How to make a SMART USB FOAM CUTTER with Just 5 mins 

All these comments from these negative naysayers.....you can tell they've never been a kid with the urge to create while not having the means to go out and buy the necessary tools. This is great and an excellent example of limitations increasing creativity. Bravo.

Most useful/convenient walkthrough I've yet seen. Well done and Thanks!

Que buenos alicates!! Lo cortan todo!!

hello, i use wire that you use to hang clothes to dry, the one reinforced with metal wires inside. i use one of the metal strands inside. works perfectly, you don't have to sacrifice your soldering iron. regards

Great project and tutorial. 👍👍👍

Thank you! I made one like this and it works really well!

Very nice explan

anyone else cringe when he used those flush cutters to cut the clothes hanger?

Thanks, work for me. Just i had a broken soldering.

Increíble, 100% espectacular 🤟🏻

Kiddo! you're so smart, I love your brain!

Very good!!!

its so good you have a very good hand

Really very good 🥰👏

Nice. Thanks for sharing.

Your need is nichrome wire, battery, popsicle stick and wire.

Thank you!

Why ruin a perfectly good soldering iron when you can easily use a strand of picture hanging wire.🤷🏻‍♂️

Cool. But where to get heater wire without destroying my soldering iron?

I always new some people were stupid .Now with the help of youtube it,s on screen and everyone knows.

Hi, nice video, I tried this, even bought Nichrome wire, its like the 5V is not enough, I did calculations and I should be able to use a 12 inch length, but its like no power is going through the hot wire. Any tips? I am about to make a 115 v system with a down transformer but my calculations say its not necessary. I haven't soldered connections because I am just testing, is it possible the connections are not good enough without solder??

Very cool

Did you seriously use scotch tape on a wire that’s going to get hot enough to cut foam? 🤦🏻‍♂️

So now you have to buy a new soldering iron

Those are not wire cutters, they are flush cutters and you just ruined them by scoring a coat hanger with them.

What type of metal are the rods the nichrome wire attaches to made of? Do you know its normal aplication? It will make it easier for me to find it in the hardware store if you do. Nice build.

Wow, you didn't have to destroy your soldering iron, you could have just gone to a home supply store and bought wire there. LOL

Great idea easy one I might sound silly would housing fuse wire work the same ? Can someone tell me please and thanks

Nice👌😯

and this one nice too.. like😊

Hola que bvuen trabajo. Puedo conectar los cables cada color a cada lado del micron sin que haga corte

me encanto💯👌

great !!!

This is amasing

What is the wire called pulled from the sodder tool? I'd like to make a 5 inch tool.

Cool!

You’d be crazy to make this. You can buy a hand held hot wire cutter cheaper than a soldering iron. Really unsafe

Why not just buy heater wire... Seems like it would be cheaper than a soldering iron. I guess your trying to show working with what's on hand... But I don't have two soldering irons I don't have even one... I like how you used a USB vs many other videos I've seen that take power cords off random appliances. I feel like that's an item many people have on hand(USB cords)

Brilliant! How long does it take to warm up, and is soldering a must?

The obvious weakspot is where the USB and NiCr wire are connected. I'd rather have a fixed point where the USB lead enters, or a wingnut to keep the NiCr wire in place.

No wonder my mom's hanger keep on missing 😆😆😆

that is clever, have you diagram or sketch in details of wirings.

Can i use guitar wire instead ?

Current nahi Marta kya ye

the structure of al-12v does it work?

What is the awg of the nicrhome wire

very good

Would you please make a video of things that kids could make easily such as the grater

What is that thing he used? The wire that goes on the sticks?

I would NEVER make an unsafe circuitry like this and plug it to a power source (as in AC power). 9V battery "maybe" a safe way to do it. But, I am still dubious about all of this.

Wow...............

can i use a thinner nichrome wire which is also present in the bottom layer of soldering iron?

my voltage is droping to zero.. what am i doing wrong?

is it safe?? i mean if u connect both end of a battery so battery could be explode.

Awsm poroject btw which song diid u use

can I use a cooper wire insted of that wire in the soldering machine?

Hello, could you please tell me the values on your portable charger ? (output and input) I think I am doing something wrong... If I use my portable charger the wire is not even warming, but when I made a new cutter with connection to the outlet then the wire is gone in just fucking flash (literally burned the wire) - Do I have a bad type of wire or am I doing something wrong with Cu wires ? Could you please explain me with more details ?

could I possibly do the sane set up but with the micro usb end instead?

from where you are buying motors,batteries ,etc

Will I be able to cut thicker foam with this cutter ? Lets say 10-15cm thick ?

Which wire is this???

ita normal wire or its some special/high ohm wire?

what kind of wair you use..for cutting head

How giving volts

So you ruin a soder gun to make the cutter?

you can use coper wire instead of nicrom

what the wire you have used in cutting ?

It's nichrome wire not heater wire

Can i use any other wire so i cannot destroy my soldering iron

Please people. There are better and safer ways to do this. Just look elsewhere.

I'll get that cloth hanger from?

do we use with copper wire

What material was the cutting wire?

you dont take the paper off! it only cuts through styrofoam not the paper

i dont understand the "smart" part of this.

Gatel jaran

kann mir wer sagen wie des Lied heißt?

I cant try cut iron bars

ok so i just made this and nothing happened. it didnt even get hot the cord i cut had a green and white wire as well was i supposed to keep them? can somone plz tell me what i did wrong. i didnt have nicrome wire so i used kanthol wire it still does the same thing

It would ruin the charger battery after a few minute's use

You connected at 5 V???

JUST TO BE SAFE, I RATHER USE A POWER BANK THAN CONNECTING IT DIRECTLY TO THE OUTLET.. ITS LESS DANGEROUS IF SOMETHING HAPPEN... OR MORE SO, ILL JUST USE A NINE VOLTS BATTERY AND NOT A POWER BANK.. THAT WIL DO.. RIGHT>?

is it work on 9v battery

i need study with you...

I made the same but it didn't work

Plz anyone just tell how to do the connection

give me music link please

What happens when your hand touches it

A) Wrong tool to cut hangar B) The wire in the soldering iron is not what makes the top hit C) Current will follow through the hangar, which will greatly reduce the efficiency D) A USB cannot apply enough current. This video is a joke.

Don't put this in your computer it will break

I just made this but it didn't work. The wire turned bright yellow and then back to normal after a second and it couldn't cut through the foam :/

it takes more than 5 mins

for those of us without spare soldering irons lying around for us to ruin, what should we use? xD

man, accidentally touch the hanger when it is plugged, electrocution ensures :o

I do better with a box cutter 0 minutes >5 minutes

it dont fucking work

Destroy soldering iron, USB cable, a hard to find heavy gauge wire hanger and never borrow nor lend him, think it's male, unsure from cutout images, never lend anything to him/her... Such waste and how does the whole metal hanger and heating wire work??? They both conduct electricity, one better than the other. Most of those persons incarcerated are much more intelligent than the rest of the humans, just put that intellect to wrong use and got caught, much like this hot wire act. Wink. Hot wire act, hooded while restrained to a wooden chair. Get your mind out of the gutter, it's already standing room only, for this capital punishment, green mile, screw up.

This is super unsafe, and could end up killing you dont do this people. PS it takes longer then 5 minutes to do what is done here. But regardless dont be stupid enough to try this ever. My dad works with stuff like this all the time and its freakign dangerous.

Very cool
