Portal - Still Alive. Played by 16 Stepper Motors

Stepper motors play the MIDI version of Still Alive (by Jonathan Coulton and Ellen McLain) from the Game Portal. A Python script sends the midi data to an arduino that controls the stepper motor. The speed of the motor determines the pitch of the note that is audible. 16 single recordings are then cut together.

The percussion motor is such a neat idea and really pulls the whole thing together. Well done

People of RUclips! Get this to be more popular so that the poster can actually get 16 seperate motors & take this to the next level!!!

I gotta hand it to GLADos for making the most passive-aggressive ending lines despite everything

The reason Science is so fun.
It's never about Why, it's about Why Not?

[@bitwize]

Go ahead and MARRY safe science if you love it so much!

This is really amazing. Think you can do Cara Mia Addio next? That song's built for stepper motors, but no one have made it yet.
