Of all the items I own, none embodies the Steampunk Aesthetic more than a Weston Voltmeter that I bought on ebay several years ago.
Take a look at it. Compared with later analog meters, it’s massive The voltmeter measures 10 inches in diameter and weighs about 12 pounds. The face of the device is painted black with what appear to be nickel-plated text and decoration. The earliest patent number on the central plaque is July 16, 1901, meaning that it was built no earlier than that. Its maker, the Weston Electrical Instrument Company, was well-known at the time for the high quality of its electrical measuring devices. Indeed the device seems to accurately measure electrical voltage still.
It is in the same condition as when I bought it. I’ve considered trying to clean it up a bit, but I kind of like the used appearance.
This device evokes the Steampunk Aesthetic by combining both its functionality with its completely unneeded decoration. The filigree and fancy script on its face contribute not a bit to the device’s ability to measure voltage. Yet they are as intrinsic to the device as its function.
An interesting factoid: Edward Weston, the American chemist, who started the company making, amongst other instrumentation, the Weston Cell, a very precise electrochemical cell (i.e, battery), which was recognized as the international voltage standard until 1990. He named his son Edward Faraday Weston, obviously after the great British chemist, Michael Faraday. And there’s no scientist more steampunk than Faraday!
