I updated the Transparent Terminal sketch to work with arduino 1.0, using the SPI library, and I cleaned up the initialization so it looked better (to me, but maybe not to you!). You can try it out: www.holdentechnology.com

kev: What’s the recommend resistor for running just a basic temperature sensor?
The datasheet says it will run on 400 uA to 5 mA. The datasheet data is based on a 1 mA current.
I tried it with a 5V suppy and a 10k resistor, which should give 500 uA (neglecting the diode), but the voltage was very low. A 5.1K (for 1 mA) worked fine.

What voltage regulator are you using? It’s not clear from the schematic. Mine powers off at about 15V (when I’m charging my 12V battery). I’m considering moving the power to the regulator from Vin to the 5V line.
I bought one of these to send twitter updates for a sensor project I’m working on. If anyone wants to they can check out my code (based on the sparkfun tutorial):

Also, since SS for this device (arduino pin 8) is not the default atmel SS pin (arduino pin 10) be sure to set pin 10 as an output or hold it high. If pin 10 is an input and low the master spi operation of the atmel is stopped and it switches to slave mode. This might be why some people have only been able to get soft spi methods to work.
I’m glad you’re updating the voltage conversion.
I got it working with voltage dividers and the sdfat library, see: http://www.holdentechnology.com/micros2/arduinos/60-sdshield
