While the project has largely languished lately, I reimplemented a sensor with similar capabilities to Project Seaglass with the goal of a lower BOM cost and easier purchase - the particular Telit module they used is discontinued and hard to obtain. My BOM is around $160 and could be lowered. See here: https://github.com/jcrawfordor/cellscan
