No DFWRPI September Meeting
This first September weekend I have a scheduling conflict, with the
conflicting event being a must-attend-not-gonna-miss-this-one, so there's
not gonna be a DFWRPI users group meeting.
See all y'all in October!

DFWRPI Usergroup Meeting 8/2023
In case you are not yet hibernating in your pool 24/7, and/or brainfried into oblivion, it's time for another DFWRPI gettogether, both in person at and online. Got something to show, questions and what not, talk to me!
In case you can't make it in person:

Dallas Raspberry Pi Usergroup Meeting 7/2023
July already, year's half done. Unless you don't like the heat, in which case you might be fully done. Hope all y'all got flags, grill and all the fixins ready for the 4th. If you are still in town, or in a place with reasonable connectivity, there's this:
As always hybrid, both in person at and online. Got something to show? Feel free to speak, doesn't have to be a presentation, no slides required, doesn't even have to work properly.

Still installs on a Pi 1 <--- regression test. Kinda.
Also interesting, that thing is so fresh (OS release, not the 1, obviously) that "apt update" and "apt upgrade" come back right away without downloading updates.

Dallas RPI Usergroup Meeting 5/2023
Any scary stories about tax day? Hopefully you made it through that mess alive. Also, both mentally and financially unharmed.
Repeat after me: taxation is theft.
Anyway:
New month, new luck. As always, there's the first Saturday, the day of all days to talk shop. Who's got something to show off, found some new cool gear and all that? Talk to us!
Nothing ever changes, so we meet both in person at, and virtually further down:
999 E. Arapaho
Richardson, TX 75081
BTW, it appears as if Zoom enforces authentication, completely ignoring the conference setup's settings to skip that. So to participate, might want to set up a basic Zoom account (maybe even using a throw-away email address), use that when starting that app, or within the browser.
Party time:

Re: Needing some help with usb wifi adaptor / kernel headers mismatch - any ideas?
Cool, thx, good to know!
One thing with having to manually add stuff to a kernel is that in the long run you might end up supporting it yourself, because whoever came up with the initial driver no longer supports it, so you are stuck with an older kernel version, which is OK as long as you don't need any of the features a newer release supports, and all your software, including external tool chains, work on the older kernel. At the end of the day kernel and driver support is not exactly your business concept....
Thx!

Still having issues with it, so I have ordered a couple that supposedly will work without needing to compile drivers - they arrive tomorrow morning. Hopefully they will work.
As soon as I get something working, we will be designing a 2 part water proof printed case.
Here is our new connections panel. M12 Cables manufactured in China. M12 Connecters soldered to circuit board, with ip67 seals on the panel. Inside of box and lid sealed with resin. Overlap seal between box and lid, with butyl tape as final seal. Airtight.

Subject: Re: [dallasrpi] Needing some help with usb wifi adaptor / kernel headers mismatch - any ideas?
This here:
<>
states at the bottom of the page:
------------------------------------------------------------------------
i was having this same problem, this is what i did to fix it:
after running the suggested above command sudo apt-get install raspberrypi-kernel-headers
i found my headers in /usr/src
so i copied them to my build folder, but first i had to make one sudo mkdir /lib/modules/5.10.103-v7+/build/ then copied the headers into that new build folder sudo cp -r /usr/src/linux-headers-5.10.103-v7+/*
/lib/modules/5.10.103-v7+/build/
now when i run my makefile, my drivers compile without the above error message
------------------------------------------------------------------------
I had a similar problem two or three years back. Found a script that pulled the exact kernel version I was running at that time out of Github. Built that from scratch, which, IIRC, did the trick. But then I also slept since then.
I wonder if that SDHC card is still somewhere.
BTW, would it perhaps be easier to use a known-supported USB dongle and a USB-A to USB-A extension cable so that not just the antenna, but rather the whole dongle resides outside the cage?? Like this one:
<>
You'll still have to find some kind of plastic housing for that thing.
Advantage is, you don't get much signal loss through the antenna connectors. Disadvantage, the antenna is smaller than an external one, and, depending on the dongle's power draw, the cable must not be too long.
