[@dimitrisking7590]

Hello, is it working with 33Volts input?

[@ramanarao32]

kiyani ji nice video....does R3 gives short circuit protection also ?

[@janyalom-oj9ef]

my like your channel

Sir what can I use instead of 470k and 0.1ohm 5w resistor?? Plz help

[@sasanduperera672]

If I connect 2 transistors in parallel can I get 5 amps

[@mangeshkoyande9952]

Require 24 v dc dimmer circuit, can u show it ?

[@siddiquishoaib7929]

can we increase the current capacity?

*Is the Bell for notifications available on mobile devices?* I am subscribed and I’m using an iPhone X.

[@KiyanisLab]

yes bro bell is available on mobiles

[@Deep_Thoughts99]

What about short circuit? Is this safe?

[@nammon7380]

👍👍👍👍👍 Do you have the layout on the pcb?

[@kdcreativity6201]

Sir please tell me how you make that type of circuit diagram 🙏🙏🙏🙏🙏🙏 please please please

[@manoochehrsadighazar1857]

Output voltage not stable . I test with 300ma 12v. It drops to 11.66v

[@dejanvuletic248]

Can I use transforer with 26V output and Graetz recitfier as a input for this project?

[@KiyanisLab]

yes you can

[@sunilkumarr6254]

how to connect the display unit

[@ThememoriesIII]

why use 0.1 ohm resistor to serial a load this for set the current ?

[@KiyanisLab]

to limit the current

[@allanmanaged3187]

So without further ado --> advert and intro lol

[@MuhammadAli-wo5lt]

Wht You didn't tell about the input voltage?

[@user-sl4cc9in5o]

❤ Hellow bro🎉 Can you upgrade thin module in 24V 500A 😢😢 Please reply me 😢

[@noobaqgaming2112]

I can't find it 2sd1040 transistor what I use in alternative please tell

[@KiyanisLab]

2sc5200 or 2n3055

Hi bro Can you make a project by MH-10(AT-09)🙏

[@KiyanisLab]

Yes I can

[@sunilkumarr6254]

please attach the pcb lay out with out gerber file

[@amitghosh6966]

The third diagram file is not downloadable

[@ohmware2020]

how can i add short circuit protection to its output?

[@KiyanisLab]

have made video on short circuit protection you can use that

[@flyingfox8072]

With lm317, you can't get 0 v. Minimum is 1.25v.

[@KiyanisLab]

yes you can

What is max input and out amp ?

[@sanjeevsanjeev3068]

Rrrrrrrrr

[@Deep_Thoughts99]

What is the purpose of Lm358 in this circuit?

[@KiyanisLab]

current limiting

Sir please kab se kah rha hun water level controller with dry run And source tank without arduino microcontroller🙏🙏🙏 using ic ULN2003, 2803,2004,PLEASE SIR BHAI KI BAAT MAAN LO.... AND REPLY ZAROOR DENA😞😞

[@msana4420]

0V? YOU CANNOT ADJUST TO 0 volts!! YOU DON'T GET TO 25V. Show the output ripple when current limiting. It's going to be horrible!

[@Doilathe59]

is looking for a schematic diagram of a natural source circuit, and he finds him making a video as a source circuit

[@sabapathi.ssabapathi.s9738]

Bro how to stable output voltage? Plz upgrade ur circuit.

[@KiyanisLab]

Ok next time

[@Billrad71]

I love how you do your presentation! I'm just kind of a... Let's just Say a dumbass that don't know a cathode from a anode that likes to play with stuff like this. Can you expand my knowledge a little please?

[@KiyanisLab]

on a diode cathode is the pin with from the side which has line and from cathode negative signal goes in the diode and come out from anode

This is really cool. You have to totally vlog with Bad Friends! Their vids low-key reminds me of Danny Duncan mixed with Faze Rug!
