The circuit is completed but the effect is minimal. I think I mix the water too much or the powder is too low. It’s hard to make it right however, I can make it happened in the final project.
Challenge: The mixture is very hard to get it right. As I do not have the basic knowledge of watercolor or brush.
Experiment with Flexinol
I like how the spring can go back to its original form. This is pretty fun when playing with it. I failed to work on the first try because of the voltage.
Challenges : The calculation of the voltage is a little complex for a beginner.
