In this video I do the tenth Maxitronix 20in1 Electronic Project Lab project: Speech Conductor.

In this project we learn a little about transistors, amplifiers, and astable multivibrators.

Note: while I was making this video I took a detour into making a cable, which didn’t work out. You can see the video about that over here: Extra Content #13: Failing to Attach Banana Plugs to Microphone Cables | In The Lab With Jay Jay.

In this video I announce a few things:

The definition of a “new book” is now anything published during or since the year 2000 (it used to be anything that was published within the last ten years)
The various features of the show now come with numbers per segment/feature (this is Channel News #4 for example)
There will be a new main show feature called Maths Homework which will be starting soon (I just need to get a new camera so I can record this new feature)

In this video I take a look at Electrical Engineering 101: Everything You Should Have Learned in School…but Probably Didn’t 3rd Edition written by Darren Ashby and published in 2011.

In the book the author mentioned that they used to write for chipcenter.com which appears to have since been taken over by EE Times. ChatGPT provided more information.

The author also mentioned Mathcad. I’m planning to check that out over here: https://www.mathcad.com/

And some terms which came up (ChatGPT explains further):

Vcc: Voltage at the collector
Vee: Voltage at the emitter
Vdd: Voltage at the drain
Vss: Voltage at the source
