I have always understood H-bridges a little bit, but never thoroughly. So often with electronics, people trying to teach, talk as if they're explaining what they know to another person who already understands it. In which case, it's a great explanation. But very few people ever explain things to me in a way that I can understand it *before* I can understand it, which is, of course, the whole point. Few people even understand the difference. You do. Thank you for taking the time.

[@naboo4068]

You literally teach EE concepts better than any of my college professors. Keep making videos!

[@MrRoyzalis]

He's back. Unlike most people who don't bother to take the time to make their KZbin videos succinct, you are on the opposite end of the spectrum and it is appreciated. Your videos = greatest info per minute of video and wasted time < 1%. I'm in on your Amazon thing.

[@bain5872]

From an old school audio tech I'd like to say, you did an outstanding job here! I know this does not apply directly to your video but rings true to the H-bridge. Back when I was learning analog electronics, in the day, I would have never imagined a motor controller delivering audio to a speaker but here we are. I enjoyed watching.

[@AKA0987]

Afrotechmods, You have no clue how valuable your videos have been to all of us. We're so glad you're back and just let us know if there's anything we can do to help keep you hear teaching us more about electronics.

[@Afrotechmods]

Thank you! In terms of what you can do, I need to find a way to make a living off this thing and right now I'm not even close. In the video description section I describe a few ways you can support me. If you use my amazon affiliates link, you don't even have to spend any extra money - stuff you would have bought from amazon anyway will end up giving me a pretty nice commission.

[@AKA0987]

Oops, read the full video description and got my question answered.

[@AKA0987]

Afrotechmods I know you can make a living off this content. Your education is very apparent in your content and that's something your competition clearly lacks. The money in ad revenue is there and I think you're already out to a great start on your views/ subscribers. i'll make sure to use your amazon link and I don't mind shooting you a few bucks now and again.

[@Afrotechmods]

Max Goodman woohoo thanks Max!!

[@TedsWorld101]

I’m so upset I didn’t come across this channel 5-6 years ago when I did my BSEE. This guy teaches these lab topics so well!

[@flyingfox8072]

I am from non English speaking country. Your English is not only very clear, it is sweet. Explanation was fantastic. All doubts about the H Bridge are cleared. I am in love with the channel. Thanks

[@ataraxic89]

OMG IM SO HAPPY!!! Its been two years! Since I first found this channel I have become a sophomore studying computer engineering! Your videos have really given me a head start on understanding electronics and all that good stuff.

[@MegaMechatronics]

He's alive!!!!!! AFROTECHMODS is back and we like very much.

[@PaulRogalinski]

Welcome back! Missed your excellent tutorials.Thank you!

[@HeilmanHackatronics]

Great, Wish I had some P channel MOSFETs

[@ntomata0002]

Matt Heilman You can use N channel MOSFETs in every position in the bridge, but not with this triggering method.

[@HeilmanHackatronics]

ntomata0002 Yeah... just looks like I will need another power supply to trigger the top 2 MOSFETs.

[@spiros1994]

you are great! nice to have you back in action!

[@w2aew]

Nice to see you back! Very nice tutorial on the basics of an H-Bridge circuit. I'm still running about 8-9dB lower in subscribers than you - I've got a ways to go!

[@Afrotechmods]

Bumped you up on my channel links page - hope that helps!

[@Elios0000]

Afrotechmods hey any chance of some videos on DC brush-less motor controllers

[@specialks1953]

Welcome back! I enjoy your videos. Nice to see you posting this. I hope you are able to post more of them. I like the channel name as well. lol

[@bkupiec]

Glad that you came back. Please don't make us wait two years until the next video!

[@nibrobb]

After two years. It's good to have you back!

[@viquem02]

Well explanied tutorial and explanations are easy to understand. You have the talent Afrotechmods and we thank you for sharing your knowledge here. Kudos.

[@YashKudale]

I am really happy to see you back in action.

