Abstract: A flexible device mounting kit allows to securely attach a sensor or another device to an arbitrary surface, including a surface that is very uneven. The kit includes a scaffolding assembly which includes a scaffolding guide and scaffolding teeth attached to the guide in a way that allows some of the teeth to move relative to the guide when the bottom of the teeth is pressed against uneven surface. When the assembly is pressed against the surface, the positions of the teeth adjust, forming, together with the surface, a cavity into which a gluing compound can be filled. A device mount to which a sensor (or another device) can be attached is pressed into the gluing compound before the gluing compound solidifies. As the gluing compound securely connects the sensor mount to the surface, the device can be securely placed within the mount regardless of how uneven the surface is.
