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
