I got some ATTiny and now need to transfer the program from the Arduino IDE to the ATTiny without a programmer.
The solution is, just make your own programmer shield. Based on this tutorial http://hlt.media.mit.edu/?p=1229 I created my programmer shield for the Arduino Duemilanove. It's not pretty since it's just a ugly board out of my box but it works. Preparing the Arduino duemilanove according to this tutorial and then hook up the ATTiny into the header pin socket, open your sketch and click upload. Done!!!
