Ari,<div> In my case, I am trying to make 'intelligent' molecular models. Remember the 3D structures/molecule models that one can make with balls and sticks? Some very cool things can be done if one can make more 'intelligence' in the model. If each ball was a mini-arduino, the balls can behave differently (i.e., simulated molecular bonds) if it knew what it was close to and how close.</div>

<div>As a total spin off question, I was thinking over the weekend of a particular problem that I have. This is a long term -- way off in the future problem. However, as we're talking about cool arduino stuff, I was wondering if anyone had any ideas.<div>
<br></div><div>I am trying to find coordinates between my arduinos (i.e., the position of each arduino compared to each other in 3D space). Imagine many arduinos "plugged together" (daisy chained in different configurations) -- I am thinking a two wire communication daisy chained between arduinos. Sometimes an arduino will have two arduinos plugged into it, sometimes three -- whatever the bus can handle. Other times, it may have one. Or it may be a 'leaf node' that has none plugged into it, but it's plugged into something else. Imagine plugging this in as you would connect nodes in graph theory. The valency of the network would be limited by the bus size and number of plugs needed to send a signal.</div>
<div><br></div><div>I'd like to have a very accurate way to represent the arduinos in 3D space relative to each other in real time. If the user picks up an arduino and moves it into a new location, it should be possible to read off the change in 3D space. (GPS not necessary -- only with respect to each other).</div>
<div><br></div><div>I know this is a very hard problem. And, I know we can triangulate one location with respect to another. However, what type of signal? A radio signal -- some type of very hacked xbee communication with radio strength? Because the system already has to have a wire between systems, can we use that to our advantage instead of having to use wireless? What's simple but effective?</div>
<div><br></div><div>Does anyone have any ideas? I won't have time to actually "do" anything with any idea as I'm suddenly *way* too busy and booked up until at least December. And, I'm already behind on a commitment I have with the ML group.... So, just looking for ideas at this stage.. to think about while I'm showering, on BART or bicycling. </div>

</div>I have a pair of xbee modules, and the usb explorer and a fio (arduino w/xbee mountings) - but I got the series 1 models, which don't do mesh networking.<br>
<br>
So far, i've just been using it for wirelessly programming - which has been fun, but not what I got them for. Once I finish up my current project (an led clock) i'll probably go back to looking at using the xbees to talk to each other.<br>
<br>
I think if I want to play with mesh though, i'll have to go with the series 2.5.<br>
