Thank u max!

Just catching up

Thanks Max for giving overview of Basic of Electronics.

I've seen some error in Transistor introduction, It should be Bipolar Junction Transistor(BJT). FET are voltage controlled device & formed by different process. 

Thank you Maxfield

Wonderful refreshment course of electronics fundamentals

My analogy of voltage, current and resistance were based/compared with river flow through some channels

Hello to archives knowledge

Thank you for archiving this.  It is always good to brush up.

I started studying electronics 3 years ago as something to do during recovery from surgery. I studied long, not really too hard, and received my Extra class ham radio license. Much of what was covered today I just learned recently while preparing for the ham exams. This is  an excellent refresher, and at my age (65), refreshment helps. Thanks for presenting this for free. Max is very good a teacher. 

Good refresher

Hello.

Great presentation - lots of information I haven't used in years!

updated adobe flash player 11 to hear audio on new Win 7 64 Home

Thanks Max!

thansk, done.

no, I have not seen that slide.

no specific electronic application, just an interest as a hobbyist.

listening to the archived session.

bye

See you next time.

I look forward to more

interesting first class

hi all

Audio/ Video electronics

nice fast review . Thanks Max for such a beautiful presentation.

Nice presentation and great review.  I will going through the whole series of presentations.

bye

Thank for the great presentation

no I havent seen the slide

I can hear okay

Picking up another course a bit late

belated thanks

cannot view archived for some reason?   Have taken classes before.

Who is the second voice /?

Water example for inductance - water hammer affect in pipes.

Thanks again Max for another interesting look into electronics.

Trying to catch up due to being out of town.

Thank you for the class

Thanks Max for sharing these fundamental concepts. Good refresher.

Thanks.

My powerpoint says that no text converter is available. Thus my slide is not opening!

From Basic Concepts to gates in one hour? Wow -- that's fast Max!

God basic review if you already had some of this stuff and forgot it all! :-)

Well done!

Thanks Max, for a good refresher lecture.

Good analogy of inductance, Max!

Yes, I saw the same anology as discussed in slide 7

Catching up today's lecture!

Max, when I design power supplies I'd like to know how I can use math for low loss inductors in my circuits?

Thanks, Max.  Wonderfully understandable presentation!

I think longer lectures would be beneficial

refesher course so I can rejoin the work force

bye

bye Max!

OK -- I've got to go -- C U tomorrow -- Max

GeoSei - didn't know that it was,  unless it is part of the device package in the form of BeO - berylium oxide - a super thermally conductive material which causes severe alergic reactions in some individuals, when in the form of dust.

Re Berrillium -- I think it's used as a base/substrate in high-poewer transistoirs -- but not in transistoirs we use to make logic gates and ICs

thx Max

LEDs - go to the archives here - there was a week about LEDs a few months ago

Max,

What is Berylium used for in Transistors?

TIA

Mose Si Wafers are 300m min diameter today, but some plants are now at 450mm

Speed is faster with GaAs -- but it's a much harder material to work with (also the Arsnide part is poisoness)

GaAs isn't as big a wafer though, Si up to 300mm?

LEDs are a topic for a completely separate story

silicon is very abundant - does speed increase appreciably with GaS(?)?

In the case of light-emitting diodes (LEDs) -- they use a bunch of different elements to get the different colors

good day to all

thank you 

If you take any elements in the same family as ilicons -- you can use them -- so silicon, germanium, and carbon (in th eform of diamond).  Tings like Gallium Arsnide involve mixing two different elements.

longer lectures would be great, especially with this kind of subject matter

Thank you so much. Please taske the time you need. The slides were great.

Thank you.

There's also some use of derpsiting a layer of germanium on top of silicon

Good session, thank you

Thank you

I don't mind to have a 50 minutes of lecture instead of 30 minutes. This is good way to learn things. Thanks!

