CNC Light Painting: Vast Improvement Using a Remote Trigger

Up until now, my light paintings have been shaky or very small.  That all changed when I bought a remote trigger from Amazon (for around $5 with shipping!).  I’ll give more information about this little device on this in another post, but for now, here are my results:

I was quite happy with how the paw details turned out considering my “Y-axis” canvas was only 2″ high (see my other posts for a better explanation).  The third CNC light painting was from a video game that anyone should recognize, Pacman!

  3. Very interesting technique for taking pictures. I’m looking forward to seeing some even more evolved designs – Multiple lights, colors, 3D!

    • Thanks! I’ve meant to do more of this stuff, and hopefully I will, but it seems there’s always some other interesting project to work on! Glad you liked it!
