31 people burned their fingers

[Malcurious]

oh Colin and his drawings.

[pkmmama]

He is funny!

[tomakosssss]

0:31 jesus!

[syndrome130013]

thumbs up if u want him to make a diff channel on electronic basics

[damperdon]

i-i-is that a synapse !!!!!?!!!!!!!!

[djay2rapstar]

@damperdon ASK DOPAMINES IF THEY WENT TO INDUCTION MAYBE THEY WERE TOO DRUNK THEY DINT NOE

[m8rox]

Thanks for teaching us this!

[danszimmy07]

I agree with Milohemlock... You have a real gift in just being a genuine, straightforward, ridiculous talent whose sharing of knowledge is nothing less than a privilege for all of us.. Thanks Colin....

[TheSimpsoys]

Easy to understand when your instructor doesn't have a REALLY strong accent

[sadboy467]

i love this person . . . . . great man

[MrJumpersun]

@11vga They' re making all their own music and they don't cell it

[ave383]

Are you an artists?Your using paint markers.

[11vga]

Can some one please tell me the name of the song(beat) at 1:36 sec. Its amazing:)

The video is amazing too:)

Thanks..

[kindpotato]

or a metal picker upper in the garbage thingys

[kindpotato]

or maybe a weird piston engine

[kindpotato]

you forgot about a speaker

[thedataflo]

next time use a sissour take it bakward in your hand put the stin tourgh and put the nail in a scewdriver tada instand inductor XD

[MilanKragujevic]

your hands are shakkkiiiinnnnggg...

[ChiIdKiIIer]

i shit my pants when he open the box at 0:33

[ChiIdKiIIer]

you mean that the inductor can be used as a capacitor?

[antonyguit]

i want oyu to be my teacher at the subject electrically...my school in Greece sucks..!!!

[belshazer]

u are awesome!!

[xnp70]

I don't understand why he draws the current backwards !!!

electrons travel from - to +, electrons are negative, and are attracted to the force that attracts them which is voltage

[VelvetSynclaire]

@xnp70 stop being an asshole you dick

[TheBoringProphet]

@xnp70 It's just convention, man.

[xnp70]

@TheBoringProphet hm... ok, got it, I still think it should be the right way...

[myguitardidyermom12]

@xnp70 conventional flow

[MrChosenone34]

@xnp70 I was wondering the same thing

[MrChosenone34]

@xnp70 About all of this, I don't understand why they draw schematics in the conventional flow manner. Does the serial order of the loads not matter? Does it not matter if you put a resister "in front" of something or "behind" it?

[valentass88]

i dont like the bar that pops when you press like

[chilidress]

i want a 60-150uH inductor operating at 15Amps how can i make one ? i cant find it in the market...

[bhayful]

Amazing....i Was searching for the electronics tutor and guess what i got the best tutor!! thanks..Oh lord give me strength to learn physics..plz plz

[TheBlacksabbathfan9]

I got thrown out of my schools science fair cause I made an electromagnet that got so you it melted the plastic table!

[LittleJohnEnterprise]

ahahha 4:27

[TheColdrevenge]

school would be better if people like this guy were teachers, because we could actually understand what were learning, and not have to worry about the next test.

[cthatshit]

thx for the explanation, it was clear and easy to understand! its amazing how much more i learn from youtube than lectures

[TheHassanhass]

i am true fan of you SIR.............

[alsports2000]

I 100% agree with Milo who commented on how some persons can teach but cannot explain it in a way that one learns from it, you do teach and explain it very well. I just finished building an electromagnet using a D battery and a screw wrapped by an insulated wire. One huge problem: as soon as I connect the negative wire the wire gets very hot and starts to smoke and I burn my fingers. Question: Is there a way around the heating and burning aspect to this project??. Thanks. AL.

[jaspr1999]

@alsports2000 I may not be as eloquent as the video might I suggest taping the wire to a block of wood or glass and reduce the amount of contact with the battery to just a few seconds. This way you don't run the risk of burnt fingers or other issues.

Hope this helps.

[Insignia96]

@alsports2000 No :D since an inductor is also a resistor, it heats up! more turns will reduce the heat though!

[MasterThief1324]

What's the purpose of the enamel on wire? To keep the wire from attracting dust so that it'd be more conductive?

[emmaskater]

i wanna make a pedal just like that one :D

[dreamsean]

Good day Sir, how do i determine the given amps out put of my project inductor or transformer and also the volt current? pls help me as a student!!! 100 thanks!

[KoreanMeatball]

You make it seem so simple.

[ebird97]

Electronics for Dummies + MakeMagazine = Knowledge.