In the case of ICs, Gallium Arsenide is used for really high-speed stuff

somewhere in the basement is a copy of TTL Cookbook....

regarding TTL:
I got the entire book on TTL UCY74 series and their implementation from My Father - the DSP guru :-)

ok...thank you...looking forward to the rest of your presentations

Once again -- thansk to everyone for taking the time to join me and for your very kind words

what other material, aside from silicon is being used as a substrate?

till tomorrow...

Thank You, Don't worry about time just give us information.  I like the basic start.

Re the question about Opamps -- I'm afraid not -- that woudl be a session in its own right

OK 3pm EDT..I've got to go. Thanks

Thanks

As we will se ewhen we come to discuss silicon chips -- we can now build literally billions of transistors on a single chip... it's mind-blowing...

are you going to be looking at opamps at all this week?

thanks Max, see you tomorrow.

Max, Thank you very much for the presentation. It was very informative and I enjoyed tremendously. Thanks again!! Brian

Re an Exam ... how would anyone force you to take it? (grin)

Awesome explanation.  Thank you!!

ah, thanks jl

I remember RTL and DTL and TTL .... :-)

is there a test over this material?

@dejohnny...no exam has been required in any of the past presentations/classes

It used to be easier to make PMOS transistors (but they were slower) -- just using NMOS transistors was easier -- but CMOS rules because it uses so much less power

one comment before I go about the non-complimentary logic. does anyone remember DTL or RTL?

Thanks for the presentation. Just a quick remark:
I am aware of the time constraints but I think that as the complexity of the content of the following slides goes up, the lecturer shouldn't be cutting down on time spent on those following slides - especially first diode, or transistor - as that is where first and most of the people get lost/confused with the basics of electricity, of the whole "how it works" needed for later.

@PRIMECHUCK...all presentations can be accessed in the "archive" link in themenu above

thanks again max- 

Is there an exam for this course? If so, when do we take it?

What are the advantages of CMOS NMOS and PMOS?

If we can't listen live can we still get copies of everything?

Where can I see a repeat of this.

Th egreat thing about CMOS is that it uses a lot less power because there aren;t any resisters per se

You can also make logic gates using only PMOS transistoirs and resisters...

Loud & clear

thank you for a good info

Re the question about what woudl be non-complementary -- some early ICs were NMOS only -- that is, you can form logic gates using only NMOS transistors and resisters...

Time to earn my keep. Thanks Max and Rich, see all tomorrow.

@max: so in cmos, you use both an npn fet and a pnp fet in the same circuit?  Which type conducts when the higher (Logic 1) voltage is applied?

anyone wanting to capture the audio files to save to their own storage...contact me directly

Thank you Max, looking forward to tomorrow's session

Max Mott

I think they post it for replay later

The audio will remain in the archive at least until the end of the year

Thanks

I worked for Rockwell Int Rocketdyne div in the 90s we had a program called discover E we went to schools in socal

...and Slide 27 shows how an "Easy Bake Oven" works!  (grin)   Max, you're the greatest, I really enjoy all of your material!

@krisranes ..yes all audio and slides are available thru the "archive" link above in the menus

Never hurts to have a refresher!

this was a great review...thank you

Thank you.

Really enjoyed it. See you tomorrow....same time.

Can we get the audio presentation?

What would be the opposite of CMOS?  If it's non-complementary?

That's right -- CMOS (complemnentary MOS) is NMOS and PMOS transistors connected together in a complementary manner

Thank you Max, I was cut off for a time so I will try to listen to what I missed later.

Thanks Max, very informative.

Thank you great pres.

Thanks Max

Thanks. Without the LaPlace transforms, this stuff can be pretty interesting! :0

what gives basic LED's their color?

So is there a "light" transistor in the future ?

Great educational.  Thank you, Max.

Thanks for the session ..it refreseh my mind.

You explained how capacitors work, but for what purpose would I use one? 

Thank you for the refersher.

Thanks Max!

looking forward to tomorrow's class

will any of the audio be avialable later

Thanks Max and Rich!   And thanks for letting Max finish!    Looking forward to FPGAs.

Thank you Max.  Look forward to the rest of the lectures.

Any questions?

