  • increase radio range - 151MHz radio
  • handle fast or adaptive sampling in its buffer
  • increase buffer size - more eeprom
  • change to MSP430F5xxx to reduce component count and increase RAM
  • move to an OS - currently Contiki see Contiki for probes
  • use bolt-together enclosure like the Tijuana version with Phil's mods
  • circular probe PCB and separate RF pcb with sandwich of batteries
  • need sleep current of a few microamps max.
  • low noise, low sleep power PSU - see GW11-psu
  • range of probe Sensors

Sensors will include accelerometers read over a period of time in order to read not only angle but any accelerations. Plus a good conductivity sensor and sensitive temperature sensor (thermistor).
