embedded systems to learn and create
Intro to Pi & Others is a short monthly session to help get you up and running with your Pi or Other (embedded device). It is an unstructured hour-long session where you can ask questions, bring in your Pi or Other (and power supply), and get help with your project.
This month, learn the basics of GPIO and how to turn on/off a LED. We have extra green projects boards and LEDs to use. See you on Tuesday.

Discover the advantages of Power of Ethernet (PoE)! PoE is a technology that allows one to only run one cable to a distant device, just an ethernet cable. The distant device not only receives network connectivity, but also power from the single cable. This is good for small low power devices such as ESP8266 (embedded controller) boards. Hosted by Mark G. RSVP on Meetup here.
Here is a link to the presentation pdf.
What are two things that an Internet of Things (IoT) device
must have?
1. An avenue for communication.
2. Power.
There are a number of ways to satisfy both of these requirements
simultaneously. Item one can be fulfilled with:
– Wireless ethernet;
– Wired ethernet;
– Another radio based data exchange (nRF24L01 transceivers, Bluetooth)
to a network attached controller;
– 2G/3G (and friends) cellular connections;
I’m sure there are others.
Power can be handled variously by:
– A device specific transformer using a wall plug;
– A battery or set of batteries;
– A solar power panel w/battery;
– A power over ethernet cable;
I’ll discuss the ins, outs, pros and cons of these needs
and their combinations.
Show and Tell your Pi
and others explorations and issues.

MotionEye can support IPv6, see this Bug.

Why have a personal webserver? Easy distribution of files.
Why support IPv6 and IPv4? Not only is it cool, but it is very easy to do. IPv6 is the future of the internet, setting up a little personal webserver that supports both protocols will help you learn about the future.

A presentation on creating a house monitoring device, with sensors, reporting via cell phone text interface. Pretty cool stuff.
See the presentation pdf here or the page here or at Google here.
9:30 AM
ESP8266 OTA (Over the Air) Updates with Arduino IDE. OTA update is the process of loading a new firmware to ESP8266 module using WiFi connection rather than a serial communication. This type of functionality is extremely useful in case of no physical access to the ESP module.
This presentation, by Greg Lawrance, will include a hands on session for those who want to learn more. Please bring your PI, and preload the software referred to in the meetup announcement.

PHP the language of the Web (well one of the languages) can connect to SQLlite on the backend, storing your dynamic content in a database. In this presentation, you will see how to make that connection, and directly populate data (into your database) from the Web.

Intro to Pi & Others is a short monthly session to help get you up and running with your Pi or Other (embedded device). It is an unstructured hour-long session where you can ask questions, bring in your Pi or Other (and power supply), and get help with your project.
We plan on holding these sessions once a month on a Tuesday night. If you are looking for a bit of help, this session is for you.

You have seen Craig carrying around routers, but he has never shown you what is inside. In this session, Craig will show you the Open Source alternative to Router Software, which supports over 1000 router models. There is a good chance your router is supported by OpenWrt/LEDE.
https://wiki.openwrt.org/toh/start
https://lede-project.org/toh/start
OpenWrt/LEDE also have excellent IPv6 support. What could be better to prepare you for the future of the internet.

A high-level Python Web framework that encourages rapid development and clean, pragmatic design, Django takes care of much of the hassle of Web development so you can focus on writing Web apps without needing to reinvent the wheel.
Free, full-featured, and open source, Django is well documented, offering an attractive avenue for Python newbies and experienced Web developers to improve and apply Python programming skills.
This introductory presentation will show you how to set up a Django development environment as we explore the many ways you can set about learning Django.

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
Resource: Craig Miller

Filesystems is what keeps track of the files on your Raspberry Pi. Linux supports several types of filesystems (including the ones used by Macintosh and Windows).
Chris K. will cover the basics of filesystems in the context of the Pi. We will look at the boot sequence, types of filesystems and their specific usages, and then we will dive into the structure of the both the boot and root filesystem (rootfs) partitions.
Arduino Day 2017 will be 1 April this year. Unfortunately, there are no Arduino events in Victoria, but there is one in Vancouver, Washington, USA.

Hayward will be talking about Python Webservers. The presentation will cover the basics of what they are, how they differ from a traditional web server, and provide examples of (and discussion around) some projects that he has setup using a python web server.

I²C. A common 2 wire bus, a brief background on how it works, and simple programming the Pi to read from and write to I²C devices on the bus. Devices include: External LCD display, 7 segment LEDs, and Addressable LED lights to name a few.
Join us and learn how to drive the I²C (pronounced eye-squared-see) from your Raspberry Pi.
9:30 AM
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.
The internet has run out of IPv4 addresses (as of Oct 2016). The future of the internet and networking will rely on the “new” IPv6 protocol.
There’s more to IPv6 than a really big address. Come and learn the basics of this foundation of the next generation Internet.
We’ll cover:
• Why do we need IPv6?
• Not your Grandmother’s IP
• IPv6 Addressing
• Hands on session (Please bring a computer for the hands on session: Pi, Laptop, BSD machine)
Resource: Craig Miller
9:30 AM
The VicPiMakers and Others, includes many devices besides the Raspberry Pi. At this meeting, Greg, will provide an over view of the ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU capability. He will highlight several different modules and dev boards, and the software options of Arduino code, and MIcroPython. There will also be a hands on session with the ESP devices.

If you ever had questions on how to integrate multiple devices together with 21st century security all controlled via a simple (looking) Android App, you won’t want to miss this meeting.
Join us for a similar but different demonstration of controlling LEDs running on one of the “Others” (a Beaglebone Black) using SSH and BSD. If that wasn’t enough, Mark G will also be showing a Raspberry Pi camera used to confirm that state of the LED, all under the control of a custom Android App.
