An Ongoing Collection of References You May Find Useful

refThis is going to be a different kind of article - this is going to be a collection of links to reference materials, blogs and other information I have found useful and tend to recommend to others.  It will be an evolving article as I find various useful things, or you tell me about things you have found.  As much as possible, I will link to original sources, but if links for a particular reference are always changing, I'll save a local copy here.

check back, especially if you don't see anything interesting at the moment, that should change.  I'll try to keep things grouped in a logical way to me - I hope my organization will make sense to you.  I'm posting things randomly as I think of them or find them, so please don't think the focus today will be the overall focus of this article.

Analog References and Guidelines

All sorts of analog information from a variety of sources.

 

an31Application Note 20 An Applications Guide for Op Amps 

Linear Semiconductor, 1969

AN-20 An Applications Guide for Op Amps - pdf

 

The 25 page pdf explains basic op app circuits, provides equations and circuits for many applications.  Another oldie, this application note provides essential knowledge for using op amps.  The fundamentals never go out of date.

 

 

an31Application Note 31: Op Amp Circuit Collection

Linear Semiconductor, 2002

AN31 - Op Amp Circuit Collection - pdf

An oldie but a goodie from the infamous Bob Pease, this is a great guide to brush up on basic circuits and to find solutions to unique challenges.  I originally came across this in a Linear Application Notes book from Radio Shack years ago.

 

 

pocket refAnalog Engineer’s Pocket Reference

Texas Instruments, Art Kay and Tim Green, Editors, 4th Edition, Rev B

Analog Engineer’s Pocket Reference - pdf

 

An awesome collection of reference material, the 100 page pdf includes:

 Key constants and conversions

  • Key constants and conversions
  • Discrete components
  • AC and DC analog equations
  • Op amp basic configurations
  • OP amp bandwidth and stability
  • Overview of sensors
  • PCB trace R, L, C 
  • Wire L, R, C
  • Binary, hex and decimal formats
  • A/D and D/A conversions

From metric conversions and resistor color codes to analog design equations, this will be a useful reference.

 

Printed Circuit Boards and Manufacturing Guidelines

Whether you're laying out a circuit board for yourself or to go into production, the following articles will help you make a great board the first time. 

 

PCB Design and Layout Tutorial

 PCB Design and Layout Tutorial

David Jones

An excellent PCB layout tutorial by David Jones, of YouTube EEVBlog fame.  This clear and concise 25 page pdf starts at the beginning with terminology and goes to the end with a review of the PCB manufacturing process. Good practical advice for layout out circuit boards.  It's not geared to any particular layout program so it will be useful no matter what tools you use.

The link to the pdf is towards the bottom of the linked page.

 

 

 

PCB Design For Manufacture, V1.1Seeed Studios DFM

Seeed Studios

PCB DFM V1.1 - pdf

This is a 43 page publication by Seeed Studios covering best practices of PCB layout.  General layout guidelines are discussed; some of the recommendations are geared to Seeed's capabilities, but all of the Chinese fab houses will have simialr abilities.  It's a good overall review and also a good reference for specific issues.

 

bunnies blog

Bunnie's blog covers a wide range of interesting topics.  Check it out.  Following are a series of 4 blog entries, described by bunnie:

This month, I will be teaching a few MIT Media Lab graduate students and doing a bit of a “geek tour” of Shenzhen – we will visit several factories and live among the electronic markets to facilitate new directions and expand horizons in the students’ hardware-oriented research projects.

As part of the course, they will learn how to scale up their research utilizing the China manufacturing ecosystem. These lessons may also be useful for Makers looking to bootstrap a product in moderate volumes (hundreds to thousands of units). I will share some tips and insights from the course in four posts over the next month covering:

Getting a quotation: documentation standards (how to make a BOM)

Process optimization: design for manufacturing and test jigs

Industrial design for startups: guerrilla engineering on a shoestring budget

How to pick a factory: building and maintaining partnerships

 

Most of us will never enter large scale production of anything we build, but the cost is cheap enough that even if you only want a few copies of a board with a pain-in-butt tiny SMT part, assembly overseas can make sense.