[@christheother9088]

Great to have you back. And I was just looking for an H Bridge circuit to try.

[@SirArghPirate]

Glad to see you're back. I've learned a lot from your earlier videos.

[@nagrom97]

So happy to see you back on KZbin. Just recently discovered you and was amazed by your content - but dissapointed when I discovered that you hadn't posted in 2 years.

[@jimadams2473]

Man, you have some of the BEST instructional videos on the web. I love this one on H-bridges. Thanks.

[@ThePwnageHobo]

The best thing about your tutorials is something always goes bang.

[@Crimsonwrath1]

Glad you're back. I look forward to seeing more of your videos with your humor.

[@incubusmuchemi]

I’m a software developer and I came here to kinda relax my brain a little. Now my brain is more tired than it originally was. In another life, I’d like to be an electrical engineer.

[@thunderbolt997]

im educated in electronics and would like to learn software development and database server management

[@deankay4434]

I am a retired ASE Master Tech who is trying to fabricate a way to do nothing. So I went to the garage, turn the door lock around to my side, welded hinges and screwed the door on & locked it. Crap, my wife is yelling the ice cube make broke! HELP ;(. I am tired of fixing things...

[@sebaocano3]

Great seen you back on KZbin, you videos are awesome! Thankyou from Argentina

[@CoolDudeClem]

Yay you're back!

[@AlexOzer]

So glad you're back, it's kind of strange I decided to revisit your channel today and you just posted a video after 2 years... but seriously, keep up the great work here.

[@DarkAvatar1313]

Welcome Back, it's been awhile, glad to see you back. Thanks!

[@TheOldmankk]

Oh man, grand master you have been missing for years. Welcome back guru.

[@universalsailor]

Far and away the best electronics stop on the entire KZbin railway.

[@N4PJA]

Holy freaking cow. Thank god for these vids coming back.

[@TabletopJunkie]

Thanks for returning to KZbin!!! Love your stuff.

[@thebcd04]

Your back!!!! Your videos are informative and funny. Glad to see you're back.

[@getbusy21]

You are no longer allowed to take a break, ever! thanks for the vids

[@AsbjrnKyhlPaulsen]

Thanks for sharing your knowledge by clever combinations of pictures, diagrams and the interaction with controls and reading on your oscilloscope. Your videos made me survive an examination in electronics on uni.

[@jaguarv12593]

Glad your back! Where have you been ? Really pleased your still making videos again.

[@billlunney]

Best news of the day. You're back! Hope this is back to a regular thing.

[@hohowtf]

Thank you! Turning all four MOSFETS on at the same time made my day =)

[@Mb0ts]

finally new video from afrotech. So glad to see it.

[@dagobertkrikelin1587]

I've missed your antics so much - you rule, Afroman!

[@RyanJensenEE]

He's Back! This video is really nicely done (as per usual). Thanks for uploading, Afrotechmods!

[@TDDMS]

Glad to see you're back!

[@Sevalecan]

"STOP WHINING... I can't..." Been like 2 years since you posted a video, but I'm glad you and your sense of humor is back.

[@bumelant]

Woo! Afrotechmods came back with glory! Great tutorial! Keep it going!

[@MrPolymath0]

Yes, hes back! It only took 13.8 billion years, but hes back!

[@HakureiMikko]

OMG! Welcome back Afroman! Best EE tutor on KZbin..

[@TheBackyardChemist]

Nice video man, maybe you could make a video on improving this circuit, for example eliminating the whine, and maybe elaborating on how to choose a different FET and why you choosen these particular resistor values, and how would different components alter the behavior of the circuit. A bit more advanced topic, but I think it would be worthwhile to dig a bit deeper.

[@kisuontosikiva]

favorite electronics youtuber is back! awesome! I hope you continue making more videos!

[@IntegralMoon]

It's great to see you back! I've really missed your videos. This is great! Thanks a million :)

[@reactor1system]

It's so exciting to see you back! I love your tutorials. Long live afrotechmods!

