Nice vintage well done.
You keep my mind at ease good sir, never stop!
Thank you!
Another great job ❤
Nice video continue 👏💯💯💯💯
Very nice G.S... Thx for taking us along...
New jump start as gift👍
Simple, easy and fun project. I enjoyed watching this one. Thanks!
Ok
you can direct power to 4.2volt, put all cells in parallel without stepdown
I think so.
Charging 6 cells in parallel will take ages because of the capacity :P
I think so to
@@micha3502 But if you have them in parallel, sure it will take longer to charge, but the flashlight will last longer on a single charge, so isn't that better?

Dear Sir
Its more than perfect restoration.
Top restoration 👏👏👏
Your videos are so inspiring. I hope to be able to do some of that work in my free time in the future.
We conduct
Good work! Thaks the video! Nice flashlight.
You.re best 👍👍👍👍👍
Thank you!
You restored a dirt cheap plastic flashlight 😐 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
I do like this project. I thought about transforming such type lights myself. Thanks for posting it and keep them coming. I was wondering about the power controller getting hot. You are controlling a lot of current. Heat sink(s) are important. Thumbs Up!
Good Restoration Flashlight made in Japan 👍
It would be more efficent to create a 1S 4P battery pack as this woud be colser to the required voltage.
this is better as the power wasted (causing your heating issue) by the buck converter (it would be a boost converter with my suggestion) is proportional to the size of the voltage change between its input and output.
I loved the video btw.
Yes, he did a 12v pack useless
That with losses being proportional to the voltage change only applies to linear regulators (which works basically like variable resistors). For a buck converter, the higher input voltage is used to store energy in an inductor, which is then released thru the freewheeling diode - which gives more current to the load than what's coming in on the input. It works pretty much like a transformer, but for DC.
Same but the opposit, applies for a boost converter - energy is stored in the inductor that is then used to boost the voltage. A boost converter will always have higher input current, as long as the output voltage is higher then the input voltage. Both buck or boost converters have 90% efficiency or more, if it's a good design. I think the main problem he had with the first buck converter was that it was simply too small, so it was overloaded (which increases the losses significantly).
No LEDs can be driven directly from the batteries anyway - they always need a drive circuit. It's not like a typical resistive load, such as the incandescent light bulb that was in the flashlight before. An LED can be barely lit at for example 3,8 V while it may blow up at 4,5. The voltage of the batteries usually varies way too much depending on their state of charge. The forward voltage is also temperature dependent, so they may run fine on a certain voltage when cool, then they become overloaded when they have been on for a while and get hot (a driver will usually compensates for that by lowering the output voltage slightly, to keep the current constant).
Charging will be a problem with 1s4p ( no any BMS & charging module to keep the unit safe ) . Using Buck Converter is a best solution.
Beautiful Work.
Excellent👍👍👍 . Thanks for sharing
Thank you very much, I have been waiting for you eagerly and have benefited from your work in remanufacturing a flashlight
Excellent project. I liked it ! My idol !

Лайк за отличную работу.
Obrigado pelo ótimo vídeo
Restoration and modernization 🔥🔥🔥
অনেক সুন্দর হয়েছে ধন্যবাদ
Thumsup for this video 👏 when I was 5yrs old my father brought a lantern rechargeable torch it had double pin charger pin torch with yellow flash I think it was geepas torch exactly like this light sweetable childhood memories 😊
Better than when it left the factory.👍👍
Advanced Congratulations for 500k 🥳
Love the channel keep doing your thing
Obsolutely the best informational video, cant wait for thr next video. Really good thing is ur old videos has same logic lots of information amd practical solutions 👍🏻👍🏻👍🏻
0:51 ha! Face reveal at this time stamp! Great job gearshow
😄 funny mistake!
Chinese face
Nice one mate
Thanks for the visit
Flawless!!! 👌👌👌
Good Job
Happy 500k in advance 🎉
Thank you in advance :)
Os melhores vídeos.
You deserve this gift
congratulations
Great video sir l love your all videos thankyou very much for this video 🙏🙏🙏🙏
Very nice 👍
Thank you 👍
I really enjoyed you video. I watch them all. In UK Li-Ion batteries are very expensive. I converted a similar torch to 2S x 18650 and 1W led. The led works fine with 4.2v and lasts for hours. No need for voltage convertor and much less cost of batteries.
I'm glad you like my videos. I build 12V battery pack for fast charging reason. Anyway thank you for sharing.
@@gear_show You might be interested in my new video. It is making a small gear puller for small electric motors.

