In this session, we’ll cover programming Neopixel LEDs driven by the PL9823 using a Web Interface. We’ll cover the hardware interface to the LEDs as well as the web interface (running on the PL9823).

In Part2, we’ll harden the installation by adding TLS/SSL and IPv6 support via NodeRed running on a Pi

Feb 10, 2018 – Power Over Ethernet

9:30am
Q-College
Suite 303 771 Vernon Ave, Victoria, BC

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.

 

 

Dec 9, 2017 – Esp8266 Over The Air Programming

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.

Intro to Pi & Others #2 – Tues Nov 21

Tuesday, November 21, 2017
6:00 PM to 7:00 PM
Q-College
Suite 303 771 Vernon Ave, Victoria, BC

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.

Oct 28, 2017 – Open Source Routers with OpenWrt/LEDE

9:30 AM

Q-College, Suite 303 771 Vernon Ave, Victoria, BC (map)

routerYou 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.

OpenWrt/LEDE also have excellent IPv6 support. What could be better to prepare you for the future of the internet.
