Heating my thermochromic ink

December 7, 2008

I quickly sewed some copper to the back of one of my thermochromic ink  samples. The copper has a low resistance. In the video I connected the copper to 9v and 5v. The 9v activated the ink too fast. I think 5v will end up working well. More testing is needed where the copper is fixed more permanently to the back of the inked area.
