Though not from scratch, [Avbrand] integrated a powerful set of tools into his Subaru station wagon. The system was compiled from off the shelf electronics, such as a Compaq notebook, 3G USB modem, touch screen, and an assortment of other peripherals. It is based around Windows XP, though most of the carputer-specific applications, such as backup camera integration, Google Maps – based car tracking, and automatic volume control had to be custom coded by [Avbrand] himself. Perhaps the single most impressive and useful feature of the system is synchronization with highway traffic cameras. The system streams video of segments of the highway before [Avbrand] gets to them, allowing him to make more informed navigational choices. He documents it pretty well on his website.
