My idea for this project was to bring to life a tiny Christmas tree. Winter season is here to stay for a couple of months but Christmas trees will join our households just for a couple of weeks. I was planning on keeping the tree alive by interacting with it.
This is the circuitry, heating circuit + swatch + breathing tree +9V battery.
Detail of the breathing movement when applying current.
After some failed attempts this version kept the movement quite subtle but smooth. However, the connection of the Flexinol wasn’t strong enough. So I had to reinforce it.
