MAKE presents: The Capacitor

[kdc43]

Thumbs up if you think he looks like a young Isaac Asimov.

[BMSreligion]

you sir, are awesome

[tickyul]

Wow, great video....really interesting.

[Mechaman365]

now this is some fucking explanation !!!

[pkmmama]

@TheSuperTecnology,thank you.

[IJahILuv]

thanks for this guy. helps for visual learners thats for sure

[bltinthehood]

if you cut your hair i would fuck the shit out of you call me :) <3

[pkmmama]

How many uF are there in a super cap.? Thanks.

[TheSupertecnology]

@pkmmama super capacitors store farads, and can handle and store lots of electricity, careful whit theme when charging

[Oshiba88]

Can someone tell me if it’s possible to use an alternative to a 2.2µ 15V?

I can find some capacitors with 2.2µf but they all have a different volts...what does the volt mean btw? Is it how much volt it can hold or how volt it can handle before getting damaged?

I’m playing with a DIY instruction and some parts are hard to find.

A 10K resistor is connected to the 2.2µf 15V cap- is it possible to change the resistor value so that I can use another cap?

Need help please!!!

[DrEMplushrest]

@Oshiba88 The voltage is the maximum the capacitor can handle without damage. As such, you could use a 2.2uF cap rated for 16V, 25V, 35V or even higher, provided it will physically fit.

[buho62]

I have a slight feeling that this guy has been electrocuted a few times. Videos are awesome, but he's freaking weird!!

[SomepartOfNight]

You look good and so smart.

[tatkonerez]

Doc and McFly have a lot of rubbing to do.

[OverLordSky]

Why did the green ground wire connect to the PVC pipe that he was rubbing the yellow wire with?

[chaz1488]

Just don't get the poles of your capacitor mixed up when your installing it into your project.

[TheENGlion]

ok sir--thank u for this present--but i dont Understand circuit of the capacitor discharge??can u paint it to me???thanks

[freethisone]

you been a great help.

[crapintaholeintawall]

Hey thanks a lot! really helpful.. Oh and hey, is it possible to use an alternate source of charge, instead of connecting it to the ground?

[TheFabioEiji]

0:57 LOL AT OSCILOSCOPE

[perazaroberto2]

GOOD JOB



[trannguyenbaotrung22]

Please help me solve this problem: Why does 22 pF ceramic capacitors can't be charged like a 10uF 16V Electrolytic Capacitor?

[HoracioFdez]

Collin you're my hero! :D

[ChrisVGuitarist]

36 people don't have badass sideburns

[kindpotato]

also does a capicitor let go of its charge once it has reached a specific charge like it did in his second example

[kindpotato]

why cant i view this video from makemagazines channel

[dimplez293]

Explain how to charge it. I followed all of the directions and it still doesnt work

[Panicatthebusstop]

What's "ground"?

[alanponte]

@Panicatthebusstop 0 volt, Ground Node.

[HexaDecimallify]

@Panicatthebusstop thats GND or -

[technologyguy223]

@Panicatthebusstop - negative or 0 volts

[Tranqspogi]

amazing! 

[davidjjdj]

can be verry large i was like OMG thats huge! your the best dude!

[RobinPooley]

I really enjoy your work. Thank you.

[chilidress]

@makemagazine i have a 200v 3600uF cap bank and i want to fully charge it with a 190v power supply how many amp the supply should be to charge the cap bank in 1second,and should i use any resistor ? answer asap

[nialls9]

im doing this at school :D

[drummerjoeycastillo]

get your own channel please

[otamanlvhs]

Awesome background music and awesome tutorial

[javisan14]

I have read and seen many video and they weren't able to translate or explain, things like you do; please don't stop making videos.

[perkerfrans]

you missed out what they are used for, beside storing electrctrons. Why is that needed in electric equipment?

[DoItYourselfMaker]

why is your hand very long



[Schoening91]

awesome :D

[SirDude456]

your basically separating a negative charge from a positive charge to make potential energy and than releasing that potential energy whenever you feel like it, this process is MUCH quicker than a battery that stores a chemical charge. cap.s are now being researched to make ultracapacitors that can store the same amount of energy as a battery, but they would be able to release that energy in seconds which would be awesome for soo many things, we wouldn't even need battery's anymore.

