MAKE presents: The Transistor

[TheCheesyProductions]

50 people used pnp instead of npn

[ButtsexV2]

god damn man tune your guitar

[drbrain735]

50 people are Amish

[macbookfan33]

no im not using transistors, currently on a 80 year old computer with vacuum tubes!

Dang, another one blew, brb..

[MrROTD]

@macbookfan33 Don't complain , I'm on a mechanical computer, it takes me 5 days to respond to comments.

[jutsmyface]

I am very happy to see the vidoe from you, hopefully the others also are happy for You They electronically switch and amplify signals by harnessing the unique abilities of semiconductor materials.

[indiage]

I Love The Video It Can Increase My Knowledge MAKE presents: The Transistor

[fitnesus]

[pemburuiklan]

Your Video Is Very Useful Sharing They electronically switch and amplify signals by harnessing the unique abilities of semiconductor materials

[drummerjoeycastillo]

EBC = Eat Big Cock

[sanity599]

@drummerjoeycastillo Somehow I knew some low life would come up with that. And just couldn't keep it to himself but just had to share it with the world.

[drummerjoeycastillo]

@sanity599 man, you don't have to be serious the whole time, you can crack a joke sometimes, life is short.

[wrathgar11]

Weren't you in the matrix?

[ataraxic89]

@wrathgar11 he remind you of agent smith too?



[igrewold]

@wrathgar11 haha

u r so funny. he kinda looks like that Agent Smith.

[Malcurious]

I'm learning....but it's entertaining.

[DanialDawson]

This guy must take lots of drugs

[TheMyarse]

badass tie.

[Chippydip]

dude you look baked. great info

[kibukamusoke]

Thanks. Gr8 info.

[jmoreno718]

It's Agent Smith!!!

[cribcat1]

please google the foxhole radio and figure what crystals and transistors are about. This is a great primer.

[AJ8494030615]

or even a...big cookie?

[RATMAN775]

can i get a thumbs up for no reason?

[neveranythingtodoXD]

@RATMAN775 No :p

[RATMAN775]

@neveranythingtodoXD fine. i see how it is.

[htfkid2000]

Eat big cookie... or something similar... I lol'd!

[Yousg27]

Very nice video.

Thanks

[calvert991]

lets unite us nerds

[IslamEmpire]

@STREETRAT211 No it is not a voltage regulator it is a tip120 power transistor

[RavenRof]

What about a Rotary Encoder video? ;) would be awesome. You always explain hard stuff in a simple way.

[syndrome130013]

00:58-01:08 makes geeks look like bawwwsss XD

[WiredLaggKing]

8:02, isn't that resistor on the far right a 7k omh resistor? i didn't see that in the schematic

[Waddeell40]

transistors and tesla coils dont make good friends. just sayin'

[tradecycles]

I CHECKED RESISTANCE OF MY PENIS AND THE LED BLEW UP!

[csguy1980]

Watched about 6 vids already by you and Im hooked. Keep it up!

[ThedudeVip3r1990]

You're the best dude!

[jgrecoarroyo]

I love transistors and cookies too!

[Paggee]

Why do we need the 100K resistor?

[H1TM4NB00THY]

@Paggee Because you need to resist some of the current, otherwise it would be too high across the Emitter-Base junction. and therefore blow open the transistor

[MrGunnaras]

where were you when i was studying electrical enginering?

[Quasi84]

How do you know when you need resistors and how large they need to be? Is it based on the battery input?

[orangesunshine]

looks like hugo weaving's scientist brother

[crackmaster88]

Thank you dude ;)

[kchiem]

Eat Big Cookie.. or something else.. hmm..

[randomcrazyness]

is this guy trying to go for the isaac asimov look?

[kindpotato]

where is your hair

[Tranqspogi]

in my own way, you can use Led connected with 390 ohms and connected to probe 1 to 9v battery as positive and otherwise is negative... same theory but different tolerance

[styxfreak]

rock star teacher? oh ya.

[thedataflo]

very cool video thx but can u reduce the base a bitt i already disconected the subwoofer but it dosnt help and dont bee so loud joung man XD thx and check my channell u gonna like the vaforite collection :)

[jayiscool723]

what about PNP??

[MrStemkilla]

why a resister between the base and the ground? wouldn't that just wast current?

[pinochska]

@MrStemkilla no man.. the resistor limits the current going to the base so that you can control the transistors flow... it can be a safety measure for your transistor or a means to control it.. hope i helped

[MrStemkilla]

@pinochska i think you miss understood. the resister i was talking about went from ground to gate and i think was 220k i believe and too high of a resistance for what your thinking.i found out it is to make shore radio signals do not turn on the transistor so its like a filter a way

[RealationGames]

I'd rather memorize the EBC like ABC, instead of words to complicate it.

[yum499]

PLAY FREEBIRD!

[CoolDudeClem]

So THAT explains how NPN and PNP transistors got their circuit symbols.

[TheBlacksabbathfan9]

Is this a way to think about it? Using a small remote to control a servo motor to control a car. So basically using a small rc signal and makeing it control a car

[un7ucky]

get your own channel plz

[emerybryant]

@un7ucky he has a channel

[perplexedmoth]

@emerybryant and what is its name?