[@kvmdop]

Another really great video, minus the rambling "ums and ahs"! Sweat, to the point and totally clear - what more can one ask for! Please keep doing more :-)

[@JonathanAnon]

Where have you been .. my learning has been on hold for two years!! Seriously though, great to see you back, love the videos...

[@skanwank]

You've got a great voice for this. These are really good videos.

[@TheTomtom898]

Fly back diodes are incorporated in the fets, welcome back love the vids!!!

[@MyBigThing2010]

man...your videos are THE shit! spot on, easy to UNDERSTAND, easy to follow and easy to "rewind" n access specific info. no bull crap filler, good occasional humor and always SOLID FUNDAMENTAL INFORMATION! Great use of my time and throttled mobile connection EVERY SINGLE TIME I decide to click on an Afro! I appreciate the channel, the content, your knowledge & TIME! Thank YOU!

[@Afrotechmods]

[@theoldwizard998]

I'm glad I kept your kept your channel on my subscriber list ! Very nice intro to H bridges ! Love the "fireworks" ! I hope "newbies" don't try to go too far upscale as there a lot of things that can go wrong with higher loads. Maybe a second video showing how to get rid of the "whine" ?

[@barryg41]

Niiiice!!! Afrotechmods is Alive!!! Welcome back Dude.

[@Okoboji15]

Great to have you back.

Glad to see you are back! Great video as always!

[@shaggy413x]

Oh boy, I recently subscribed, but then noticed the date of the last video and assumed this channel would never be updated ever again. Glad to be wrong.

[@Bulgdoom]

"Give it up for my Mainnnn man Afrotech, you better learn ALLLL about it because its all well important innit?!" What Ali G would say

[@BrendanNutley]

Always enjoy, Your explanation of your work is very easy to listen to and follow, Thanks again!

[@DUNDUA2]

Nice to see you back on KZbin

[@PaulHuininken]

Thank you for being back.

[@jeffreyangell6409]

Haven't seen the video yet but I know it will be awesome. You are by far my favorite electronics tutorial guy! I am really glad to see the post. Keep it up, you're awesome.

[@Pigeon_FX]

BUGGER ME, HE IS ALIVEEEEEE!

[@SparkysWidgets]

Great to see another video!! You are pretty much why I started my channel!

[@dl8cy]

I am very very glad that you came back .... 1000s of people missed you on youtube THANKS FOR COMMING BACK! Enjoy my beer i've send you via paypal :-)

[@Afrotechmods]

$5.55 hahaha man I laughed hard! Thanks!

[@FarmerJohn4613]

Welcome back, great instruction video as usual.

[@pji6494]

Glad Afro is back!

[@JGonzo2008]

Welcome back! Looking forward to more awesome spins on electrical education!

[@charlottelondyn805]

I have a schematic for a two motor driver that uses the LM555 timer IC in an astable configuration and a single N-channel MOSFET (because I only want it in one direction), however its power supply is two 12V lead acid batteries is series, which means that I need to turn that into stable voltage of 24V likely using a buck-boost converter. Is there anything else in particular that you'd suggest?

[@trance183]

your back!!!! been waiting a long time. thank you for blessing us with your videos. :)

[@Axeltreman]

Afro, you are alive! ,it's alive!. Now lets back to work...

[@jcims]

w00h00! thanks for coming back!

[@patrickfougere0001]

Its good to see you making videos again!!! I've learned a lot from you in the past year. And I am subscribed!!

[@sarcosmic-]

Hey man, I'm sorry for my ignorance, I am learning electronics. The voltage divider circuit at 2:47 wouldn't result in 0.25v at that point? Thanks

[@thegr81337]

Welcome back! So... was anyone else's first thought "vibrator "? I mean, electric screwdriver or car would work too... but I can't be the only one thinking dirty, right?
