FIREFLIES is an interactive light installation at Capilano Suspension Bridge in Vancouver, BC. It is made up of 10,000 individual LED+sensor 'fireflies' in the pacific rainforest. I worked on this as part of my role at Tangible.
I was technical lead on this project. I also prototyped the IR flashlights, prototyped firefly behaviours, and planned and built the power distribution. Because it is installed for multiple months at a time, outdoors, in the coastal rainforest, in the winter, there were some pretty serious water ingress challenges. It seriously poured; and the water was full of minerals after running through the canopy. I learned many techniques for protecting electronics from water and corrosion.
The pictures here show prototypes and installation.
