Cambridge Consultants and the Zoological Society of London (ZSL) have teamed up to count penguins in Antarctica, having previously used similar equipment to protect rhinos in Kenya and other far-off countries. Pushing the operational limits of our favourite little computer to the max by subjecting it to temperatures below -42°C, the Pi is placed inside a transparent box. The box contains other equipment which takes photos (both normal and in night vision using infrared) and then the Pi is used to transmit the photographs over an Iridium satellite network. They’ve been in place since January this year and have been steadfastly sending back photos ever since. The photos are then analysed to determine how many penguins there are. The Raspberry Pi Foundation has the full story here.