[TheBlacksabbathfan9]

I'm craving TACOS!!!!!

[dealio82]

CAN I INCREASE THE SIZE OF MY LADDEN JAR TO GET A BIGGER SPARK

[lubeenz]

ur theme music is DOPE!

[cschooley]

@45muncher Then go watch Charlie Bit Me, okay.

[nafativedec]

will capacitor stop conducting when its full?

[TheColdrevenge]

the problems with microcontrollers, like the arduino, is that you dont get to use these things cuz they do everything for you

[manolitomulat]

the tower of power electrolytic capacitor

[manolitomulat]

danger!!! genius at work!!!

[ziyadguliyev]

Thank you man. i love you. Great work. Very good.

[Peedlebum]

A very interesting and informative video - got to watch all the others now! Thanks for posting.

[persevere67]

a great demonstration of intelligence, thanks man

[TheHassanhass]

oooh very good, now i can make a capactor

[dos541]

what was the song that was played off the cassite in the begging

[mrmadmanknows1]

how much charge can the film canister capacitor hold?

[rfengr]

hey MakeMagazine, why did you skip the memristor ?

[cristian3131]

more Make please :D

[ToiletStruggle]

can you be my high school teacher?

[RATMAN775]

@ToiletStruggle nice user name.

[swedensy]

@ToiletStruggle

This guy is not talking that way to be your high school teacher.

/bored

[kdc43]

@ToiletStruggle ............What kind of screwy name is 'toilet struggle'?  Constipated are you?

[unreasonablebannana]

another question... i have a capacitor from a camera (200 mfd, 330 wv) and i can charge it but it only shocks me as much as i charged it, example if i charge it with a 9 volt i only feel 9 volts if i put it to my tongue... am i missing something that increases the volts?

[Escaladist]

@unreasonablebannana the capacitor will only hold as much voltage as the battery has, so if you're charging a capacitor with a 9V battery, it will charge with the electric potential difference between either side as only 9V. The 330 V written on your capacitor indicates the maximum amount of voltage your capacitor can take before it gets damaged. So, if you amplify the voltage of your battery (using an op amp) to around 300 V and then charge your capacitor, it can be extremely dangerous.

[rolfarj]

@Escaladist Thats NOT how you use an opamp

[mathscirocks]

i built a leyden jar that was bigger and it made sparks about 1.5 inches at the best and it was very painful to get shocked by it. i could only charge it using static electricity and charging it with a battery would result in absolutely nothing. does anyone know why?

[unreasonablebannana]

very informative, but why does a 9v battery not shock me as a capacitor charged with a 9v battery would?

[NPGRocker]

I've also used wire from a headset, is this good enough for conducting? ps: there's this even more ittle wire inside the wire of the headset, might this et something fail ?

[NPGRocker]

is it necessary to let the conductor go to the ground ?

[prence1725]

@makemagazine can you please make a video on how to make inductance? example, calculation. henry mili enry etc

[lucasmontec]

MORE

[pigwigpa]

I remember building 100 kv cap. Try discharging one of those after testing. KA BOOM

[Miguelyou2]

i like the way you teach man nice work. I would like my electronics teacher teach me that way.

[ConnorXV]

can anyone tell me how i can find the instantaneous current from a 330v capacitor with a capacitance of 120uF? The circuit resistance is lets say 1 Ohm (or less) and i dont know the time constant (how do i find it also?)

[ConnorXV]

@ConnorXV oh and what is it likely to be?

[Digitalman271]

Im confused about how you connected it to the ground?

[RMASHWAN]

9805127308

[AKSoapy29]

How do you make your music?

[TheWaddleWaddle]

@AKSoapy29 He stares at his instruments/computer untill his sheer awesomeness forces them to make badass music

[AKSoapy29]

@TheWaddleWaddle I'm pretty sure he counts to 69 and throws baseballs at walls first.

[skywalk3r15]

I love this guy, he explain very well and even beginners shall easily understand the explanation. Nice One Again!

[tiger12220]

I have a question, what is ground used for in his home made capacitor? I am sorta confused, would some one please be kind enough to explain the basics of what is happening in his set up besides the actuall capacitor. Thanks 8D

[ConnorXV]

watch ' how to make a 400v charging circuit ' to learn how to make a circuit from scratch capable of charging photo flash capacitors, you need little electronics knowledge and you only need four components.

