ARRL Field Day 2013 with W7RAG

As the sun sets the fun begins. Radio propagation is better at night.Since last year’s Field Day, I’ve upgraded my amateur radio license to General Class, but still haven’t spent any time on the air. Instead, I’ve been using my amateur radio privileges to down-link wireless video from remote control airplanes, so all is not lost. Field day is a great opportunity to get on the air and work the HF bands, making remote, long distance contacts from off-the-grid power and field conditions. Another great incentive for attending field day is conversing with other amateur radio operators (HAMs) about a variety of interesting and geeky topics. I end up learning a ton about amateur radio and other technical fields, so it’s always well worth the investment of time and sleep deprivation.

Immediately after arriving, I ran into another first person view (FPV) hobbyist who is also a HAM. He had a small quad copter with a wireless camera and we spent about an hour flying this little bird with down-linked video. Though it was small, it performed admirably in the wind. When the quadcopter’s battery finally died, he brought out his 20 meter mobile rig and used a slingshot with a fishing reel to string an antenna through an overhead treebranch. With so many amateurs competing in the field day contest, it wasn’t long before he made two contacts, one in Manitoba, Canada and another in Nevada. His entire mobile rig was easily transported in a hard briefcase and powered by a couple lithium polymer batteries, originally intended for powering remote control aircraft. I can definitely see myself with a similar rig, making contacts while camping on a remote mountain top.

As the sun set, we got down to business: eating junk food and talking about technical stuff. While there was a radio contest going on, we were too engrossed in our conversation about robotics, Linux, nanotechnology, processor design, etc. that we let hours pass before we finally sat down at the stations to begin DXing. I lasted until about 5AM after which my fatigue level left me mostly zombified. Every time I’m determined to pull an all-nighter with ease (like I did many times in college), I’m left disappointed and exhausted. I must be getting old! :(

Hopefully by this time next year I will have purchased my first HF radio and made some non-field day DX contacts. Time will tell.

Maternity Photos Take Two

Lost Lake Maternity PhotosOur new baby gave us an opportunity to take a new round of maternity photos, this time in the great outdoors. We headed up toward Lost Lake, stopping at a cherry orchard along the way. My wife had a few ideas for  poses that she found on Pinterest that  made use of the older sibling in the photo shoot. While Siena did cooperate for most of the photos, we had to bribe her with candy at least once. After the cherry orchard, we made our way up to Lost Lake, past the “road closed” sign and encountered a “resident” about 100 feet from the parking area by the lake. We were politely asked to “leave the premises” due to the imminent dangers posed by the ongoing snowplowing efforts. I scratched my head looking for imposing snow drifts and hazardous black ice, only to find bare roads and parked plows. Still, we complied with the request and returned a few days later. Our return trip offered us a chance to stop at the orchard again, with a different outfit . Our trip to the Lost Lake was successful this time as we parked and made our way to the shore. It was a gorgeous day and the calm wind almost made for a perfect refection of Mount Hood in the lake.

Return to the Trout Lake Fish Education Day

Siena and Daddy start fishingToday my family and I returned to Trout Lake for the annual fishing derby and fish education day. Unlike last year, we arrived on time and came prepared with an eager 4-year-old and appropriate fishing gear. The trout were plentiful and Siena caught her limit of four fish. We are all looking forward to dinner tonight when I prepare fresh trout sauteed in garlic butter and olive oil.

Last year, Siena  required a great deal of supervision and encouragement. This year she was engaged, patient and successfully landed two fish by herself. The other two required my assistance, but we got the job done nonetheless.  After we were satisfied with our successful fishing expedition, we took Siena to a nearby playground where I excitedly called my dad to share my daughter’s accomplishment. He quickly reminded me of our Tahoe Trout Farm trip when I was 8 years old, asking if Siena caught any “flying fish”. To this day, he still enjoys teasing me about the hasty and haphazard manner in which I landed my trout. While my father expected me to “play the fish” as a prerequisite for thorough enjoyment of trout fishing, I fortunately had no expectation for Siena. In fact, I believe the two trout I helped my daughter catch today could easily be described as “flying fish”.

Hiking the Horsetail Falls trail to Oneonta Gorge

Horsetail Falls (I can't choose which angle I like more)Horsetail FallsThis year for my wife’s birthday, we hiked the Horsetail Falls trail to Oneonta Creek. We started late in the day, which  limited our hiking time, but simultaneously provided gorgeous light for late afternoon photography. In fact, the Horsetail Falls Trail, when hiked its full length, passes by Middle Oneonta Falls and Triple Falls. I’m looking forward to returning in late Autumn to shoot Triple Falls accented by yellowing Bigleaf maples.

The trailhead is located fifty feet or so east of Horsetail Falls. This waterfall is adjacent to a parking lot, making it a popular destination for tourists passing though the Columbia River Gorge. After photographing the falls, we were warmly greeted by a steep switchback and a decent elevation gain as we started our hike. The switchback ended at a connecting trail about 2/10 of a mile from Ponytail falls. The trail followed a cliff that offered amazing vistas of the Columbia Gorge 500 feet below. The lush foliage began to transluce as the sun set, casting long shadows and bathing the Gorge in golden light. Here delicate wildflowers clung to their precarious perch overhanging the windswept basalt cliffs.