[emerybryant]

@perplexedmoth colinmel (um im subbed to it but im to lazy to look it up so that should be correct spelling tho)

[legoclockfreak710]

44 ppl didnt have big cookies!

[DactaDork]

how would that circuit be effected if a pnp transistor instead?

[MrSethsiPodz]

Eat Big Cock!!

[BlueBluby]

Would that curcuit work without the resistors (with a smaller voltage ofc)

[youaresosolame]

WHY ARE WE HERE NO BODYKNOWS THE ANSWER

[myguitardidyermom12]

sounds like a harmonic percolator 

[manolitomulat]

eat bubble cream

[matthewtchernev123]

which pins are the emmiter base and collector on the pnp transistor

[MasterThief1324]

Currrent has to travel from one probe to another for the circuit to be complete right?

[MegaInventor1]

how do i read schematics

[sayrocknoanime]

43 people Eat Big Cock.

[0HK4N]

What about the BOBAFET?

XP

[FlameSwordWielder]

Most of transistors i found in the junk has ECB pinout (reading from the flat side), idk if it was more popular pinout for older transistors, but if you are testing some older transistors the "it does not matter much if it fries" way, than its one of the first pinouts to try ;-D.

[StoneFlange]

Great presentation of history and cool project!

[MegaInventor1]

@StoneFlange big time

[MegaInventor1]

@StoneFlange big time

[STREETRAT211]

the first big transistor that you laid down looks a lot like a voltage regulator

[leocechet]

@STREETRAT211 Voltage regulators are made by transisors, but it's possibly a FET.

[TheBananular]

@STREETRAT211 That transistor just look like a typical TO-220 transistor to me.

A lot of electronic components like regulators, transistors, rectifiers and integrated circuits use standard packages like the TO-220 and TO-92. The only way to be sure is by checking the datasheet :)

[BassaliskVFX]

@STREETRAT211 it can be power npn, or even power MOSFET

[DrEMplushrest]

@STREETRAT211 The same 3-pin TO220 package is used for transistors, MOSFETs and various other parts as well as for voltage regulators.

[ixamraxi]

@STREETRAT211 - I think you mean voltage regulators look a lot like high current mosfets... =)

[TheRareCode]

@STREETRAT211 Its a Transistor regulator :P

[thinkbrowner]

@STREETRAT211 That's because they're both a TO220 package

[HamenChips109]

Cookie monster ate my big cookie T_T now I can't remember about Transistor!

[kskate91]

Could i change the 2N6487 & 2N6490 transistors in a car amplifier (punch 150) for 2N6488 & 2N6491? I measured the rail voltage it had 67vDC - & +, can i ask why would they use transistors rated 60 volts 15 amps? i blew one channel so i'm repairing it.

[ToiletStruggle]

professors in school were trying to teach me how do transistors work... what they were explaining to me in 2 years, this man just explained in 9 mins!!!

[jerjanerayo]

look at 44.00 he use a transistor as a PITCH hehe

[MatrixOfDynamism]

you did not do that with a cookie, should have.

[chaddon5]

Even a Big Cookie ..........gedit?

[PopulardayOfApril]

Why does the circuit need a 100k resistor, plz explain, i really need to know.

[MrJoBilly]

that at 1:04 could be a T-Shirt...

[demil133]

things would be much different if teachers teach this way. Im not just surprised but motivated by this video.

btw the entire serie is just awesome!!!

[figgi0]

i had never seen the series, THANK YOU, great video i was impressed.

[chefranden]

I don't suppose that you could make the music quieter so that you can actually be heard. Otherwise great information. Thanks

[ChloroformUrMother]

EAT BIG COOKIES OMNOMNOM

[laztom14]

U r awesome

[Slench101]

using a small current to control a large one... how is that different from a relay?

[JustinRLynn]

@Slench101 because, unlike a relay, a transistor is continuously variable instead of just on-off.

[JustinRLynn]

@Slench101 It can also switch and vary the current much more quickly, and is solid state, so it doesn't wear out as quickly.

[vaughnboy4]

@Slench101 relay will "relay" power elsewhere the transistor will take a larger voltage and make it smaller.

[vaughnboy4]

@slench101 or just the opposite

[szaszkvacss]

agent smith o.O

[ScottieDM]

Starting at 6:13 the presenter is wrong. Increasing the base current (from base to emitter in the NPN and from emitter to base in the PNP) increases the total collector/emitter current flow (or collector to emitter in NPN and emitter to collector in PNP).

To restate this correctly: Increasing the base current increases the collector current. NPN vs PNP has nothing to do with it. In the NPN current flows in the base and collector. PNP current flows out the base and collector.

[Madnesscom9]

Damn. I watched this video a year ago and i still remember Eat Big Cookie.

[Digitalman271]

Confused about the way it works.

[warlocks970]

i love u man you can replace that sob who works as the prof. of electrical engineering in my college :)

[ButtersROFL]

i have a "transistor" from a old pc power supply but it seems to be different theres i a symbol on it --->IoI<--- what does this mean? pls answear!..oh and btw. Great Video!

