Let's Make Robots!

Using a Toy Speaker

First I just have to say that this site deserves a lot of credit for getting me into robotics. I only had an inkling of an interest in robotics until I built the "My First Robot" so props on that.


To my question though, I found this cheap santa toy for a dollar with motors and a speaker for saying some santa related phrase and I want to try to make the speaker play either from an ipod or some sort of microcontroller sound module or something. How could I do this?

Also on the speaker it says GW 8 ohms 0.5 watts.
