Selecting an ESD Diode

Under specified datasheets and lack of understanding of ESD protection has made picking diodes a hit or miss scenario. This article will lay out a method to make your diode selection much more successful.

What is not covered:

  • Lightning strike protection
  • System level design

Choosing your ESD diode will require simultaneously solving the following four requirements:

Mortgage Estimates

I signed up for a seminar for those interested in purchasing their first home. I've seen my coworkers attempt a number of different strategies: buying a condo, buying a home and investing out of state. Let's see how those strategies stack up. Note: Income and expenses were estimated with a single individual making $100k/yr. I also used a pretty healthy down payment as most of my coworkers are a) in their 30s and b) have had ~10 years of professional work experience that includes stock options. This does not reflect my income or savings, which may be higher or lower.

Philosophy vs Technology

This is a huge subject I'm not about to take on completely, but I've had it on my mind for some time since seeing a documentary about the Logical Positivists and reading some of Husserl's work.

Obvious questions:


To the lay person, confidence is often defined as "believing in yourself". Beyond that definition most (including myself) cannot provide much more detail. Words like "esteem" or "capable" come to mind but if I were to ask myself what are the characteristics of confidence, how to measure them and how to acquire them if you do not have them I would be at a loss. Furthermore, the subjective experience must be considered as much as the objective. What is it like to be confident? To experience confidence?

Bits and Pieces for an Architechtonic

Jotting down some notes.

Metaphysics. Standard stuff. Objective description of the universe. Objects, reality, truth, epistemology and free will. Bridge to science. I consider this the "outside in" approach and it ended with Nietzsche during the Romantic period.

Beersworth Chart

How much are you really drinking? How much alcohol is in that 7oz pour of stout? Did you just hammer a bomber of IPA and want to know what you've gotten yourself into? Use this chart to find out.

1 beer = 12oz @ 5%

(And just for kicks a 16oz pour of Firestone-Walker Union Jack is also added.)

Love Language

At the behest of a friend I took the "Love Language" test. It is an attempt to score how one expresses love and (without awareness of such) how one expects to be loved (iow how they feel loved).

The results:

7 Words of Affirmation
10 Quality Time
1 Receiving Gifts
4 Acts of Service
8 Physical Touch

Each has a maximum score of 12 points.

Ontology of Ontologies

Over the years of my reading philosophy I've always kept a basic "epistemology of philosophical knowledge" in my head as a way to organize all knowledge. But several difficulties arise:

  1. Is it comprehensive, covering all philosophical knowledge?
  2. Does it cover all knowledge? If not does it provide hooks to provide or expose a way to organize all knowledge?
  3. Is it authoritative or just bull? I just made it up to track everything I've learned.
  4. Is it useful or functional?

Statistics in Engineering: Summary (Part 8 of 8)

This series is aimed at providing tools for an electrical engineer to gain confidence in the performance and reliability of their design. The focus is on applying statistical analysis to empirical results (i.e. measurements, data sets).

We've covered the basic methods of applying statistics to your design and verification environment. Now let's present them all together and discuss what method is most suited for a particular circumstance.
