It's nowhere near the idea of a Josephson array, but if a NIST-traceable 10V +-10uV reference is good enough to satisfy your voltage-nut urges, you can buy it from www.gellerlabs.com for $35.
I also have a few standard resistors (e.g. 1.000002 ohms) that I'd be interested in calibrating, but I can't seem to come up with a practical way of doing it. Frustrating, isn't it? :-) Ed Scott Burris wrote: > Now that many of us have a nice 10Mhz reference courtesy of TAPR, > I was wondering if there was any way to use that to build a precise > voltage or resistance standard? > > I've got once of those high precision standard resistors with a sticker > on it noting the actual measured resistance.
