Also while at the LEGO Engineering Conference, they spoke about the upcoming NXT Temperature Sensor. They had a basic CAD picture of it, and they are sending me a more detailed picture in a few weeks. It has a range of -20 to +110 degrees Celsius, and quite a long sensing area. Those of you familiar with the original RCX temperature probe will remember that the sensing head, the part you were 'allowed' to immerse in liquids was only a few millimeters long. This new sensor has a probe that looks around 80mm long, perfect measuring hot cups of chocolate and icy cool drinks.
It is only being released by LEGO Education, not LEGO Retail so unfortunately it won't be available at "Shop@Home".
I'll be posting a pic of it as soon as I get a copy.
