DFW RPI Usergroup Meeting 10/2021
So, how do you like fall? Sweaters at the ready, together with all that pumpkin, spice and what not? Just kidding, this is Texas, now you see autumn, now you don't.
Let's give this hybrid meeting thing another go, so both online and at the lab, this Saturday, party time:

Re: rpi 3b+ vs 3b? Critical supply issues - Anyone know if the OS and libraries are essentially the same?
Have not seen any. Same image across the board, same behavior, never mind what hardware it is running on, apart from performance when it comes to CPU-intense tasks on different types of CPU (like 0w vs 2b vs 3b vs 4). Only other issue might be task and thread scheduling, but that shouldn't be much of an issue between 3 and 3+.

Hi All,
So if you hadn¡¯t yet noticed, almost all of 3b+ are unobtanium around the world (and just about all models).
3b+ was $35 @ Microcenter, now selling for upwards of $80 ¨C 120 on Amazon / some Ebay etc.
I need to buy a minimum of 50, and I can still get 3B out of china. I cant buy one locally, no one has a 3b for sale, and it looks like I need to order via Alibaba tonight before prices keep on increasing.
Looking at the specs, the only change between 3B and 3B+ is more advanced wifi capabilities, and a slightly slower ghz rate on the 3B.
Has anyone had OS / library issues between the 3B / 3B+?
As an example, Farnell in the UK yesterday was showing they would have more 3b+ arriving next week (as of yesterday). Today they changed their backorder date to March 2022!
Groan!

Re: rpi 3b+ vs 3b? Critical supply issues - Anyone know if the OS and libraries are essentially the same?
All distributions of Raspbian/Raspberry Pi OS are intended to run on all models, from the original 1B to the 4B, the A's, and Zeros.? If you look in the /boot filesystem you will see different kernels, .DTB's, etc for the various types of CPUs.? There shouldn't any problems.? I have installed the latest firmware on even my RPi 1B's with no problems upon boot up.
You might try PiShop.us for quantity RPi's but the chip shortage is hitting everybody.

Re: Ad hoc WiFi connections
I might be way off what you are intending to do here, but have you looked at wifi-connect?
The wifi-connect service runs in the background of a pi:
- if the rpi has internet connection then all ok
- if the rpi does not have an active connection, then a wifi server is started on the rpi, with a definable ssid, ip etc. We use this to then set the correct wifi ssid credentials for the rpi.
- You could also pass other parameters via this method.
Wifi-connect requires network_manager, which is the heavier duty version of 'wifi lite' that rpi buster has. However you would need to change the gui to remove the existing wifi display and instead display the network manager status etc.
Our code then uses firebase as our communications middleware between our server and client rpi's. This enables us to post / change control variables, and the rpi listens for changes occurring at the firebase level, and picks up any new values.
This architectural method allows us to close about all inbound ports on the rpi as a security measure. It is the same for code upgrades / down grades. We don¡¯t push the change to the device, instead we push the notification of a package to firebase, the rpi detects the message and then acts independently on that message.
Cheers
Paul

Windows 10 does not support that mode any more and the new WiFi chips like the one in my work laptop do no longer support ad hoc mode either. Thank you Microsoft. Problem is I might need to connect to so called WiFi batteries (battery with a SBC) for infusion pumps. Per default the WiFi adapter offers an ad hoc network that can be used to change the settings. Now with Windows 10 and new hardware this possibility is usable any more. Yes, there is a workaround for that in general but there is one situation when only the ad hoc connection is all that is left. This is when the battery goes into fallback mode. It happens rarely but it works. I have read all kinds of tips on the internet, but nothing worked. I am using two UGWDR82NUH50A dongles who feature Realtek RTL8191SU which support the ad hoc mode to make sure at least the hardware should be working. I can setup an ad hoc network on one computer and the network is visible on the other computer. When I want to connect with the network via ad hoc a connection cannot be established. Connections to my existing router work fine Kind regards, Bernd Braemer

Re: Ad hoc WiFi connections
I used to set up RPi's in ad-hoc mode about 10 years ago when I was meshing WRT54G's but this was back when WiFi dongles were needed on the RPi's.? Static IP addresses were used in the 10.*.*.* address range were generated by manipulating the MAC address.? Once this is setup you'll need something like OLSR or BATMAN to help with your routing and passing infrastructure info around.
I'm not sure how well ad-hoc works on the current builtin
wifi chips on the RPi's these days.? Guess I can experiment a bit.

