WxMonitor Update
I made a major improvement to the WxMonitor User Interface. I increased the vertical slider resolution on the temperature, dew point, humidity, barometer and rainfall readouts, and
eliminated the need for oddball multipliers for the labels by using custom labels.
For example, my barometer scale used to run from 275 to 315, which meant that my legend had to say "0.1 in Hg". Now the
scale reads 27.5 to 31.5, so the scale now reads "Inches Hg". Internally, the slider runs from 2750 to 3150 instead of 275
to 315, so it has 10 times the resolution, and no rounding is necessary.
I made similar changes for all of the slider display controls. In conjunction with these changes, I also made the display
more configurable, so that it is easy to change the display from English to metric, etc.

WxService Update
Completed support for the TAI8570 Pressure Sensor. We now have barometer support! It is working extremely well.
The TAI8570 contains a pair of DS2406 dual addressable switches to clock data into and out of the Intersema MS5534A Barometer
Module serial interface. The task must send and receive every data bit as a separate MicroLan transaction. Both switches are
independent devices on the MicroLan.
This is a rather primitive interface to deal with, compared with, say a temperature module, which returns complete numerical
values in a single 1-Wire command.

Welcome!
This site is dedicated to my interest in engineering. I use it as a place to just put stuff "out there" for anyone who
might be interested, as well as a job search tool. This page contains my engineering web log (to your left). Anything that
seems timeless enough, or too involved for a log entry may get it's own page as a full-blown article. And, of course, my resume
is here for anyone who might be considering hiring me to do something. Email me.
About Me
I have worked as a broadcast engineer, electronics designer (analog and digital) and software developer. I especially
enjoy audio engineering, although I've been writing software for the last several years, since that's where the opportunities
are in the Pacific Northwest (this is Microsoft country after all). I'm currently working as a Senior Staff Engineer -- Resume at another large independent software vendor in Washington State.
I majored in mathematics and physics in college. Other interests include music appreciation (baroque, classical and early
romantic, ragtime, and 60's and 70's rock & roll), high fidelity audio electronics, meteorology and of course, computing
hardware and software. I tend to think a lot like this guy.
