I was really looking forward to trying out binaural Morse Code when OZ1LAV Steffen said he could add it to his M5Stack Tab5 firmware for the QMX. I kept impatiently waiting until he added it, not realizing that there's no monitor audio over USB from the QMX to the Tab5. So you can listen, but you can't use it for an actual QSO, unless you have an audio switch triggered by the PTT on the QMX. One person mentioned having an antenna audio switch device that worked for this, but it's large and n…

Screenshot of KiCAD showing a routed circuit board without filled ground planes. It has a lot of busy text, but the components are relatively sparse. It has a coin cell holder at the lower right, an audio switch IC at the lower left, a space for a direct wire connection or a 3.5mm jack at the middle of the lower side, three such across the top, and various small components (resistors, capacitors, and ferrite beads) sprinkled around. Lots of tiny vias are sprinkled across the board in an attemp…
Exactly the same component as the previous picture, but with ground zones filled on top and bottom copper layers.
3D rendering of board with all the components installed except for the 3.5mm jacks. This is what it would look like before installing either the jacks or the wires for the three inputs and the output. Each input/output presents a separate decision for whether to wire directly or use a jack.

I need help understand why you put a datacenter in the desert where there is an abundance of heat and dearth of water.
That's about 4.5 million gallons a day, enough to supply about 45k households, in case you were wondering.

AI has come for Arizona’s water
Arizona has long courted big business, from tech to agriculture. Now the state is facing a water crisis. Are data centers the breaking point?

for those interested in such things, Arcaneum now has an install subcommand that will add a watcher to a directory and reindex any changed files once committed.
you can keep a markdown knowledge base up-to-date async behind the scenes

I'm re-reading Dune right now for a variety of reasons, and there's a lot wrong with it IMO (including serious queerphobia/misia & fatmisia), but it also has a ton of very cool ideas. Just came across this chapter-starter quote:
"The concept of progress acts as a protective mechanism to shield us from the terrors of the future."
This perfectly matches part of what I was trying to express with my recent short story about the pessimism of techno-optimism:
