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 agree with every word of it.
Science is endangered by the demand for speed and by AI slop.

Trump selling out Ukraine for diesel sure is an indication that he's in a panic about the midterms.
What a coin-operated president. But that's not news.

@… What kind of microphone are you using? Built-in microphones on laptops usually are pretty bad.

It is a surreal moment when you watch Claude help research your city’s history by going through online archives of your local newspaper by painstakingly looking at screenshots. I am having flashbacks to microfiche research in High School and College.

Lite av en nishad grej det här men den här pseudovetenskapen är väldigt stor bland keto och carnivor-gänget.
Där är också ett hyfsat överlapp med det här och Kennedy/Trumps MAHA rörelse.
En grupp som i sin tur verkligen inspirerar svenska influensers med tiotusentals, ibland hundratusentals följare.
Keto-CTA studien och fuffens med statistiken

Keto-CTA studien och fuffens med statistiken
Du som följt mig över tid vet att lågkolhydratkoströrelsen är en otroligt konspiratorisk och pseudovetenskaplig rörelse som genom åren har spridit mycket felaktig information kring det mesta som berör träning, kost och hälsa. Som exempel kan du se hur de konsekvent och över många år medvetet väljer att misrepresentera och ljuga kring forskning på 50-70 […]

TIL that for years, #KiCAD has had the ability to hide GND from the ratsnest, by going to Appearance − Nets and clicking the eye next to GND. Maybe this was available over a dozen years ago when I first used it and I never knew, or maybe it was added some time in between. I design circuit boards so infrequently that I kind of have to re-learn KiCAD each time I use it. But this time I had e…
