Ken and Peter,

Thanks for the responses! I'll cross-post this to the Educator's Forum and see what comes of it. As far as the Stamp vs. SX decision, I'm leaning toward the SX with SX/B at this point, especially considering the reductions in store, especially the dev tools. And to Peter's point, it will bring the students (and myself) closer to the microprocessor. I do hope that some will move to assembly if I can stimulate them to do so with some interesting projects. C has been pretty much dropped from the college curriculum in favor of C++, Java, and VB. A pity; it's also much closer to the machine.

The reason for considering ZigBee is that we hope to outfit some crab boats to do some data collection as they travel the sounds around here. Hopefully, we can develop a system where the boats will join the sensors in an ad hoc network as they pass. Once established, the sensors will dump their data to the boats, and the boats will dump their collected data at the dock. Will eventually hope to gather salinity, oxygen levels, pH, and water temps. Glad I don't have to buy the sensors! Again, this is down the road, we will start with temp and timestamp to prove the concept of the RF links. I'm looking especially at the Maxstream Xbee products, off-the-shelf and only needing interfacing. Power consumption will be an issue, as well as maintenance, since few folks like to go tromping around the marshes here during warm weather, due to the cottonmouths and rattlers.

Again, my thanks,

Jim
