Suite 303 771 Vernon Ave, Victoria, BC (map)

We’ll recap what we learned in Part 1, and then expand our knowledge of how IPv6 really is different from IPv4 by learning about:

• Router Advertisements – Good info from the router

• Dive into DNS a bit more, learning about AAAA records

• Sniffing the network with wireshark

Why invent the wheel? Over the years Python has adopted of features from other languages, skillfully designed and proven useful and effective:

Two Python mini-languages: regular expressions, and string formatting.

As a plus an intro to Tkinter, the built-in Python GUI. Tkinter is a binding to Tk, one-half of the Tcl/Tk language, developed over the last 25 years.

October 22, 2016 – Python 5: Exceptions

Python provides for the raising and handling of exceptions. An exception is used primarily for managing an error situation but is also handy in other circumstances e.g. an exception is used internally to end loop iteration.

A full writeup for this session is available here.

September 24, 2016: Python 4: Input and Output

Introduction

Welcome back to the Python presentations!

It’s been a while so first a short(ish) recap of the previous 3 presentations, including in more detail the Input And Output section of session 3. Then I’ll discuss some useful Python Tutorials. And finally, we can go on to cover some further aspects of the language.

June 11th Meeting

Pi Weather Station Part 1: Temperature and Humidity

Instructor Deid Reimer will demonstrate how to:

  • Measure temperature and humidity with the Pi
  • upload the information for display to a web server and
  • display the information in text and graphical form.

May 14th Meeting

Using the GPIO Pins on the Pi – Part 2

By Deid Reimer

This meeting we’ll pick up on the Pi GPIO pins (Part 2), looking at input, using switches (push buttons). You’ll learn how to not only have your Pi illuminate lights or close relays, but also to take input via GPIO. Using the input and output GPIO capabilities of the Pi, one can create a home automation system, or even replace your “Nest” thermostat with the Pi.

Bring your Pi and get hands on help after the presentation.

In this meeting we’ll learn:

  • What is VNC
  • Why would you want to use VNC?
  • Basic Networking
  • VNC Server, VNC Client
  • Other remote GUI methods, X-Windows
  • Demo

Bring your Pi if you have one so you can set it up for VNC access as the presentation progresses.

Outline

  • What is VNC?
  • Why would you want to use VNC?
  • Basic Networking

Building An Arduino Obstacle Avoidance Robot

by Eileen Amirault (with a little help from Cody Gregory)

Last March Break, I read a book that changed my life. I immediately ran out and purchased an Arduino. A Raspberry Pi was not far behind. After a few months of experimenting, and watching YouTube videos of kids building Obstacle Avoidance Robots (OAR), we thought it looked like a good first project. We call it Bobby OAR. An OAR is an autonomous robot that rolls around and avoids obstacles by using sensor input. Then, based on programming, finds an alternate path forward, avoiding obstacles along the way. We had most of the components from various kits, so only a chassis and wheels needed to be ordered. Or was there something else?
