It's been a while since we talked about putting a GPS on top of a D200. [Rick] sent in his latest version. He used a nice 20 channel sirf III gps from spark-fun, a cheap D200 remote cable and a few parts to send the NMEA sentences down the wire. The biggest improvements include taking the $100 Nikon cable out of the mix and swiping power from the camera for the GPS board. All the info is there, but I had to seriously stare at his wiring instructions for a while despite the low parts count. I like to see actual circuit diagrams!
1. that's a pretty nifty little hack.
As a sort of addendum, I recently bought a BU-353 (http://www.semsons.com/glbuusbgpsre.html), which is cheaper than the sparkfun GPS receiver. I haven't had much time to play with it, but it appears to be an identical board inside for a cheaper price (comes with a USB cable too, and it's in a housing with a gasket).
I was impressed with how small the integrated sirf III + antenna unit is, so it's perfect for hacks like this.
