: Does anyone know if there is a device somewhere that is small, cheap, has : 1 10mbit (or 100mbit) ethernet port and a small IP stack that enable you : to set ip address and default gateway on it (dhcp perhaps?). : : I would like to put something like this at some customers to use for : pinging to see that the customer is reachable. It wouldn't be that difficult to roll a simple Altoid-tin sized board w/ an enet port (he say's before he's done it:) Seriously, there are a # of SOC in development for refridgerator web-interfaces & the like. Question is, beyond pinging an isolated device, what's most useful ? Could tack on an interface for; temp sensors, power condition monitors, ect. (Bear in mind, increasing the feature-set, esp.code requiring more memory, adds dev time, cost,...) Further, how to best power; wall wart, batt, combination of the two ? Sounds like an interesting project, would it be worth the trip ? Opinions & comments please. What's important ? Tom
