It looks as if Joe Geller's lab site has finally been taken down, not surprising as it had been lingering (minus some files and images) for a least a couple of years longer than he indicated.
I thought it might be a good idea to start a thread to try to capture as much archived stuff from the site as possible. Contributions welcome.
I have a reasonable amount of stuff relating to the SVR / SVR-T and a few other bits but I never downloaded his LM399+AD587 reference (I only have the patent file), Micro-gust anemometer, Resistor Noise measurement, Magnetometer (?), Investigation into small value AC measurements on HP DMMs etc.
I've attached what I have anyway (all ZIPs, include HTML files(Firefox) and jpgs:
- SVR SVR-T Winding Down - Construction information, including temperature compensation text from Lars, and thought about winding down the lab.
- SVR Temperature Coefficient Setup - The test rig he used for characterising SVRs and SVR-Ts, including pictures.
- 10 1 Reference Divider 752 Junior - His experimental Hamon divider. Missing bottom view and XLS file.
- 6 1_2 Digit DMM Temperature Coefficients - His 61/2 digit temperature coefficient measurement page (missing all attachments).
- Misc PDFs (self explanatory)
As always, use your own cautions when opening files!
Other contributions welcome.
