November 24, 2018 – Docker and a webserver on rpi

Docker is a computer program that performs operating-system-level virtualization, also known as “containerization”. A Container is a lightweight application component including all the required elements (libraries, config, etc). Containers can be quickly started up without polluting your file system with libraries, and config files, and easily upgraded with one command.
In this presentation, we’ll install docker on the Pi, and get nginx webserver up and running in a container. The presentation material can be found here.

November 10, 2018 – Lights Out!
Saturday, November 10, 2018

Q-College, Suite 303 – 771 Vernon Ave, Victoria, BC
Hosted by George Bowden and Craig Miller
LIGHTS OUT, a possible life saver. An acquaintance fell in the washroom and was unable to raise attention for thirty hours, and never fully recovered. The monthly cost ($50) of wearable alert bracelets and the habit of not wearing them is a large risk to seniors living alone. This alarm system, based on an ESP8266 and a php web app, alerts friends that a bathroom light has been left on for way too long. The link to the presentation docs is here.

A shallow Dive into Adafruit’s Circuit Playground Express
The Circuit Playground Express is a small, cheap($32) dev board from Adafruit Industries designed to introduce electronics and programming to the novice. It’s built around an ATSAMD21 ARM Cortex MO processor and is programmable with either circuitpython or Microsoft’s ‘Makecode’ block programming interface. The board also houses a variety of sensors (motion, temperature, light, touch), buttons, a slide switch and IR transmit/receive capability. In this presentation I’ll demo some of the easier projects that I’ve mastered and maybe include something using the Adafruit Crickit, and add-on board for the CPX designed for simple robotics. See the reading list here.

September 22, 2018 – ESP8266 Web Controlled LEDs (part 1)
10:00am
Camosun College
Bldg: Technology Bldg, Room: Tech 259 – 4461 Interurban Rd, Victoria, BC (parking at lot 8 for park users) presentation pdf
In this session, we’ll cover programming Neopixel LEDs driven by the ESP8266 using a Web Interface. We’ll cover the hardware interface to the LEDs as well as the web interface (running on the ESP8266 utilizing the PL9823).
In Part2, we’ll harden the installation by adding TLS/SSL and IPv6 support via NodeRed running on a Pi
September 8, 2018 – What I did over the summer

Welcome back from Summer. At this meeting we’ll be doing a show and tell, talking about what Pi (and others) projects we worked on over the summer break
June 23, 2018 – Interfacing Sensors and Devices to Microcontrollers
10:00am
Q-College
Suite 303 – 771 Vernon Ave, Victoria, BC
Jim’s presentation focuses on interfacing sensors and devices ( modules) to microcontrollers followed by actual examples. Two or more examples will be discussed using I/O from pulse inputs, IR transmitters/receivers, accelerometers, load cells, Bluetooth SPP and motion controllers.
See the presentation document here.
