Silly Job Title: Science Officer. I am the Science Officer!

In this video we wish you a Merry Christmas and a Happy New Year!

To begin with I explain the cosplay costume I wear on the show. It’s me dressed up as Egon Stetmann the Chief Scientist from StarCraft II.

We take stock of the aspirational video release cadence which at the moment is one video per day:

We have a look at the video cameras we currently have deployed in the studio. We have OBS Studio running on four different computers with camera inputs like this:

Silly Job Title: Component Wrangler. I am the Component Wrangler!

In this video we continue to work our way through Learning the Art of Electronics. We have nearly finished the 1N DC Circuits chapter. Today we learned a new rule of thumb: when circuit A drives circuit B the output impedance of circuit A should be equal to or less than 10% of the input impedance of circuit B.

There is no prac this week, only theory. Next week we will complete this chapter and then we’re ready to proceed into our first lab chapter.

Silly Job Title: Energy Elicitor. I am the Energy Elicitor!

In this video we keep on working through Learning the Art of Electronics chapter 1N DC Circuits.

There was no experiment recorded today due to time constraints. The new material covered was just a little bit regarding ground, the rest was revision. We will continue next Tuesday so stand by for that.
