mount ISO files instead of burning them to a disk

I wanted to install a piece of software on my computer that I downloaded from the internet as an ISO image. I knew those are files that one usually burns onto a CD and then installs from there; I have done my fair share of linux installs like that.

But what if I don't want to burn the file onto a CD? Surely there are ways of making the file usable without wasting a CD or DVD.

And of course there are:
Virtual CloneDrive works and behaves just like a physical CD/DVD drive, however it exists only virtually. Image files generated with CloneDVD or CloneCD can be mounted onto a virtual drive from your hard-disk or from a network drive and used in the same manner as inserting them into a normal CD/DVD drive.

great! What I needed and you can find it here:

Playing an mp3 file with the VS1053 arduino shield

Here's the code that plays a "hello" on speakers connected to the mp3 shield for the arduino made by sparkfun:

download the pde file from here.

This code is a port of a code made available by VLSI (the manufacturers of the VS1053 mp3 chip), available on their forum for the AT89C51ED2/RD2 microcontroller.
Have fun. Still working on getting the shield working with a VLC stream, slow but getting there and this port is part of way to get there!
PS: note that the Tx and Rx pins must be pulled out of the mp3 shield so that they do not connect with the arduino board.
