    • Psion 5 Car Power Adaptor - May 1999, issue #137
      The Psion 5 is a marvellous hand-held computing platform that you can take almost anywhere. However, the batteries only provide about 20-30 hours use. This new project allows you to run a Psion 5 from a car lighter socket, using a switched-mode power supply to provide a clean and stable 6.0 volts.
