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.
?

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
Hi Cornelius,
I will be out of town for a lake house weekend.
Here is a little read for you regarding things to hack. Please keep it confidential as it is my employer. Thank you!
Have a nice weekend!

Why would you wanna build a cluster of Raspberry Pi's? It's not always about performance!
Building them is the easy part, really. Running stuff on them can be another story. Check out this video:

Guess what, if you intended to celebrate Christmas in July, you now have another year to prep. Time to escape the heat, spend a Saturday morning talking tech, then dive into the pool. The tech part we have covered. Got something interesting to show? Talk to me.

At the last meeting I had promised to send out an email about
FreePBX. I was expecting to just pass on information about whenever
the Philadelphia Linux User Group (Plug) has a talk, but I don¡¯t see
it in the schedule yet. It will probably still happen but I don¡¯t
know when. At the moment their meetings are online using Jitsi so
they are easy to join . There are also
Libera Chat IRC channels #plug, #asterisk and #freepbx and youtube
videos.
I am nowhere near an expert, but I have got it working. I have spent
an enormous amount of time on it but I also found it very rewarding.
It is one of the more complicated pieces of software I have used so
it is a bit much to discuss for a single email. In this email I will
give an overview. Hopefully, I will follow up. I would be happy to
answer questions and be corrected. Maybe at some point I would be
confident enough that I could give a talk if the meetings are still
online.
Asterisk is the actual PBX software. It is probably available as a
package for most distros or it can be compiled from source. FreePBX
could be thought of as a suite that includes Asterisk, a web
interface, fail2ban, OpenVPN, etc. It has both free and commercial
modules. Usually you install it as it¡¯s own distro. The normal
version is for x86 and is based on CentOS 7.x. There is a Raspberry
Pi image based on Raspbian. The x86 one can be registered (paid for)
so you can use the Pro features, the Raspberry Pi one cannot ¨C it
shouldn¡¯t be used commercially. Some components are also missing for
RPi (such as the web interface for the firewall). There is a docker
image but there are many reasons you should not install it this way.
The current major version of FreePBX is 15. There is a beta for 16.
They had planned to upgrade to CentOS 8 but because of all the
drama, they are staying with the old OS. A lot of stuff is very out
of date (old OS/kernel, Apache/PHP, etc.) I think it must be
difficult considering how many parts there are and what needs to be
tested. Unfortunately the Wiki documentation is also often out of
date. There is a forum.
Maybe I should have started by explaining what it does. I expect
that most people now are actually using VOIP even if their house
connection is still POTS. Instead of using a normal telephone
provider, you can pay a VOIP provider for a phone number. (I am
using voip.ms and I¡¯m very happy with it.) You can even get phone
numbers in other countries. The FreePBX software lets you make a
connection over the Internet to one or more ¡°trunks¡± and you can
configure ¡°extensions¡± which are either physical VOIP phones, VOIP
to analog adapters or software phones.
I have two Android phones and use the Zoiper App. Each one is an
extension. Zoiper is also available for regular computers and I¡¯m
sure there are other clients also. I have a US phone number that
will ring on my handy mobile phone anywhere I am that has good
Internet. My German router (Fritzbox) can talk to the PBX, for the
PBX it is a second "trunk". So I can get/make phone calls using
either number. The dial rules determine whether to use the German or
American phone number when I make a call. I'm running my PBX as a
virtual machine on my home server but I plan to get a Lenovo thin
client. It is installed on my RPi but I didn't configure it yet. It
may be that because of missing modules or excessive writing that it
is not practical but I can't say yet either way.
There are a lot of neat things you can do such as video calls, Fax,
SMS/MMS, etc. Some of this I have working, some not. And you can
program responses such as dialing an extension to get voice mail or
the weather.
Best wishes,
Jon Wolfe

That's 09:00CDT, not 08:00CDT. Was: Re: Forth2020 Usergroup Meeting, tomorrow (7/10) @ 0800CDT
So much for time zone conversion. 14:00UTC == 09:00CDT, not 08:00CDT.
Sorry about that.

Re: DallasRPI Meeting 3/7/2021, 10:00CDT
No biggie, enjoy the drive :)
No telling if Fritzing will be up to anything by then. This thing is huge. It works on Ubuntu, though, so there's a way to show what it *should* be doing.

This is the longest I've seen the Pico's available at the Dallas
MicroCenter since they first released.? Still list at 25+ in
stock @ $3.99.
BTW, it's fairly easy to raise the clock frequency to 250MHz and
it doesn't appear to heat up significantly!? They will go much
higher but not without some problems, depending on what parts you
are wanting to use (GPIO, I?C, SPI, USB, Flash).

Naturally, you're doing this at your own risk! :)
Then again, crimney!? They're only $4 a piece. :)
Have fun!

I stand corrected and J was correct.? My slysdexic memory swapped some bits.
Released just a year after Fortran,
is the second oldest high-level
programming language still in
widespread use today. Lisp was developed by
John McCarthy, a legendary
computer scientist, who is considered one of the founders of the
discipline of artificial intelligence (McCarthy co-authored the document
that coined the term ¡°artificial intelligence.¡±) FORTRAN was released in 1957 and LISP in 1958, per ? -- ? ?_____
