Silly Job Title: Connector Kingpin. I am the Connector Kingpin!

In this video we continue working through Learning the Art of Electronics. Today we don’t do any course work, rather we do selected readings about current sources found in the text.

Our reading from The Art of Electronics 3ed includes:

  • §2.2.6 pg 85-87 RE: resistor and BJT current sources
  • §4.2.5 pg 228-230 RE: op-amp current sources
  • §9.3.14 pg 620-623 RE: voltage-regulator current sources

And our reading from The Art of Electronics: The x Chapters includes:

  • §2x.2 pg 103-107 RE: Current-Source Problems and Fixes
  • §2x.3 pg 108-109 RE: The Cascode Configuration

Note that the 2nd edition of the x-Chapters is available for pre-order: The Art of Electronics: The x-Chapters 2.

When we continue next week we will do the various exercises we ran out of time to do today, and build some current sources, starting probably with a BJT version.

Silly Job Title: Digital Dancer. I am the Digital Dancer!

In this video we unbox the Sharp EL-506TS scientific calculator. In this video I also mention about my Casio fx-991CW and my Sharp EL-546L.

The constants used in the calculator are taken from CODATA Recommended Values of the Fundamental Physical Constants: 2018 which is an impressive scholarly work.

I am sorry for the poor focus and zooming in this video. I have ordered a new camera which should help me to minimize issues like this in future videos.
