And a nice link by @Crass_Oscillator to a reference for learning about Semiconductor Devices (from a thread about that subject):

This is a pretty comprehensive free textbook with an introduction to the physics assuming little background, as it is intended for electrical engineering students who usually have taken at most one quantum mechanics course (and that is still uncommon):

It's actually a pretty good book, aside from a few poorly written passages here and there, along with some typesetting problems.

Yes indeed; very useful. I just checked and found that I bookmarked this on 6-20-2011.

Nice link by @Windadct about "Magnetics in Switched-Mode Power Supplies" from OnSemi:

Stumbled upon this from OnSemi the other day... pretty comprehensive.

Nice pointer by new user @Bcavender to some low-cost (free for the limited version) FEA software "LISA", most likely written by a fellow HAM radio enthusiast:

A great example in the medium productivity software level space is LISA. It is a really nice basic FEA package that imports a variety of common 3D file formats for well above trivial level designs and costs $300. I am guessing that this venture is a one man show, but both the software and support are top shelf. It does 80% of what I find necessary for good/economic design and saves a great deal of wheel-reinvention on my part. From the verbose responses to support questions, you can tell the gent behind the package lives, breathes and loves practical, usable FEA. He appears to be having a ball.

I'm was trying to figure out what "free/affordable" meant from their website.
So the free version is limited to 1300 nodes, otherwise purchase.

A treasure trove of old magazines. Dating back to at least 1905.

Nice find, thanks for sharing, Tom. I especially like how they are careful about copyrights and author permissions on the documents.

Very nice Opamp Application Note via @jim hardy from a current thread on Opamp questions from newbies:

I notice AN31 is still around but it's now a TI document (TI bought National some years back).
The questions must have persisted because they now show power supply connections in their sample circuits.
Here's a link - have fun !

Agreed. Very useful circuit diagrams

Although I've never read much of the great analog designers of;
J. Williams, RA. Pease, Horowitz & Winfield and now Basso in SMPS design, I found my experiences common to what I have seen and learned a few things.

If you want to learn what isn't on LTspice schematics, you ought to find these books online or in Archive.org.

If you want a great source for reasonable volume parts from legitimate Asia suppliers and all distributors or just check for valid part numbers... and especially for hard to find volume stock and negotiate for price.

From a thread where the poster was looking for high dielectric withstand materials for building a large HV capacitor:

I suggest to use the MatWeb "Property Search" to check whether some other materials might match your requirements: http://www.matweb.com/search/PropertySearch.aspx
