fundamentals series
« on: May 14, 2013, 05:19:25 pm »
I love the fundamentals series of videos, the soft latch switch is something I have always wondered how to do.

Maybe we could have a thread with ideas for fundamental videos to vote on, I know there is so much to cover and only so many fridays

I'm sure there's a topic somewhere here about suggestions  :-//

Anyway  :-/O


Dave, there are lots of newbies here asking for help building power supplies using the 317

How about a running project going back to the times when the 317 never existed  O0

Show them how they can build a through hole, simple, 741 op-amp ( there's millions of them ) a few transistors, a zener, a pot and a lying around transformer.

That'll show them; use of a reference (zener); feedback ( voltage control ) and shunt resistor for current control.

Then you could mirror to make a tracking +/- supply, simple say 500mA and +/- 12v

With that you could cover op-amps, feedback, zener voltage references and other newbie bits  :-+

Mr Smiley  :)

How about a crystal/load capacitor RTC and uC clocking tutorial?

I can use Google and even books to find out particular things because there is a lot of stuff out there.

Well that's the thing isn't it. There is essentially not much I can do that hasn't been covered already somewhere on the internet...

If the FF series is to be targeted at the non expert  viewer then I suggest keeping terms like "totem pole" out of explanations. Explaining some concept with an unexplained term doesn't add clarity.

I agree. But throwing in the term might encourage people to go "oh, I wonder what that means" and then go google it. Then 5 hours later they come up for air better educated  :-+
When I was learning electronics (before the internet and information revolution) I had no idea what some of the terms meant. But I was thankful I had heard the term because then later when I learned about it, bang, I'd remember back and everything fell into place much quicker.

Keep FF coming.  They are making us think :-+

IMO the debate about the content accuracy is healthy.  I hope it continues with more participation.

Today is Friday! Can't wait for a new episode :-)

 Sure you can find almost anything on the internet, but sometimes you need an idea what to search for...

Hi Dave,

Then do as you do now, go through what people suggest, pick a subject; your own or a suggestion and just post the video, no warnings or hints. You teach people by showing and explaining, that can't come from google, books, what people say or degree courses  :-+

A series of fundamentals, all secretly building up to a put together project, ie an op amp based psu with a good old pot. ( not the ones you smoke   O0  )

 :)

I totally agree with you Dave. The first step to learning something iis knowing what to call it. If you don't explain it then I can go to google and get an explanation or I can ask on the forum. Dumbing it down never made anyone smarter. Practical electronics is hard. I'm ok with that. I'll do the hard work.

Different engineers and different teachers use many different techniques, terminology and tools to solve problems. Watching other videos is fine but if they have a different set of tools in their lab then they may present a solution in a way which is not easy for us young players to replicate at home. My "lab" is eevblogified as is much of may component inventory. When you explain it I build on what you've already taught me and your solution is probably something I can replicate with what I have, at least partially.

When you do a video on opamp input offset current and show a test circuit on the bench I run off and build a similar circuit and run those tests myself. I spent about $2000 on an analog scope, function gen, power supply, multimeters, solder station, hot air reflow, anti static gear, books, leads and probes, prototyping bits and basic jellybean parts. It's a real lab now and I can build practical circuits. I'm still a software guy but I haven't built a single uC based project yet but I did build a PWM dimmer LED dimmer for my bench LED strip out of an LM317, 555 timer, and an N-channel mosfet which was my first ever electronics project and it works brilliantly (after 3 complete failures which you'll no doubt nod your head at) ;) I can't believe people get paid to do this stuff!

That's why I love your FF videos (as well as all the others and the Amp hour radio show too). They make a difference to people like me though I can't say how many others are out there like me.

If not many people watch them then please make them premium content. I'd pay $100 a year to access a library of FF videos, or like $8-10 each, no problem. I'd pay that for a textbook and not learn half as much.
