 Just a quick note.  My partner and I went to see Robot Dreams with the 11 and 9 year olds about a week and a half ago. First, the movie is awesome! It stays almost true to the book in that there are very, very few words at all. More in the movie than there ever were in the book, but still. The whole thing was a lot of fun and I highly recommend it. The oldest kid wasn't there because she was attending summer camp up on the orthern edge of the penninsula.  After the movie, my partner and I went off to do errands in one direction, the 11 and 9 year old headed  towards the house on BART. And! Guess what? They ran into their older sib on the bus home. There routes coincidentally linked up for the last leg and they hopped on the sam bus she was on. About a stop later, they all realized it. Public transit and independent kids are pretty awesome! We got to do our errands. The kids got to go do what they wanted, and they ran into each othere anyway! Without transit, I doubt...

  A few weeks ago, the 13, 11, and 9 year-old gang and I were out on our yearly camping trip, hanging out near Great Basin National Park above Baker, NV, when KO6BTY and I got to participate in a Ham Radio Workbench episode! It was a lot of fun! (It was also one of the latest nights up we had during the trip.) If you're landing here from there, we talked about a lot of things including: Project TouCans ( page ) ( and in general ) POTA / SOTA How early versions of TouCans were inspired by the OHIS Camping KO6BTY and my writing projects regarding one Michael Gladych ( page ) ( general gladych ) ( general history of physics ) unschooling / homeschooling / parenting in general and we got to talk to Thomas K4SWL about qrp rigs We just made it back from our camping trip yesterday, so I hope to have a lot of updates over the next few days, and maybe some pretty pictures as well like this one of Mt. Wheeler and, of course, Project TouCans.

 On one of the most interesting radio days of our recent camping trip, Project TouCans made QSOs with Australia, Japan, Columbia, and Argentina, all on the same day! The QSOs to Japan and Australia were made in the middle of their night. The Japan, Australia, and Columbia QSOs were all made in a sixteen minute window beginning with VK3YV at 12:40 UTC. What was the Propagation Mode? While the QSOs were awesome! How did they happen? I did a bit of research.  Spoiler: I don't have an answer yet. If you have ideas, I'd love help on this, please comment! Dayside stations talking to nightside stations led me to sv1uy's page on chordal hop propagation which had a nice diagram The rest of the notes from below followed from this diagram. I don't have answers yet, but here are my notes. I've been talking with the kids about radio occultation, refraction, and of course, the Gladych research project during all of this. I'm also using it to introduce trig which will layer i...

 The gang and I made our first QSO with Australia this week! The QSO came bundled with two other DX contacts made with Project TouCans—all in a 16 minute window—which I'll write about soon. Our camping site is nestled below Anvil Mountain to the East and across the Million Dollar Highway from South Mineral Springs, about two miles north of Silverton, CO. We're surrounded by peaks on all sides. Bear Mountain peak is framed in my pictures of the rig. Project TouCans was probably 20 feet up in its dipole. This turned out to be difficult to show in photographs with the proper perspective. I finally decided to make a gif of different zoom levels of a single photo. The picture below starts out focused on Bear Mountain Peak and then zooms out to include the rig and the ground outside my partner's and my tent. You can see the Bluetooth transmitter that brings the head phone audio down to the ground hanging from the bottom of the rig. The campsite is gorgeous and almost completely b...
