[@dutt_arka]

Thank You so much for mentioning Sir Jagadish Ch. Bose! As an electronic engineer and an Indian, I was surprised at his contributions to Radio Physics,and I'm even more surprised by his name being mentioned here!

[@satishm4635]

Even I am surprised

[@freon500]

Your pre-production and post-production work as well as your actual on set work is very through and the outcome, no surprise, is that your videos are the coolest! The fact that you actually answer questions is,... the cherry on top!

[@darksantos1]

I like how he starts his videos, it is really good transition to a subject.

[@dabulls1g]

If you’ve never seen “Good Eats” hosted by Alton Brown, you should check it out. You’ll like those intros too!

[@guitarstrings4729]

Hi Collin, I really enjoy watching your videos! Thank you for helping me with electronics.

[@Maffoo]

This video makes me want to smoke a blunt and play with oscillators. If only I could grow sideburns, sigh.

[@MyBigThing2010]

Rodney Toussaint diodes use doping and oscillators use diodes...Collin had sideburns and plays with doped diodes ...it's the diodes that are doped..not the one with sideburns playing with oscillators

[@GeorgeVanAken]

You have explained a diode in simple to understand terms. I am very impressed. Dude, you rock! Going to watch the other four now!!

[@stevejackson5529]

Collin, you've made my life, YOU'VE TURNED IT UPSIDE DOWN! you helped me through my yr 10 Tech test!!!!!!

[@plwalker59]

was recommended your videos by my course tutor whilst studying for my intermediate ham exam. It was a good recommendation. Your videos are clear and precise and fun to watch , and, are a great help..thanks.

[@Humor4life12]

I love these videos! Keep them coming Collin!

[@BrankaParlic]

I love the whole series (LED, Transistor, Resistor, Capacitor and now the Diode...) I really hope to see more. I am very Interested in electronic and also a beginner so this is of great help to me! Keep up the good work and I hope I will see another video in a few weeks! Thanks!

[@AliDinkles]

Excellent! One of the bits of information I was looking for. Thank you. It was well presented too.

[@ShadowMarioid]

I had to pause this video for like ten minutes just to go over, in my head, all the things that now totally make sense

[@JamesBrowningII]

please make more vids like this. This was very cool and informative. I love history like this! Great job!

[@yesschembri]

Yep got that right! But it only creates half wave rectification (search it on google ), you actually need four diodes to turn AC to a 'nicer' DC voltage (full wave rectification with a bridge rectifier). May also add smoothing capacitors for a smoother output. Cheers, some Great videos to watch here :)

[@monelfunkawitz3966]

I hooked up an LED backwards and it sucked all the light out of the room.

[@guyclykos]

So that's how Dumbledore's deluminator works

[@michaelteel4917]

Ha

[@kenmore01]

My wife tried to make anti matter in the kitchen, but she ran out of counterspace.

[@kickpublishing]

I think this guy now does hits for Marsellus Wallace

[@DavidGalloway]

Great video. I wish it was longer...

[@tonywright8294]

Run it at a slower speed !

[@in_sympathy]

Where is this dude nowadays with those awesome videos? 😲

[@in_sympathy]

@PROJEX HIVE I actually been looking for him and failed to find 🤷🏻‍♂️

[@adrielrugay1296]

Your explanations are very helpful. Thank you. P.S. Background music was catchy. Made my head bop during the video. Lol

[@OzClawhammer]

Outstanding..love the tie!

[@MrBigTubs]

I'd love to hang out with this guy for a day, I would learn so much..I guess I'll just have to watch all of his videos :/ lol

[@redfire0711]

Cool sound and text. Well done.

[@Postscript624]

Dude, several people contribute to Make Magazine's youtube account, this guy just does these lectures. And this is really interesting!

[@crosenblum]

great video...well spoken, good history. interesting stuff.

[@SkyWolf1378]

Great video. That really helps! Thank you and good work!

[@MrVaunorage]

This guy is amazing!!

[@Billygoatmanstan]

Thanks. Awesome lessons.

[@EstabonV]

3:41 "...but few at the time understood the potential there." Ah... Ha... Ha. Hem.

[@kenmore01]

You didn't mention Schottky diodes. When you need super fast diodes, those are the ones! They tend to have voltage limitations of at best (last time I looked) 100V, but I found in repetitive applications like high frequency signals, you can series them and the capacitance (which is also relatively high), balances them. They basically have NO recovery time. Even if you hit breakdown, the offending diode (I say that with great affection for the diodes) will conduct more, thus causing the other series one to take on more voltage. No failure. Plus, they only usually have like 0.3V forward voltage which is half of a normal silicon diode. Lots of capacitance, but in a high powered circuit, that's not really much of a problem.

