noise lecture

One of my kids is very talented and passionate about electronics, but was coding web pages for a living. He loves this stuff. Another is a young girl from Mexico who was good in school but had little hands-on experience.

A third guy, also pretty fresh from school, asked some interesting questions after the main session, about how a Colpitts oscillator starts up. I showed him a class-C oscillator that won't start up but will run; he liked that.

Nobody is born with experience, and EE schools don't teach it much either.

I know a lot of stuff that they (and probably you) don't. These kinds of sessions are fun and good for morale.

Tuning the cell heights of a phased array radar panel is not an easy chore. Then begins the actual emitter/receiver transducer location positioning within each cell. That's just the Aluminum, hobbed out mechanical cell array. Tuning 'steps' can get expensive. Lots of math to assist the 'art'.

Of course you're wrong, AlwaysWrong. You always are.

Oh, God! I sure hope not!

Well, there you got me.

Not you, the AW guy.

It's coal and newspaper for... no... It's a chest gripper for you! I won't be wrong about that. You are as bad as Donald J. Trump, boy. Die, KRW, die. Then... *I* laugh.

You are both wrong.

Johnny could use a nice chest gripper myocardial too.

You are both not human.

How can one person, even one as stupid as you, *ALWAYS* be so wrong, AlwaysWrong?

Yeah, I am sure that you are in perfect health, karmasan. (in case you are slow on the uptake, that's 'sans karma') Bwuahahahaha!

Again, you're wrong. Good job, AlwaysWrong!

Stupid as a stone, too.
