What happens when you strap 48 Raspberry Pi cameras together with nearly half a kilometer of network cables? You get your own bullet time capture rig.
Originally inspired by the unique film effect of the Matrix and an old BBC documentary called Supernatural: The Unseen Powers of Animals, the owner of PiFace decided to try re-creating the bullet time effect himself.
To create the rig they’ve taken 48 Raspberry Pis, each with a PiFace controller board and the standard camera. The controller board allows the Raspberry Pi to be used without a keyboard or mouse, so all the network cables have to do is send a simple code to each pi in order to take the pictures. A simple laser cut wood profile is used to snap them all together into a giant ring.
While 48 Raspberry Pis is a lot, they think this is a reasonable project for a classroom environment — besides, how cool would it be to go to school and film your own bullet time stunts?
