 5 seconds of the video and went straight to the comments and you lot didn't disappoint at all.

Just what I've always wanted to do, weld 2 razor blades together, forget it

So, guys, don't throw away your old razor blades because you can always weld them together and then you can, err...

"This video serves as a reminder that innovation knows no bounds. By repurposing used batteries, the inventor demonstrates that with creativity and determination, we can solve everyday problems and make a positive impact. It's a testament to the endless possibilities of human ingenuity. Let's strive to find inventive solutions to challenges big and small. Thank you for sharing this inspiring message!"

I followed this video to the letter, and I'm mighty glad I did. My morning shave is done in half the usual time, which means I can now watch even more of these videos. Thank you!

Вижу практическое применение такого "сварочника" в замене элементов в аккумуляторах шуруповёртов всяческих...там несколько аккумов между собой последовательно соединяются стальной лентой, которая чуть толще лезвия бритвы - как раз подойдёт

Have not seen one of these that are worth the time! I just like to read the funny comments.

I just made a giant razor blade now all I need is a giant razor blade holder and a giant box of plasters.

That was a lot of trouble to go through, when you could have just superglued the razor blades together! 🤔

Dude,you need some decent tools to work with before you hurt yourself.

Если вставить это ваше изобретение на в антеное гнездо телевизора, а в розетку электрическую на вашей стене, то эффект тоже будет потрясающий, ГАРАНТИРУЮ!!! 😁

Ah so that’s how you do it! Always wanted to weld razor blades together ( don’t really know why).

When you absolutely must weld two razor blades together.

Dullest drill bits I've ever seen, and the luckiest fingers. But thank god I now know how to weld my used razor blades.

Actually, folks this is an excellent general use spot welder. Very useful for rebuilding rechargeable battery packs for power tools and such. Individual tabbed cells available online, but need to be welded in a way that doesn't damage them.

????!!!! Thats 8 minutes of my life I'll never never see again.

Praise Comment: "This is truly innovative! Turning used batteries into something useful is both eco-friendly and resourceful. Great job!"

After watching this video, I am really surprised he doesn't have cuts and gouges in his hands and fingers!

Now you've made one of those mini spot welders you'll be well equipped to securely attach wires to bits of metal to your heart's content. 👍

Great ingenuity....but now that you built a long razor...what do you use it for?

maybe save $5 - $10 for a Soder tool but the comment entertainment is priceless

As an amateur radio operator who makes radio kits this is going to me huge for me. Thanks for not only saving me a LOT of money (spot welders are usually over $100 USD but giving me another fun project to make.

That’s 8 minutes of my life I’ve just wasted…

I'm heading straight to the store to buy two razor blades...

It's an imaginative assemblage of various implements to get to a definite result, it;s an interesting proof of a concept, but what was the power source you held up there for a few seconds? it's obviously got a little bit of power behind it, but is that power unit some discarded unit you are making use of for this Mini-mini-welder? The photography was fine, but the presentation definitely needed some more instructions and descriptions of things. It could be followed well, but some captions would have been a help.

Wow you just reinvented the wheel

I was quite surprised to find that at the end of this video, you appear to still have ten fingers. I always said, if you're not living on the edge, you're just not living. By the way, how many eyes do you have right now? Just curious.

I'm not sure, but I think that just might void the manufacturers warranty on everything seen in this video.

For me it was helpful. I’ll definitely will try to make it. Thank you for sharing with patience. Regards from Japan

Да Класс! Этого я не знал. Спасибо за. науку. Браво!❤❤❤❤❤❤❤❤❤❤❤❤❤❤🎉

Greetings from Australia -- a little spot welder - you beauty. Suitabl to weld lug battery cells??? Thank you

Удобно делать большую батарею из нескольких батареек, используя это для приварки жестяных шлейфов на полюса батареек.

It's pretty obvious he just made a spot welder out of a battery, copper tube, some wire, a screw and some wood. Almost forgot the electrical tape.

