This Scanner in the Dirt Captures All That's Going on UndergroundCasey Chan6/24/16 2:27pm135EditPromoteGo to permalink Dirt is boring. Soil isn’t fun. Who cares what’s happening down there. So I thought. Josh Williams changed my mind with his SoilCam, a waterproof scanner that’s controlled by a Raspberry Pi. He places it in the dirt so we can see everything that’s happening underground. It’s so alive.
