It just dawned on me, and I'm not sure if this has been suggested yet but…
It would be simple to take the LEGO connectors and attach a standard socket to
it (such as RJ11) thus making an adaptor so standard plugs could be used in
making custom sensors.
NXT - LEGO plug - small wire - RJ11 socket - RJ11 plug - long wire - custom
sensor
Which makes me ask: Can anyone tell if the new sensors have the wires attached
or if they have sockets just like on the NXT? If they are not permanently
attached then we won't have to sacrifice a sensor to get the plugs. One wire
would yield two adaptors. I'm really hoping that the sensors have sockets so we
will be able to use various lengths of wires depending on the construction of
the robot.
