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!

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!

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

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

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

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

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

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.

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!

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

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

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

I love these videos! Keep them coming Collin!

I think this guy now does hits for Marsellus Wallace

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

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 :)

Outstanding..love the tie!

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

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.

This guy is amazing!!

Cool sound and text. Well done.

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

Thanks. Awesome lessons.

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

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

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

Where is this dude nowadays with those awesome videos? 😲

These videos are on point.

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

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

Great video. I wish it was longer...

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

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

i dig the style freaking rad

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

Thanks for the info mate! very helpfull!

thanks dude. you really helped me out!

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

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

Bro, we Love you.

Thanks for the info!

good stuff man

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

i just luv this guy

hey, good info, thanks for the lesson

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

Shout out to my professor for ECE110 pre lab 7

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

@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.

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

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

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.

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

you guys are awesome

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

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

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.

Great Video

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

This dude is my hero

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

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

amazing video

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

Thanks Make good video.

I like your videos! Good job!

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.

You've just helped me! I was so frustrated, I want to create a diode using fly ash

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

Best freakin video on UKposts.

Is the breaking voltage on an LED high or low?

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

awesome, thank you so much

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

LOL he looked genuinely surprised at the beginning

amazing!

@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.

Excellent

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

Awesome!

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

Dude, Collin, out of all seriousness you should make your own UKposts channel.

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

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?

good stuff. thnx

Good stuff, ta

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

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.

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

@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

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

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....

i love the side burns

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

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.

I like the song at the begging and end, do you know the name and artist.

If I'm not mistaken, isn't that diode installed in reverse? It looks like the cathode is connected to the positive supply and the anode is connected to the chip's positive supply terminal.

can you make a series on magnets. then a series on magnets AND electricity together and how they work together.?? thanks science dude!!!

I NOW FEEL LOVED.

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