#169368 - Seismograph
Responding to: ???'s previous message
Jecksons.

First of all, I hope none of your family or friends have been affected by the Sumatra quake - 10 quakes of more than 5.9 in the area.

Secondly, making a seismograph doesn't work well with "accelerometers" - you can use the classic Lehmann type and make one in a couple of days at the most.

I made a two axis classic lehmann seismo for a friend a few years ago.