THANK YOU MAX.

cmos is complimentary N and P mos transitors

Thank you.

Thanks dig-key too!

Outstanding job, Max.  

This presentation brings back good memories. Thanks Max!

Been doing this for a jillion years, but it's great to go over it all in one place.

I'll be keeping an archinve of is.

Thanks so much for your kind words everyone

looking forward to tomorrow and rest of week

Thanks Max, it was a nice review

thank you

Great job, Max.

Thanks Max..

Rich thank you for allowing the additional time. Thank you Digikey for sponsoring the lecture

Thank you, Max!

Great presentation!

Thank you Max, you are the best!

Max - need to get you into the high schools to make science/engineering presentations to rouse some interest!

thanks max

nice presentation

Thanks. Great review even for us EE's

Will these be posted later (in case we miss a session)?

First year of EE school without the math!

Thank you great presentation

Thank you

Looking forward to all of the presentations!

Thanks  e enjoy the presentation. Have good day

Thank you. Looking forward to the next presentations.

Thanks Max, Great refresher course. Will be back tomorrow.

See you tomorow!

thanks

Thank you very much! This was an excellent presentation, very clear and easy to understand. Outstanding job.

Thanks!

THANK YOU MAX

Are the slides available ahead of time?

Excellent introduction, thank you

Great job Max!!

Thank you to you Rich and DigiKey...fantastic how interactive presentations work

Thanks Max - the review was very good

Max thank you for the lecture

Outstanding introduction and summary of a broad subject.

Thanks Max

what is cmos again?

cheers

Nice to hear the basics from Mr. Magnificient!

thanks

thank you Max,

Thank you Max, looking forward to tomorrow's session.

very good

Thanks Max!!  Thanks Rich!

My pleasure

Thanks Max!

Great presentation.

Thanks, great class

Thanks!

Thanks very much Max, that was a good refresher !

Thanks Max!

thanks!

Good job mate

Thank you Max excelent introduction

thanks Max...greate EE intro...it's always good to review

Thanks!  Great info

tc138003 -> If its an IPHONE, use a PHOTON browser.  That is what I am currently running.

Nice review.

thanks

Thanks ... I apreciat very much! Good Jod!!!

Thanks Max

Great recipes in Beebop!!!

thank you Max. This has been good. 'looking forward to the next few days.

thanks Max

Good times had

Thanks Max

I wish my phone or IE would have worked :-(

Thanks Max!

Thank you Max! Sorry you had to rush the content. :(

thank you so much

This is fun!

Thanks for all infor and review...

thanks a lot. the presentation is really helpful

If we get cut off, watch this page for news.

Got to go this was great.

Thanks :)

Thanks Rich!

thanks Rich...greatly appreciated

Thanks! :)

Yes, please keep going

keep going!

Thank you Rich

We will let Max go as long as the system allows.

keep talking

Very interesting stuff!  I agree,keep it going.

rick.curl - audio is available in archive in an hour or so typically

good review would like to finish

I'm happy  for a little more "air" time.

Will audio archive be available later?

Rich, could we go a liitle longer? Thank you

I agree...allow Max to finish presentation in whatever time it takes

go to the end please

FYI: Slide 24

agreed.  would rather cut Q&A

Agree, go over the time, good presentation.

Mr. Maxfield, going to have to catch up on your lecture later, I hope it may be available later. Could never get audio to work, firewall too strong.

Thank you.

This is great!  Let him speak as long as possible...

Same here, please let him finish.

Yes please

go over

I'd just as soon go over also

yes, can we go over the time to hear the whole lecture?

Yes... please go over!

Moderater:  can we shorten the Q&A and let Max speak longer?

Yes, very interesting, go over.

There isn't enough time given for this lecture. I feel cheated a bit!

can we go over a little rich ?

@G Anderson, ferro meaning ferrous or iron.

@ G Anderson:  Often, but not always.  Ferrite is classified as ferro magnettic.

G Anderson - yes, like transformer lamination

Yes, ferromagnetic material is magnetic iron/steel.

ferro magnetic material a metal?

