Just realized that a few months ago I discovered some items I’d saved from my time in the 70’s working on precision pots for NEI (New England Instrument Co. now a division of Honeywell) and put them on display under one of my monitors.
Left to right:
- Cover from an 78FTS-233 precision pot.
- A molded flat track element (originally a Raytheon product line that NEI acquired). This particular element has a very non-linear first half of rotation and then the rest was linear, I think it went in a missile or military plane.
- Headless horseman sculpture given to me by the amatuer artist in my department. The black hooves are painted with resistofilm. (back then one of the large component makers was putting ads in EE magazines that featured sculptures made from components) Resitofilm was NEI’s patented spray coating for thin substrates, e.g. mylar & Kapton, that allowed very high precision potentiometers in virtually any size, shape, or output function.
