Hello,

A resonable channel on youtube is from eevblog:

I also recommend this channel. Dave Jones is a very clever and knowledgeable bloke from Down Under.

 

Yep, Kangaroo Dave, Paul Carlson, Alan Wolke W2AEW, and the IMSAI guy are all very knowledgeable in their areas of expertise. And I am sure there are others there who are very knowledgeable as well but then there are a whole LOT of Bubbas there as well... You have to pick and choose wisely as with most things in life.

 

No love for ElectroBoom in here?

 

The circuit you posted is not a voltage regulator.

 

"Schematics for free" is my favorite schematic website, but search for that and several other popup as well.

 

As a youtuber myself, I can tell you the pressure to create content overrides everything.

Clicks and views become more important than logic, wisdom, or value.

There are a few great creators out there that really know what they are doing, but these are rare, so be extremely selective and skeptical.

I watched a lot of his videos when I started learning electronics. Turns out he is a Canadian engineer with a master's degree in EE.

Here is a new channel I found presented by a guy who has an associates degree in EET. He provides a nice visual and includes the math.

Ben Eater's channel is also really good but he failed first year college. Most of what he says is correct but some is not. As you probably can imagine, I put a lot of stock in one's formal education especially when they become educators themselves. Needless to say I do some digging into whoever is giving me advice.

If you haven't already, check out the textbook section of this website. It has many EE exercises. If you do them all, you'll come away with a solid background in electronics.

 

I also have a few links to circuit sites FWIW:
Basic Electronics Tutorials and Revision (electronics-tutorials.ws)
Circuit Digest - Electronics Engineering News, Latest Products, Articles and Projects
Electronic circuit projects in simple ways of learning (eleccircuit.com)
Circuit Finder - all electronic circuit diagrams in one place (circuit-finder.com)

But, I use Google first...

He is amusing and entertaining I'll give you that. In the same league as Photonicinduction.

So much of that kind of "fun" ends as boring and then, what do you actually did learn after the so many, shorts, jolts and shocks??

Wish videos were all in line with those by W2AEW.

 

Hello,

The videos of W2AEW are mainly RF related, but still very informative:

The circuit you posted is not a voltage regulator.

Actually . . . that is correct. Technically, it is a voltage attenuator. If the input DC has any ripple, transients, voltages surges or sags, all of that will appear, attenuated, at the output. The percentage of attenuation is adjustable with a low-power element (the pot) as opposed to a high-power element such as a power resistor, but the output voltage will be only as stable as the input voltage. This is a significant difference from what most people expect from a "voltage regulator" circuit.

Note that if the power involved is even 1/10th of the stated ratings, the transistor will inflame rapidly.

Well, i went through all those videos that are not about RF but transistors or op amps. Extra credit: I could understand every single word in all of them.

No he is great, helping me get a Google certificate at the moment.

 

You see what they want you to see. There are loads of fake/scam/misleading videos (e.g of 'free energy' devices) , but as a novice it may not be easy to distinguish them from genuinely helpful videos.
Just because a circuit is simple doesn't necessarily mean it is invalid or inefficient.

What do you mean free energy is totally a thing they're just hiding it from us.

Totally agree with you. Except I think it's not just formal education it's real world experience that is required to actually apply those skills that you learned and memorize them deeply.

His videos are there to inspire people in the field of electronics. I went to school for 6 years and haven't applied my knowledge and having him just have small videos are just quick refreshers where I know exactly where where this is going but it's still fun to watch.

 

When I see the posts from those who have built some of the circuits that don't work as claimed, it certainly damages the image of being a good source.

Having a clown to teach me? No, gracias.

You never had teachers that made you laugh. Wow you're schooling must have been very boring.
