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

[@MattsAwesomeStuff]

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.

[@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.

[@MegaMechatronics]

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

[@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.

[@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!

[@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

[@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.

[@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!!

[@N4PJA]

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

[@jimadams2473]

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

[@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.

[@universalsailor]

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

[@spiros1994]

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

[@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

[@YashKudale]

I am really happy to see you back in action.

[@bkupiec]

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

[@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.

[@christheother9088]

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

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...

[@BrendanNutley]

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

[@SparkysWidgets]

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