With so many different parts available, it can be hard to figure out which component to use. Taking a look at what others regularly use might make this process easier.

Another new page by [[russ_hensel]], not much more than a stub now.  Feel free to join in with your recommendations.

So many parts, so many variations, which to pick.  Why not try to see what is popular:

*[http://eeshop.unl.edu/storlist.html The Big List These are the parts the EE Shop keeps in stock to sell to students.] UNL likes them why not us?
 +
*[http://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/6-301Solid-State-CircuitsSpring2003/Tools/ This section contains circuit examples from commercial products and datasheets of transistors which are studied in this course. ] If MIT studdies them, maybe they are worth looking at.

*[http://www.edn.com/archives/1995/052595/11dfcov.htm Choosing an op amp: it's no longer a trying task] The oldies in particular may be good, but not expensive parts.

== Kits and Projects ==
If you're working from a kit or published project consider getting extras of the parts.  The authors of these things tend to know, and pick, what's popular.  If you use them once you may use them again; there are exceptions, though.

If you are working from a kit or a published project consider getting extras of the parts.  If you use them once you may use them again.  Also the authors of these things tend to know and pick what is popular.  Always think about; it there are parts that are exceptions that you would never use again.

==If you are working with X then Y where Y will help you find the popular parts==

Note that links may or may not be to the best source.  Look around, add a link if you find a better one.  Do not delete a link, unless product is gone for good.
  
== PICs ==

===X=PIC's===
Because PICs are mostly digital logic, if you use PICs you will need most of the stuff in the [[Popular Parts#X=Digital Logic]] section as well as stuff in this section.

Easy choice is LM7805.  A couple of caps usually go with it.  .1 and .01 bypass caps are generally useful.

|An op amp might be good for 20 mA.  Couple it to a darlington transistor and get a full ampere (1000 mA).  You may want to go push pull with a pair of npn and pnp transistors.  With this you can build power supplies, battery chargers, [[motor driver]]s, and audio amplifiers.

* 74HC595 -- for more output pins. SIPO eight bit shift register with output latch. Perfect for letting the propeller clock [[POV display]] slowly clock in the next value, then LOAD them all at once. Near the bottom of the page describing the [http://www.robotroom.com/Tach.html "Digital Numeric LED Displays Tachometer (RPMs), Temperature, and Counter"] project, David Cook says: "The 595 is a great 8-bit serial chip because data can be shifted in without affecting the existing output. All new data is then switched over at the same time. The 595 can also be daisy chained. In this case, 48 outputs are controlled with only three wires (data, clock, and latch)."
