PLEASE NOTE: earlier time for this meeting. There is another group who will be using the room at 10:45a.
AI is not just for the big guys any longer. It is possible to run an Artificial Intelligence program on your Pi 4 or Pi 5. In this presentation, we’ll learn about how to run an several AI models on the Pi, the advantages and disadvantages of each.
We’ll open the floor to ask the AI questions (via a web interface on the local network), so bring a laptop, all over IPv6!

How to make a bread dough proofer from an Amazon cardboard box, or more accurately, an example of Proportional Integral Derivative control of a process. Yes the box has actually proofed bread dough that was used to make cinnamon buns.

Happy 2024!
Mark will share how to create a home git server (take that github!) and the workflow with it.
Basic Git Home “Remote” Server Using
SSH With Gitolite
Mark G.
January 13, 2024
An installation and configuration of a source code control system (SCCS).
The SCCS uses the Secure Shell (SSH) protocol, the Git version control
system (VCS), and a software package named Gitolite. A user of the system provides a public key that is tied to configured identities for the purposes of access control to git repositories. The repositories configured on this server are intended to be used as remotes, in terms of how git defines a remote.
This demonstration was hosted on a FreeBSD 13.x operating system running on a raspberry pi 4.

By measuring the interior chip temperature over a few seconds of a chip cooled by a heat sink, you can calculate the watts dissipated by the heat sink. The DS18B20 measures temperatures up to 125℃ at the interior of the chip.
This is a useful measurement If you are making your own heat sinks out of copper tubes or folded aluminum sheathing, You can also compare the effectiveness of different heat sink compounds this way.
The presentation is at this bookmark in a longer presentation on how to set up a Raspberry Pi Pico as a Blue Board learning tool. Blue Boards are available for free from George at 250-893-7423
A 2 part presentation, Pi Essentials, always good to know. And using DNSMasq to DNS-up your house (never think in numbers again)
Pi Essentials will be a beginner level introduction to some of the things you can (or maybe should) do when the Pi starts up. Nothing requires more than a few lines of code, and these are the sort of add-ons that can go with your main project. Included are buttons to put the Pi in standby mode, and start it running again, and pilot lights to show whether or not the Pi is running. A sound notification at start-up using simple text to speech, and how to put an icon on the desktop that can be clicked on to start your program are also included.
The way these utilities are organized and documented will illustrate one method of keeping track of your SD card contents.

Naturally, you can run PiOS on your Raspberry Pi, but are there other options, which have a full GUI (XFCE). Turns out, you can run Alpine Linux with full GUI on the Pi. A lighter-weight distro, which also doesn’t require systems.

Why just run your own video conferencing server, when you can simultaneously run that AND mail, calendaring, contacts, calls, IM, file sharing, remote backup, and a web-based office suite, all in one intimidating package. Get your own thrift-store Google G Suite going with the open source Nextcloud platform on a tiny Raspberry Pi! Great for the privacy-conscious, the independent, and masochists. We’ll do it the hard way and make configuring Jitsi look like recess at kindergarten (and then do it the easy way). Warning: the hard way will race through dependencies including Apache, PHP, MySQL/MariaDB and openSSL, so expect some mild suffering.

I have been playing with Galene for over a year. And have been using it on a weekly basis to do video conferencing with some friends in Ottawa. It is much easier to install than Jitsi, but lacks some of the finer points of jitsi.
Still, you can install and run it on a Raspberry Pi (even a 3b+ !). In this presentation, I’ll show how easy it is to install on a Pi, and you can run your own personal video conferencing server.

We will be having a discussion about Projects that we are working on, but haven’t shared with the group. These can be projects that are successful or ones that just didn’t work out and have been abandoned. We’ll enjoy hearing about other’s projects, and perhaps even offer to help.

NetSIG is a Special Interest Group focused on computer networking. Building networks for Today and Tomorrow!
Last month we explored MACVLAN interfaces, and how it makes it easier for Linux Containers (LXD).
This month, BRING YOUR PI, and a 32 GB SD Card, and we’ll do a Linux Containers INSTALL FEST on your Pi.
We will be meeting in-person at Quality Foods (small boardroom upstairs), bring a laptop and have Wireshark installed. This will be hands on. PLEASE BRING an ETHERNET dongle/port as we will be ssh-ing into your Pi, and configuring Linux Containers.

After using Linux Containers (LXD) for a couple of years, Craig will share how to easily get your containers connected to the internet using a MACVLAN interface. No reconfiguration of the host is required. This technique can be used on Pi’s as well as other hosts.
We will set up containers using the MACVLAN network attachment, discuss limitations, and even run LXDware, a web-based GUI for LXD on a Pi.
