My computer's "bad" :) . I used a different computer and I was able to view the files. I saw the Sprengnther horizontal drawing on Sean Thomas Morressey's web site years ago and  construct one from the picture  but used STM's feedback equations , a smaller mass , his feedback coil construction, and his vrdt senor. I used the finest music wire I could find for the hinges. It worked well for a while. It's acting somewhat erratic now. STM talked about degaussing the sensor. I don't know if that can be a problem with mine. I think I degaussed it when I constructed the sensor using a soldering iron but I don't know if that is a one time operation. It only records more local events now. I have to check the sensor for allignment and cleanliness. I have somewhat  dark, not good quality photos on my website www.seismicvault.com .  I suppose  you would have provided it but,
