- Make a mini LED torchlight that can use with any power banks or any USB output.
it is very bright but uses low power .so it can last for a long time.
and it is made with epoxy resin, so very hard and durable. Наука
Good work 👍
supar good wow nambar 1.
What is circuit diagram?
sir agar 2 led ac 220 v me chlana Ho to kitna ohm rsisten lagega an d led smd kitne v /ma/ and aap Ye jo gone uj kiye hai kiya bajar me mil jaye GA
1k ohm bro
What resistor should i use to glow this 1w led on 12v?
use a 100-ohm resistor. if you use 1/4 watt resistor then it will heat up very bad, so instead use a 1-watt resistor for every LED.
Wonderful
Sir resistor kahan soldering krnay hn negative side pr ya positive side pr thik se nazar nh aya
koi bhi side chal sakta hai bro.
Ek batter se led bulb l
Bina hetsing bena a led light galgawga BHAI
As you r showing which side of soldiering have u done +=+ +=- -=-
All LED's plus terminals are combined. As well as minuses.
Resistor rate?

THANKS!!!!!
90mA x led
what is the watt power of 22 ohms resistor
1/4 watt
can i use Resistor 47K Ohm 1/4 Quarter Watt for this project
@@milan72 i have ordered 22 ohm 2W 22R Metal film resistors by mistake
. will it work ?
@@adriantokarczyk8445
It will work. Its just of bigger size.
Please 6 led diagrams show
What is the name of glue
Abdullah Ijaz
Z&P epoxy resin.
Milan Kundalia
Can u give me link to buy
Abdullah Ijaz
Sorry but I bought it from local store.
You can find this or similar from SPEAKER REPAIRER.
Nothing
can we use glu gun instead?
Series or parrel
Parallel
4 resistors used one for each LED; parallel connection to power.
Hii
Backup time plz reply
For 10000 mAh power bank it will last about 8 to 10 hours
use glue gun to cover bulb

Vai light ta gorom hoye glue gole jay
Ye glue nahi h its resin
Video mein mention krna chahiye tha
Show the specifications of soldiering just showing registers
This is too much unnecessary resistance for 5 volts . mostly you are supplies these LED's with less than its half power and mAmp.
yes, but it's for longer battery life and not generating lots of heat.
1k or 3k3
its 22 ohms only
