Weston Engineering Notes

The Weston Electrical Instrument Corporation was one of the big names of the day. Large analog voltmeters with mirrored scales ensured measurement accuracy. The Weston Standard Cell set the standard for the volt. Weston may be familiar to many for their photographic exposure meters.

The Weston Engineering Notes presented here are a fascinating glimpse into these days of electronics history. Some things are vastly out of date. Others, like the equations for a Whetstone Bridge will live on forever although few of us will try to use a slide rule to calculate the values!

The Weston Electrical Instrument Corporation has disappeared in a series of acquisitions, mergers, breakups and the revenges of business. As far as I can determine, no trace of Weston remains and there is no one to claim copyright on these documents. I was fortunate enough to pick up an unmarked file folder at a garage sale to find these Engineering Notes in near mint condition.  I'd like to think that the author would take some pleasure in knowing that engineers are still enjoying his efforts. And what efforts these notes are. Marvel at the hand-drawn artwork throughout the notes. 

The links at the bottom of this page are an 8 page pdf for each issue.  They are all fascinating reading and a view into the history of electronics and instrumentation.  If you are looking for something particular, start with the index for Volumes 1 & 2.
