I suggested to send one of the LoRa nodes flying with helium balloons. The Chinese developer didn't think that was such a good idea tho.
Had a good laugh at the thought of a fighter jet squadron buzzing by to shoot my colorful party balloons :)

Last minute Reddit Secret Santa gift for a dog owner: 3D printed flexible LED collar
Besides the LEDs there's also a battery and a charge controller embedded in the infill structure. I've just paused the print for 5 minutes and squeezed it all in. Then I've epoxied magnets on both ends so that they only fit together in the rig...

... when a thing has kilometers of wireless range and years of battery life, that might change?
My last question about this was purely based on a private message I got from a new patron. What a weird coincidence, that the day after that a rearrangement of Patreon, Inc. fees were announced. I absolutely didn't know about that.
The most important change I can see in wall of text is, that patrons will s...

I think general purpose cnc machines don't need encoder feedback, because step loss is almost always audible. But since I am still pursuing my ideal-machine-agenda, I think I'll use these hybrid stepper motors with built-in rotary encoders.

Since I still didn't manage to get a newer source measure unit I wanted to try and DIY one soon. With modern components I think it isn't nearly as difficult as older Keithley gear makes it look. Also µA sensitivity is absolutely sufficient for me, but once I get that working, I could look into nA and maybe even pA?
I think a ...

With pretty high speed too, as can be seen by the squiggly lines. Those are from vibrations after a fast deceleration.
And with almost no fine-tuning, as can be seen by the 'leftovers' in between some pads ...
Exciting stuff if I may say so ...