[XftumchX]

I cannot stop looking at the oscilloscope in the background.

[yesschembri]

@XftumchX i dream of having one :)

[excriminal1]

you should have been my school teacher.. i would have learned more :P

[PmOrComment]

What was the third strip of aluminum for, you said three strips.

[GingleGangle1]

Hey, do capacitors contain rare elements?

[XBENSTARX]

@GingleGangle1 He just showed you in the video.

[GingleGangle1]

@XBENSTARX Really? What kind? I didn't see.(

[ox141jf]

not he didn't mention one of the BIGGEST use of capacitors!

RAM or Flash memory , your memory stick, computer RAM even calculator memory , all the mot valuable and most common use of capacitors.

Now you may say "they aren't really capacitors because they arent used to store large amount of electricity" however capacitor definition "something that stores an electrical charge" is exactly that for Flash memory except it stores a TINY! amount to symbolize on or off , 1 or 0

[yousini]

how come you need a resistor with that lightbulb(led?) experiment at the end? could you do it without it?

[Master0fDeasater]

@yousini There are still 9 Volts in the capacitor, so at the beginning when the cap ist full of energy you have to use a resistor beacause the LED just needs about 3 volts otherwise it would kill the led.

If the Cap is not full of charge, the LED could run without a resistor.

Hope my english is good, because i'm from germany :D

[TheWaddleWaddle]

WARNING THAT SPARK IS LITERALLY A "BLINK AND YOU'LL MISS IT"! I HAD MY OWN EXPERIENCE!

[jtgober87]

youre the best teacher ever. i wish u could have been my high school teacher

[aljemax]

VERY useful!!! thanks for posting this.. ^_____^

[ShootAllQueers]

how do you make a capacitor spark every second or so?

[Ludzee1337]

34 people did not understand

[acerjojo12]

wow that was awesome dude make more vids like that i have never seen a vid like that on youtube.com

[acerjojo12]

wow that was awesome dude make more vids like that i havenever seen a vid like that on youtube.com

[TeddyBear1111998]

How many volts does that Spark make?!

[blurble99]

Awesome! Great explanation, simplified, fun, relevant. My 6 year old is so excited to find your videos!! Thanks!

[lillianhansen153]

I tried....I ended up failing...

[lillianhansen153]

I swear....it's impossible! Haha! :D

[lillianhansen153]

Love it! I am doing this for my science fair project..it is due tomorrow and I still havn't done the experiment, I am confused by the way you explain it. :(

[abelcool23]

does not work your campacitor jar ....but briliant info

[halflife9764]

lol nvm just got it to work!!!!!! YAY :D

[halflife9764]

i tried the laden jar experiment and it sadly failed ;'(

[snrose2002]

loved it .. cheers :)

[lillianhansen153]

@snrose2002 Doesn't help me much..:( glad it helped you tho!

[Psqwall]

What happened to Collins Mac ? It looks like the side of it blew up

[mariasequira]

You are the one of the best practical teacher...

[GREENG0037]

i tried this and failed. i ended up throwing it out the window

[laserman55901]

@GREENG0037 Did you use static as a source? I used a rubber balloon and fleece

[NewtKnight]

Awesome: please continue doing these vids'

[iggy151]

Beavis Audio Research: "Heh-heh...he said butt connector...heh-heh...BUTT!"

[shmexy030]

what Way

[PhuckHue2]

ceramic caps suck butt

[Conde61]

I must admit .. you are the best ,, you explain things the way it should .. thanks for taking your time to do it keep doing it ..  God Bless

[shotgunndunn]

Tone Loc baby!!! Funky Cold Medina!!!

[0000Peacemaker]

love make magazine and the host....,.,.,.,.,.,..best hoice

[darthme1000]

what about the tantalum caps

[Brunoctm]

whats the soundtrack that plays in 3:52???

[vishnukn]

Excellent video and explanation



[townshend445]

your oscilloscope was very distracting.

[FrancekPirosrancek]

just remember it takes about 1000V for mm jump...

