- 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.
