The following good people were helpful in providing, sometimes unknowingly, information, advice, assistance and encouragement that contributed in one way or another to the eventual development of the UltraLog dsign.
Always helpful, hosted the first UltraLog images and was invaluable in securing the purchase of my Artisto 0972 Hyperlog that sparked the whole idea.
Provides what I believe are the best quality slide rule scans on the Internet. Answers all my Hemmi questions and links me to the Japanese slide rule scene. Has kindly agreed to audit and validate the final scale design once AutoCAD work is completed.
If he doesn't have that elusive slide rule you are after now, he will soon get it for you.
Created the superb Hemmi catalogue. Always there to assist when I buy (yet another) Hemmi slide rule with a missing cursor glass.
Excellent analysis of slide rule scales and design. Lots of other fascinating topics.
Created the comprehensive slide rule museum and provides many extremely useful downloadable manuals.
Excellent slide rule reference site, again with many downloadable manuals.
Excellent slide rule reference site, includes the famous eBay search engine giving details by individual item of slide rule makes and types, purchase prices and number of bids since 1999.
Professor Joe Pasquale
Dept. of Computer Science and Engineering, University of California, San Diego. In addition to teaching computer related subjects, offers a freshmen seminar on the slide rule: its history, theory and practice. Has kindly agreed to audit and validate the final scale design once AutoCAD work is completed.
Otto van Poelje
A member of the Oughtred Society board of directors and the president of the Dutch Circle of Slide Rule Collectors. Has kindly agreed to audit and validate the final scale design once AutoCAD work is completed.
A very capable young man and a great lateral thinker to have around. One of the most talented and creative people I have ever met. Currently up to his elbows into scale design. On his web site you will find a short video of a remote controlled UltraLog doing aerobatics.
And last but not least - Nogita my darling, ever patient, supportive, encouraging and understanding.
