Over at Make, Pičugins Arsenijs has been describing their project to create an interface for the Raspberry Pi when operating in headless mode. Hooked up to the serial line and providing a small LCD screen as a display is the first step as you have to install some software to do things like shutdown the Pi correctly, control a music player and control wifi connections. Other applications can be added to the system, which has been designed to be easily extensible. Very interesting stuff, and certainly useful if you’ve got some Pis that need re-configuring without attaching them to a full monitor. Take a look here.
