Arduino as wi-spy

Former Member over 13 years ago

Anyone who's used an arduino as a wi-spy device?

I have the Ethernet version, but maybe anyone with the Xbee Shield Wireless Module can let me know whether they've tried it?

i am very interested in your project about arduino work like wi-spy.

Hi - I hadn't heard of Wi-Spy before. Is this product at ThinkGeek it?

http://www.thinkgeek.com/gadgets/electronic/c240/?cpg=clrss

Tracks all radio activity from Wi-Fi, Cordless Phones, Microwave ovens, Zigbee, Bluetooth, or any other 2.4 GHz device.

You raise an interesting idea for an Arduino project. I would imagine though that a more generic radio than a XBee or Wi-Fi module would be needed to survey the spectrum as described, but I don't know that much about RF. Maybe software defined radio (SDR) could play a role here. Although I would imagine that would require an FPGA solution or at least a microcontroller with more horsepower (maybe like the Beagle Bone?).

Jeri Ellsworth did a video on SDR's awhile ago: http://www.element14.com/community/videos/2925/l/Direct-Conversion-Receivers---You-Only-Live-Nine-Times

Cheers,

Just found this:

DIY-Spy
http://tim.cexx.org/?p=646

This looks very promising:
As proof of concept (and a cool toy for anyone who has one of these lying around), I have implemented a working Wi-Fi spectrum analyzer on TI’s ez430-RF2500 development kit ($50), a 2-part USB dongle which consists essentially of a CC2500 radio strapped to an MSP430 low-power microcontroller (detachable bottom half) and a USB interface which enumerates as a virtual serial port (top half). The top half doubles as a standalone MSP430 programmer, so this kit is a great cheap way to get started playing with them.