[CheezWhiz127]

at 0:30 what is that song you play?

[MadMurphyGames]

Very helpful.

[hazzks]

@NACHOice97 Take ur comment back to rwj please.

[scej79]

So is this basically a continuity tester?

[TheCodingProductions]

Could the probes be replaced with a photoresistor?

[nikoluka]

@TheCodingProductions Why not,I don't see a reason it wouldn't be possible.

[TheCodingProductions]

@nikoluka Interesting, would work for a nice and simple solar circuit.

[ActiveStorage]

what about the crystal radio? ppl were using "transistor" technology for a while eh?

[TeddyBear1111998]

Thumbs up if after watching this you are gonna go Eat a Big Cookie !

[RzXVeRSaTiiLe]

well holy barnicles batman! the inarticulate processor individualy indused quite a substansial amount of quantom physics.....

[eonfromteton]

if you were to put a speaker or piezo buzzer in place of the LED in the circuit he makes at the end, would it buzz when he touches the leads?

[dianetful]

what is the pressure controlled LED fader switch? any Romanian person around here? :P

[MultiJohn12321]

MOSFET- Metal Oxide Semiconductor Field Effect Transistor

just if anyone's wondering

[stupefythyself]

Thanks for the vid!!! I really liked it.

[rockerzac99]

LONG LIVE VACUUM TUBES! But transistors are smaller, more convenient and less dangerous and touchy. Still, VACUUM TUBES RULE!

[321beyblade1]

you make can make the jfet

[jojonobo]

this guy is the sh!t, he lames it all down and still keeps it interisting.Thank you. Keep on teaching.

[powaybob]

Very good info. Why do we need loud music in the background???

[CassetteMaster]

He must have a very low skin resistance or be sweating, as when I built it, it was not nearly as easy to get the LED to glow.

[KRAYSLiCK999]

ahahaha THIS MADE MY DAY ''EAT BIG COOKIE'' nice vids man!!

[remzi133]

Eat Big Capacitor

[a4d2d0]

So would I be right that transistors can work kind of like the overflow drainage-hole on a sink. When the flow of electrons reach a certain point, they 'jump the gap' and current flows to another component to complete a task? I am super new at this stuff so am I right?

[HDXLH1200]

Enable Big Current!

[Lili0000007]

You are the cooooooooooooooolest dude ever =D

[DulceJaja]

i love your videos <3

[academysoccer20]

you are bipolar

[pinjimandvakito]

[ciprianwiner]

this is almost like a joule thief because you can put a finger on the led lead and it lights up:D

[israelstamp]

Source-Emitter (Arrow)

Drain- Collector

[cappydawg]

PLEASE HELP: In a MOSFET the terminals are labeled Gate Drain and Source... What are the equivalent Terminals in a BJT?? I always that that the Drain is the Emitter and The Source is the Collector but now i'm not sure.... PLEASE HELP ME :P

[TenFoldDamage]

@cappydawg gate - base

Source -emitter

Drain - collector

[BlueBajs]

Collin is such a pussy magnet

[labstars5]

this guy.. is to exiting for me.. do you have some one a lill bit more BORING..

[kght222]

heh "eat big cookie, or something similar" well i wonder whatever that something similar could be =P

[ym160]

the jfet mosfet and bobafet

[SpecklePattern]

As a student, I always had trouble remembering the order for the transistor leads, but now, I will always and forever, READ DATASHEETS ALWAYS

[iggy151]

MOSFET: Metal Oxide Semicondoctor Field Effect Transistor, in case anyone was wondering. :)

[TechBoywii]

yay 1001'th like lol Eat Big Cookie

[shotgunndunn]

Mis-ter And-erson.

[Thecrazymerio]

@shotgunndunn holy shit...he looks just like that guy...

[shotgunndunn]

@Thecrazymerio He dos look a bit like him. I was commenting on his vocal inflections. He... Helps his... land-lady..., take out, the garrrrbage...

[ViciousBrooke]

I seriously think Im in love with you Collin,Why are you married already :C lol

[shotgunndunn]

@ViciousBrooke I wish my wife would appreciate my technical genius!!!

[GW1OII]

@shotgunndunn Mine just enjoys my skill as an engineer :-o

[mondays89]

Could someone please explain this to me. Transistors seem to be so complex. I know you can use them to switch a circuit on and off with a low voltage source but how would I hook up a low voltage power supply to a transistor to switch a higher voltage circuit on and off?

[amigos1996]

seems that 39 ppl still got an f on their E1, E2 quis lol

[PyroCube]

Eat big cookie:)

[ibanezman007]

@PyroCube Don't mind if I do!

[davesnijder]

lol made that lil thing:P its actually quite funny screwing around with it:P

[markiduval]

I like this. Very helpful. Thanks.

[itzjoeyppl]

oscilly thing?

[itzjoeyppl]

the thin in the backround with the green screen changes in different videos...

[iggyds89]

@itzjoeyppl  it's an oscilloscope to view audio waveforms for example
