This isn’t your typical home automation project; who turns a blender on remotely? [Brian Gaut] did, when he rigged his blender and a strobe light to scare his cat off the kitchen counter. To be fair, we’ve linked to this project before on Hackaday—twice actually—but neither the article about relays or the related cat waterwall article actually talk about the BlenderDefender, and that’s a shame, because it’s pretty clever.
[Brian] began by installing a DCS-900 network camera on the wall near his kitchen sink. The camera monitors any motion on the counter, and once it detects something, a networked computer starts recording individual frames. This security camera setup isn’t looking for criminals: [Brian] needed to keep his cat away from a particularly tasty plant. The motion detection signals an X10 Firecracker module to turn on both a nearby blender and a strobe light, provoking some hilarious reactions from the cat, all of which are captured by the camera.
