Weekend Project: Connect a letterbox to Jabber with XBee

May 16, 2010 at 19:05 (Electronics, linux) (, , , , , , )

As i promised this is my first XBee Project. I just needed a more or less useful application i can “test” the XBee’s in a real environment.

It is in my nature to do crazy things, so i thought it would be really cool to have a notification Jabber Message to my Phone when someone put some letters for me in my letterbox. Here it is ;)

01-08-2010 Update:
The FTDI Chip gives me A fscking LOT PAIN more to come in the next Post. DO NOT USE IT :)

This is my Setup:

  • XBee “Coordinator” API Mode connected through a FTDI USB Chip to a linux box
  • XBee “End Device” Interfaced with an Atmel ATTiny13v power by two 1.5v AA Batteries
  • Perl XBee Module API.pm from Thomas Jager
  • Jabber Perl Modules to enable sending messages
  • Siemens S685IP DECT Phone that can recieve Jabber messages

Before you read further you should note that i flashed the ZIGBEE firmware (XB24-ZB) API on my XBee’s because i don’t want to miss the mesh feature.

This Setup now runs with 2x Alkaline Batterys in the End-Device for 4 weeks now, and is still running!

Recently, well 1 year ago, i readed in The Make Zine about a Project called “The Brain Machine”.

This is a modified Atmel circuit that claims: “Get altered states of consciousness with this microcontroller-driven sound and light device.” by Mitch Altman.
