Yes, I like that design very much.
Do you make a vertical version of that
with a spring where the wire is ?
I would like very much to either buy a kit or the plans
from you to build my own vertical.
I lack talent in your area I need help
to make a decent sensor.
Vertical is my only interest
unless I can get a planer type
sensor in the horizontal.
Meaning a single sensor for both EW/NS.
Please email me the details.
any one of those three addresses.
I have seen a novel sensor at ASU about 1985
where two masses are N/S and E/W but
vertically at a 45 degree angle or so
making it possible to reproduce three dimensional
motion with only two sensors.
Or so it seemed to me.
I have never seen that design on the Internet.
