Sat. Feb 11 2023 – Linux Containers on the Quadra

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.

We will be holding a Hybrid meeting (in-person & Jitsi).

Sat. Dec. 10, 2020 – T’is the Season

T’is the season for bright lights and Raspberry Pi fun.

T’is the Season!

In this talk we’ll look at a ModMyPi Programmable Christmas Tree (MMP-1021), which sits atop the 40 pin header and presents a set of individually controlled LEDs. The trick to practical and easy use of the tree is via GPIOZERO, a fantastic python module. We’ll integrate some sensors as well, since GPIOZERO makes them very easy.

Sat. Oct 22, 2020 – Old Man Savers

George will share his old man savers. Consumer kitchen appliances are designed for one size fits all, not for my personal needs. My needs change as I age, and I need alerts for faults.

  • I like to turn off my drip coffee maker as soon as coffee is brewed. If I forget, it wastes electricity (500watts) and spoils the coffee. If I forget to insert the carafe, I’ve got a mess. A timed relay with a contact sensor for the carafe solves the problem.
  • So as not to overcook the meat, I turn off my induction hot plate based on a thermistor inserted into the meat to trip a relay to power off the hot plate.
  • A centralized monitor and alarm system, with text message notifications, can be tailored to one’s specific needs. My monitoring system needs to include at least 9 sensors:
  • Exterior door that gets left ajar.
  • Bathroom light gets left on
  • Bathroom water flooding
  • Fridge power lost
  • Fridge temperature too high
  • Freezer power lost
  • Freezer temperature too high
  • Exterior hall temperature
  • Smoke detector

Dave will share his work in running Marine Navigation on a Pi including:

  • hardware requirements
  • how the zero could be used, but there are drawbacks
  • I was unable to get a pi 4
  • at George’s suggestion, I decided to go with the pi 400
  • hardware modifications to integrate the GPS unit within the pi 400 case
  • introduction to and a brief overview of the OpenCPN Chart Plotter Navigation software
  • some ideas I have to make a more “system-critical” GPS solution (will implement if I have time)

Sat. Feb. 26, 2022 Making a music player – bits of Python causing grief

I decided to build my own Raspberry Pi music player using Python, as the available players didn’t really do what I wanted. This is Python at the beginner level, and the saga of making the player. Mostly it is about the little things in Python that caused me to stumble for a while. The music player is functional, the interface isn’t elegant, and I learned a few things about Python programming. – Don
