Measureall Workbench Test Instrument

This was a Student Project of mine, it is a very basic instruments that could do most of the tasks on a test bench.

Measureall - Test & Measuring Instrument

The cabinet used, was available as a part of a Hi-Fi DIY System, The Range and Mode switches were Modular Stackable Interlocked MultiPole Switches. The rest of the Interface were wirewound pots, jacks, sockets and plugs. The front panel was Engraved Acrylic, the panel was the toughest issue we tackled.

MeasureAll Benchtop Instrument

I wanted it to look well engineered, at least on the outside. It was a total analog instrument except for the digital indication of ICL7107. Thanks to 'Intersil Hot Ideas' Applications Book.
The above belong to an instrument Measureall shown below.

Historical Electricity Teaching Instruments

In February 1975, Deborah Jean Warner, a Curator of Physical Science at the National Museum of American History, called me to ask if Kenyon had any historical physics teaching apparatus. I looked around my office.......

Historical Electricity Teaching Instruments

Electrical Measurements, Electric Motors, Electricity, Static Electricity.

Historical Electricity Teaching Instruments

Physics apparatus often goes by various names. The interrupter, the electrotome and the repeater are all the same instrument. Some apparatus has a person's name attached to it: Matteucci's apparatus or Wheatstone's bridge. Other apparatus isn't used any more: Packard's apparatus or the piezeometer.
