An answer to the need of the Hamsci Personal Space Weather Station Project for a low cost easily deployed 3 Axis magnetometer for earth surface geomagnetic field measurements based on the PNI RM3100 magneto-inductive magnetometer module for $31 in single quantities, compatible with Raspberry Pi class Single Board Computer data interfaces. Development of an inexpensive housing using off the shelf (OTF) components and a simple temperature stabilization technique and recommended interface will be discussed. Magnetometer system data will be compared with an appropriate Intermagnet site demonstrating the ability of this low cost instrument to achieve near 5nT resolution and noise, opening the potential for a diverse network of Citizen Scientist sites contributing data to better understand Earth's geomagnetic field.
