The Seed Eater project arose from research into how fast winged seeds (samaras) fall, in order to predict how far they might travel across a landscape, and hence understand how quickly populations of invasive trees might spread. In the past, ecologists have measured the terminal velocity of seeds using stopwatches and lasers, but stopwatches are inaccurate, and lasers are expensive.
Enter stage left, Pieter the Seed Eater; a low-cost device fitted with a Raspberry Pi computer and camera that captures a sequence of images, assesses which timestamped images contain a falling seed, and then calculates how far the seed fell, and hence how fast it was travelling.
