It was a time long ago. Before transistors and LEDs. The Eniac computer was under development with nearly 20,000 vacuum tubes. A computer on every desk wasn't even a concept yet. Tools at the engineer's disposal include slide rules and math books filled with log tables. The view above shows the important tools of the day.
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 Some things are vastly out of date.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'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.
