As of yesterday, we started to run the unit with a pencil lead chucked into the drill head. This is to begin testing the pattern configurations. What is drawing was my first attempt at an “estimated” sine wave. There is obviously more work to do, but I’m pretty excited that it’s gotten this far! Click on the image below to see it in action. You may want to turn down the audio, there was a movie trailer being played on the machine when I taped this – sorry about that.