Knowledge = Power.(literally)

[kailash317]

hey can you please make a tutorial about a telegraph pleaseee

[MrEinstain]

Now i wanna make a guitar pedal with it. Perfect. D:

[lukebaldan]

30 people who disliked failed to achieve magnetisation

[xsni]

More!

[lucasmontec]

More!

[prence1725]

 makemagazine@ can you please help me find the formula of 0.1uh Henry? i dont know the amount of turn or any thing. only if i know the formula

[TechBoywii]

ANGREH TRANSFORMAH

[twigga91]

this video is so useful, thank you so much you really make things easy to understand i wish you were my lecturer.

[XxiOWNlySNIPEx]

This guy is growing on me

[vincentmagician]

soooooooo, if a magnetic feild passes through the coil it creates electricity as well hence how manual charge devices (like the shake to charge flashlights) work right?

[TechBoywii]

@vincentmagician yes :P

[jbubs150]

CAN YOU PLEASE SHOW US HOW TO MAKE MUSIC WITH INDUCTORS? please?

[keithosmarferrer]

1 boring class= 1 hour

1 very cool and very informative video= 10 minutes and 46 seconds!!!

[mindstormsabrewin]

@keithosmarferrer I think most schools in America should be shut down immediately. Put that money toward free computers for every kid. Why spend months trying to learn some concept from teachers that barely know the material themselves? Schools are savage insane asylums for thugs. They don't want to be there. So why should students that WANT to learn be victimized? Let kids find their own answers and then take the tests at the end of the year. No need for classrooms anymore.

[keithosmarferrer]

@mindstormsabrewin yup yer wright!!!!

[trapingman]

lol dark blue... not good enough!

[asirianinagony]

more Colin!

[EPICT0ASTER]

science roolz

[typedeaf]

Good lesson. I am curious about how the signals are represented as normal (square) and with an inductror (sawtooth). How could you apply this to modify audio signals. Your box of pots appears to be doing just that. Do you explain how to make a gadget like your box to modify sound waves? I think that would be awesome.

[allegrobas]

Excellent!!!

[TheSuperLaxative]

he is like my 10th grade electronics teacher but better

[MrStemkilla]

your hands are really shaky but your vids are grate

[milohemlock]

I wanted to thank you for this explanation. The world is full of people who

can explain things. Few do it well. You actually made the concept understandable as well as entertaining. If I had you for an electronics instructor, I wouldn't be such a loser today... Well, I'd probably still be a loser, but I'd

be a really smart loser.

Thank you, and keep up the excellent work.

[youaresosolame]

@milohemlock SHUT THE FUCK UP LOSEEEEEEEEEEEEEEEER GET THE FUCK OUT

[rockerzac99]

the sketch of the transformer should be in the MOMA

[testyalien08]

So you can wirelessly transfer electricity! COOL!!!!!!

[gonepishing]

so incredibly understandable!

[Frank12387]

Cool 3D title and credits!! (Need 3D glasses though...)

[schnappy00]

I've learnt about magnetic field lines, is that the same thing as the EMField? I was not aware that it had a charging-up property, I always thought the current just induced a magnetic field.

[dealio82]

What is that high pitch sound in 7:00 min

[schnappy00]

@dealio82 He increased the frequency of the wave generator, which also produces some sound... high frequency high pitch.

[boxa888]

@dealio82 frequency devices, simple as a transistor oscillator or a 555 chip, very easy electronics, then its causing sound in the oscilloscope, ive done it tons of times, its like leakage in the circuit causing sound, a nearby spreaker can sometimes pick it up too.

[prosper58]

i like how wearing 3d glasses actually makes the title/credits in this video look 3d.

[Piperrako]

yeah i want one too !!!

[karajazemeyeh]

thanks

[myguitardidyermom12]

00:29 Let this be a lesson kids; never use the same color wires for more than a few connections.

[ThePKSnipes]

"What's up Henry"

[daviddanielgraham]

@ 6:08 "The upside is Kirby"

[hazemgoal]

that is a perfect explaination

go on with the other physics man ! you are very good teacher

[MrROTD]

Pink Floyd!!!!

[mindsoulbody]

IT only looks and sounds good as long as it is kept to the basic definition. Once you start working on RLC circuits, both Capacitors (C) and Inductors (L) are pain in the ass.

[wbootle]

magnitazation

[bargald]

the titles in the begining are 3d XD

[RavenRof]

you are my electronics teacher. cause thats the best way to learn electronics.

[unix001]

a collapsing magnetic field induces a current in the opposite direction of the power supply

[Mr60ftlesbianoctopus]

I like the tunes (:

[madaboutpix]

keep the videos coming, great work.

