Learn the basics of Computer Languages: c, PHP, Python, Bash
All four languages will be covered, where it will be apparent the similarities and differences of each.
Be sure to BRING a LAPTOP, as these are hands on sessions.
This session: Libraries
QCollege has graciously offered to use their campus for our fall meetings. This will be a hybrid meeting (in-person & on Jitsi). Seating is limited, please indicate if you intend to attend in person (post to this event).
Jim will issue a programming challenge to hone or improve your coding skills.
Mark will share his 3D printer, octoprint, experiences.

Interested in feeding your data to more than just Flightradar24 or Flight Aware? Unsure which feeder to install first? Confused by which dump1090 fork to install?
This presentation will demonstrate installing one feeder on your Raspberry Pi and then discuss the quirks to setting up the additional feeders (ADS-B Exchange, AirNav RadarBox, OpenSky Network, and Plane Finder) so that they all play nice together.
We will be conducting Virtual Meetings for the next few weeks using Jitsi, a free video-conferencing system. Please use Chrome or Chromium for the best experience, or download one of the pre-built clients: https://jitsi.org/downloads
Due to the current situation @ March 14, 2020, in-person meetings have been suspended until further notice. Please do join us on Slack or at our online learning sessions using Jitsi. Write to hello at vicpimakers.ca for invitations and information.

1) Hack Challenge, by George Modify a window alarm to be a useful or entertaining device. Window alarms to be supplied free March 14th, one per attendee.
3) … bring projects that you want to share or need help with… If you like, email a description to be added to this page.
It is fun to repurpose battery powered consumer products. For instance, here is a Leak Detector made from a window alarm. The article includes the window alarm schematic.
And George made a bike theft deterrent alarm with remote radio alerting from the same window alarm.
In normal operation, the window alarm senses separation from its external magnet via its internal reed switch and feeds its piezo disk with an oscillation. The window alarm runs on 3 button cells and draws no current when the reed switch is open. There is also a slide switch to enable/disable the alarm.
Here is a photo of the circuit board: The OUT signal from the 8 pin oscillator chip is a 10V DC wave, pumped up by the inductor from 5 volts. A voltage divider can be added to lower this chip output signal to less than 5v to feed another device.
Deid successfully connected a 50 light string of addressable LEDs to an ESP8266 to cause the lights to light and change colour and move and …
Deid created the following patterns:
Primary
Random
Web Safe
Follow
Lead
Random On ***
All On
All Off
Rainbow
Moving
Colour
Christmas
Rainbow Group
Dual Colour *** *** Shown in the images
The ESP8266 C code to do this can be found here. Deid makes no representation that the existing code is good. In fact he knows some of it is not. Feel free to fix.
The challenge is to add more patterns and the code to implement the patterns. If you send Deid the code he will load and try the code. Unless someone comes up with a better way for folks to test remotely.

Interested in the basics of computer networking? Want to know how your packets get from here to there? Don’t miss this Introduction to networking presentation which will answer the following:
Why do we need Ethernet anyway?
The basics of IPv4 & IPv6
What happens when a packet is routed
Some basic SOHO network topologies
Bring your own coffee, and we’ll see you on Jitsi on Saturday!
A Special Interest Group focused on computer networking. Building networks for Today and Tomorrow! Half of the meeting is education, or presentation. Half is sharing, and problem solving. Bring a laptop with Wireshark installed: We’ll be running a hands on workshop using iptables/ip6tables/bpf (BSD Packet Filter) Thursday, February 20, 2020 6:30 PM to 8:00 PM Q-CollegeSuite 303 771 Vernon Ave · Victoria, BC
Using Nexus DR-S hat on your Pi to control your Amateur Radio. Nexus DR-X (aka: DigiLink) is a digital radio cross patch that allows you to link the Raspberry Pi sound card of your choice to nearly any amateur radio transceiver to enable perfect digital data communications.
The Buster RPI image includes a host of Ham apps and a simple dialog box that makes updating and installing your favorite programs easy. Deid’s presentation notes are here.
Victoria PiMakers needs your input to plan presentations. These 10 questions should take only a couple of minutes. Your email address will NOT be shared.
In this session we’ll look at basic network scanning technologies such as ping, netcat, and nmap. Please bring a laptop with wireshark, netcat, and nmap installed.
