Hi all,
I'm trying to see if I can get some of the Girl Scouts to also show up.
Kaleidoscope will be held the last weekend of April, and I'm hoping to
get some of the Girl Scouts involved. My expectation is we will meet at
Cody's afterwards for a late lunch and more ARDF conversations.
Lake Los Carneros Park in Goleta, CA will be the site of southern
California's next international-style on-foot foxhunting session on
Saturday, February 9. A ham radio license and knowledge of radio
equipment are not required. Experts will be on hand to teach you the
basic techniques of on-foot radio direction-finding (RDF). Bring the
kids and grandkids, then go out on the course with them!
There is no charge for participation. If you have receivers, scanners,
directional antennas, attenuators, or other equipment suitable for
on-foot RDF, be sure to bring it. Make sure all batteries are fresh. A
limited amount of RDF gear will be available for loan to beginners.
Besides some easy two-meter fox transmitters to help you learn and test
your equipment, there will be a beginner-level international-rules
course on the two-meter band, designed by Marvin Johnston KE6HTS. One
or more optional 80-meter fox transmitters may also be on the air. The
site area is slightly less than 140 acres. It is relatively flat,
making it a good site for foxtailers of all skill levels. If you need
some one-on-one help to get started at finding transmitters, just ask.
Full-color orienteering maps will be available.
For those who want to build RDF gear for use with their own two-meter
hand-held radios or scanners, Marvin will have kits for measuring-tape
yagis and active attenuators. Also available is an assembled and tested
assembly that includes the power switch, BNC connector, housing and
battery, ready to install as the tape measure beam is built. There will
be tools and soldering stations for building. If you're not an
electronic technician, don't worry because there will be experts to help
you.
If you want to build an antenna/attenuator kit, you must register in
advance.& nbsp; Send e-mail to Marvin (marvin(a)west.net) to pre-register
and get more information about equipment. If you already have equipment
and just want to hunt transmitters, you don't need to pre-register.
If it takes place, the building session will start at 9:00 AM. Please
be prompt. Transmitter hunting will begin about 10:00 AM. You may
start out on the courses at any time until 12 noon. Courses close at 2
PM. For those interested, we will meet at a local restaurant after all
the transmitters have been picked up for further discussion of ARDF.
Directions to Lake Los Carneros: From US 101 about 8 miles west of
downtown Santa Barbara, take the Los Carneros Road exit, head north
about 1/4 mile and turn right into the Stow House parking lot. There
should be plenty of free parking. Look for the orange-and-white
orienteering flag. The hunt start will probably be in the parking lot.
If that is too crowded, we will move to a nearby picnic area.
Ham radio talk-in is on the WB6OBB repeater, 147.000(+) PL 131.8. If
heavy rain is forecasted, check this site on February 8 for possible
cancellation.

The SBARC Camera at Diablo Peak on Santa Cruz Island captured a good
picture of Santa Barbara Island today. On the right is Sutil Island. The
distance from Diablo is about 60 miles.
Hi all,
Based on Brian's presentation at the last meeting, I thought I'd share the materials from the course I used to teach at UCSB ("MAT 594O: Sensors and Interfaces for Media Art").
UCSB MAT 594O Course materials
Course presentation slides (6-per-page)

Large ZIP files for readings and code examples

Distinctions between all these new small computers:
Arduino & many relatives - Based on common Atmel (CISC) microcontrollers found in many home appliances and industrial applications; CPU includes RAM, ROM, DAC/ADC and a selection of analog and digital I/O pins; can be programmed in a simplified C where one writes a set-up function and a loop function; development tools run on desktop environments. Boards have a standardized layout of I/O p;ins, ;leading to a plethora of daughter cards ("shields") for special-purpose I/O, co-processing, etc.
IOT (Internet-of-Things) Controllers (Particle Photon et al) - very minimal & low-power systems based on ARM (RISC) processors (more powerful than the Atmels); focus on stand-alone or embedded systems with WiFi or cellular connectivity; web-based development tools; also support daughter cards.
Raspberry Pi - Based on ARM RISC processors and cellphone motherboards; much more powerful and complex, native HDMI graphics, Ethernet, etc.; native Linux ports and (C++, Python, etc.) development tools; also support daughter cards, though these are much higher-power (e.g., 16-channel audio I/O).
Questions welcome!