[@lolada1163]

great work!! i learned a lot.. continue this kind of videos.. it´s usefull to peolple that want to begin studing electronics..

[@cultuuedpetri]

These videos are on point.

[@HendoGaming90]

Nice chops dude and your suit is excellent as well. A true Blues Brothers fan huh? Awesome video.

[@ReapingMiner]

Is it just me or is the diode at the end of the video placed in reverse? The band marking should point to the diode "exit"/"negative" pole right? Yet, he plugs the banded pin in the positive rail on the breadboard.

[@AndyCAgi]

Resistors, capacitors, diodes,transistors... im learning bout this stuff in school and i found it so boring there. But these vids give it a strange .... spirit that makes me understand it better... :D

[@NadaII]

Collin needs to embrace the baldness and go full Lex Luther.

[@danijel124]

He should keep those sideburns tho ....

[@NadaII]

I concur.

[@FlamingCuntLips]

Great video, hope to see more... espicially with helpful tips about circuit building :D

[@rudyivancin]

thanks dude. you really helped me out!

[@AxelTiger]

Thanks for the info mate! very helpfull!

[@pinochska]

the phosphorus included in he LED makes it emit light, phosphorus and light get along very well

[@Bowie161]

Make your own channel and I will be a loyal subscriber. I have watched almost all of your vids. Great work!

[@SteveLloyd]

@MandrewP Its called a reverse protection diode, it shorts the supply when the supply is connected the wrong way preventing the rest of the circuit from the wrong polarity supply.

[@ASTRO_NAUTIKAL]

i dig the style freaking rad

[@lordmarshall1139]

good stuff man

[@Alkatross]

hey, good info, thanks for the lesson

[@Timaiii]

I like your videos! Good job!

[@STObon2ORZ]

Thanks for the info!

[@AximVidya]

You should definitely do more of those component-videos. For example, how bout a fransformator?

[@BerylBite]

you guys are awesome

[@thomasalexander1563]

Watch all Colin Lab's playlist,, Thank you for all amazing contents..

[@MatthewMusician]

Bro, we Love you.

[@25beanman]

i wish my school taught us all that. i had to learn it on my own time. this stuffs more fun than school anyways

[@MDNAIMUDDIN]

amazing video

[@ryder4lyfe15]

love these videos, good job. why not do one on PIC chips, just basic microcontrollers, itd be pretty informative.

[@Paul_Bearden]

You should not use a Power silicon pn junction diode in series with your main power rail, it has a voltage drop of 0.3 v. Only use them when needed, for rectifying AC to DC, flyback voltage, etc.

[@anasarkawi4331]

Great Video

[@IkaikaArnado]

this channel is awesome. it's like 90s public TV. I wanna smoke weed and binge watch this...

[@IkaikaArnado]

Idiot

[@IkaikaArnado]

I know...

Dats right biotch!

[@fabiuh991]

i just luv this guy

[@AustinIsTheGreatests]

Shout out to my professor for ECE110 pre lab 7

[@peguinman2616]

Checked!

[@andresilva8444]

Came across this while searching for how to bend the legs of a glass diode without breaking the glass. Loved it, subscribed to the channel, but still don't know. I need to install it in a pcb, got a couple of mm either side of the glass. Can anyone help? Thanks

[@markfilletti9941]

I wish you were my teacher !!! i understand when you explain thing!!!

[@TheCrazyStudent]

I've heard that many diodes have a voltage drop around 0.7 volts. If I want to use a diode as a polarity protector like explained at the end of this video, won't a circuit powered with 5 volts only get a 4.3 volt supply? How do I prevent this from happening? Are there diodes available with very low voltage drop?

[@tonywright8294]

No

[@tennisthehilife]

I think I see it. 1st row(red) = chips positive terminal 2nd row(blue) = voltage source Diode is between 1st and 2nd. So circuit goes: voltage source -> diode -> chips positive terminal -> rest of circuit -> then back to ground/source

[@componentexplosion]

Thanks Make good video.

[@iggy151]

@shmexy030 Depending upon what type of diode it is, how much voltage is passing through it, the rating of the LED, etc.

[@codecxo]

@pinochska & @0Sebek0 No Phosphor is in an LED. Usually just silicon carbide or some other semi conductive material.

