Hi all, I put up on the web a video of a "old" experimental vertical pivot based on the Georgia Tech classroom demonstrator of a vertical seismometer. My index "channel" on youtube is at: http://www.youtube.com/pyrolytic The title of the video is: "Vertical seismometer experimental pivot". Perhaps the video can add a certain amount of "spice" and/or knowledge insight into the normally "dry" subject of seismometers and/or design, operation etc. The video is kind of a "ad-hoc" experiment in movie making on my part...it was not previously planned out. There is other different subjects of short clips therein also. One will need a broadband internet connection to view such as it is some 38 megabytes and almost 9 minutes long.
