    Thank you for demonstrating at 2:42 how sensitive MOSFETS with floating pins are, I always hear about using a pull-down resistor to fix them but never saw it inaction.

    I just don't understand why you don't have at least a million subscribers. These are extremely high quality videos, short and to the point, with tons of information. Love your videos man

      Thanks mate, I guess electronics is simply not mainstream.

    • @joelhowell5402
      @joelhowell5402 8 лет назад +18

      It should be, screw gaming channels, I mean I actually get to learn something interesting from your videos. They really are inspiring me to go into computer/electrical engineering.

    • @joelhowell5402
      @joelhowell5402 8 лет назад +3

      +David Serrano I understand most of what says and goes over in his videos. What other channels produce short, quick , quality clips of information.

    • @dargmuesli
      @dargmuesli 8 лет назад +5

      Cuz there are not many people like me for example, who don't get a single word of what he says but still watch the video :D

    • @joelhowell5402
      @joelhowell5402 8 лет назад +6

      +Dargmuesli His videos are great to watch, especially to see what he makes. it doesn't matter if you don't understand completely, as long as you take an interest in what he's doing.

    I had difficulty following this. I'll try rewatching and following along at home and see if that helps. thanks for your videos, even when I am confused, I enjoy learning there is more to things than a couple of steps.

    Took a while, but I managed to make a mosfet driver... And now I understand why I burned a lot of mosfet in this past... Damn internal capacitance

  • @matambale
    @matambale 2 года назад +6

    @3:48, P-Channel MOSFET, you say voltage on the gate (VGS) shuts off the MOSFET, but the scope shows the opposite behavior.

    frankly, i didn't understand much when i first saw this video, but after learning this concept in class and then coming back here helped me completely understand mosfets
    this learning process of practical after theory works best for me
    thank you for creating such video

  • @gregorycain8566
    @gregorycain8566 8 лет назад +1

    I really enjoy your videos.
    I learned electronic principles years ago, but much of what I learned has regressed to where I only remember how isolated components work, but not necessarily how they affect circuits when combined with other components. I'd really enjoy hearing you walk through the theory of operation for a simple circuit explaining how the current flows and is affected by each segment through the circuit. Just in case you are ever looking for a topic your audience would enjoy... I'd vote for this :-)
    Keep up the great work!

  • @VAB1990
    @VAB1990 3 года назад +1

    I would really like it if the information would have been stretched to about twice of the length of the video. To do that, maybe you can talk about the values you underline after you mention them. For example, while you are underlining Vth and saying "MOSFET has to cross the threshold voltage at the gate to operate" Instead use a short clip while stating the line above and then use the datasheet video clip while stating the values and how they relate to your circuit you are currently working on. I know that this might increase your work per video but you can maybe put one more short 5 sec add to make up for your extra efforts.
