Hi 
Everybody
I have dug out the Seismometers amp which I made some time ago
Which did not work out
So I went back to the diagram and the mounted on a breadboard
Then plug it into Arduino module and it’s working 
Leting the Seismometers run over night , may need a tweak or two
It looks promising
Will Take a screen image tomorrow, and post the hardware photo

Bonjour,
Super ! J’attends avec impatience.
The Arduino amplifier for the seismic instrument is working really well
pplease see attached images
You can see that the background noise is really low, the other noise is coming from Traffic from the main road
Just need now to pick up a seismic event
Will update my website with info on how to make the amp
and suggestions about the hardware … This project is very easy to put together
Update
Please note, I forgot to unplug a USB isolation module which I Use with a Oscilloscope
The isolation module blocks out a lot of signals, so the images below should be more sensitive than they are
tthanks
mick
Bonsoir,
Utilise quoi comme mat
Could you include a pic of your seismometer? I’m still undecided if I want to try building one or not…
Mick posted some pictures in this thread.
