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.

 

 

Jan 13, 2018 – Python Webserver

10:30am

Personal IPv6/IPv4 Python Webserver

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.

Suite 303 771 Vernon Ave, Victoria, BC

Please join us for a discussion/learning day about embedded projects. Bring in your Raspberry Pi’s, ESP8266, Arduino, whatever, and ask/answer questions and share what you are doing.

Look forward to seeing you there!

January 14, 2017 – Blinky Lights on BSD

Blinky Lights on BSD (Beaglebone Black)

Saturday, January 14, 2017
9:30 AM

Victoria Computer Club
85A Burnside Rd West (at Wascana), Victoria, BC (map)

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.
