Transistors and their predecessor the triode, offered a lot of possible ways to configure the basic circuit for specific results.

Needless to say, the final word on possible configurations has yet to be written.

One day I will sit down with the Art of Electronics while having SPICE open and ready. I figure running a few simulations of the example circuits will add to the experience and really nail concepts into my brain.

This an interesting subject and the video is a definite improvement, mainly in terms of the audio portion. Keep up the good work!

Hi Frank,

It was definitely interesting, great demo, and everything was clear, including audio : )

I thought you were using dedicated camera, until I read the content after viewing the video, and realized it was a camera in a phone. Great results.

Good video Frank; can I call out the lack of err’s and umm’s and fluffed lines and the sound was fine. Loved the Lego men holding the wires, start he day with a smile. You could follow up with a video showing the relative advantages/disadvantages of each approach, e.g. load regulation of a voltage divider vs, say, the forward biased diodes.

Good demonstration of current sources. I usually watch videos at double speed and in this case I can follow the video at double speed very well. At double speed you look much younger.

If you start the video with a small sample of the final demonstration with the LEDs before explaining the theory, I think you would capture even more attention. The demo is very good.

This post is hopefully of interest to some, but my other motivation is a desire to improve the quality of the videos I'm developing. I've purchased an external USB microphone and it has helped improve the audio quality in my opinion but we are still a long way from studio quality :-). The video is being shot on my iPhone. I'm using Shotcut to do the editing. Comments on how it can be improved are welcome.
