Presenter: Mark G. Topic: Using ZFS on A Souped-Up Raspberry Pi 5
Abstract: This presentation gives an overview of the Zettabyte File System (ZFS) on a Raspberry Pi 5. The Pi 5 has 16GB of memory, helpful since ZFS is memory hungry. The operating system is 64-bit Raspberry Pi OS (Trixie). Topics covered are how to enable ZFS on Raspberry Pi OS, how to create a ZFS storage system, and some examples of ZFS in use.
Of note is the Pironman 5 Max case used to hold the Pi 5 and its built-in ability to allow for two NVMe drives to be attached directly to the Pi’s PCIe controller. ZFS works much better with directly attached drives rather than USB attached drives.

George will talk about his homemade “Clapper” that he uses to turn things on and off.
Robert and I, Deid, will do an informal demonstration of Meshtastic, a Lora radio mesh network. (meshtastic.org) I say informal as I just made this work yesterday, with a second node this morning. I’m hoping that Robert will help me fix what I have done wrong.

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?
