Light painting with a string plotter

[Matt Bell] sends a shout-out to Hackaday by creating a light-painting of our logo with his string plotter. He starts off by setting up a pair of stepper motors which each have a spool to wind and unwind a string. The plotter is made by suspending a stylus between these two strings. In this case, he’s using a wireless LED board (seen above) built from the remote control receiver/transmitter from a toy car. The link above is part of a Flickr set from which you can get the whole story by reading the captions of each image.

After the break we’ve embedded a clip of an in-progress light painting. You can see there’s some oscillation of the LED unit that makes it a bit less precise than the CNC light painter we saw a couple of weeks ago. It seems like string plotters usually don’t have this issue if the stylus has something to helpĀ stabilizeĀ it. We wonder if a piece of acrylic would help get rid of the shakes?

      1. Yes, please do create a build page. I’m interested in how you’re interpreting g-code with an Arduino. If you do write this up, please include some of the references you found helpful in creating this. Thanks for making something cool and sharing it with us all.
