External battery scheme

IMAG0040Peter and James modified 13 sensor motes for the new external battery scheme, and more motes will be modified soon. These motes will replace a number of motes in the field Olinda that suffered complete battery depletion. Effective battery management is one of the most challenging aspects of the practical network deployment. Peter also made and tested a prototype of the waterproof battery case and a third-party USB charger (see the photo below). Replacing batteries can be highly time-consuming. The new scheme should dramatically streamline vital battery maintenance, allow USB-charging of batteries at the base, with hot-swapping of charged in the field. Further battery kits will be implemented soon, following field testing of the new scheme.
