Wireless mouse as cheap link to PC for arduino

Has anybody successfully used hardware from regular wireless mouse as a cheep alternative for sending data from Arduino to PC?

I've read somewhere that encryption is really weak (XOR-ing with single random byte determined at the beginning of the session). I know the range is not very long, but it can be very useful, and first comparable solution is 2-3 times more expensive.

I see two issues here.

First, the mouse sends it's data to a driver on the PC, so you would have to hack into that to get to the data.

Secondly the mouse is made to send buttonclicks and (delta ?) X / Y coordinates only (and a scroll wheel move maybee), so it would be of limited use unless you could change that somehow.....

do a search on ebay for 433mhz (I think) RF link modules. You can get em as cheap as $10 a pair delivered, if the docs are to be believed, they can function as a virtual-wire serial link with no further modification.

I’ve not bought or used them, but looks promising. Sure Electronics sometimes has sold them (think sparkfun has too?) so I think the modules themselves are probably legit…

Check out the JeeNode for an example of an Arduino clone including a serial data radio link at 915 MHz, for about the same price as a standard Arduino. Data rates up to 115 kbps, range up to 100 meters. http://shop.moderndevice.com/products/jeenode-kit

They are using the HopeRF RFM12B module: http://www.hoperf.com/rf_fsk/rfm12b.htm

Sparkfun sells it for $6.95 although they are out of stock right now. http://www.sparkfun.com/commerce/product_info.php?products_id=9582
