Hacked Gadgets went to Island Tech 2009 which was on Vancouver Island British Columbia Canada to check on the technology that was being demonstrated. Contech was there showing some of their products, the Scarecrow was by far the most interesting. It isn’t a new product but the way it was hooked up for demonstration was interesting. There was no source of city water like there would be in your back yard so they had a sealed dome around the sprayer and a pump that would produce the pressure needed to operate the device. Simple yet effective. This is a great system that can be mass produced however I still like the WaterHobo that we featured a few years ago , too bad this system would be costly to produce.
