Hi all

My lehman type sensor is ready. I hope that it gives me up to 30 seconds
peroid. But I won't know if that is the case of not until tomorrow when I
put it online at home.

Here are two pictures of it.

If hit by a blank page, just press enter and it should load properly.

The mass is about ~1.5kg. The arm is ~70 cm and the mass is located at the
~65 cm limit of it.

I used to speaker magnets as damping magnest. The coil and the maget are
from Larry. At current setting, I should be getting 0.135V from the coil,
but that is just a guess. I will know for sure tomorrow.

It appears to be higly sensitive. The damping appears to be working nicely.

I will post more information tomorrow if needed.

Jón Frímann.
