* '''Bare Bones Breadboard Version'''


If you just want to knock something up quickly and cheaply on a breadboard it can be done for about £12 with a stripped down version. It can be programmed and powered using the FTDI serial cable - becoming a standard bit of kit for talking to microcontrollers. Ken has prototyped this and it is successfully sending temperature readings up to Pachube. [http://www.pachube.com/feeds/8729 Pachube Feed]
