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.

Intro to Pi & Others is a 4 part series of short monthly sessions to help get you up and running with your Pi or Other (embedded device). It is a structured hour-long session where you can ask questions.
Please bring in your Pi, HDMI cable, and power supply. All other equipment will be provided.
This is a four-part series with each session building on the previous sessions, where Pi basics of software and hardware will be explored. Read More
VicPiMakers will be supporting Projects in 2019. What are Projects? Deid’s pond is a project, for example. If you have a project idea, bring it in and we’ll see how we can help you complete your project.
