    Today I released version 0.7 of my print-in place single-paddle Morse code key.This will function as release notes:The most important practical change is that the slot in the lever for the stabilizer bar is taller, so that it doesn't bind. Previously, it sometimes bound depending on luck, and when it didn't bind, needed to be greased with a light lubricant.The most important user-facing change is updated build instructions, now with pictures. Previously, the instructions were just text.The most important developer-facing change is that it was rebuilt with FreeCAD 1.1RC, and all recalculation errors and warnings were removed. previously, it had quit building correctly due to changes in FreeCAD.The side contacts are better aligned with the common/ground screw in the lever when using thin ring terminals. (It was previously optimized for thick terminals.)The rear stabilizing bar was never necessary and was just extra weight and ugly complexity, so it has been removed.The spring radius is no longer an explicit parameter.I added more links to sources for hardware.This is getting close to what I would consider a polished, 1.0 release.As always, I crave feedback. If you build this, I want to hear what went well and what, if anything did not.#MorseCode #HamRadio

    Today's #HamRadio #POTA (Parks On The Air) adventure. Absolutely gorgeous, couldn't-be-better fall weather on a Saturday, so that it was a little surprising that we found parking space and that all the picnic tables were empty. Used my spiderbeam push-up mast to hold my inverted-v linked dipole up, tied the ends out to some trees, and got on the air on 20 meters, using CW (morse code) as usual. I first hunted operators in other parks and got 4 QSOs, but the pileups were deep, so I found a quiet frequency and called CQ. I didn't have to wait for responses, either! Some pileups were so deep they sounded like modem noise (showing my age here). A little intimidating for the new CW operator, but the other operators were patient with me.AZ is one of the states I haven't gotten in my hunter logs yet, so I was happy to see AZ pop up for one call sign. However, that operator reported IL, so I still don't have AZ. I'll have to keep hunting!By the end, I was getting a lot of QRM (interference from human sources). That's the curse of operating QRP (low power) — I'm sure they couldn't hear my measly 5W and weren't intentionally operating on top of me. That was OK, though; I had 31 QSOs and I was ready to QRT (quit) for the day.

    I've had an uncharacteristically productive morning.

    In order to 3d print a little amplified speaker box to use for #HamRadio SSB 2-operator POTA with my wife, I want to model components and then model the box to go around them.

    In order to 3d print a little amplified speaker box to use for #HamRadio SSB 2-operator POTA with my wife, I want to model components and then model the box to go around them. I found a speaker on grabcad that is only a few mm different from the speaker I found in my bin. Just different enough that I need to start over to create a good basis for my box model. I didn't bother constraining everything perfectly when modeling the steps in the metal shell, and I didn't model the cone accurately because those really don't matter that much. It's good enough to check for interference.I have barrel and XT60 power connectors already modeled from my last project to choose from here, but I need to add models for the 3.5" phono jacks and the TDA2050 amplifier board I bought from Amazon. Trying to decide whether to use that completely as-is or desolder the potentiometer for the volume control and use wires to re-route it to a more convenient place. A model might help answer that question.Not quite #FreeCADFriday unless you give me about 22 hours of grace. 😀
