Thanks for the response.

Thank you for the response. I am going to try and run everything off of a 9V lithium battery but it may be too much current for it. If that is the case I will have to get a battery pack or just run from a 12V source. I think I am going to power my circuit off of the VIN pin with an external LM340 5V regulator. This way my external circuit won't rely on the Arduino's regulator.

What is the max current that the Duemilanove's 5V regulator can source without the risk of overheating? I want to power some stuff off of the 5V pin and it will bump the total current the regulator is sourcing to a little over 200mA. The regulator itself is a MC33269-D that is rated for 800mA, but I am not sure how it will fair with the way it is mounted on the Duemilanove with what looks like a fairly limited stock heatsink.

But does it read/write FAT? Will it be added to the official Arduino library page?

Is there any hope on getting the read from SD to work?
