So lovely to learn .......so nice music, which is flow ing and understand your new knowledge......so....
You are doing great job
Thanks again for your help
What is the capacitor value? If you provide the components list it will be nice.
1000uf 50v
For higher voltage can We use voltage multipley circuit
Thank you so much! I can not wait to start setuping. I want to create original soft for comrcials and shows alongside my many other
but how the voltage value change automaticaly ?
Due to the resistor,
@@TARIQLAB but the resistor value is fixed bro , can you explain in more details , thank you
Thanks for your video! Can I test a 94v strip with this set up? If not what is the highest voltage I can go?
U can test start to half strip or single led, otherwise u have to use higher transformer 60v
Very Nice Job Sirjee......
Welcome
How many volts out put of transfrmr.pl tell

de nada muchas gracias
Nice. Thank you.
thank you TARIQ LAB . . .. mabuhay !!!! jun mozo, davao city- philippines
Can i use a 24V trafo without a centerpin?
Yes
Good 👍👍👍
so i understand that the voltage range is 3to 32v?
how can i make with higher voltage range?
what about amp? how i control the current
so is this setup can work with powerful led 30w or higher?
i need to build one that i can use it to test single leds or strip with any voltage upto 100v for example and i will install voltmeter and amp meter to know the voltage and current suitable for the led is it possible?
Increase the value of resistors
@@TARIQLAB if i increased the resistance what will happen?
if I add a voltmeter to the circuit, can I use it as a zener diode tester?
Yes
Any white led draws 20mA maximum but this ps you build, can give 45 mA current at 34V (ideally 24Vac transformer gives 24*1.41=33.8Vdc) output and with totally 660 ohm serial resistors that this current is harmful for ordinary single led.
How to connect volt and ampere meter to this one.
What is the value your capacitors?
1000uf 50v
is it ok to use GBL 405 BRIDGE rectifier IN PLACCCE OF BGL 406 rectifier
Yes
can we use 32 0 32 transformer?
Use only two wires one center other side
How many amperes does the transformer have?And also the wattage of the resistor?thanks in advance
Transformer 1A resistors 1W
Is it possible to add a DC volt and ampere digital display in this circuit. If so kindly provide the sketch for this addition in the circuit. Really an interesting and useful circuit you have uploaded. Thanks a lot.
Visit my channel
Sir what is the value of condenser
1000uf 50v
Una pregunta las 2 resistencias son de 330 ohmios ??
Yes
@@TARIQLABcan we use other than 330 ohm resistor
Esallamo 3alaycom nice and good work proftionall thank you very much teacher and good luck 👍👍👍
Yes I have seen thanks 😊
Nice video, thanks :)
Can I use 220 Ohm resistor? It cause any damage?
No problem
@@TARIQLAB thanks for reply sir
hello sir,,,, can you make a video,,,,,a backlight tester using a circuit of long tube light bulb ,, thank you
Can you suggest me another bridge rectifier instead of this
U can use 4 diodes
Tariq bhai me isme digital volt meter lga skta hn? Agar haan to kahan or kese. Mere pass 2 wires ka digi meter he
Jee laga skty hain , dono resistors ail sath positive side pe laga den black probe ko direct negative pe voltmeter ki negative bhi, red prob aor voltmeter ki positive ko dono resistor ke baad la len
@@TARIQLAB JazakAllah bhai. Me kr k btata hn
If I had put a voltmeter it would have been top,👍🇧🇷
Nice project brothers🙏
I´m a bit confused cause the colours of the resistors you are using doesn't seem to indicate 330ohm value do they ?
330 ohm
Well done!
It is better to add a DVM (digital voltmeter) to your design.
Thank you,
Voltmeter added in my other designs
Higher voltage Led series will not work with this output voltage like the 9 watts led bulb with 9 Volt led each so total 80 volt required
I think your slm videos are educational. Thank you. I have a question. I don't want to spend on my cordless drill and buy a new adapter or tarsformer. It's expensive. Can I convert my 12V, 2A adapter to 14.6V and 20A, I need your information, thanks
It's impossible. The power of your present PS is 12*2=24W. Whereas you ask 14*20=280W. It looks like to hope a child 5 years old to carry a 100kg weight. You should buy a more powerful PS.
Sorry, this section is Turkish:
Sonradan farkettim, soru soranın adı Türk olduğunu kanıtlıyordu. Herneyse, yukarıdaki lafın özeti 3 kuruşa 5 köfte olmaz. Sen herhangi bir güç kaynağının akımını veya gerilimini artırıp azaltabilirsin ama gücünü yükseltme olanağın yok.
@@gundogankazanc9241hello sir can we use other than 330 ohm resistor???
@@asifshahsyed422
sure. that resistors limits load current but under constant voltage.
according to differences of the work or test, you can use vary values. if the R is big so the current goes lower and R is less, current is much more than first one.
i always prefer less current not to break down something
@@gundogankazanc9241 thank you
Kreatif good
I am a new subscriber today.. I'll try to make one of ur project.. thank u and more power.. buenas dias
good information from Saad electric
Are you sure this resistor is 330♎?
Color is invisible
Yes
@@TARIQLAB thanks,
Good 🎉❤🎉❤
خیلی عالی متشکرم فقط مشخص نشدچیپLED هم روشن میکنه؟ اتصال کوتاه داره؟ویامیشه ولت مترنصب کردکه ولتاژهرکدام لامپ رابشه دید یانه؟ممنون میشم اگه جواب بدید سپاس❤❤❤
Good Bhai Ji,👏👏👏👏👍
Thanks a lot Tariq bhai
Superb Project 👌👌👌👌👌👍
Sir transformer Amp..???
Have a nice day Mr. Tariq. Honestly, among the videos I watched on LED testers, it was your LED tester that I chose to do. But the transformer I bought is 18-0-18 Volts and not like your 12-0-12 Volts transformer.
Question: do I always keep the same values
-capacitors (50V, 1000 microfarads)?
- the 2 resistors (2×330 ohm)? Thank you to answer me to start testing my LED.
Increase resistors to around 420 ohm and better to use 63v capacitor
@@TARIQLABthank you very much Mr. Tariq.
Your brother from Tunisia.
No, less than 60v no problem
Good 🙏
Transformer kitne amp's ka hai ?
1 amp
12 0 12- 1amp transformation aur 330ohms resistance use kiya lekin LED jalta nehi kyu.
Probe pe kitna volts hai 30se oper hona chahiye
Nice idea. Thanks.....
thank you for sharing this with us!!!
Why you didn't Using digital volt meter?
Won't the current drop for each led that's driven by this?
Is that correct or no?
Great work.. but I hope you delete the singing clips from the videos you publish and settle for the music only 😘

