I saw the WeDo sensors and hub available separately on LEGO Education website
the other day and I started wondering if I could use them for anything... No one
appears to have tried or managed to use the hub without the official software
until now and I'm not about to pay money for an application I'm not really going
to use so I started thinking if the sensors might be used separately.
Since the PF motors can quite easily be used together with the RCX if you use
the conversion cable (PF to 9V) I was wondering if the same would be true of the
sensors (proximity and tilt). I imagine the sensors must be relatively simple
things (PF protocol, low price) so I imagine the give an analogue signal.
Does anyone have any of these sensors and if so can they confirm they can be
used with the RCX? The might be a nice extension to the RCX.

I have sucessfully written a third party app that will let you
drive the WeDo from your Windows machine. Linux will be supported
fairly easily once I get the driver relinked, Mac when I get a
Mac for development :-)
Contact me offlist if interested.

The Scratch Programming laguage (http://scratch.mit.edu) now includes
blocks for controlling WeDo motors.

Thanks. From the description I get the impression you can use 1 motor and 1
sensor at a time. Can anyone confirm this?

So far as I can see from the Scratch interface, there is control of
one motor, but no sensors. (There are sensors via the ScratchBoard,
but not through the WeDo interface.)
I don't have the WeDo hardware, so have not investigated further.

I saw a "WeDo 2 Puppet" project on the Scratch website that specifically
mentions the use of the tilt senso so I suppose it must be possible to use
sensors as well.

You are correct---there is a tilt sensor and a distance sensor value
available in the sensor value block. These get shown even if the
motor blocks are not being shown, so I don't know why I missed them before.
The values are 0 if no WeDo sensors are connected to the computer.