Re: Ad hoc WiFi connections
Found about that not too long ago as well. Not one bit happy about that.
Thx, Microsoft, so much appreciate that one.
Apparently wpa_supplican.conf can be tweaked to support ad-hoc, like
described here:
If they see each other, than we are only half-way there. Question is, do
they have matching IP addresses, and if so, can they ping each other?

Re: Short article on how to "Customize RPi splash screen & boot up video"
Right -- it just never occurred to me that there would be a use case for it. All my gear is command line only, so the idea to try anything video doesn't came up.

We are using the method on our production rpi. Just wish I knew blender better to take out a ¡®wobble¡¯ from the water renu logo, which I 360 rotated in fusion 360, then extracted out the wave pattern through the logo, then imported into blender for the 3d effect.
We use the first frame as the static splash, and it then start the video while the boot process completes.
So if anyone knows blender really well, please feel free to get in touch!

Looks as if we have a bit of a scheduling conflict at the lab. Another RPI class got scheduled for the same time. Trying to figure out how to resolve that. Either way, there's going to be a show. :)

September is upon us, might be time to figure out if you had any Halloween decoration last year, and where that might be at. Could be tricky to find in between the Xmas gear some retailers put out on display. Anyway, it's time, also Labor Day weekend, let's see who is in town. It has been suggested to broadcast from the lab, so I'm going to try to get Zoom working from there. If that all works, big TV and all that, with no policies or city ordinances against physical meetings, those might commence eventually. No promises at all.

Re: Dallas RPI Usergroup Meeting 9/2021
Just a short note to all:
?
The IrriGRAY rpi controller is close to being finished / rolled out (yeah I know we are only 3 months overdue from what I thought we could get done in 4 mths, but hey the EE had open heart surgery 8 weeks ago, my main programmer had
4 x 1 week ritual mourning periods to get through (India / covid - still).
?
But, on the positive side we are making lemonade out of lemons, I realized there was a whole group of electrical current sensors we could have added, but didn¡¯t. So on Friday our new expansion boards arrive from PCB way and we will start
baking those on Monday.
?
What I have added is 5v dc current measuring, and 24v ac current measuring in 2 Current Transformers (0-100ma), (0-2amp), plus the existing 110v (0-10amp) current measuring.
?
This means we can have the rpi cycle test every individual electrically driven thing (motors, system valves, irrigation solenoids, pumps etc) to check whether an item is aok, on the way to failing, or failed.
?
We also avoided all the global variable management issue within python by instead writing a virtual db, which gets dumped to the CF card in the event of power failure (we have the 30 second capacitor backup).
?
So probably not able to attend on Saturday, but Following month can give a decent presentation if there is interest. Don¡¯t know if the picture I attached will make it through to the group ¨C if so ignore the cuts on the plastic support
board, that is from the old design.
?
?
Apologies if this is too detailed as a quick update!
?
Best to all.
?
Paul

September is upon us, might be time to figure out if you had any Halloween decoration last year, and where that might be at. Could be tricky to find in between the Xmas gear some retailers put out on display. Anyway, it's time, also
Labor Day weekend, let's see who is in town. It has been suggested to broadcast from the lab, so I'm going to try to get Zoom working from there. If that all works, big TV and all that, with no policies or city ordinances against physical meetings, those might
commence eventually. No promises at all.
