I'm new here. Eagerly waiting the first JeeNodes to arrive (Thanks JC!). But, in the project I have in my mind, I'm planning to use ethernet for data transfer at some point (I've wiring ready in my house). That is, I'm planning to collect data from JeeNodes here and there to some 'hub node' and from the 'hub' to my server thru wire.
For this hub node I've two alternatives (I like it to be simple). First, I could attach an ethernet module, for example http://www.saelig.com/product/ETH042.htm, to JeeNode. This Wiznet module is running at 3.3V and interfaces with SPI. The nice thing is that the module has TCP/IP stack embedded, so it does not require huge loads of new software. Should be easy?
The second alternative would be to add HopeRF radio to an ethernet enabled board. Maybe Arduino with an ethershield extended with a HopeRF module? I also considered tuxgrapchic's device (http://shop.tuxgraphics.org/electronic/detail_avrwebserver_smd4.html) but I'm a bit worried does it have enough resources.
Now, what do you think which route should I take? As I said, this 'hub' does not have to be anyhow sophisticated, so Linux systems seem to me a little bit overkill.
Software is no problem for me, but fitting hardware pieces together might be. I did my electronics courses, but lack the practice.
