Serving The Web With A Slice Of Pi

Although small in size, the Raspberry Pi and other embedded Linux boards can be used as very capable web servers.

Instructor Don Woods will show you how to set up a Web server on a Raspberry Pi and get around the little snags to be able to access your Pi from outside your local network.

The entire tutorial is available here:

Note: This will be our last Meetup before the summer holiday season. We will reconvene in early September. Have a good summer, y’all!

June 25th Meeting

Low-cost High-quality PiFi Audio

Presented by Stuart Hertzog

Tired of iTunes? Time for PiTunes! — HiFi audio from your Pi.

You don’t need a PC or laptop to enjoy listening to hifi audio from your personal collection or Internet streaming. And you won’t have to endure the convoluted iTunes interface.

A low-cost Digital Audio Converter (DAC) or DAC and Amplifier such as offered by HiFiBerry or IQAudio will turn any Raspberry Pi2 or 3 into a low-cost and energy-efficient MPD audio server controlled from a Web browser or an iOS/Android app.

Join us as instructor Stuart Hertzog explains how to set up a DAC on your Pi and demonstrates the free and open-source Linux audio software PiMusicBox, Volumio, RuneAudio, and MoOde Audio.

Discover PiFi audio and a world of listening pleasure!

Python Tutorial Part Six: Functions and More

By Simon Bluck

Table of Contents

This session adds to what was learnt from Session 2: Syntax and Constructs, and goes on to cover some further language constructs. The sessions now broadly follow the standard tutorial, but in a very condensed way. You are very much advised to refer to the tutorial for a fuller coverage of the language; and indeed, to the full language reference for complete coverage. Some of the examples shown here are taken from the tutorial.

A Live Flight Data Feeder

Presented by Gordo

One of the many cool things you can do with your Raspberry Pi is to add a special $30 DVT-T USB dongle and install some software to turn your Pi into a live flight data feeder for FlightRadar24.com and FlightAware.com.

The recommended one is an ADS-B USB Dongle (R820T), which includes a small indoor antenna, but I purchased an equivalent one from Amazon at a very reasonable cost.

Among the benefits of this project are gaining free premium memberships with both sites; the ability to monitor flights overhead in real-time; and learing a bit about how to install third-party software via the command line.

In this presentation, I will give an overview of the hardare and software required and perform a quick walk-through installing the FlightRadar24.com feeder. If time permits, I will also demonstrate installing the FlightAware.com feeder.

Since these feeder stations are location-dependent, you will have to perform your own install at the place from which you’ll set up your Pi feeder and antenna.

Place: Victoria Computer Club, 85A Burnside Rd West (at Wascana), Victoria
Time: 9:30 a.m. – 12:30 p.m.
