[Noisebridge-discuss] Ready to restart Arduino Thursdays at Noisebridge

And using the macintosh type power plug that plugs into the laptop to make covalent bonds and slight electomagnetic fields for hydrogen bonds .... Lots of cool ideas... :)

Similar to an armature used for recording movements into a computer, etc.

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.

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.

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?

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.
