A few years ago I purchased a few Raspberry Shakes and have not made very good use of them in the meantime but now would like to resurrect efforts to measure & characterize vehicle traffic occurring near the Shake. I have a few questions that perhaps you can help me with:
- Can you provide some guidelines or point to some references on how best to set up a Raspberry shake to measure near surface vibrations as I would expect from nearby vehicle traffic?
For my first attempts I mounted the Shake on a thick, flat aluminum plate which had a 10 inch spike (also aluminum) attached. The spike was inserted into the ground and (I hoped) acted as the equivalent of an antenna for mechanical vibrations to be transmitted to the unit.
There are probably better approaches but this is what I tried - do you have any comments, suggestions or references I could look into?
- The last time I used the Shakes I (with significant help from a more computer savvy colleague) we had to muck around to update the operating system (Raspian as I recall, and any other associated utilities). Should I expect to do this again? We purchased the unit over two years ago.
All and any help would be very much appreciated.