[cacneaunit6]

plz help, i dont know how to use a multimeter and i cant understand the instructions, HELP I NEED HELP IF CANT UNDERSTAND A CApacitor AND A MULTIMERER I CANT MAKE MY COILGUN HEEEEEEEEEEELLLPP!

[SockPupp]

@cacneaunit6 your screwed, just give up

[cacneaunit6]

@SockPupp NEVER, DICK!

[bombthesystemsnl]

great!you make me smile!hahaha this is awesome!love your vids!

[akmikeman35]

so this transformer takes in electricty then reduces to another size?

[vevasam]

@akmikeman35 yes. the voltage levels can be reduced/increased by properly choosing the winding turns ratio from primary to secondary.

[thomaskaufi]

the thing after the motor, did he say "salonoids", kind of a piston i think, what is the correct name, i reaallly need one, but i dont know how to spell it.....

[rawrsaidthemouse]

@thomaskaufi The word you are looking for, is "Solenoid" which is basically an electrically controlled "piston" type device.

[christianernord]

wat ting are you using in the begining ? and how to make it ?

[bratmassakern]

i have an electronics test tomorrow, man i wish i had you as my teacher ^^

[andrewrobotbuilder]

Wow Colin, your explanaition of electronics is not only more detailed than my physics lessons, but also more fun!

[sephiroth671]

@TheExistingFilms

lol

[51235465789]

Need more videos from this guy

[mindsoulbody]

He looks like one of those 18th/19th century scientist who got revived to give us a lesson on electronics. And while at it, he rocks and looks like Isaac Asimov.

[TamaN47]

what ever you do dont put 2 wires into the two holes of a ps2 c adaptor really hurts got a blistur

[tomek123kotek]

this just makes it look like a capacitor or wait

[altostratus5]

great vid!

[sephiroth671]

you cunt

[gythaporas]

Interesting, down to Earth and accessible. Thanks.

[fragglesparky]

great videos,very good for apprentice electricians to help them see all of this in a clear concise demo

[puddle331]

I know where angry transformer is he is duplicated him self he is in my X BOX 360 and my PS3 I hait angry transformers

i hait angry tranformers

[gmartin5131]

8:41 to 8:46 he is holding a different pen. horrible editing come on..... =D

[5Spekter]

28 people livin in kentucky

[ranger8792]

Excellent

[AxelTiger]

Shoop da woop transformer!

[dodgedart74]

i hope this guy keeps making videos even if they fire him from make magizine.

[devinmccloud]

All I can say is, I love the hidden humor, history and simple explanations. Best learning experience yet. keep up the great videos.

[ElectroCompuGeek]

I like the inductor. Its what makes intelligent relays (also called Allen Bradley Pico Controllers) possible as well as many, many other electronics possible. Intelligent relays are used to control factory equipment and even giant robotic arms. Very cool!

[desfire13]

soo you can make something like a resistor?

[SpeakingSerpent]

Teachers or anybody here to really learn, i just wanted to bring attention to this line.. 8:55

Through mutual induction "The original voltage can be reduced by using a different number of coil windings"

There are visually entertaining experiments that can be done to get kids attention using this principle/fact.

[94vujke]

thanks dude keep up the good work !

[juliolux]

I am of brazil and the like to the congratulations for video.

[peterpants7]

Cool video and a interesting presentation! I like this series, your style reminds me of carl sagan.

[picaticatara]

Trippy assed font.

[faturd95]

Worst 10 minutes of my life

[Jallandhara]

@faturd95 Nice to know you invested all ten minutes coming to that conclusion, champ. You could have closed it and gone back to watching your pseudo-intellectual Shane Dawson videos at any time.

[wilfeatscheese]

well good music mate

[FPSGameHackers]

Hey could you make a video on a zener diode please?

[Moneim23GK]

i need to build a square wave generator like the one in this video !!

[jamieagerholm]

the danish scientist Hans Christien Ørsted actually discovered the powers of electromegnetic powers. But is always forgotten! maybe because he did'nt explaint it closer

[grendelee]

wow. More then meets the eye...

[garylewis91]

awesome informative video - way more fun than sitting in one of my old electronics lessons

[tikay69]

WRONG at 9:05 , "the original voltage can be reduced by using a different number of coil windings in the secondary", should have added "or increasing the coil windings in the primary". If you wanna be exact you gotta say both :P

[VictoriaFalls12]

These vids really are brilliant - I like this guys sense of humour too :)

[jaesungauzakim]

This guy is just... Simply Awesome

[gnrfanatic141414]

could you show how the inductor works in an audio application?

[grendelee]

@gnrfanatic141414 thats pretty much what you saw in the waveform thing. Just pretend thats a sound, lol

[vik95170]

the vid' is great, the music to !!

