Martha Vader - A MakerBot sings the imperial march and makes a Darth Vader Head

We got black ABS plastic into the MakerBot store. Now you can make black or white objects with your MakerBot. We had this plastic custom manufactured and it's beautiful, extrudes great, and has a really nice silky sheen to it. Marius and Philipp of the Metalab in Vienna take responsibility for this wonderful robot stunt. They have been visiting and they set up the MakerBot named Martha Vader to sing the imperial march and make a Darth Vader Head. The sound is coming from the stepping of the steppers. Each step of the motor creates a square wave and when you line them up at the right speeds, music is possible

The march was great. Brought back memories of my misspent youth writing 6502 assembler routines that did little but loop and poke the speaker memory location to make square wave noise.

Uh, oh, here comes my boss.

"Yes, sir. Good to see you, sir. We're making good progress, sir."

"You may dispense with the pleasantries, Commander. I'm here to get you back on schedule."
