[@dennismikha7541]

Cannot believe how lucky I am that found this video. I had a hundred of smd leds and I have managed to soldered 5x4 matrix on pcb board..and didn't knew how to finalise this project. Smd flash leds are blinding thou and maybe some heavier resistor will be required coz overvoltage cause overbrightness also heat and sometimes even smoke..xD

[@Faithinchrist-TZPPM]

superb 😎😎😎😎😎 ....... great job and thanks for your video ..... I requesting like this more videos................ .

[@BrazilianGaucho]

Nice job. I was looking for an extra simple circuit exactly like this one. Thanks a lot. Just one small observation: if you glue the components, then you won't be able to replace them when they burn.

[@goodtech1]

Yes, that is true. this is the reason i use hot glue to attach the components as it can be easily separated just by using an hot air hair dryer.

[@BrazilianGaucho]

Indeed, I hadn't taken that characteristic of hot glue into consideration.

[@venkataprasanth4923]

it was very nice

[@swiperfox3145]

What voltage rating are the LEDs? Why do we need the 100 ohm resistor? ==================== In a motorbike shop... I bought a continuous 50 LEDs @ 12 volt rating in parallel connection. I use 18 volts (two 9-volt batteries in series) to power it. Its super bright.

[@shadowmean1550]

Awesome build dude, i'm camping next week and was looking for a cheap efficient flashlight like this one, it is just perfect, do you think that in total darkness in a forest it will help me move short distances? just like ten meteres, from the pitfire to the barracks or a river... (sorry for bad english)

[@goodtech1]

Yes, it does give nice light although i am not sure about power backup. Do keep some spare batteries.

[@metallicrock5946]

just buy a $5 torch

[@abhijeetsinghchauhan34]

Humberto Teixeira I think if use some more LEDs the it should definitely help you a lot

[@ccv3237]

[@viratkohli644]

its cool

[@goravgzb6084]

i think there are some of different sizes big small rectangle round shaped of leds in market with different volts can u suggest which one would be best

[@goodtech1]

The LEDs comes with various voltage, current and colour specifications. All LEDs will work subject to change in supply voltage. The one's i used are white in color, mm in size, 3v operating voltage and 30mA operating current.

[@bhushanbhosale3161]

What if i use more led lights and keep the rest components same the battery and resistor will it work??

[@bhushanbhosale3161]

Hey plz reply

[@xtremocpj]

Could you tell me what is the luminous intensity or luminous flux of your flashlight?

[@SATHISHKUMAR-ek5cg]

Great !!! But why did u covered the name of the battery with the black tape?

[@goodtech1]

Just to make it look nice.

[@mcnagynorbi]

Product Placement :D

[@blavard3509]

Sometimes your time is worth more than a hack. I appreciate the effort and thought about making one myself. Then I got my Harbor Freight sale advertisement. You get a 24 bulb LED flashlight free with any purchase, batteries inculded.

[@sanjaysutar8811]

Please make this flashlight with on/off switch

[@hannahadkins6190]

How many lumens would you say?

[@deloydjhansen8766]

Where did you get the small hand drill you used?

[@goodtech1]

It is Hand PCB drill available on local tool shops, you can use a needle as well or you can also watch my mini USB drill video to make an electric PCB drill at home (kzbin.info/www/bejne/aWrbgZt_a7qnpMk).

[@bestamerica]

[@sonujack2763]

bj

[@cc-xu3mc]

so if i build mine with more led lights do i need to use another resistance?~~cc

[@goodtech1]

Yes, you will have to calculate the resistance value considering the input supply and power consumption of the connected LEDs.

[@jeffersonalberto1916]

How many days does the battery will work?

[@SangGenerasiMuda]

nice bro...

[@gianfrancopetitti]

built one with switch on/off, but mine is not so powerfull... maybe my LEDS are higher of voltage or what? the light that come out is comparable with the light of the cell screen. :(

[@mshiblee1617]

hello, why need resistor 100ohm.? I want to make ir flaslight, if I use ir led instead of normal led with same circuit diagram then is it work? what resistor should I use? pls reply.

[@goodtech1]

The LEDs are very sensitive to current. So a resistor is connected in series (that acts as a current limiting resistor) to protect the LED from damage and increase its operating life. A 100 ohm resistor will work fine with an IR LED as well.

[@ferdieronquillo9823]

What is the value of the resistor?

