    I am a semi-retired electronics instructor and I am in the process of putting my curriculum online for free. I think I have a unique and useful way of explaining electronics. People commenting on my YouTube channel seem to agree. Everything is free and is suitable for students who want to learn electronics from the ground up and for instructors who want to give their students an alternate point of view. You can find my text lessons at http://rsdacademy.net. My YouTube channel is https://youtube.com/channel/UCOausWDNRDJikQ11gSLj7nA

    This is a work in progress but I have complete lessons in basic DC Circuits, AC Circuits and Solid State Devices. I am currently working on Analog Circuits. I hope people find these resources useful.

    This sounds good Robert. I might just take a peek :)

    I watched your video on transistors which is ok ish. It would be worth pointing out about ESD precautions when touching semi conductor devices and that this is just a demonstration.
    Thanks

    Hello and Welcome.

    What you are doing is a great undertaking. Many people can learn and profit from what you are doing. Electronics
    is a very good field to be in. Old and young alike will appreciate this.

    Thank you. I appreciate that.

    According to ETA International (aka the Electronics Technicians Association) there is a critical shortage of electronics technicians. The governor of New York recently declared an emergency because the operator of the subway system can't find enough qualified technicians to replace those who are retiring. ETA International is beginning a campaign to get people interested in becoming electronics technicians, but there aren't enough schools teaching electronics technology. Even if they can get people interested, there are few schools for them to learn at. I'm just trying to do my small part.

    There's a nationwide shortage of auto technicians, truck drivers, nurses etc, and they all have one thing in common, they don't pay enough to attract potential workers.
    When I was an auto technician employers thought that they are doing you a favor by offering $10 an hour for a 6 day 60 hour workweek with no benefits of any kind, and then couldn't understand why nobody would apply for the job.

    Adam,

    Thanks for the advice. I just don't want to overload beginners. When I get into MOS devices I will talk about ESD.

    Ok no probs, what you are doing is great, I wish I had this sort of thing when I was learning electronics. But as you know all components are susceptible to ESD damage, just thought I would mention it.
    Cheers

    Robert - are you interested in some critical comments to your lessons?

    Example: I strongly disagree to your headline
    The BJT as a Current-controlled Variable Resistor

    For my opinion, this is a misleading (and false) statement.
    In contrast, under certain operational conditions the FET can be used as a controlled (grounded) resistive element.
    But this does not apply to the BJT.
    In this case, the collector current should vary - according to Ohms law - in proportion to the collector-emitter voltage. But - as you certainly know - this is NOT the case.
    A device acting as a (voltage) controlled current source does not behave like a resistive element.

    For more than 25 years I also was a lecturer for analog electronics - and very often the students came to me and were asking: "I have heard that transistors can be used as externally controlled resistors - FET or BJT or both?".
    (I suppress another example, because this subject was discussed also in this forum extensively: Is the BJT current-controlled? NO it is not!).
