embedded systems to learn and create – 10 years of making, learning and sharing
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.
See you on Saturday.

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.
Gordo is doing a second session on March 14th.

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?