Can you post a picture of your face after using your spot-welded double razor blades to shave with.. 😂

1) Tell them what they are going to see -- how to make a spot welder 2) Show them -- make the thing 3) Tell them what they saw -- metal spot welded together with the device that was made

Back in the 60s I used to use D cell rods upped the voltage and made carbon arc welders that packed a ton of heat/light. It can be used to weld but don't try it, one mistake could be your last. But many welders can bite you if you're not sure about what you're doing. It was the same principle as BLG has shown you here.

I'm usually pretty harsh on what many consider worthless videos. This is not one of them. By spending the time to complete these small projects, you learn the very means by which such equipment works. I spend an inordinate amount of time dismantling used equipment to gain a better understanding of how they are constructed. It's helped me my entire life. Keep sharing. Never mind the negative comments by "armchair quarterbacks" who probably spend more time playing computer games and surfing porn. Thank you.

A spot welder. When I was a kid I made a soldering pencil that was powered by a 12V car battery by filling a metal bullet shaped pen cap with carbon granules.

I think it's the Chinese way of hacking into your computer while you are distracted by the insanity!

Some of the comments here make me really wonder. Do people really think this - mini welder - is made for welding razorblades and the likes together? If one is a homeworker and needs a lot of very small and little welding. It is a good idea to have such thing. Sure it will take time to make one. But isn't it also the fun - I can do it myself instead of buying everything -?

فكرة رائعه .. لا تكل ولا تمل .. وسر على بركة الله وحاول فقط كتابة الترجمه العربية لما تشير إليه مكتوبا على الإجهزة التي تستعملها.

This reminds me of something MacGyver would concoct on the spur of the moment.

Ingenious use of easily found materials to create a pretty sophisticated tool. I've just acquired a MIG welding outfit for larger stuff but was wondering if I could spot weld small stuff and indeed this is a nice compliment to my arsenal. Cheers.

Well, that was eight minutes I'll never get back.

Ok here's some positive feedback that will be worth taking on board We have been using the very same principle to rebuild damaged car/truck battery poles for years / an old French mechanic showed me . Clamp a piece of flat steel in the gap of a spare terminal / +ve or -ve whichever is required , hook a jumper lead to the battery's other terminal / do not do this with a hot battery , cover it with a wet rag , never had one explode in 40 years . I actually use an arc air gouging carbon now , however a Big Jim torch 6 v battery has 4 good sized carbon rods inside . Okay . wire brush what is left of the terminal , make sure you have a stick of 50/50 plumbers' solder on hand .Touch the carbon rod onto the damaged terminal and carefully melt the lead down to meet the mold - too hot and it will all run out under the mold , (yes I did that the first time) the carbon will heat very quickly so gently as you go, now use the red hot carbon rod to add the solder into the lead surface puddle and build to original height , let it cool and you're back in action . Wear safety glasses!! Cheers NC

Inventive Electrical!!! thank you! welding in any form is interesting. Detailed vid!

TWOT ...... Total Waste Of Time

Excelente esa soldadura por puntos!!

That was a great and inventive way to build a spot welder. Thank you!

SERIOUS QUESTION: Is there no danger of battery acid? Thank you.

I like it. This is absurdism at the level of Monty Python. This is high level humor folks. Try to understand that!

Классная идея для пайки проводов к батарейкам, акуммуляторам 18650 и им подобных. 💪🔥😎

Do they still have carbon rods in cheapies? Good for fixing squealing disk brakes.

La aplicación del ‘carboncillo’ de las pilas me parece estupendo. El hacer soldadura por puntos así, estupendo. Lo que yo haría diferente sería hacer el taladro del tubo de cobre antes de fijar el otro extremo, pegado con loctitte. Si lo haces después y encima lo lijas, se puede soltar de la parte de la madera. No les hagas mucho caso a llos haters sobre el como usar las herramientas, se les ve que no tienen ni put...idea de cómo se usan los útiles en la realidad 😉 Saludos.

Was it an masonary bit you were using to drill the bit of wood, and could you put it into fast forward as i have never been so bored looking at a bit of insulating tape going for a run around the same bit of wood

What a brilliant way to repurpose used batteries and contribute to a greener future! This video not only showcases a creative DIY project but also instills a valuable lesson in environmental stewardship. By turning waste into something useful, we can all play a part in conserving resources and minimizing our environmental impact. Thank you, Inventor BLG, for sharing this insightful and inspiring content. Let's all strive to adopt a mindset of innovation and sustainability.

