• The SOLO is based on the Raspberry Pi model "B", with a really friendly power consumption of approximately < 2 W.
• Inside the box there's an SD card acting as the device's hard disk. It is mounted in "read only" mode, meaning:
  • There's no problem at all unpowering the unit—the SD card will never become corrupt. It is only written, for a very short while, after configuration changes or a system update.
  • It will take a while (minutes) after powering the SOLO for it to retrieve the correct time and date—please be patient.
  • The SD card will not "wear out"; these cards have a limited number of write operations, so being read-only extends its life almost indefinitely.
• You can get the last reading from the CloudWatcher easily, to use in a program or a personal web page: http://aagsolo/cgi-bin/cgiLastData
• Similarly, you can get the historical data for up to 48h: http://aagsolo/cgi-bin/cgiHistData
• The system is quite hacker-friendly; under your own responsibility, you can log in via SSH and tweak the web pages or whatever you need. For SSH connections, the user is "pi", the password "cloudwatcher".
• …and, as always, suggestions are most welcome.
