    Brilliantly explained, from creating the sub-circuit in schematics (and why we need to save the sub-circuit node voltages and currents for later probing through the symbol to be successful) to making of the symbol. Thank you so much.

    One very minor request: Please label nodes, paths, components, etc. and refer by name in your commentary. If you simply point and say "this one" or "that one" it can be tough to follow at times. Thanks!

    These videos are really good, but I expect many viewers to quit almost immediately because of the squeal. What a shame! (I found an easy fix. See end of my comment.) Nice and simple video. For newbies like me, I recommend unchecking Control Panel / Drafting System / "Automatically scroll the view". The squeal is bad but turning the volume down helped. I recommend running your audio through a notch-filter to remove it. These videos are worth the effort to remove the squeal. The squeal can easily be removed with the free Audacity program. Downloaded a portion of the audio from the beginning of the video. Be sure to start audio capture a couple of seconds before she begins speaking. Under Audacity/Effects select Noise Reduction. Select the part of the recorded audio before she speaks to allow Audacity to identify the type of noise and suggest a correction. The squeal can be completely removed with minimal effect on the speech.

    This video was great but can you please not just say "with a little bit of fanangling" and show what you actually did....? To people who are trying to mimic and follow it along, it does not help when you just randomly decide to skip a crucial step.....

      Hi, I shouldn't have mentioned the fanagling - I was referring to what is needed to be done to import third party spice models. That is a separate tutorial. Sorry for the confusion.

    Thanks alot for all of these video tutorials. I found it alot better to watch Video Eight before watching this video to be able to follow along and do the same thing. The power source is the same as in the previous videos except with a 1V AC signal on top of the 5V DC signal. The speed in which you go trough everything is great, some people dumb it down to much making it to slow, but since it is a video its easy to go back and see it again. Keep up the good work, I look forward to see any more videos you might make.
