That is a cool project you have there. I am thinking about a product that depends on detecting an RFID card at 8-10 meters but all the readers I find cost several hundreds to a few thousand dollars which is a bummer. I think the difference between Netduino and the Gadgeteer is that in the latter all the interfacing is standardized to the point that you can use as a Lego of sorts (no loose/random wiring). This is done by standardizing all the connectors between the different modules and clever API design. Here is an interview with a demo: http://channel9.msdn.com/Blogs/Clint/NET-Gadgeteer http://channel9.msdn.com/Blogs/Clint/NET-Gadgeteer And it can be bought here ($249.95 for a starter kit or you can buy the modules separately): http://www.ghielectronics.com/catalog/category/265/ http://www.ghielectronics.com/catalog/category/265/ P.S. I am not an interested party, I just thought this information would be useful.
