Microwave work and Photography First Draft
8:38 am pst
I delivered the San Bernardino Microwave Society (SBMS) 3456MHz transverter board by Chris N9RIN et al to Kerry
Banke N6IZW for testing on 20 January 2009 at the San Diego Microwave Group meeting.
The meeting was great,
as usual, and there was some discussion about picking the right IF, and questions about using a transverter in the first place.
While not intended to be a final design, the reason we're investigating a transverter such as the SBMS project is to get
up off the ground and on the air. It may not work out due to the fact that the 2m IF may not support the 10MHz bandwidth that
we're aiming for. Even if it can support that wide of a bandwidth, the phase noise needs to be pretty good. I'm
interested in seeing the results. The test plan and results are updated here.
Photographically, I made my first attempt to create something along the lines of Jessica McClung's work that I saw at photo LA. Here it is:

Soccer, Trip Summary
6:44 pm pst
I am in the process of recovering from the adventure to Corona then Santa Monica, then back to San Diego.
The SBMS meeting was wonderful (as usual), and several really good conversations about MEP occurred.
LA was exhausting in a good way. It took 5.25 hours to walk through the entire place, and it bordered on overwhelming.
Initial impressions of the Photo LA are as follows. There was exactly one science oriented photo - an earth-moon-earth telemetry
bounce done by the signal corps from 1946. Several galleries had the same photos that they had two years ago. I recognized
an exhibit from San Diego Museum of Photographic Arts that I really liked, and still like. I found a new artist doing something
sort of like a collage, but not really, and I pored over her entire collection. I am inspired to try and incorporate this
style and produce at least two works. Her name is Patricia McClung. I was able to meet the photographer, and had a short and very enjoyable conversation with her. There was no obvious high-dynamic-range
work (we suspect that the hoity toity photo set has rejected obvious HDR as a fad), there was no macro work, there was
a lot of purposely blurry photos that we didn't like, there was much less overtly lurid and sexy work than two years ago,
and there was a whole lot of Ansel Adams prints for sale. The number of mixed media works was down from two years ago. It
seemed about as big and the prices about as high as two years ago. A photo I loved from two years ago - of the interior of
an amazing Chinese sock factory - was back, and still out of my price range. Lovely awesome photo of sewing and weaving and
cutting apparatus, with a single human face lost in the center somewhere, peering between the white and silver and gleaming
We had an excellent meal at Jinky's Cafe in Santa Monica - highly recommended.
Optimized Tomfoolery is going to do some self-portrait and cross-portrait
This morning was the first soccer game of the winter season. Our team won 4-0 and photography happened.
The field had a great background - trees and an embankment and shrubs instead of the usual parking lots and cars. The light
was great, the boys played hard, and the spectators cheered loudly. I used my new Stanley thermos
to bring along some coffee. Ah, the luxury.
After the game, we went to Fry's Electronics and got some necessities
- a replacement emergency radio (charges via hand crank), Lips for xBox, Gran Turismo 5 (with the Stig!), and Pyro audio editing
software. And some magazines.

SBMS Meeting, Photo LA, First Soccer Game
11:36 am pst
Heading up this afternoon to Corona, CA for the January 2009 San Bernardino Microwave Society
meeting. The topic tonight is compasses. This has relevance to MEP because we need ways to accurately point our antennas
once we know where the other station is located.
Friday afternoon is Photo LA
. We missed last year, and can't wait to go back and get all inspired. And, just in time, because the very first game
of the school soccer season is Saturday at 10:40am! We plan on doing digital and paper books for the team this season,
and already have some nice shots from practice.
Adding to the mix is an evaluation of the free GNU math software Octave
. It's supposed to be "mostly compaitble" with matlab. This may be our new baseline math software for MEP since
Mathcad is no longer supporting single users.

SBMS Transverter Test Plan
Began working on the SBMS transverter test plan today.

Webcam work, Observachapel, Post-vacation flurry
Our Christmas break is nearly over.
9:56 am pst
We're back to work on MEP with a transverter to characterize, work on
the webcams is proceeding, and another project, a combined astronomical observatory and chapel (Observachapel), will be added
to the website as the initial designs begin to accumulate. The site of the Observachapel will be on Palomar Mountain, CA,
and will have a robotic telescope accessible from the web.

Happy New Year! Working on the Webcams
Hello everyone! Happy New Year! I'm working on the webcams this evening, trying to get them working on delmarnorth.
