It took me a lot longer than I expected to get this print out. In theory it was really straightforward, take my turtle image and feed it through similar code as what I used to make the jellyfish, but... I recently added a MOSFET into my print system so that I can control the anodizing current by pulsing that (instead of print speed/voltage), but it led to a ton of EMI issues messing with communication with the motor controller. After changing my grounding paths many times and receiving a few fun 200V shocks I just re-wrote my controller code to be more fault tolerant, and that seems to have done the trick!

New style! Kaleidoscope, medium is still anodized titanium because I'm a one trick pony :D

This has been a fun one - I was testing using more traditional pen plotter techniques (wiggly lines) to drive color instead of dwell time. It's really interesting how it comes out, the way the anodizing affects neighboring lines create a bit of a natural averaging that makes the whole thing look 'higher resolution' than the same thing drawn with just ink. Here's a closeup of the lines - pretty cool!

New print! This one played with a new technique. I noticed there is a speed that makes resonant vibrations in the pen plotter. This entire print runs at that speed, giving the colors some texture from the vibrations. The color variation comes from repeated passes over the same areas.