[bowlingfor1]

A capacitor is most commonly used to avoid damage to other component in case of open circuit...for example if the electricity cuts off while you are using your desktop computer (assuming it has no other external battery supply) it avoids damages to important chips by gradually releasing it's energy stored, and not letting the current to suddently drop to 0.

[ESCASEPI]

Brilliant explanation! very informative

[renekenshin6573]

Very informative thanks for this cool video :)

[ubuntupokemoninc]

that music is epic!

[Razel094]

this was a brilliant explanation of the capacitor.i'm a bsc in computer science and feel handicapped for not knowing anythin on electronics but this is helping!!

[qwerty1234me]

capacitor is probaly short fr decapicitor

[halo2party]

That little wavy green thing is fascinating.

[dime363]

is the battery a capacitor too?

[renekenshin6573]

@dime363 the rechargeable batteries act almost the same as the capacitor but the purpose of a capacitor is mainly for filtering and batteries don't

[Menimitz]

I am an ECET major, and this video series is the best one I have found for these topics. It makes them very simple and easy to understand. Now I can easily teach these concepts to others and even refresh my own respect for them easily.

Thanks.

[owenchungsweekit]

thank you

[Mr60ftlesbianoctopus]

Aluminium foil.. there is an i in the middle of this word

[callmeshane303]

@Mr60ftlesbianoctopus - no there is gnott.

It's Aluminum, just like Uranium, and Platinium

[Mr60ftlesbianoctopus]

@callmeshane303

Uranium- i between n and u, just like the word Aluminium

[usquanigo]

@Mr60ftlesbianoctopus Only in England. The original term is Aluminum, but it was later changed to match other elements, however, we Americans stuck with the original (closer to the source is more accurate ;) ).

[jamesguit]

sparkplug!



[vevasam]

awesome background musik to start with....

[orbiter8]

I'm just waiting for him to say 'Mr... Anderson' :)

[stoneynine]

So what would happen if I made the space between it like 4 inches and just kept building up static electricity?

[Cokecanninja]

How did you get the pattern on the o-scope in the background? Nice video, keep making them.

[BassPounderX]

I wish there was more video's :( i like wacthing these to ba iv wacthed them all

[Zanith50]

aint there arsenic in capacitors? hope you washed your hands after touching them

[MASTERCON12]

oh, Garage Band samples, you make background music tick.

[Prayimario]

cool, lightning

[settamit]

Nice video, however you forgot to hook your makeshift capacitor to a multimeter and measure its capacity.

[yaya1yuyu2]

Love it!

[mapukmapuk]

is it AC voltage? lol

[Ciaran55]

good videos, thanks!!

[justmarinus]

the people who made pyramids also had a kint of thing like that bottle

[pikachuthesquirtle]

well u can also use a rechargeable battery. :P

[natester632]

So it's practically a crappy rechargeable battery lol

[theraywilsonshow]

This is an awesome video and your presentation was totally clear and understandable. Thanks for posting it. Cheers.

[johnfranks]

Do you write your own soundtracks? That synth @ 3:53 rocks! Hard! Reminds me of ESQ1. I dig the edit @ 7:17.

How many μF was your capacitor? Good work!

-sj

[freakin1random]

how can you charge it with a battery?

[maitilupas]

ALRIGHTY!, now i know with who you look like , BENJAMIN FRANKLIN!! =))

[739199]

Where do you obtain your electronic components? I'm in a small town of 3000 and I can not find local supliers nor online supliers. Thanks for the help

[Nanovirus5995]

@739199 Well, what you could do is go around some houses and ask if anybody has any broken or unwanted things so you can scavenge parts from them. Look for things like, Tape players, T.V's, Fridges, Pc's, speaker. Anything really ^)^ You will be surprised what things some people have lying around their house unwanted. I went to a local scrapyard the other day and got a microwave!

Some of the things in there are pretty dangerous though (Especially the 2100V Capacitor!). So be careful please.

[739199]

@Nanovirus5995 thx

[1omagaman]

@739199 Radio Shack on line for one.

[739199]

@1omagaman thx

[sanjubluerock3]

very nice

[lol9392]

if capacitor did'n exists, i would not be typing this comment.

[ElectroCompuGeek]

Let me blow your mind again. Capacitors are as big as classrooms sometimes.