[@someone1924]

Nyc

[@akshay9619]

Which tripod do you use

[@rbiocorporation9536]

Unfortunately, you neglect to mention exactly what kind of LEDs to employ. Seeking to make a simple proof of concept and had hoped your video would address the LEDs used in making a "super bright" LED light. Not all LEDs are equal. Not all are extremely bright. More information would be helpful, if you have it. Liked how apparently bright these white LEDs are...just unclear about the specifications.

[@cheedellaeswari5456]

Card board is a insulating material how it conducts electricty

[@goodtech1]

No, it doesn't but i have connected LED legs to eachother and they conduct electricity.

[@SolehKamarulazizi]

Can the 9V battery replace by solar panel and the LEDs light up back the solar panel?

[@goodtech1]

Yes the battery can be replaced with a 3 Watt solar panel.

[@aashirsiddiqui5203]

oh wow that's a good idea! Then that can be a free energy flash light! But the solar panel should be efficient. It should generate more electricity by using less light.

[@parmarronal4776]

hello, what thing u use for stick ? is it glue?

[@goodtech1]

Which stick?

[@boiling94]

what the capacity of that resisiter's....? 100 ohms or bigger than .....? is 100 ohms resister enough for these six led lights...?

[@diablo09090909]

Yes. It would suffice. More information here --> www.evilmadscientist.com/2012/resistors-for-leds/ (that's not my blog nor am promoting it)

[@moss8448]

On Off switch would be nice....I know I know...just unplug the thing

[@ramdasbangar3093]

wow

from where you bought drill

[@KennethNicholson1972]

[@Coxfame]

what does the 100 ohm resistor for?

[@goodtech1]

It is a current limiting resistor to protect the LEDs.

[@mysterywalidunia5663]

we can make a 2 lights or not

[@sheemu87]

is it aluminium foil used to wrap food???

[@goodtech1]

yes

[@masterstroke6022]

how many ohms resistor i will need

[@goodtech1]

100 ohms

[@zeeahmed3123]

+GOODTECH - Creativity and Science can we use 300 ohm's

[@goodtech1]

Yes, you can but LED will glow bit dim (Beacause current in each LED will be 10mA) and they will not be bright enough. With 100 ohm resistor, each LED receives 30mA of current (operating current of LED) when source input is a 9v battery.

[@zeeahmed3123]

+GOODTECH - Creativity and Science ok thanks:)

[@BaljeetKaur-ke1uq]

we use any colour led or not

[@goodtech1]

Yes, any colour LED can be used but a white LED works best for a flashlight.

[@BaljeetKaur-ke1uq]

thanks

[@BaljeetKaur-ke1uq]

it is good flashlight

[@YasirKhan-yv3zj]

what the machine your using to hole please....

[@goodtech1]

I used a Hand PCB drill.

[@JackArn123]

what LEDs do you use and what resistor values ? thankyou :)

[@goodtech1]

5 mm white colored LEDs and a 100 ohm resistor.

[@mshiblee1617]

if I use 5 mm IR 12 led then what resistor should I use?

[@goodtech1]

what will be the input power source??

[@windgamerz2800]

[@mukeshbanerjee6943]

Sirius LED set karne ke baad LED Ke Piche ki taraf aapne kya Lagaya wo to nahi bataya.... Please reply sir

[@goodtech1]

I juts connected a 100 ohm resistor, a battery connector and then covered everything with a Black tape.

[@bossbosss8081]

What is that silver sheet name

[@goodtech1]

It is just a food wrapping aluminium foil used in kitchen.

[@prittamkumar4546]

acha hai

[@suzanfernandes4221]

for how much time does the battery last

[@goodtech1]

I haven't calculated the exact time but i am using a single chinese 9v battery since last month and it is still not dead.

[@avaholiday2236]

can u list the materials n how long does this last

[@goodtech1]

Cardboard, few LEDs, 100 ohm resistor, 9v battery and a battery connector. I haven't calculated the exact time but i am using a single chinese 9v battery since last month and it is still not dead.

[@shalinikumari6095]

what is the amount of resistor used?

[@chinmaykudtarkar896]

can i connect an OTG mini usb to it

[@goodtech1]

Yes, that can be done. But the light will not be very bright at 5v.

[@MCruz-fb9dv]

Hi can vape battery use for making flashlight? Just asking 😂

[@diablo09090909]

Yes. But keep in mind, vape batteries are generally of more current than the one he used. So you would need to scale up on resistance based on the battery and the number of LEDs used..

[@MCruz-fb9dv]

ok....thank you :)

[@MCruz-fb9dv]

hope someone make it