Our daughter was sitting this hike out, spending time with a babysitter she adores. Gabriel, on the other hand, was very content on this, his first outdoor adventure. He fussed a bit as we neared Ponytail falls, quieting down as Momma fed him. I used this downtime to photograph the wildflowers and river vistas that the elevated trail provided. A lone monument to a 14 year old hiker who perished in 1988 from a fall can be found here. Every year recreation in the Gorge leads to deaths or injuries, so it is important to be well prepared when venturing into the wilderness and to be aware of the potential danger obscured by the alluring natural beauty.

Ponytail Falls is a hidden gem. Erosion created a pocket behind the falls that provides a very unique perspective. The trail curves around the bowl and behind the cascade itself, leading through an echo chamber that makes conversation difficult without a raised voice. The green moss and cold spray make this spot a relaxing refuge on a warm spring day.
The photo seems peaceful but the cascade made plenty of noise

We followed the trail past Ponytail Falls until it started to lead west, high above Oneonta Gorge, a narrow slot canyon that makes for a memorable hike. We paused at the top of Lower Oneonta Falls, though it was completely obscured by the heavy fern canopy. At this point, with the sun setting, we decided to turn back, saving Triple Falls for another day. We ended our day at Pfriem Brewery and sampled their brews while reflecting on the hike.

Rest in Peace Mater

We are standing in Japanese Garden that we landscaped together. This photo was taken in 2001.

I recently returned from a quick trip to Fort Morgan, Colorado for the funeral Mass and burial of my grandmother. She was 94 years old when she passed away. Gabriel and Siena joined my wife and I for the trip. Gabriel was a fantastic little traveler, making the trip at 5 weeks old, the same age Siena was when we attended my uncle’s burial here in 2008.

Though my grandmother lived in Fort Morgan for many years, she moved to California in the early 1990s, so I had the benefit of growing up with her nearby. One of my fondest memories was our joint effort planning and planting the Japanese garden and koi pond at my parents’ house. I had previously built the pond and waterfalls with my father but I greatly benefited from her gardening experience and critical eye when landscaping the garden.

Gabriel Has Arrived!

Gabriel BirthGabriel Connor was born Saturday April 27th at 1:35 PM. He weighed 7 pounds, 11 ounces and measured 20″ long. He came 3 weeks before my daughter and two weeks before his due date, so its obvious he was quite impatient and wanted out!

Theresa started labor at 11PM Friday night. Surprisingly, less than a half hour after labor began, her contractions were happening periodically at 5 minutes, lasting 45 second each. This is the frequency/duration criteria for heading to the hospital. Her labor lasted a total of 14 hours which was roughly half the time of Siena, though the labor was more intense.

Since our last visit, the hospital has been remodeled with a new family birthing center. The new rooms are spacious with a built-in Jacuzzi tub for labor. The postpartum rooms are also roomier and have an amazing view of the Columbia River Gorge and Mt. Adams. We’ll be bringing our son home tomorrow since he’s healthy and Mamma is recovering beautifully.

Florida and The Everglades from 35,000 Feet

Lakes and Palm TreesI recently returned from a week-long business trip to Florida where I spent my days learning a real-time kernel for use in embedded systems. I’ve been to Florida once before and I thought it was a festering cesspit then. Not surprisingly, my opinion hasn’t changed. The geography, climate, population, aggressive drivers and prevailing attitude of the locals basically amounts to a resounding “epic fail.” Fortunately, the company that hosted me was top notch, staffed with polite and very intelligent people. By the end of the week I felt fully versed in this new software component. Because of this, and because I wasn’t consumed by a killer sinkhole, I can safely say the trip was successful.

Due to my training schedule and jet lag-induced fatigue, I didn’t get a chance to visit the Everglades. Fortunately, I had a window seat for the flight home so I was able to survey and shoot the massive swamp from the airplane. Once I was done taking photos, I was able to sit back, relax, and take advantage of in-flight WiFi to browse the NTSB’s aviation accident database, starting with ValuJet Flight 592.

FIRST Robotics Competition – 2013 Portland Regional – Team 3711

Our team, The Iron Mustangs (#3711), competed in the Portland Regional for the last two years and returned champions. This year we came in third. Given that this is also our third year participating in FIRST, I’d say that we’ve had a good run so far. In fact, the season isn’t over yet. We are still planning to compete in the Ellensburg Regional starting on 20 March 2013.

Ultimate Ascent

The organizers of the FIRST Robotics Competition (FRC) decided to a throw a curve ball this year. All FRC games involve an autonomous period, followed by a tele-op (remote control) period. The end of the tele-op period requires that the students [Read more…]

FRC Team 3711 Robot Autonomous Demo for 2013

I just got home after another busy weekend of working on our robot in preparation for Ultimate Ascent, this year’s challenge. This was the final weekend of the 2013 build season for the FIRST Robotics Competition and I am convinced we’ll be fielding a great competitor this year. The video below shows off our autonomous mode, fully tweaked and dialed in. After I filmed the video I learned that we do have two additional days left before we’re required to crate up the robot. This is fortunate since we still have to finish the climbing mechanism and fine tune a few unpolished bits of code.

FRC Team 3711 Disc Launcher Demo

Whew, what a weekend of progress on our FRC robot! I think between myself and my student, we put in about 30 hours over the last two days. As of right now, we’re caught up with programming everything on the robot, but we still need to add code to drive the lift mechanism when it gets bolted on in a few days. This year we’re using C++ for programming so the entire process is much easier now compared with Labview. I shot a video at the end of the day to demo what we’ve accomplished:
