ARUPi stands for Automated Recording Unit Pi, Via Instructables user ARUPi303
It will show you how to build an Automated Audio Recording Unit for less than £150. You can use this unit to conduct research in the field of Soundscape Ecology (which is why I built this). You could use it to monitor the birds in your garden or just to make nice recordings of the dawn chorus, without having to get up really early.
