Neon Lighting.

Zoomup
Did you know that neon lighting was first demonstrated to the public on 11th December 1910 in Paris France. It was developed by the French chemist and physicist Georges Claude (1870-1960).

It seems a good time to demonstrate neon lighting, during the shorter days.

    Yep the good old neon.

    I used to make socket tester plugs from bog standard plugtops and two neons three resistors. R1 an N1 in series between E and L. R2 and N2 between E and N. R3 between L & N.
    N1 only lit then all is well (sort of) , N2 only lit then L & N are transposed. Both N1 & N2 lit (a little duller) then E or N missing.

    Worked reasonably well as a cheapskate quicko tester.
