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.
10:00 AM to 12:00 PM
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:

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 covering the basics of packet capture, and seeing what is actually on your network.
Jekyll sites can be connected to cloud-based CMS software such as CloudCannon, Forestry, Netlify or Siteleaf, and Github enabling content editors to modify site content without having to know how to code.
Here is the link to Gordon’s fine presentation.
