Hi Michael thanks for liking and following my project
InspectorBot! Also your project the
Device for Seismic Noise Analysis is awesome!

Hey Michael, I'm thinking about building this and I have a question, do you think that the wooden base causes any type of vibratory dampening in anyway?

Woods, especially hard woods, are very stiff and they conduct low frequency vibration fairly well.  I think that losses in the <15 Hz region would be very minimal. I put the base on rubber stoppers in order to damp out high (non-seismic) frequencies, but this was an intuitive choice. My outdoor device uses bolts directly from the wooden base into a concrete pad and its seismic noise is basically the same as the noise that the same device with rubber stoppers on the garage slab was recording. Good question though and I will have to formally check into this one day. I do think that a single piece of  molded plastic is the way to go eventually if this kind of design is deployed in the field. Plastic can be cheap, reproducible and rigid. Add 3 piezo elements, a center mass and then the device itself is done except for the electronics!!!

David - let me know if I can give you any advice on your version. 

Thanks for getting back with me Michael,  I've been researching some, about the science behind earthquakes and the devices that detect them, it seems that there are horizontal and vertical motion that can be picked up.

What intrigues me about UR device is, I think it has a potential in sensing undulations before the actual event (especially by looking at UR collected data,) if this theory is true, then UR line of reasoning about an array of these globally, coupled with an algorithm to differentiate "normal" tectonic movements and those that are pre-seismic events, can actually be realized.  

Thanks for liking AnanasStepper 2.0!

Thanks for the follow, I appreciate that :)

I always was interested in this field and 2 years ago I finally took the plunge :)

Thank you so much for the like :)

Good projects - I have a background in spectroscopy myself.
