For my #HamRadio tunable elevated radial project, I want to isolate them from the earth and the mast, and I'm not finding an isolating mount that goes into a normal ½" "light stand". So I've come up with this design to build. (Yay, I can't just buy it, so I have an excuse to spend some shop time!)
From 1" 6061 aluminum stock and 1" POM:

  • An aluminum stem/spigot that fits…

Avatar 3 is showing in high frame rate or 3D or 3D with high frame rate. I haven't been paying close attention, but the last time I saw HFR was for The Hobbit (and to me it looked odd).
So is HFR back now? Or is it just for James Cameron's big budget?

I'm finally trying printing with Spiderflex (77-82A shore) filament. The print speeds remind me of my first 3d printer. Two tiny parts totaling under 3g took about an hour, printing with a maximum speed of 10mm/s. But having really flexible TPE is really handy; there's really no reasonable alternative!
Now I have new feet for my KX3, and honestly they might be better than the originals (sorry Elecraft!) They are at least as grippy on the table surface, and they are a closer fit on the …

Nad Sycylię i Kalabrie idzie mega ulewa i powodzie, większe niż to co widzieliśmy 1,5 roku temu w Walencji. Musimy poszukać sensownego miejsca na przeczekanie, zapełnić zbiorniki, zatankować, kupić wodę pitną i jedzenie na ładnych parę dni, bo może być problem.

Oczywiście nigdzie ostrzeżeń ani alertów jeszcze nie widzieliśmy. Pewnie powiadomią po fakcie.

I bought a pair of 25' Intellitron stainless steel whip antennas from GigaParts while they were on sale ("two is one and one is none" and the second one tipped me me into "free shipping" making its marginal cost pretty low). On removing them from the packages, however, loose roll pins fell out, and the bases fell off the antennas. Both of them.
A roll pin is an inappropriate fastener to use to connect two concentric thin-walled tubes, so this is a design failure. And the roll pins are …

A view into the bottom end of a whip antenna, showing yellow metal tabs for better electrical connections between the concentric sleeves, stops preventing collapsing the antenna too far, and a set of holes. An out-of-focus roll pin is in the background.
close-up view of roll pin. Only one end is tapered, and the pin is not straight.
External view of base sleeve that fell off the whip. It has flat sides where the holes for the roll pin go, and is tapered from the base where a 3/8-24 threaded stud is visible towards the open end at the lower left.
