The next step.

This one took over an hour to draw.

Here is a video.

Performance art.

Here is the latest drawing.

Since this is really a form of performance art the pleasure is in watching it draw more than looking at the finished picture. I am working on uploading a video.

Some improvements

I raised the voltage that I run the motors to 12 volts. They run hotter but I don't think they are too hot. That let me speed it up about three times what it was. I tried some things to explore the limits and characteristics of the system.

Then I went back to some old favorites and updated them to work with the LEDs and switch that I added.

They look a lot better with the 12 volt steps.
I am working on some of my other old favorites.

stages 0 through 8

Here are the stages of the dragon fractal with curves. I like the individual stages better than the parade.

 

 

 And here's a short video. The battery died after only a few seconds.

parade of dragons

I got it to do stages 0 through 8 all in a row.

I added some LEDs and a "switch" so I can have it tell me to center the marker, erase the board, and press the button. Then it will wait for me instead of just giving me a minute to do those things whether that was long enough or not.

I am going to order the new version of the Arduino that has lots more memory so maybe I will be able to do more stages. When I get that I will mount it to the frame it isn't all just hanging.

Dragon fractal with curves.

I got the curves to work on the dragon fractal.

Still needs a little tweeking but it is getting there.

Dragon fractal.

I'm working on the dragon fractal in Arduino that I had done in QBASIC.

I want to do it with curves instead of sharp corners. It looks much cooler that way.
