As if they didn’t have it all covered by now here in Cali…
Graffiti vandals beware — there’s a new sheriff in town, and you won’t ever see him.
Broadband Discovery Systems, a two-year-old company based in Scotts Valley, has developed a series of devices finely tuned to detect the sound of an aerosol spray can from as far as 35 feet away.
“I despise graffiti,†said president and chief executive Cory Stephanson, who worked with a team of engineers to build the device aimed to stymie graffiti vandals.
Stephanson and vice president Michael Neely discovered that $22 billion is spent every year in the United States dealing with graffiti, and they think their latest innovation will help.
The device, nicknamed “Project Merlin†after Stephanson’s son, has intricate sound recognition features that are tuned to detect only the specific sounds an aerosol can makes. When the sensor detects the sound of a can dispensing, it uses cell-phone-like technology to send out an alert.

I remember finding some videos on YouTube a while back showing this one crazy guy who slides out of the windows while the train is moving and jumps on top and screws around, graffin all the while. I think it was in the Dirty Handz videos. Crazy stuff, I’ll post them if I can find them again. I’m pretty sure this isn’t the guy, but could be related somehow. Anyways, on with the news.
