Introduction to Scratch. Scratch is a block-based visual programming language.
Be sure to HAVE a LAPTOP, as these are hands on sessions.
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 the event on meetup here).
Overview of IDEs for programming your embedded devices.

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:
Random On ***
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.
