Hi all

I am looking for specs for Lehman type sensor. As I can build a lehman
type sensor in my school with an help.

However, the specs I already aren't good, so I need better onces. If
someone has them ready. If no one has them, I need to write them up my
self.

I need the size and length in cm. I also need a suggestion for the
material needed for the mass, I was thinking about using led. But I don't
know how good idea that is. For the base of the sensor I was thinking
about using aluminum.

Please send this to my main email address, jonfr [at] jonfr.com

Thanks in advance.

Regards.
Jón Frímann.
