  In my 79 years of attending classes, primary, military, and advanced education, I've never had an instructor who presented as well as yourself. Thank you for sharing you time and knowledge.

  Holy crap, your lab is like a submarine sonar room. I love it.

  I preached on this subject of outside foil for decades and was called a heretic. <br>&quot;Outside foil to ground&quot;<br>Thank you for this good video! &nbsp;👍

  Wow! I never thought about how the physical construction of a cap would interact with nearby fields. 40 years in electronics engineering and I learned something new from this video! Thank you Mr. Carlson.

  This is mindblowingly professional. I&apos;m nowhere near doing any of this but I really appreciate the way it&apos;s presented and the thoroughness of your videos! Your work is impeccable!

  Holy Cow!! &nbsp;52 years as an electrical/systems/test/hobbyist engineer (analog and digital) with a BSEE and MSCS and I NEVER KNEW THIS. &nbsp;An outstanding explanation that explains why a troublesome noise issue is occasionally fixed by simply replacing what appears to be a perfectly good capacitor. &nbsp;If the band marking is only randomly the outer layer (and it&apos;s obvious in retrospect that it happens because the marking is being done last on caps that are dumped onto various conveyor belts during manufacturing - Duh!!) I&apos;m astounded that sensitive circuits work as well as they do. &nbsp;I doubt that one engineer in a hundred knows this. &nbsp;Thanks for the great explanation, great design process and an outstanding little test tool.

  My dad worked at Western Electric and Bell Labs, retired in &apos;69. &nbsp;He taught me about the foil. &nbsp;This is a great refresher, and shows the reason it is important. &nbsp;Nice job.

  Thank you sir! I&apos;ve been doing electronics since I started aged 8, in 1965. (60 years!). And I never encountered this quirk! It is so obvious, now that I consider it, that it is such a puzzle that I did not.

  I must say, I took electronics in 1980. We started with tube theory and then semiconductors, and your knowledge is light years ahead of any instructors i ever had!!! I&apos;m almost 60 now, and am still learning stuff from you! keep it up!

  Where was &nbsp;Mr. Carlson when I was in college. To be so young, and have so much knowledge, and able to explain everything in a way that anyone can capture his meanings. &nbsp;As an Engineer (retired NASA), watching his video&apos;s are not only informative, but enjoyable. I&apos;m 74 years old, and when first starting my career, everything was tube technology. I had to learn with the changing of times as we moved into germanium, to silicon, and some SMT (luckily, I retired before it got to heavy). The transition wasn&apos;t easy &nbsp;for me, the professor&apos;s I had moved at a very fast pace, and you either got it, or with help from other students in the class, did the best you could. The actual knowledge came from the field where you used what little you had learned, and hands on taught you. I hope Mr. Carlson stays on line, I really enjoy the video&apos;s and his skills.

  I had no idea this was even an issue. &nbsp;After watching this video, it makes perfect sense. &nbsp;Thanks for education!