Super
Thanks
Sir if I put a volt meter will it show the vote
Yes , normally it will show total volts 48V , but when u check led will show the eld voltage.
Can Sir Resistor Cotter Watt be used?
Nice 👍🏻👍🏻 🇮🇳 Kuki 30|08|2022
Bạn cho hỏi ,tôi có vol kế 3 dây ,vậy hàn vô đầu nào và như thế nào
+ mắc cực dương tụ - mắc cực âm tụ, dây chuẩn thứ 3 sau điện trở
Sau điện trở mà ỡ chân +hay - ,cám ơn bạn nhiều
37V/660ohm=0.056A=56mA Too much current.
The resistor needs to be increased to 2k ohm.
Then not possible to test 32v led backlight strip. With this arrangement u can test 3v-32v led
Why use resisters?you use 12-0-12 .bridge that means 24v coming .that time you use resisters drop the voltage .how to check led lights and black lights ? Not show perfectly.
Resistors drop voltage and amp according to load
since there are 36 volts at the tip of the tester, why doesn't the led burn?
I used Resistors , voltage and current drop
@@TARIQLABtank's
I built this project. worked perfectly. I was looking for a led tester. Thanks.

Won’t the Leds fuse
Safe for all LEDs
The 👌 video
Sir Resistance value tell me
330 ohm
Thank you sir
Good evening Mr. Tariq Thank you, I have already built an LED tester of this type, it works properly, however I still have a few questions:
1- Is it possible to get rid of the capacitor? If not, what is its role in this LED test?
2- Since we used a diode bridge which rectifies the alternating current into direct current, why then use a transformer since the diode bridge is enough when we can weld two diacs between the positive and negative terminals of the diode bridge. Thank you.
Capacitor is a filter capacitor to smoothing the DC voltage.
IJust be seeing this connection
Would you please draw it with another of thanks
Nice video.what is the wattage of two resistors used?
1/2 watt
@@TARIQLABhello sir cam we use resistor other than 330 ohm
whats the cap size please
1000 uf 50v
Sir capacitor ka number bataiye please
Filter capacitor hai, 1000uf ya 2200uf 50v
Input 220 v output...?AC
12+12=24v ac when converted to dc 36-40v, its 12v center tapped transformer, don't use center wire
@@TARIQLAB thnks ❤ brother
ينفع محول 9فولت
Yes, use 33 Ohm resistors
Nice video🙂👍, i want to ask. What will happen if we accidentally short positif probe and negatif probe.
Will the capacitor explode or the transformer burnt?
Nothing, may be resistors blow if u short for some time
@@TARIQLAB thank you for your information 👍🙂
Stay blessed 🙌
there's absolutely no way you're going to test single leds with 24v they'll blow up. some of them are 3v or less
Why i used resistors
Yes like this one want digital volt meter in it
Wait for next video
@@TARIQLAB okay thanks 😊
That resistors is not 330 ohms
In video may u see different colors
بھای آپ اس میں میوزک نہیں ڈال کرو اس سے آپ کو گونںھا ملتا ھے
Resistor ?????
330 Ohm
One question: and the Diagrama?.
Only diode capacitor & resistors, very simple
An LED tester that tests SINGLE diodes uses a 9 Volt block battery , with a 680 Ω resistor in series with one of the probe leads ... portable , for use in your tool bag ! ! ... ( tried - n - tested ) ........ DAVE™🛑
Put led meter also

Ерунда. А как супер прибором этим узнать на какое напяжение светики.
он не предназначен для постоянного использования, только для проверки, работает он или нет. резисторы снижают напряжение и силу тока, чтобы можно было тестировать светодиодную ленту от 1,8 до 30 В.

36 v damage to 1.5v led
Resistor will drop voltage and amps, all led tv use 90 to 180v for 32v led strip how??? If u see led tv circuit u can see a set of resistors using same method.
Open a led bulb disconnect leds and check voltage.
