Stupid Simple Arduino LF RFID Tag Spoofer

Wednesday, April 14th, 2010

on Instructable an Arduino spoofing of an RFID signal:

RFID tags are all over the place.  They’re used in building access control systems, passports, inventory tracking . . .   This instructable will show how you can use an Arduino and a few simple components (wire coil, transistor, capacitor, resistor) to make a device that can spoof an 125 KHz (low frequency) RFID tag.  This is version 1, so there are many enhancements that can be made, but this version is stupid simple, yet it works.  I did this in a few hours without much previous knowledge of RFID and without any fancy equipment (like a radio tuning hardware or an oscilloscope . . .I guess an oscilloscope is fancy, I need to pick up one of those).

LDR+IR range sensor

Friday, April 9th, 2010

from [jeanbaptisteparis] on flickr

a little project for my lab, a mouse that knows at which distance you’re from it. We would like to explore if this information could be relevant for the system e.g. to highlight the cursor when you approach your mouse or to tell background operation to interrupt in order to release CPU for interaction…

he is using a LDR for the 0 to 4 cm and a Sharp 2D120 IR range finder for 4 to 50 cm. The arduino code on the flickr page.

Review: X10 Home Automation with Arduino

Tuesday, March 2nd, 2010

After looking here and there, I could find this Sept ’09 article found on geekboy. As the site was down I found it googling on willshouse‘s blog. anyway. Mike Parks’ example about simple X-10 triggering via RFID using the free SSH/telnet client PuTTY.

In this example, I control 1 device (on X10 circuit A, device 1). I initally turn the device off. When the RFID tag I am looking for is read, I turn the lights on. Next time that tag is read, I turn the lights off. I acknowledge various changes by providing feedback to the user via blinking LEDs and serial comms to the PC.

code ready.

New home monitoring setup – part 1

Friday, February 26th, 2010

The second post of the week about open source home monitoring.
Part – 1 means that for now you can read just a long list of pieces of hardware.
But then: home monitoring and X10 are the more interesting projects around.

waiting for part 2!

Arduino Pachube Library

Wednesday, February 24th, 2010

As I read on this blog post by Jose Anes, he has been working on a while on the Arduino > Ethernet shield > Pachube communication, to achieve “a Pachube manual update client on the arduino that pushes EEML XML format to Pachube directly, without a PC in the middle”.

If someone has a better library, please let me know where to find it.  Here is a link to the code I am using to accomplish this purpose.  So far it is working well enough.  Some interesting points:
  • I had to print directly to the stream (ethernet in or out), because creating an EEML XML string was too much for the small memory of the Arduino.  Direct writing as a stream solves that.
  • I still want to avoid the reset every time it uploads to pachube (took that from the pachube CSV example).

The code: 20100218-pachube
