What about the JFETs ? They can go positive or negative. Sounds manic depressive or schitz to me.

So they discovered oil and started building cars. Big deal.

And what's this approach bullshit ? Just explain how the thing works and that's that. Who Shockley was means jack shit. Where it happened means jack shit. When it happened means jack shit.

The principle that needs to be taught - bipolar transistor. You put current through the base emitter junction and it causes leakage from the collector. ALL TRANSISTORS ARE COMMON EMITTER, only its orientation with respect to common is what changes.

Ohm's law, fuck all that sigma this and delta that. Your car has two headlights. They pull 3 amps each because they are four ohms with 12 volts on them. That adds up to 36 watts because watts are amps times volts. When you have two of them in parallel it is still 12 volts but now that pair of them is pulling six amps because two four ohms in parallel comes to 2 ohms. So 12 volts times 6 amps is 72 watts for the pair.

One paragraph. Who cares who Ohm was, or Watt, or Volta. Who cares how many columbs in an amp. Who even cares if you are paying attention to electrons or holes ? Suffice it to say there are two polarities.

Are you teaching someone how to design transistors ? I kinda doubt that.

One guy I taught uses it all the time at work, and makes more money than me, GRRRR.

I am an autodidact like 90%. I agree they teach wrong. Like 180ยบ is the same as inversion. Try it with a sawtooth buddy. And they teach you about car batteries, the acid the ions and ll that shit. Fuck it, just charge it and shut up. When it doesn't take a charge either put epsom salts in it or buy a new one. Do I have to be a chemist to fix a Marantz amp ? (well actually there was this one...some other time)

Transistors. someone invented them. We got them. They work like such...and you order them online from like Digikey or Mouser, or actually Newark has been better on a couple of things. Bam. Want to know who figured it out ? I don't know the guy, and he is dead. That's it.

When i was younger I had what was called a science encyclopedia. One of those send you a volume a month. I read it cover to cover EXCEPT the bios on inventors etc. Later in life I got interested in that and read those. I found it interesting. for one, many innovators and inventors were either off the boat or first generation


here.

AND, even in the old days, some of them lived to be 80 or so. See, human life span has not gone
up, the AVERAGE lifespan has. It does not mean the same thing, it just means less people get killed
now. And now we're overpopulated, see, the old way was better.

Where's "here"?
