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
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.
@@gear_show You might be interested in my new video. It is making a small gear puller for small electric motors. th-cam.com/video/UC-6KvAKliQ/w-d-xo.html
@@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?
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
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 😊
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!
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.
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 👍🏻👍🏻👍🏻
Waste of materials, why do you put a buck converter to reduce 12v to 4.12v to feed the led?? Why do you make a 12v lithium pack? You could make a 4.2v pack litiuhm and a simple tp4056 to charge the pack
Thank you for asking me, there are few reasons I did that. - 12V battery pack is faster charge that 4.2V - Buck converter provides stable voltage to LED - I can charge them with the same charger of my power tool
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
I don't understand why you didn't put the orange batteries in a square pack rather than making 3 tubes like the original ones. I think it would have fit, you just needed longer wires. Nice restoration though

Good ideas and information 👍
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?

Very nice G.S... Thx for taking us along...
Good work or aise video banaiye
Great work👍
Thanks ✌️
Oh, I've seen same one at my home 25 years ago.
New jump start as gift👍
Great job 👍
i,d really like japanese flashlights!
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.

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

Its more than perfect restoration.
VERY GOOD VIDEO!!!!!
Thank you very much!
Simple, easy and fun project. I enjoyed watching this one. Thanks!
Ok
Nice video though 👍
Good

Good Job, verry nice.
Thank you very much, I have been waiting for you eagerly and have benefited from your work in remanufacturing a flashlight
Nice 😊 brother
Thank you so much 😀

Hello. Great project and beautiful restoration, I liked it👍
Were are you from, Bro?
I am from Indonesia.
Good job. 👍
I'm from Cambodia, thank you!
Perfect 👍
Amazing work
Thanks again!
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!
very nice
I like this dude he shows it all mistakes an all great posting :-)
Beautiful Work.
Your videos are so inspiring. I hope to be able to do some of that work in my free time in the future.

Thank you in advance :)
Excellent emergency flashlight rechargeable and everything?
What emitter did you use? Should have used a warm emitter, around 2700K to keep the same color temperature as the stock light.
Sir please pressure washer restoration
good job👍👍👍
good job
Jaaaaaaa...Muy Bien my Friend...Saludosss ji ji ji
Obrigado pelo ótimo vídeo
nice i love ur videos
Why don't you use 1s battery . It easier and more effective . Your skill is so good
You deserve this gift
congratulations
Nice video continue 👏💯💯💯💯
Even a child can restore this flashlight
Bullshite alert 🇬🇧👍
*What is the need of using buck converter U could hav connected the cells in parallel instead of series to get 4V output for the LED light*
I build 12V for fast charging reason.
@@gear_show fast charging is also possible @4V, This is waste of energy in Converter
Like for the video. Please tell me, what kind of cream is this? Write his stamp, please.
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.
