===== main goals =====

There is few sub-project in with various progress.

  * sonde hardware / software
    * [[hw|PCB connectors pinout, IC list and description]]
    * [[pcb|Reverse-ingeneering PCB]] (PCB schematic, component values)
    * [[cpu|Reverse-ingeneering CPU]] (pinout, building blocks, instruction set)
    * [[Firmware]] dumps and content analysis
  * telemetry
    * [[telemetry_receiving]] - demodulate and decode data frames
    * [[telemetry_decoding]] - frame structure, data evaluation
  * local control
    * [[eeprom_mgmt]] - control your Vaisala with Arduino!