Как всегда, они додумались через сто лет Изобретение с очень длинной бородой😂

He reminds me a lot of myself. I give ZERO hoots about my safety.

good to keep in mind if you need small graphite rods

Интересная идея и главное из подручных материалов, правда я не знаю кому это может пригодиться, но знаю много людей которые любят такие штучки. Может эту идею удастся кому-то приспособить ещё для чего нибудь. Удачи!

Your drill bits are really dull.

I can’t wait for the sequel where our hero welds 2 cats’ tails together

Brillant solution for solding razor blade but also assemble battery pack. Did you consider the battery assembly element ?

Слишком быстро всё показано. Надо крутить на уменьшенной скорости. Как прикрутить провод к угольному электроду показывали всего 8 минут. Браво!

For your next project - I suggest you "spit" in the air - and investigate how the law of gravity affects the way your spit moves. It would be way more entertaining and a contribution to how to turn nothing into an event.

КЛАСС ! Все пишут про технику безопасности . КИНО . ТОГДА и хлеб не режьте ножом ломайте , а то порежетесь и так далее

I made one of these when I was in grade school for a shop class project. Since our power supply was just some D cell batteries, all it would do is engrave into light steel. It would etch your name or whatever. I also pulled the carbon rod out of some AA batteries for the tip. That was like in 1966.

Ya te comente mui ingenioso tu teabajo.en cuba trabajé de tornero muchos años.y me gusta los inventos.lo q me llamo la atencion fue que con pocas herramientas mira lo q logras.felicidades .

Более умной идеи я не видел. Молодец! Гениально!

Super 'iridium' razor blades are apparently stainless steel coated in platinum!

직류용접기ㅎㅎ.. 좋아요~~

Ik begrijp enkel nog steeds niet in welke context je dit kan aanwenden/gebruiken maar ben wel onder de indruk van jouw kennis

Видимо запасные руки есть..., при отсутствии мозгов. Берегите себя ! Наглядный пример как нельзя пользоваться инструментом.

Чё правда чтоли? Это все? Медная трубка взята для большего времени видео? Ушел паять бритвенные лезвия вместе))

Единственный вывод - надо скинуться всем сайтом и купить ножовку к имеющемуся полотну

Quite brilliant but no idea why. Could I use to spot weld a steel pot handle fitting back on the steel pan?

I Made One Of These And Started My Own Welding Business!!!

Супер сварка, всю жизнь мечтал, такое сотворить.

Этот ужастик надо было в замедленном воспроизводить! 😊

You really need a drill press and a drill press vise.

Great! I've always wanted to weld my razor blades together!

Так то идея сия еще в Юном Технике публиковалась. Применение тогда было для пайки медью

Interesting - But I doubt I will ever have the need to weld two razor blades together for any reason.

purple wire is the ground or negative probe. Braizing hard metal is impossible with a soldering iron. Great project

Работал на стройке в молодости. Монтаж антенн ТВ. И приходилось распаивать соединени. Просто брал трансформатор на выходе 12 вольт и угольный стержень от батарейки. И ни каких заморочек обваривал пртвода соединений.

I'm surprised you could afford super glue and electrical tape!😮

Interesting. Similar principal to the way fires are lit it prison to smoke and brew hooch.

Edison and Tesla would have loved you!

Muy buena idea, pero mas lenta que el caballo del malo. Un poco mas rapida seria Genial. Un saludo.

Good way to meltdown your mains adapter?

Joke. The beginning of the century, the teacher explains at length and in detail the structure of a steam locomotive and, pleased with himself, asks: - Who has any questions? One student rises: “I understood everything, Mr. Teacher. I just didn’t understand where the horse was harnessed.” So here too - everything is clear, except why such a low-power power supply.

In the first minute of the recorded video, We see you holding that narrow piece of wood during drilling. Do you realize if the bit finds sufficient resistance (binds) while turning into the wood piece, the you could loose your grip on it wood piece and drill bit starts drilling into your hand?

Хороший удлинитель лезвий для бритья!!! 😜

I think it's better if you buy one and forget all that work
