Editing CatchAllSensor

The CatchAllSensor project aims to build a small free software free/open hardware device for use in detecting movement when attached to a computer system.

The basic design is to make the cheapest sensor possible and will likely be built from the following parts:
* [http://www.sparkfun.com/products/9147 AVRStick]
* [http://www.emartee.com/product/41841/Arduino%20Mercury%20Tilt%20Switch Mercury Tilt Switch]

Optionally, though nearly tripling the cost it, may be nice to add an Accelerometer and a case:
* [http://www.makershed.com/ProductDetails.asp?ProductCode=MKPX7&ampClick=19209 Memsic 2125 Dual-axis Accelerometer]
* A small 3d printed case

Another Accelerometer config (and cheaper than the one above), would be:

* [http://www.ftdichip.com/Products/ICs/FT2232H.htm High speed USB/I2C UART]
