Homemade EVDO/WiFi Mobile Access Point

I just received this email from the website owner who apparently did some neat stuff! Over the last few weeks I've built myself a mobile access point for my car. It's based on a Soekris net2421 embedded Linux box and uses Verizon's 1xRTT/EVDO network as its uplink, resharing it over 802.11b. Wherever my car goes, my Internet link goes! :) I finally put some webpages together on how I built it. The components are pretty cheap and anybody with basic Linux skills can build their own just as easily. I've also got it interfacing with Google Maps to do live vehicle tracking via gpsd. It also uploads pictures from an on-board webcam every five minutes or so..
