Vicpimakers and Others will be taking a summer break in July and August. We will be back in the fall with an awesome lineup of talent and gear.
Linux meetup will continue throughout the summer on the first Saturday morning of July and August. All meetings are virtual. https://meet.jit.si/vicpivlug
NetSig will continue too! Fourth Thursday of the month. https://meet.vinnythegeek.ca/netsig
9:30-10a Cocktails & Conversation
10a Presentation
Virtual Meeting: https://meet.vinnythegeek.ca/vicpimakers
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.
ADS-B Exchange: https://www.adsbexchange.com/
AirNav RadarBox: https://www.radarbox24.com/
Flight Aware: https://flightaware.com/
Flightradar24: https://www.flightradar24.com/
OpenSky Network: https://opensky-network.org/
Plane Finder: https://planefinder.net/
Here is the video of our virtual meeting:

We’ll be conducting this meeting virtually using Jitsi
https://meet.vinnythegeek.ca/vicpimakers
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.

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.
Or the piezo can be used as a microphone, providing about 100mv into a very high impedance input
In May we can show what we achieved.
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:
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.
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 have a LAPTOP, as these are hands on sessions. https://meet.vinnythegeek.ca/vicpimakers
