I was thinking that it could be used to hook up to joysticks, gamepads,
mice, etc...

OK. How 'bout a solid-state relay IAB and I'll use it to drive solenoid
valve ?

Yes ! Must have !

I figure they'd be seperate cables. (see below)

Yep, That'd be cool to : )

Not if we get people to agree on Node ID ranges for various devices or store
the ID's in flash.

agreed !

I figure we can supply all four with 2 existing cables/connectors per
module.
1 for power
1 for I2C. daisy chain them so you get the bus like you mentioned.

OK. I'm not in a hurry : )

| (...) So I imagine the need for a brainstorm brick that has a standard Lego wire connection on the top and a little I2C chip inside that would interface with existing motors and sensors. This would certainly be needed because nobody wants to butcher (...) (24 years ago, 11-Aug-02, to lugnet.robotics)
