That's an interesting science project. If I were still teaching, this would make a great lab!

Can I use IR F540 mosfet instead of STP16NF06L mosfet?

[@Science.Buddies]

The IRF540 has a higher gate threshold voltage than the STP16NF06L, so you may need a bigger battery pack (like 4xAA instead of 3xAA) for the circuit to work properly.

Can I use IR FZ44N MOSFET?

[@Science.Buddies]

It looks like the IRFZ44N, like the IRF540, also has a higher gate threshold voltage , so would also require a bigger battery pack, but otherwise the project should work.

@@Science.Buddieswhat should the voltage of the battery be for it to work?

[@custodioarmindogungulo8465]

Can you please help on numbers? I mean capacities of all the elements, there are only for resistors. Thanks.

[@shamsulhaque5848]

Thanks for the project bro. I'm using your idea & participated in science project competition, let's see👀 if I get the prize or not.

[@syclone_]

how did it go?

[@kavyajoshi5921]

hey, can you please enable the website you've provided in the description, I am doing this circuit for my school sience fair, which is very important for my grades , the info. on the website would really help me under stand what things I need and the theory behind how it works, CUZ you see I have to submit a report too , so the website would really help me make it. It was available earlier I dont know why I cannot access it anymore, so if you could just look into the problem, it would be great help. also really appreciate the great work you do!👍😊

[@Science.Buddies]

Hello - we're sorry if you had trouble accessing our website, we just checked and the link appears to be working fine. There may have been a temporary problem with our site or your internet connection, but please try again and let us know if the link does not work.

Did it worked ???

[@PreLexander]

If I use a 2xAA battery holder, would it still function?

[@Science.Buddies]

This circuit needs a 3xAA battery holder for 4.5V. A 2xAA battery holder would only supply 3V and that won't be enough to activate the transistor in the circuit.

[@Shaikh999]

​@@Science.BuddiesI want to use 9v battery so is this possible???

[@fardeenbhisti2061]

Which n channel mosfat i can use in instead 6:37 6:38 6:40 6:43

[@Science.Buddies]

Please see the link to our website in the video description for a materials list.

[@matthewericcuyco7583]

Whats the specific type of potentiometer used? Thank you

[@Science.Buddies]

It is a generic 10 kilo-ohm potentiometer. You just need to make sure it has breadboard-compatible pins and not solder tabs.

[@matthewericcuyco7583]

​@@Science.Buddies where can i buu this? Thank you

[@Science.Buddies]

You generally can't buy them in physical stores but they are available on Amazon and from electronics vendors like SparkFun and Adafruit.

[@badhadhakenenisa6830]

I dont see the link and I need this for my science fair 😢😢😢

[@Science.Buddies]

The link is in the video description.

[@xselectroniccircuits6290]

nice

[@Visionairez]

How do you make it ??

[@Science.Buddies]

Please see the link in the video description to written instructions on our website!

[@liveSL6I26]

what is the mosfet name

[@Science.Buddies]

This or something similar will work: www.amazon.com/gp/product/B07CTF1JVD
