Great project! Which should be the best components values for 5 fans and 12v? Thanks!

[@electromaticspark8187]

Thank you. For 12v you can use the same value components it can work fine.

[@neilcrompton3488]

Would this be suitable to reduce the speed of a dc motor in a sewing machine which draws power from a 12 volt ac plugpack @ 1200 milliamps?,or are there changes to resistor value needed? Sewing machine runs way to fast & needs a speed reduction.

[@Naitik9876]

Pnp or npn transistor

[@akbarmohammadjafari3371]

Hello, if we use 220 volts, what transistor should we use? Thank you

[@electromaticspark8187]

Hi, if you want to use 220v then you have to connect Bridge rectifier circuit which will convert 220v to 5v. This circuit cannot take more than 9v. I will suggest you to simply use 9v battery. Thank you.

Please tell me bro I can use 100kb potentiometer from old radio

[@electromaticspark8187]

There is no such potentiometer it is 100 k only check properly

[@alwayssmile-8793]

OK bro it is written as 100kb I thought that it was 100k but it was smaller than yours so that I asked thank you bro for replying bro 😊😊

[@electromaticspark8187]

Welcome bro and thanks for watching

[@ewaanhyzin6764]

Is this suitable for 10mtr 12v led strip light.??? I mean led take more current .so is this suitable for 10meter led light dimmer circuit

[@electromaticspark8187]

You can use the circuit but you will need more voltage as you are using 12v led strip

[@kavitakumari692]

Yea circuit kitne amp tak work karega

[@electromaticspark8187]

You can use 9 v battery

[@WebDepthMviewsyearsago]

Dont use 555 or 775 or any other motor its an led dimmer this circuit can only control speed of this cpu fan because cpu fan doesnt take more amp than other if u use another motor the transistor will blow up its current capacity is only 500ma

[@nanicreations2472]

@@WebDepthMviewsyearsago tq very much

[@jonasfelipe777]

Did you calculate the fan`s current? I need this information to my 6V dc motor, please.

[@electromaticspark8187]

You can use it for 6v motor I am using standard 9v battery

[@allen7789]

Why did you use 10k resistor and 100k potentiometer?

[@crowsandcrown1431]

Can this circuit control two pc fans and it will be Ok if it run 24h a day?

[@electromaticspark8187]

I will not suggest to run 2 fans on one circuit. But you can run this circuit for 24h with low supply.

[@adv.anandanirmale9653]

Can you supply this 12vt cooling fan regulator, in mumbai

Can we do it with 10k pot?

[@hirukaleenath1679]

its working but transistor is getting too hot 🥵

[@electromaticspark8187]

How much power supply are you giving?

Can I use 22k register instead of 10K

I guess problem is in voltage input I am giving 9v don't go beyond 12v.

@s s Hi, do you have a diagram to build it? (or and already made if there is some to buy?)

[@AndyAdlaon]

Its work but transistor its so heat my goodness

[@electromaticspark8187]

I guess you are using high voltage

[@abhijitc215]

I am made this circuit but This is not working.

[@electromaticspark8187]

Watch the video again you must have miss something

[@abhijitc215]

@@electromaticspark8187 no i am not missing any parts. I am use 12V DC (Battery Drill Motor) motor but this is not working please tell me what is the problem. And tell me working voltage of your circuit.

[@electromaticspark8187]

I have used 9v battery to supply the circuit and as you are using 12v motor try different potentiometers it will surely work 👍

[@abhijitc215]

I used 50k Potentiometer.
