The family and I made a spur of the moment trip to Galveston this weekend and took the stompbox with us.
I didn’t spend anytime on line but my wife was able to surf the web and IM with people for the whole trip. The connection didn’t drop once in 250 miles.
Price
It’s quite expensive for a toy. I had a hard time justifying the cost to myself but the old laptop I was using had some issues and I didn’t expect it to last long. My wife wasn’t too happy with the expense but she got over it this weekend when she was able to surf the web and IM with people while we drove 4 hours to Galveston.
If cost is a real concern, just get the evdo card and plug it into your laptop. The next option is one of the commercial 3G routers that can be up and running for under $300. It’s probably possible to do the stompbox for under $500 but it’d be tough and you’d have to scrounge a lot of parts.
Value
The stompbox is a solid and robust solution. I don’t have experience with any of the cheaper commercial routers but would expect them to be as reliable and nearly as solid. One thing the stompbox offers is endless configuration and software options. It’s 133Mhz 486 processor and 64MB of RAM make it powerful enough to run a large selection of applications. If you’ve got some Linux experience, time, and a few C-notes to burn then I’d suggest giving it a try. The project has and continues to be fun.
USB
My very next step is a PCMCIA USB adapter. Fortunately these things aren’t too expensive if you’re patient on ebay. I may even build a small 5V power supply that taps off the 12V in to allow more devices. From this point on any other peripherals will have to be USB or RS-232. The obvious advantage of USB is that the device can be powered by the port.
GPS
Now what good is a mobile router if it doesn’t know where itself is? The original stompbox image supports gpsd and I plan to get one of the small “gps mice” that are on ebay for $50-60. Once we know where we are and export that information with gpsd we can use a wide range of scripts or apps to access it. A laptop running linux in the car can get gps data over the wifi, we can send the data off to a web server for real-time vehicle tracking and we can also log to a local disk for some war driving logs.
