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.

six node time lapse oops again

It messed up while drawing the six node figure also and I stopped it part way through. I haven't drawn it right yet.

five node time lapse oops

I went off to Dairy Queen to get supper while it was drawing. The string caught on the knot in the bobbin and wound up when it thought it was unwinding. There are a couple of frames of my wife putting the pen gondola back on the front of the board.

I redid it so you can see what it is supposed to look like.

I'm experimenting with time lapse using the camera on my laptop.
