Mindboards

Hello community,
for a science project i need to know all the prefabricated parts of the NXT-sensors. Espeaccially these of light-, touch- and ultrasonic sensors. I thought about some kind of draft of the inside of such a sensor and i need to know the functions of its parts. It would be very nice if some people could help me because i found only very few information on different websites.
Thanks,Virenheier

You want to know how they work? For starters, I suggest you download the HDK from mindstorms.com. Here is a direct download link. Note however, the HDK is from 2006, so it's not complete (it was released well before the lego color sensor was available). There is still a ton of good info in it.

looks perfect though.
Just have to understand it now;)
If sombody has found something like this or something easier you're welcome.
