Deid will do a presentation on OpenSCAD. A programmatic method to create and print 3D things. This does not have much to do with the Pi, etc., but it is code, and the code will run on a Pi 5.
This is the perfect thing for someone like me who flunked scissors and crayons, but who is not bad at coding.
This session launches a two‑part deep dive into building a resilient, secure, and remotely accessible Raspberry Pi platform. Part I focuses on preparing a Raspberry Pi to operate from an external SSD using an encrypted LVM layout, establishing a solid foundation for containerized services in Part II.
The presentation walks through installing Debian 12 (Bookworm) onto the SSD, applying practical hardening measures, and structuring the system so that both the root filesystem and future container volumes reside within an encrypted partition. An unencrypted boot partition completes the setup, ensuring compatibility with the Pi’s firmware while maintaining strong data protection.
From there, the session moves into remote‑unlock and secure‑access workflows. Attendees will see how Dropbear is integrated into the initramfs to allow remote SSH access for unlocking the encrypted volume. The talk then introduces Cloudflare Zero Trust (formerly Cloudflare Tunnel), demonstrating how cloudflared can provide authenticated, firewall‑friendly access to both SSH and HTTP services without exposing the Pi directly to the internet. The session concludes with an introduction to Incus, the modern fork of LXC, preparing the ground for containerized feeder services in Part II.

Mark’s Lenovo M93p Tiny PC and how he got it up and running.
Stuff includes:
– changing the BIOS battery, – re-pasting the CPU, – trying to add a mini-pci card — getting BIOS locked out when card is inserted (unauthorized!) — updating BIOS with trick to unblock the unauthorized card. – running the BIOS updater, – fixed, noisily the problem
Anyone want to bring their M93p tiny and do this stuff?

Object detection (identification of objects and their location in an image) is one of the most useful and widespread application of artificial intelligence, even on microcontrollers.
This demo shows how free, web-based tools designed for memory-constrained devices at www.edgeimpulse.com can be used to collect a dataset, train and test a neural network, and deploy it to an Arduino microcontroller to detect pop bottles.

This presentation will look at how to write a program in the Python programming language using a graphical user interface (GUI) library named PySide6.
Our example program will accept a string of text, usually an HTTP link, and perform some sort of processing on said string. As part of the architecture of the program, to increase generality and usefulness, we use a shell (Bourne is the example) script, which is used to hold the command or commands processing the string.
The Python GUI program will call this external program and capture its output.
We will also take a brief look at PyInstaller for creating a distributable single executable.

VicPiMakers is taking a well-deserved summer break. We will be back to our regular bi-weekly programming in September. In the meantime… join us at our Linux SIG or NetSig. See the blocks on the right for the details and links.
Click the image to see the Google Sheet updates, and see the following posts for more details. Technical talks, either full-length or a shorter lightning talk, in person or via Jitzi, are appreciated. Let us know.
A continuation of Pi Pico SD Card. With the addition of humidity and barometric pressure and more fun with the charting. Deid’s presentation notes are here.
Discover Virtual Environments in Python, and how to manage them. Additionally, we will cover variable typing, and how it makes your code more readable.

Two input XOR logic is implemented with an artificial neural network written in MicroPython on a Raspberry Pi Pico microcontroller as an educational exercise of applying artificial intelligence to control machinery (LEDs in this example).
The intent of the presentation is to provide enough detail for others to get started on their own projects incorporating an artificial neural network on a microcontroller (or single board computer).
I’ll be presenting referring to a document that will be available at a GitHub repository (along with MicroPython code and a couple of Jupyter-Notebook files that will be discussed during the presentation): https://github.com/James-Canova/XOR_NN.git

In February 2025 Vic Pi Makers and Others will discontinue our membership with Meetup.com. This domain will be the source of information. From here, vicpimakers.ca, our members and friends can post and share our meetings and events to their favourite social media accounts. Many thanks.
