Sat, Nov 23, 2019 -Electrical measurements in the unsteady state

10:00 AM to 12:00 PM

Learn how to measure the electrical world using your embedded device. In this talk, we’ll answer the following, and show you lots of cool stuff:

  • When does Ohm’s law apply?
  • Measuring inductance and capacitance, and formulas for these
  • Recording transient currents when a motor starts and stops.
  • Protecting devices with inrush current limiters and transient suppressors.

Intro to Pi and Others: Part 4

Light it up!

Tuesday, May 21, 2019
6:00 PM to 7:30 PM
Q-College
Suite 303 771 Vernon Ave · Victoria, BC

Intro to Pi & Others is a 4 part series of short monthly sessions to help get you up and running with your Pi or Other (embedded device). It is a structured hour-long session where you can ask questions.

Please bring in your Pi, HDMI cable, and power supply. All other equipment will be provided.

This is a four-part series with each session building on the previous sessions, where Pi basics of software and hardware will be explored. Read More

February 23, 2019 – Linux Containers on the Pi: A Server Farm in the Palm of your hand

Camosun College
Bldg: Technology Bldg, Room: Tech 177 – 4461 Interurban Rd, Victoria, BC (parking at lot 8 for park users)

Another container technology which can also run on SBCs is Linux Containers (LXC/LXD). Each LXC Container appears to have its own network stack. And therefore is much more flexible than Docker.

We’ll run 20 webservers all with individual addresses, all listening on port 80, on the Pi, something that can’t be done with Docker in its NAT-constrained world.

See Craig’s documentation here.

November 24, 2018 – Docker and a webserver on rpi

Camosun College
Bldg: Technology Bldg, Room: Tech 177 – 4461 Interurban Rd, Victoria, BC (parking at lot 8 for park users)

10:00am

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

10:00am
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.

October 6, 2018 Adafruit’s Circuit Playground Express

Saturday, October 6, 2018

10:00am
Q-College, Suite 303 – 771 Vernon Ave, Victoria, BC

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.
Hosted by Paul and Craig Miller

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
