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
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.
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
For higher voltage can We use voltage multipley circuit
Nice. 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

If I had put a voltmeter it would have been top,👍🇧🇷
thank you TARIQ LAB . . .. mabuhay !!!! jun mozo, davao city- philippines
Well done!
It is better to add a DVM (digital voltmeter) to your design.
Thank you,
Voltmeter added in my other designs
Esallamo 3alaycom nice and good work proftionall thank you very much teacher and good luck 👍👍👍
Thanks a lot Tariq bhai
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.

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❤❤❤
hello sir,,,, can you make a video,,,,,a backlight tester using a circuit of long tube light bulb ,, thank you
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
Yes I have seen thanks 😊
I am a new subscriber today.. I'll try to make one of ur project.. thank u and more power.. buenas dias
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 👍🙂
Great work.. but I hope you delete the singing clips from the videos you publish and settle for the music only 😘
Noted
How many volts out put of transfrmr.pl tell
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
How many amperes does the transformer have?And also the wattage of the resistor?thanks in advance
Transformer 1A resistors 1W
good information from Saad electric
Very Nice Job Sirjee......
Welcome
Nice video, thanks :)
Good 👍👍👍
Nice project brothers🙏
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
How to connect volt and ampere meter to this one.
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
Superb Project 👍👍👍👍👍👍
if I add a voltmeter to the circuit, can I use it as a zener diode tester?
Yes
Nice 👍🏻👍🏻 🇮🇳 Kuki 30|08|2022
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
thank you for sharing this with us!!!
Good 🎉❤🎉❤
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
Kreatif good
Good 🙏
Nice idea. Thanks.....

Amazing video, Thanks a lot TARIQLAB
Can you suggest me another bridge rectifier instead of this
U can use 4 diodes
Una pregunta las 2 resistencias son de 330 ohmios ??
Yes
@@TARIQLABcan we use other than 330 ohm resistor
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
Good Bhai Ji,👏👏👏👏👍
Is that correct or no?
Nice video.what is the wattage of two resistors used?
1/2 watt
@@TARIQLABhello sir cam we use resistor other than 330 ohm
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
Good
Super
Thanks
Sir transformer Amp..???
Are you sure this resistor is 330♎?
Color is invisible
Yes
@@TARIQLAB thanks,
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
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?
Can I use 220 Ohm resistor? It cause any damage?
No problem
@@TARIQLAB thanks for reply sir
Why you didn't Using digital volt meter?
Won't the current drop for each led that's driven by this?
Stay blessed 🙌
12 0 12- 1amp transformation aur 330ohms resistance use kiya lekin LED jalta nehi kyu.
Probe pe kitna volts hai 30se oper hona chahiye
Transformer kitne amp's ka hai ?
1 amp
Nice sir👋
Thank.... Let'snext brother
Nice work
Sir capacitor ka number bataiye please
Filter capacitor hai, 1000uf ya 2200uf 50v
sir what is the Value of condencer
1000uf 50v
The 👌 video
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™🛑
Yes like this one want digital volt meter in it
Wait for next video
@@TARIQLAB okay thanks 😊
capacitor vallue not mentioned
1000 or 2200 uf 50v
What was the value of capacitor??
2200uf 50v
Can I have the circuit diagram of it and the layout?
@@TARIQLABsir 12 0 12v 3amp use kar saktein ha I kya
ينفع محول 9فولت
Yes, use 33 Ohm resistors
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?
بھای آپ اس میں میوزک نہیں ڈال کرو اس سے آپ کو گونںھا ملتا ھے
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.
whats the cap size please
1000 uf 50v
يتعذر التعليق لا أعلم .
Sir Resistance value tell me
330 ohm
Thank you sir
👍👍👍
The Cool...
One question: and the Diagrama?.
Only diode capacitor & resistors, very simple
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
Won’t the Leds fuse
Safe for all LEDs
That resistors is not 330 ohms
In video may u see different colors
Transformer kitana amp ka ha
2A, ap 1A ka bhi use kar sakty hain
@@TARIQLAB 750 amp ka chal jayaga kya

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.