The effect know as water hammer is a manifestation of the accelerative head in of a liquid in a long tube being brought to a sudden stop.  This is analigous to sudden the voltage spike that is observed accross a switching device in series with an inductor after the switch is shut off.

remember the water chart from either ee101 or physics 101

inductance...    "peer pressure"

I've seen the water analogy before.

you need a larger resistor for the 2.5 watts.

yes, seen pressure diagram before.

Thanks dastrang! :)

"but I probably wouldn't interrupt a good presentation with a dumb poll like that..."

Same here. Seriously? Let the man talk.

show-off..

dastring: nicely done

if I had a nickel for every time I said "V = IR" I'd be a hppy man.

Electron migrate down the copper at about 13,000ft/sec. The electromagnet force (photons) move down the conductor at around 2/3 the speed of light. The photon knock the electrons off the atoms as the go. The electron move is a secondary event.

first time I've seen this analogy

yep

something similar

these interuptions are not helpful, at all

FF and chrom never loaded for me, IE did

yup...

but I probably wouldn't interrupt a good presentation with a dumb poll like that...

See similar diagrams with water/electricity analogy, but like Max's tank & pressure better than ones I saw.

@technologist.  I have the most up to date android razr maxx.  4g dual core and i click on the "live now!" link to no avail :-(

yes

I haven't, but I've always used the fluid flow analogy for EE systems.

similar diagram, but everything was in black and white back then

@rich - yes, not exact same slide but a similar picture (there was no Powerpoint when I studied EE).

Yes

Stop interupting

similar drawing

hello

looks familiar

I remember it from my freshman year in high school, aeons ago (well, 29 years anyhow)

new to me....wish I saw this in 101

Heard the analogy never seen the slide.

Yes, saw a similar image in the late 60's.   :)

hello everyone...sorry I am late

yes

Me, too!

yes

I have heard it but not this slide before.

+1

Have you seen the "water slide" before to descrive electricity?

yep

Never seen this diagram

YES

yes! this is a good anology!

maybe

Never seen this slide before... great analogy

More than once, and it still works.

yes - always a good analogy

same description, but not exactly the same slide

no, I have not seen slide 7

Yep...very familiar

Yep

Yes

yep

No, never saw it.

similar one, not exactly the same with a tank

sorta

+1

yes

Nope

@tc138003 It depends what version of Android you have, but if you have Android 3.x and at least a dual core processor and flash installed then you should be able to see this just fine

yes, learned electricity the same way with water flow and bowling ball analogies.

Do the electrons push from the negative, or are they pulled from the positive on the right?

same here - just a refresher for me... but can't miss another lecture by Max :)

does anyone know how to make this work on android?

when F5 is not doing its job, close IE, then login again.

refresher course for me... no problem listening via IE

Would be nice if a slide showed the electron shells (2 first shell, 8 next shell, etc.)

@kentj they are using the flash streaming ports so they might be blocked on your firewall

Figured it out...government employee, blogtalkradio blocked...

my company network blocks some flash, had to log out of the company VPN and now works just fine.

h o n cl br i f

nice notes on electronics

Closed and reopened browser...nothing...

thanks it was a refreshing for me

I'm in Firefox and it's working fine.

audio works for me in Chrome

@jalnc, try browser refresh

Fail.

Audio Ok in Chrome..

Dan: it gets passed this pretty quickly

Love this!  Doing great!

I don't see the message at the top that should be saying Buffering or Blog Talk Radio either.

No audio for me either, just made sure I had latest version of the player

Phooey...

...buffering still

Had to change from FF to IE to hear audio

OK, this really is the "let there be light" begining!

Receiving no sound.  Player did not initiate.

he

In the dotted circle is there always 1 -ve with 1 +ve.  It's hard to tell from the diagram. 

paveln2003: send me an email at rich.nass@ubm.com

Refreshing didnt get me audio either.

I hit refresh and still no audio

eashford: Max sounds pretty good for being 112, doesn't he?
