Steam


This took just over 6 hours. I might be able to speed it up to 4 hours.
Here is a speedup of the time lapse, just under 2 minutes.

Here is the regular speed time lapse, over 10 minutes.

harmonograph

I tried simulating what a harmonograph would draw. The harmonograph is an old mechanical drawing device that predates the spirograph by about 100 years. Here are some links explaining it.

valentines 2014 revisited

This took almost two hours to draw. Condensed down into just over three minutes of  video.
This is based on a stamp that Stampin Up used to sell. It was scanned, traced, stippled and turned into an SVG file. Then I extracted the data with a text editor, tweaked it with Excel and put it into the arduino. It draws a six dot wide circle at each point. There are 4810 circles.

about as good as it gets

I switched to a new pen because the other one ran out of ink. This one is thinner, more like a pen than a marker. It draws a finer line.
Here is the timelapse. Photos taken every two seconds with my laptop camera. Output fifteen photos per second.

tried to fix it

I swapped the SIN and COS functions around. That had the effect of rotating the picture a quarter turn and drawing in the opposite direction. I didn't have time for it to finish last night but what it did worked pretty good. I will try again when I have more time and film it.

six nodes one hundred rounds timelapse

I stitched over 3000 photos together into a little over three minute video.
It messes up part way through but is still mesmerizing to watch.

six nodes one hundred rounds

I tried this one last night. As it moved down on the left side the pen would kind of stick to the board and didn't slide nicely. I think at one point it stuck enough to cause the bobbin to lose a wrap of string. All the lines after that were out of place. I did have the laptop set up to take a picture every two seconds. I am working on pasting them all together into a video. Any suggestions on good software to do that would be appreciated.
It may be time to move up to more powerful motors and a better motor driver.