The foam at the back of LED light might burn due to heat generated by the LED and back converter or DC/DC converter.
Bro your videos are very informative can you introduce your atelier +1
One of the coolest videos i ever seen honestly!! I really want to do this with old VHS video camera batteries from the 90s cause those cameras back then would drain the battery in like 2 hours.. lol
Yes, you should try it. I've been to apply this concept to my old tools.
@@gear_show sir please pawar bank Nime
Brother the led always wants excessive current that would produce more heat and there are more power losses i recommend you to use 2 lithium ion battery of 3.7 volt in parallel and remove the 12 volt lithium ion battery and also remove converter and use a 10 ohm 1 watt resistor in series to led and bateery that would runs longs
Amazing work
Thanks again!
Oh, I've seen same one at my home 25 years ago.
He really likes your work. You are creative👍🏻👍🏻✅
I want to know which country are you from?
Gear show de bola 👍
Perfect 👍
good job👍👍👍
Спасибо за видео!!!
Good job, I Always watch your new video, I am From Indonesia, sorry if my english so weak
Good work or aise video banaiye
It is easy to repair flashlight. Simple!
Yes, thank you!
i use this big buck converters to run my car’s headlights i also installed coolers for those converters i modded projectors with cree xhp 70.2 6v 4.8A
Good ideas and information 👍
LOLLLLL, he see less light, the finaly he changed all anything, that's amazing
Great job 👍
Очень даже неплохо 👌 лучше чем было однозначно
I like your all works. I see more your videos
Gampang banget.coba dari barang rosok pasti lebih joss.itu cuma sambung kabel dan bahan semua baru cuma casing lama aja.cuma ngerangkai doang
thank you teacher
I like your flash light nice you convert to LED and rechargable
Excellent emergency flashlight rechargeable and everything?
Nice Upcycling... Like
Good Job, verry nice.
i,d really like japanese flashlights!
Were are you from, Bro?
I am from Indonesia.
Good job. 👍
I'm from Cambodia, thank you!
I can see why you have so many subscribers. Excellent high quality videos. I have a lot of improvements to make.😂😂😂
Cheers Stuart 🇦🇺
Thank you so much :D

Jaaaaaaa...Muy Bien my Friend...Saludosss ji ji ji
Well done, the buck converter went hot coz you are reducing half of the battery power, it must reduce or increase small amount only, what about if you swap the plastic front clear glass with a real clear glass one?!!keep up the good work 👍🏻
Excellent job sir .Can you please provide for me the link where you buy this big reflector thank you.
It's a much better flashlight now.
Parabéns.
It so nice to see new life breathed into older power tools, I really enjoy the lithium ion conversions as well. Your channel inspired me to fix a broken sawzall that was about to see the trash. After watching your channel I’m determined to try and fix instead of replace
Omg! i have one of these they are like headlights of a car
VERY GOOD VIDEO!!!!!
Thank you very much!
Where did you get the new reflector and led module?
What emitter did you use? Should have used a warm emitter, around 2700K to keep the same color temperature as the stock light.
That's a handy gadget to have! What is the cost?
where can I buy a tool like the one you use to charge your car battery
Hi Genius Tinkerer, LED lamps can have a prism to accentuate the light output. I love watching your videos, good luck!
Cool, thanks for the tip!
Sir please pressure washer restoration
Very beautifull jab mashallha
I like this dude he shows it all mistakes an all great posting :-)
I am addicted to ur restoration videos.
What do u do with all these products after restoration?
I'm so glad you like all my videos. All these products are in my workshop.
Which model exactly is the car battery starter?