[@charlesheltyskeltymanson]

Why is everyone hating this guy? I think it's fun to watch these types of videos.

[@shotox21]

Best freakin video on KZbin.

[@luftman10]

excelent video . i have a question i made a solar panel of 200 watts what kind of diode i have to used ? thank you

[@Gio.design]

what rectifier diodes shoud i use to prvent 5v current from going back .............. and which side lets the current flow

[@grendelee]

LOL he looked genuinely surprised at the beginning

[@TheRobotsofDawn]

This dude is my hero

[@AeonFlexMusic]

anyone know where i can buy bulk diodes and transistors (8-10m??) im trying to make the ironman suit

[@Greeneyehawk13]

awesome, thank you so much

[@franciscosanchez9406]

hi, how do i know which diodes can i use to protect my solar panel?

[@lucasmontec]

OOOO MORE MORE MORE!!! IM EATING ALL OF THEM! great videos!

[@canithappen]

amazing!

[@GustavoMerchan79]

great vids! please explain how that connecting grid works ... :D

[@michael1234252]

the song at the beginning is called space oddity by David Bowie

[@pinochska]

@GW1OII not only for a color change... it is added to create the light.. to bring it from a shorter wavelength to a larger one... an led will NOT emit light just by having a pn junction come on

[@sachiperez]

Awesome!

[@ponkiebonk]

if you made a bucket diode what important ingredients would be used?

[@perthbiker2661]

Hi mate I have a Cheap 5v 7W portable solar panel to charge my devices,works well, but I think that when the sun goes down and solar panel output dropped with my device still connected to the panel for a few hrs , my device battery went flat, think I need to make a connector with diode to stop this happening what diode would I need for 5V 7Watt output

[@MyBigThing2010]

perthbiker 1n5817 are commonly used in small solar panels

[@DomDollx]

good stuff. thnx

[@Loafy23]

It would have to be pretty low voltage but yeah, I guess you could. Of course you'd have the drop across the LED as a loss.

[@kdc43]

Hey Yama and Hardt............why all the hate towards the host. He did a good job and if you guys think you can make a better video, post one so I can laugh at it cuz it's so lame.

[@dave60707]

Excellent

[@AxelTiger]

is the p-type and N-type materials used in Diodes the same, if not similar to those used in 'pnp' and 'npn' transistors?

[@SteveLloyd]

@pprinceton11 All PN junctions (Diodes) Emit photons some in the visible range that you can see, LED are constructed with the junction exposed under a lens, where as a simple diode is encased in a non-transparent plastic case so the photons cant bee seen. this is a simplistic overview and you must take into account the voltage across the diode junction.

[@histand]

Extremely useful for inspiration and reminding. Thanks! If you need a cartoon or illustration for your videos, let me know!

[@1912RamblerFan01]

Those Radio's that Recieve Radio waves using a Galena Crystal is called a Crystal Radio. I'm actually building a Crystal Radio now using a "1N34A" Geranium Diode and a 365pF Air Variable Capacitor, a Simple-to-Build Plastic-Core Inductor, and a High-Impedance Piezoelectric Earpiece. btw, Crystal Radio's were the First Radio's that were used in the 1910's, 1920's, and partially in the 1930's and 1940's. Crystal Radio's make their own power, however don't create alot of power.

[@tonywright8294]

You don’t have any friends do you ?

[@SnottyAust]

Good stuff, ta

[@brocksprogramming]

Can you make one of these videos on oscillators?

[@brandon20904]

awesome

[@larryshaver3568]

would a !N34a be considered a point contact diode?

[@AeonFlexMusic]

what are the physics behind the diode's reverse bias characteristics

[@atomicpineapples]

This guy is so awkward, I love it! Reminds me of myself...

[@Madness832]

Love his sideburns! LOL

[@pprinceton11]

nice job... i have a question,,,last day my teacher asked me ..tell me why led(light emmitting diode) glows and simple diode >l doesnt glow,,,,but i couldn't gave the answer,,,please tell me the difference between them and why led glows and simple diode does not glow....

[@MrfixitRick]

Cool! The un-powered diode crystal radio circuit, with only a resistor, a couple of capacitors and a coil added to the diode, is capable of incredible feats. The same basic diode radio circuit, plugged directly into a computer, can act as an EM field detector, a light-sensitive discriminator, or even a microphone. The circuit can be also tweaked to act as a beta brain-wave modifier to allow better use of alpha and theta brain wave states. Check out my Spirit Radio playlist for experiments.

[@jacobanderson6073]

what kind of surface is that table? I want one!
