Small & powerful flashlight for emergencies

[@MTS_IT]

to "partially remove the cheap look" - EXCELLENT! :D

[@GotaSir911]

Use 3 1W LEDs, placed on a metal heatsink and make the body out of an aluminum tube. Now you have an even more powerful torch with a good heatsink (add insulation or a handle cuz this gets hot)

[@JimbleBailey]

Thanks so much for this! I copied this project to modernize a dinosaur flashlight I loved as a kid, and now I use it when I take the dog out before bed!

[@Manu-nr1yt]

Didn't expect that this needs explaining on your channel but the LED voltage is not what matters. The LED current is what matters. The voltage for equal current will vary even between your 7 LEDs. So likely you overpower a few. The best way to drive those would have been to wire them in series and use a boost converter with a resistor in series to stabilize current. Edit: I also don't get why people still use 18650 without any fuse in series. If anything fails short, then this cell will happily drive 100A or more. If nothing breaks this current it likely catches on fire.

[@Sorin_DIY]

Hi. I know the current is important for the LEDs, that's why I recommended to add a resistor in series with the LEDs. I should have explained more about this (like I did in my LED Sign video or other videos with LEDs). I didn't add a resistor to this flashlight, because I wanted to stress test these LEDs to produce more light, at the expense of shortening their lifespan. But I did mention that adding a resistor in series will be better for the LEDs. About the fuse, yes, I should add one. I added fuses in almost all of my battery based projects. I was in a hurry to finish the build faster. But I did take a lot of precautions, I tested the battery and the modules, I sealed with glue and kapton tape the battery and all the joints and connections. but a fuse would have been better, I admit.

​@Sorin_DIY You know what this means Sorin? You'll just have to make another video. 🎉 Call it version 2

the hot glue trick for the charging indicator was simple but effective. cant wait to try for my diy projects

[@twotone3070]

I love the use of the hot melt glue as a light pipe for the LEDs.

[@liamburge463]

Sorin, just though you could add reflective tape to the inside of the led housing, unsure if that'd make a difference to the brightness though. Great project!

[@GuianLorenzo]

I now know how to remove the cheap look from my builds, thanks for the tutorial 😎

[@DJBriers]

Awesome. Keep making these awesome videos!

[@gheorghitaboboc1502]

Nice small flashlight!

[@techbarron7383]

hi sorin,im glad to see your video again with a bit funny and that we like, please next any project using super capacitor such as 500Farad

[@amansingh-ph7zz]

Hi sir please help me, i am big fan your work, I learned a lot,i have two buck converters szbk07 and lb07, on both of them current adjustment option does not work even on load applied, i even changed the cc pot with 100k precision pot .how to fix this?please its really impotent to me

[@gabrielantiligando9905]

I have a 180 and a 130 DC motor. What can I do with them?

[@JoshyMC_1]

Hey dude! Maybe I can request projects please? Can you make an automatic on emergency light? Like you will use TP4056 module can you do it please! Please Respond ill be waiting...💗❤

[@Sorin_DIY]

Hello, I already made an emergency LED sign video - kzbin.info/www/bejne/bKbLfoKQiryIiNk

[@CTCTraining1]

Great project and that trick of reducing a section of pipe to make the connection is a very cost-effective one 😀👍 I’m interested to know how clean the supply is from the new buck converter for use on more sensitive projects. Happy Christmas Sorin (and your assistant 😸)

[@zamSEG]

great video sir. any chances for future video on making this setup using cree t6 led?

[@Sorin_DIY]

Thanks. I have a 10W cree LED, I will probably use it in a future video.

[@zamSEG]

@@Sorin_DIY you're most welcome and look forward for that to happen. have a great day and thank you for quick replying my comment.

[@kennethpaulcalangi4122]

I love this build. very practical. any SMD LEDs (for smaller flashlight project) that's efficient that you can recommend aside from what you used for this project?

[@Sorin_DIY]

Hi. I haven't tried smaller LEDs. but these are very good: s.click.aliexpress.com/e/_De689Hf I used the 5W and 10W types, they are good but produce a lot of heat. they need a heatsink.

[@hanymagdy2095]

Good morning dear, if you want me to set the tp4056 to 2 amperes, what should I do? Thank you.

[@Sorin_DIY]

Hi. you can watch this video: kzbin.info/www/bejne/joGmemlnqr6UapY

[@tcirit]

Dear Sorin, did you make any modifications on your Opus charger which it needs (for resistance, etc.)? Do you have any recommendations for this? Thanks for your this video and your future answers.

[@Sorin_DIY]

Hi. I haven't modified the Opus charger. It can only charge/discharge cells and measure the capacity.

[@tcirit]

@Sorin_DIY I know, but there is a cable mod for the resistance mesure correction. Thanks for your answer.

Sarbatori fericite!

Can you do a video of led video light making ?

[@L-Coder]

Please make a diy flashlight using button leds(which also operate at around 3 volts) with heat sink and a conical reflector using the mirror like reflective sheet which can be found inside broken mobile lcd screen. Please!!!!!!!!!!!❤❤❤❤ Use around four leds of 2 or 3 watts. And two or more batteries. That would be more powerful.

[@xtech2482]

de unde faci rost de aceste module? in special amplificatoarele audio, care le ai folosit in alte video-uri. sunt disponibile in romania, sau de pe aliexpress?

[@Sorin_DIY]

Salut. Aproape toate componentele le iau de pe aliexpress. am pus link-uri cu piesele in descriere la fiecare clip.

[@Boda.Attila]

@xtech2482 Salut! Poți găsi o mare varietate de module și componente în magazine online românești, cum ar fi ardushop(punct)ro, tehnoelectric(punct)ro, cleste(punct)ro, contactelectric(punct)ro, hobbymarket(punct)ro, conexelectronic(punct)ro si multe altele, chiar si emag. @Sorin_DIY Știu că KZbin nu "apreciază" linkuri externe, sper să nu îți cauzeze probleme acest comentariu.
