Every year around Father’s Day, the US Forest Service organizes a fishing derby at a park in Trout Lake, WA. The creek that flows through the park is screened off and stocked with rainbow trout, after which the community is invited to catch and cook fish, participate in various kid-centric activities and learn about the forest service and fishing in general. This was an excellent opportunity for a family adventure and our second year attending this event. Unfortunately we were unable to arrive until most of the families had left the event. The forest service had closed their displays and the finger-painting tent and bouncy house had both been taken down. But this didn’t disappoint us since we were there to fish. We arrived at the creek and discovered that most of the fish still remained, along with the make-shift fishing poles constructed out of tree branches. We grabbed a fishing pole, baited our hook and made our first cast. I stood behind my daughter and patiently instructed her on how to strategically cast the line upstream, allowing the current to bring the worm to the fish. She was more focused on asserting her desire to hold the fishing-stick herself since she was a big girl. This continued until we hooked our first fish, but he got away. This cycle repeated a few more times until we landed our first trout. She immediately wanted to pick it up and hold it just before she asked when we were going to eat it. By the end of the day we caught our limit and I cleaned our catch while Siena jumped on our friend’s trampoline. The fish are currently in our freezer and I’m sure they’ll make a delicious dinner Sunday evening.
Fuss Nugget is my Co-Pilot
I haven’t yet taken my daughter flying with me and she keeps bugging me about it. My typical response is “when you’re older” which satisfies her for about 5 minutes. I recently thought about it and I’ve come to the conclusion that she is ready go to flying with her daddy. The Memorial Day weekend was a perfect opportunity to fly and the weather could not have been better. However, when I called the airport to schedule the Cessna, I learned that my airplane had been grounded due to a registration error. No flying today! Instead I used this as an opportunity to test my kid and she if she is ready for an airplane ride. The test consisted of the following checklist: [Read more…]
Viewing the Transit of Venus
Today a rare astronomical event took place: the orbit of the planet Venus placed it between the Earth and the sun. This event is called the Transit of Venus and it last occurred in 2004. It will occur again in 2117, so you can imagine my disappointment when I learned that the weather gods were not smiling upon us today. The Northwest experienced a weather system that brought rain and thick cloud cover completely obscuring the sun. The clear sky chart showed we might get a break later in the day and fortunately it was right! The clouds broke just after 5PM today and I seized upon the opportunity to drive to our local hardware store and purchase a piece of welders glass. Immediately after exiting the store I put the glass up to my eyes and I could clearly see the tiny dot of a silhouetted planet against the solar disc. I verbalized my excitement with a resounding “cool!” and drove back to work to show the rest of my coworkers and my wife when she finished her chemistry class. Astronomy is awesome!
Reflections on SEA-PAC: Attending My First HAM Radio Convention
I just returned from an awesome weekend in Seaside, Oregon where I attended the SEA-PAC convention, an annual gathering of amateur radio operators at the Seaside Convention Center.
First, a little back story: I’ve been a HAM for 9 years, call KG6PFU, but I’ve not yet been on the air. While attending Cal Poly I became involved with the Cal Poly Picosatellite Program, also known as PolySat. The aim of this program was to involve engineering students in an extracurricular project to design, build, and deploy an orbital satellite capable of remote sensing and downlinking telemetry on a HAM band. Because picosatellite communication involved using HAM radio frequencies, a number of the engineering students involved in the project took the FCC licensing examination and obtained our technician class licenses. Due to external commitments and schoolwork, I was only involved with PolySat for a short time and never had a chance to use my new privileges. Fast forward 9 years and I’m still a licensed HAM with a license that is about to expire, and I’ve still never been on the air. [Read more…]
Memorial Day
Most people think of today as just “a day off”. This particular day off, along with our freedom, was purchased with countless lives. To those who serve, and to those who have made the ultimate sacrifice to secure our freedoms:

Infrared Makes a Great Presentation Aid
After I finished speaking about engineering I brought out one of my company’s gyro-stabilized camera gimbals. This one, in particular, has both an optical and false-color FLIR Photon infrared camera. The gimbal is able to autonomously track objects while they move and while the gimbal itself is perturbed by wind and other disturbances. The students thought that was incredibly cool as I tracked their movements using the optical camera. Then I turned out the lights and switched to infrared mode. My audience lit up like a Christmas tree under infrared and I was greeted with a resounding “cool…!” I had one of the students put her hand against a wall for a few seconds and the camera picked up the hand-shaped residual heat signature. I also had one student walk around the room trying to escape the gimbal’s gaze. He was successful but not immediately!
I have given presentations about engineering and technology to grade-school and high school students in the past and I enjoy it every time. I think I made a few converts on this run!