 

If you ever have the opportunity to go to Shenzeng, you'll want a copy of bunnie's book, The Essential Guide to Electronics in Shenzhen.  It will help you navigate the unbelieve electronics markets and get over the language barrier.  It's got charts, tables and pictures so you can negotiate for what you want by simply pointing.

 

 

Electronics Tools, Calculators and Reference Info

Tools, calculators and reference collections from various sources.

 

eewebEEWeb Tool and Reference Page

EEWeb Website

EEWeb has an extensive collection of reference information, calculators for various parameters and other design information.  If you need to calculate the current-carrying capacity of a PCB trace or pick a standard value resistor or calculate RF parameters, this is the place to look.  Click the [TOOLS] button on the menu bar at the top of the page for the tools menu.

 

 

 wifi copyESP8266 References

ESP8266 chips are powerful microcontrollers with built-in WiFi support.  They come in many different form factors with different features and may be used as just a UART - WiFi interface or as a stand-alone microcontroller.  Many commerial products are based on this chip.

 

A Beginner's Guide to the ESP8266

Pieter P, 08-03-2017 

A Beginner's Guide to the ESP8266

This is a good introduction and starting point for learning about the ESP8266 and learning how to program it.  The Arduino IDE is used for examples in this publication - additions to the IDE seamlessly add ESP8266 devices.

Miscellaneous Stuff I Like or Find Useful

Big Clive's YouTube Channel

Big Clive's YouTube Channel

Big Clive, from the Isle of Mann, is always entertaining, humorous and educational.  Clive does many teardown videos of broken, dangerous or just interesting stuff, and usually doodles down the schematic to explain how things work.  If you haven't seen any of his videos, take a look.  Watch for the vice of knowledge and the xray machine that looks suspeciously like a hammer.  Here's a nice parody for your enjoyment.

 

Dave Jone's EEVBlog YouTube Channel

EEVBlog

Many of you probably know about the EEVBlog YouTube Channel - it's a wealth of excellent technical videos, teardowns, rants & raves and other great stuff.  Dave delights in exposing phony Kickstarter and Indigago champainges and provides thurough analysis of why some of these ideas are impossible.

 

ElectrodroidElectroDroid Pro

ElectroDroid Pro - Goggle Play Store

A wealth of electronics knowledge at your finger tips, including connector pinouts, resistor code codes and standard values and all kinds of specialty calculators, all well-organized and instantly available.  An extremely handy calculator is for resistance ratios, which are often needed for setting parameters on ICs.  The calculator will find a close match with 2 standard-value resistors, but if you add a third in either series or parallel, the calculator will provide an exact match to the desired ratio.  If you've ever tried to do this manually, the $4 cost of the pro version is well justified.  Sorry iPhone users - this isn't for you.

 

 

 

 

 

IrfranviewIrfanview Graphics Editor

Irfanview Graphics Editor

Powerful, free graphics editor and converter.  The program will handle many file types and convert between formats.  An extremely useful tool for editing, cropping, resizing and otherwise manipulating graphics files.  Believe me, it's gotten a workout in this article and virtually everything I post.

That deserves a Neo "whoa" !!! I have not read through it but certainly put it in my One Note for reference! Thank you sir!! I am definitely going to be giving it frequent use, and curious as to how many hits it is going to get here. WOW!

Glad you asked! I have to read your whole reference first. I have a collection of little things that are mostly IoT related, a bunch of C++ stuff, Java Script, jQuery, NTP, Linux, Powershell. Boards like RPI's, Blue Pills, ESP8266, ESP32, BeagleBone, ODroid, ATMEGA328P Nano clones, Rigol LXI, etc. etc.

Great! Let me know. I may have to build an index to sections.
