Back in February of this year, Vayyar Imaging announced the launch of Walabot, a new type of device that works with your smartphone in order to allow for in-wall imaging. They created the Walabot division to offer their consumer devices for 3D imaging. The Walabot DIY has a compact footprint much like a mobile phone. Considering it is meant to work with your mobile phone via USB OTG, the size and shape is one of the key features to it being a useful tool in your box.
