Where does the Javascript run, anyway?
summary
Built a cat GPS tracker that puts a GPS logger on collar and an Arduino Pro Mini for local sensing, with a BeagleBone by the cat door that pairs over Bluetooth to pull logs and maps them (Mapbox); battery life about 16 hours, Bluetooth pairing causes the most trouble. Use Johnny-Five + Firmata to write JavaScript on a host (Arduino is tethered), or move to a Linux board like Raspberry Pi ($35) or BeagleBone Black 65 pins to run Node locally. Espruino/Tessel promise on-board JS.
