thank you. Thank you for taking away such an old flashlight. It's a National (currently made by Panasonic) light. In Japan, it used to be a staple item in most homes. from Japan
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 😊
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
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
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.

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.
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).
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!
@@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?
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 👍🏻
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
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 👍🏻👍🏻👍🏻

I'd imagine its because the washing powder granules might have a slight abrasiveness to them to begin with which might help move dirt easier where as the washing liquid relys on its degreasing potential. just to add after working on my car if I don't have any proper stuff to get oil and muck off I will use washing up liquid with a spoon of salt or sugar that helps greatly to remove the dirt.

Good Restoration Flashlight made in Japan 👍
He really likes your work. You are creative👍🏻👍🏻✅
I want to know which country are you from?
You keep my mind at ease good sir, never stop!
Thank you!
You restored a dirt cheap plastic flashlight 😐 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
You.re best 👍👍👍👍👍
Thank you!
Nice video continue 👏💯💯💯💯
Good ideas and information 👍
Excellent👍👍👍 . Thanks for sharing
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.
New jump start as gift👍

Charging will be a problem with 1s4p ( no any BMS & charging module to keep the unit safe ) . Using Buck Converter is a best solution.

Hello. Great project and beautiful restoration, I liked it👍
Advanced Congratulations for 500k 🥳
Great work👍
Thanks ✌️
Happy 500k in advance 🎉
Thank you in advance :)
Good work or aise video banaiye
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?

Hi Genius Tinkerer, LED lamps can have a prism to accentuate the light output. I love watching your videos, good luck!

Nice video though 👍
Great video sir l love your all videos thankyou very much for this video 🙏🙏🙏🙏
VERY GOOD VIDEO!!!!!
Thank you very much!
Excellent emergency flashlight rechargeable and everything?
Better than when it left the factory.👍👍
thank you teacher
Beautiful Work.
Why don't you use 1s battery . It easier and more effective . Your skill is so good
good job👍👍👍
Excellent project. I liked it ! My idol !
Another great job ❤

I think it's a modification, not a restoration, but I like this one.
Yes, I'm glad you like it.
Perfect 👍
good hit🇮🇳👍👍 Kuki
What emitter did you use? Should have used a warm emitter, around 2700K to keep the same color temperature as the stock light.
I like your flash light nice you convert to LED and rechargable
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
Good job, I Always watch your new video, I am From Indonesia, sorry if my english so weak
could you make a car starter kit from scratch?
LOLLLLL, he see less light, the finaly he changed all anything, that's amazing
Omg! i have one of these they are like headlights of a car
Is there a reason you always use washing powder when cleaning the plastics, rather than a dish soap liquid?
I'd imagine its because the washing powder granules might have a slight abrasiveness to them to begin with which might help move dirt easier where as the washing liquid relys on its degreasing potential.
just to add after working on my car if I don't have any proper stuff to get oil and muck off I will use washing up liquid with a spoon of salt or sugar that helps greatly to remove the dirt.
Like for the video. Please tell me, what kind of cream is this? Write his stamp, please.

14:57 but reflector is heat should reduce volts at buck convertor 4.2 to 3.3.-3.5v led will heat less
Excellent job sir .Can you please provide for me the link where you buy this big reflector thank you.
That battery pack doesn't fit, let's make another one... LOL 🤣
Good Job
