Tis strange how the brain works. I sub-consciously knew that 'U' stood for voltage, but never thought about it. I suppose being from the UK that I see Volts written as U quite often so never questioned it nor knew those over the water are not familiar. Did get me thinking though, where does the 'U' originate, closest I can find is that U is for Unterschied, which in German means "difference" (as in potential difference). Is that the correct translation? Vorsprung durch Technik indeed! But when we started using it I have no idea. One day we were all using the standard 'V' then suddenly 'U' crept in and made it's self at home! Of course we also use 'U' to mean the standard 19" or 23" rack mount unit. 1U=1-3/4". Maybe it has more uses than those?
"And it won’t stop folks from inventing either. " Thank goodness for that, the more inventions the better IMHO. Now, can anyone answer my question as to why the nixies showed a bright blue spot when I reversed the polarity, what is happening to cause it?
