Learn how to measure the electrical world using your embedded device. In this talk, we’ll answer the following, and show you lots of cool stuff:

  • When does Ohm’s law apply?
  • Measuring inductance and capacitance, and formulas for these
  • Recording transient currents when a motor starts and stops.
  • Protecting devices with inrush current limiters and transient suppressors.

Sat Apr 27, 2019 – Wireguard IPv6 VPN – IPv6 in the Land of NAT

10:00am
Camosun College
Interurban Campus
4461 Interurban Road · Victoria, BC
Tech Bldg, Tec 177(parking at lot 8 for park users)

Go to any Starbucks, McDonald’s, the airport, the Library or even Camosun, and you will find yourself on a NATted network. How to get on the IPv6 Internet when stuck behind NAT? Enter the VPN (Virtual Private Network).

In this talk, we’ll show you how to use a VPN to get to the IPv6 Internet, but also share it with your friends (using an OpenWrt router)
Craig’s presentation can be found here. Your IPv6 web funny, Toads, can be found here. (IPv6 required).
The IPV6 utility, IPvFoo, is a Google and Firefox extension/addon, the github version can be found here.

Sat, May 11, 2019 – Useful Tools

Useful Tools (git, sshfs, bash, etc)

Over the years, we have found certain software tools, which not only make our life easier but make the project more fun to do. In this meeting, we’ll share some of these software tools, and ask the group for other tools that they have found useful.

February 23, 2019 – Linux Containers on the Pi: A Server Farm in the Palm of your hand

Camosun College
Bldg: Technology Bldg, Room: Tech 177 – 4461 Interurban Rd, Victoria, BC (parking at lot 8 for park users)

Another container technology which can also run on SBCs is Linux Containers (LXC/LXD). Each LXC Container appears to have its own network stack. And therefore is much more flexible than Docker.

We’ll run 20 webservers all with individual addresses, all listening on port 80, on the Pi, something that can’t be done with Docker in its NAT-constrained world.

See Craig’s documentation here.
