Very cool! I have been interested in using UWB in a project but have yet to
see it in any tinkerer friendly boards. Although a quick search on tindie I
found this… which is kinda what I would need to begin to play around with
it.

Has anyone used UWB in any projects? What have you discovered?

Happy New Year!

-Brian

 From the article:

    Imagine:
       + Your thermostat adjusting the temperature automatically as you
         enter the room.
       + Your TV resuming your favorite show that you were watching
         yesterday as you sit on the couch
       + Your car door automatically opening when approach [sic] the
         vehicle and adjusting its seat position and temperature based
         on your preferences

None of those need depend on cloud services at all.  I'd argue that two 
of them (1 and 3) should absolutely *not* involve cloud services, 
because the providers will *never ever* get security right (because 
security isn't profitable), nor can they be trusted to not shut down 
their services and/or remotely brick your devices (we have already seen 
examples of all of these problems).

You IoT kids get off my lawn!  :-)

On Monday the mtg will be in person and also online with Jitsi here:

https://meet.jit.si/TriEmbed

Dawn and I are trying to get into a rhythm of predictable hybrid meetings so 1) there is an archive and 2) folks can attend in person or online. We have a decent conference mike/speaker now so remote attendees can reliably hear folks in the room and visa versa. And thanks to Forge folks' help we can leverage the big monitor and it's camera so the video can be highly effective too.

Pete,

If you listened to the video of our last meeting, you would have noticed
that there were some audio issues.
These issues could be mitigated if we all got a bit closer together, which
would also put us all in the view of a single camera.
As such, maybe try to move the tables and seats around to help with this
issue.

Let's agree to not ignore faulty sound but instead flag it right away. The conference mike needs to be as close as possible: a better arrangement of chairs was called for. The problem last month was the monitor remote was missing and it took a long time to get things sorted out and we were left with too little testing/confirmation.

The smaller room with a door is now available for meeting. We can put a
better monitor in there. If it’s big enough.

Negotiating on the double size space at the end of the same building - if
we can swing that, hoping a bigger room will be available to you for your
February meeting.

I just bought (a couple years ago) a TI-84 CE w Python.
I likely will never need anything more than a science calc on a smart
phone anymore
but it makes me happy just to have it nearby. Of course, anything at home
I'll use desktop apps.

BTW, I have an older TI-84 that won't boot (won't hold a charge?)
If anyone thinks they can instruct me to do simple EE poking. I'd be
grateful
I think it's internal lithium battery didn't get recharged for too long (?)

I Bought a TI calculator in college from the bookstore, after reading the
manual I realized it did not even have a clock.
Took it back and got the HP48, which was awesome for the time especially
for rectangular to polar conversions.  The reverse polish notation also
made so much more sense. Used the HP48 for about a decade, now for most
stuff I leave octave open on the computer and do any math I need in
octave.
Octave is great for my uses as it has printf() which works like C, as such
I can do numeric (hex) conversions using printf.
I suspect that AI will eventually replace my use of octave, specifically, I
can ask AI to write a python program for math and run it. I already do this
for generating graphs and graphics.

The feature I really loved was arithmetic in alternate radices, although it came too late to help with octal. When I was writing/debugging assembler and the tools were crummy it was heaven to have a hex calculator because screwing up with hand calculation would send me into the deeper weeds.

For some reason this reminds me of a source level debugger we used in the 80s called CDB (created by one of the compiler vendors). It had a "came from" command. It didn't do anything: it was just a joke. But each new dev that discovered it would spend minutes rolling on the floor laughing. ;-)

I am going to bring some YBCO superconducting wafers, liquid nitrogen, and,
with some luck, float a magnet, just above the surface (called pinning). So
if you are allergic to magnets, be forewarned.

I should have included the discussion.
Here is the link to the Hacker News piece. Clicking the article label (i.e. "SparkFun Officially Dropping AdaFruit due to CoC Violation") goes to the HN posting that I sent earlier. The remainder is discussion. Discussion on HN varies wildly in quality, with big dollops of idiocy, so keep the salt handy.

Subject: [TriEmbed] TL;DR Adafruit - Teensy && ~Sparkfun
Message-ID: <0e2d47f3-f452-4106-8946-25d93d9807e2@soper.us>

Sparkfun is now the exclusive distributor of Teensy (highly sophisticated Arduino compatible boards and accessories). Sparkfun will not sell Teensy boards to Adafruit. Adafruit is selling remaining stock with a bit of discount. Adafruit has made a "Teensy compatible" RPI2350-based board currently in testing with the working name "Freensy". Paul Stoffregen (PJRC Teensy biz owner) contacted Adafruit to register "concern" over the Teensy compatible wording.

The subject caught my mind.   So in some systems there is a layer between the hardware and the instructions that are part of the architecture.   An example would be the microcode that creates the Z 
architecture on IBM Mainframes (and a lot of the prior revisions of the architecture).  basically the architecture is micro-coded in the native architecture to create the defined architecture that 
folks expect.
