This is just awesome !! :D

waiting to see more !!

I wanted to ask if you could post a little more about you mini-sd card connection,

what libraries to add with it, and what should be used in the code.

Thx in advance.

Yup, just install the experimental 0.9 version. You'll notice there's a new "USB Type" sub-menu within the Tools menu. Use it to select "Disk(SD card) + Keyboard". Then just upload like normal, and if the SD card is connected properly to the 4 pins plus power, it'll show up as a USB disk. There's also a "Disk(Internal) + Keyboard", which uses the remaining memory in the Teensy as a disk. On Teensy it's read-only, but you can pre-populate it with files by putting them into a certain directory. On Teensy++ the internal disk is read-write. SD cards should always be read-write, unless they've been specially write protected, which is very rare.

Not many people try 0.9, maybe because "experimental" sounds pretty scary? About the worst case is you'd have to reboot, delete everything, and just unzip a fresh copy of Arduino and install 0.8 again. But I believe you'll have a much better experience than that. Please do give me some feedback either way.

Eventually I'm going to add a filesystem layer, so you can access the disk from your Teensy-based programs. That will probably need a lot of testing! You can also see my to-do list on that page. If there's anything I missed, now's the time to speak up. When 0.9 become "official", it'll probably be a 3 to 6 month period until 1.0 is made.

Is this due to a hardware limitation of the teensy, or could it eventually be possible via code to get write access on the teensy 2.0?

I've not done much work with the SD yet, best ask Paul. My understanding is you will need the experimental version of Teensyduino http://www.pjrc.com/teensy/experimental.html