[user12119]

Can using thin wire for the secondary coil effect the voltage output of the secondary?

[iloveflyingac]

hey, thanks for this cool video. this is what i was really looking for past some days.... but i want to know how to make a step up transformer.. i am looking for converting 1.5 V direct current to like 200v is it possible with step up transformer........ please reply please thanks...

[thewii552]

@iloveflyingac well, it MIGHT be possible with AC, as you can't step up DC. I am really not sure, though, if 1.5v is enough to get to 200...

[JagdtygerII]

@thewii552 not a problem, but you cannot get anything for free, any increase in voltage has a coresponding decrease in current by the same ratio, thats all.

[tikay69]

@JagdtygerII the current doesnt get decreased in increasing voltage, the max current output stays the same at 200volt as it would have been at 1.5volt, so thinking he ment a battery, it wouldnt be "much".

[JagdtygerII]

@tikay69 Sorry but what you are claiming would violate the laws of Physics. Power, or in the case of electronics Watts is voltage times current (I x E) and if the maximum wattage or power draw from a battery is, say 10 watts and the voltage is 10 volts wattage must be 1 amp. If you boost the power to 100 volts and current stays at 1 amp you have 100 watts. Not possible.

[JagdtygerII]

sorry I meant amperage must be 1 amp. Typo

[KaiNogard]

[marcuelcajon]

These Videos are great. Collin could have his own show. I would watch it. Also I think Collin could play a Interesting Agent Smith. The way he pause's when talking. "Mr Anderson"-------

[mike1829y2]

nice video and Collin were you in Apollo 13 because you look like one of the guys at mission control.

[Serpico261]

@mike1829y2

i think u mean SM/CMC controller

sy liebergot, played buy this guy...ron howards brother

[memoduran]

Great vid! thanks for taking your time explaining these kind of stuff.

[AMooneyPilot]

From an EE guy here..Great videos!..keep em coming!

There exists enormous ambiguity in some of these topics (like which way does electrical current flow) and both right answers require a fair amount of additional information that will bore your entry level audience as you probably know.....

If any comments get nasty, delete em!

Maybe your vids will inspire someone to go get more training, or maybe even a education as an electrical engineer!

regards js,

subscriber & maker fair attendee

[DeadBodyOutline]

I'm still grasping the concept of it. Would this be the same type of concept a turbine say a wind turbine or any other kind of turbine would be used to conduct electricity? through magnets revolving around copper?

[CotiBoy]

Try watching from 1:30 to 1:48 with 3D glasses :D

[myztic123]

didnt work

[Vectorr4Emperor]

Angry Transformer is... ANGRY~

[Mr60ftlesbianoctopus]

@Vectorr4Emperor

Anon ;D

[BambooSamurai33]

Dude, awesome video... I didn't know it was that simple and yet so effective and useful!

[MrZeus7]

What inductor did he use? I forget what the measurement is called, the one in Henrys. I'm trying to recreate it on multisim but I'm not getting any luck.

[carlosnba]

wow this is useful

i'm studying this now and now i get it

thanks!

[XANDERXXZ]

wo wo wo wo, electrisity runs from negative to possetive, and that isnt the symbol for a battery or cell either.

[chaseantarctica]

lol seriously? its not meant to be a technical diagram, its drawn so that anyone can understand it.

[XANDERXXZ]

you might be right on the cell bit, but the bit about electrisity is just a lie, even if it was to make it simple he could spend a couple of seconds explaning it.

[Harpmaster9000]

@ XANDERXXZ

People like you are the reason the comment option sucks. You take a simple video that is meant to give someone a good idea of what an inductor is and try to act smart by pointing out flaws. You cant even spell electricity or positive. Yes, electrons move from - to + but in any circuits course the current is labeled the opposite way. And since you are so keen on the fine points, it would be spelled whoa not wo.

[XANDERXXZ]

First of all im dyslexic so think before you attack me for my spelling. secondly the fact that you are so affended by my casual comment that the INFORMATIONAL video is wrong shows what a sad piece of shit you are. Its not like i was saying the vid was bad, i was just correcting somthing wrong in it, that can give the wrong ideas. so when you reply to a comment dont spend your time talking shit and trying to find misstakes in the most boaring things like spelling that i dont give a shit about.

[Harpmaster9000]

I'm not saying you are bad either, just correcting something wrong I saw, like you.

[mathman47]

He shows "conventional" current, the flow of electrons from + to -.  Current actually flows from - to +. Unfortunately, good old Ben Franklin got the flow incorrect and we are stuck with it today. And please use a spell checker!
