Anyone know a
good way to drive these, four or six
of them in an
array? I need 170 volts, 21ma all cathodes,
between 4.0 and 6.0ma
any individual cathode. I was thinking of a pic
at
each tube, sort-
of a character generator that would take an ascii
code and drive
the right segments. Some sort of escape code
would
let you send 16
bits to be interpreted literally, i.e. turn on
the
literal segments
corresponding to the bits set, for more fanciful
displays.
