I am planning out my at home winter break project since I'll have not much to do during the break. I'm planning on making a Portal Turret (turret from the game of portal. if you've never played, then you're missing out). One of the parts of the project I'm not familiar with is getting the damned things to talk. The portal turrets are memorable because of their odd voices and choice of words. If I can get the sound waves/mp3 files from the game, what can I use to just play the sounds whenever I want?
Other than that I've got it planned out - hobby servo to rotate the body, one servo to open their shell, cheap laser pointer, infrared sensors to use as motion detection. The other tough part will be figuring out how to make the turret fire nerf guns but thats down the line.
