I think if the dimming is done by duty cycle and not by voltage control
then any poisoning would be less, but it is too difficult to say if it
goes away completely, there is too little information covering the
I have remembered that what I have done with the two tube clock in te
files section is to create an on-off timer, which you could set to
blank the tubes a 1am and bring them back on at 7am, which I think is a
better way to go. Also in that clock if the user turns the control knob
the tubes come back on for 2 minutes or so.
In an earlier clock I just let the user turn he tubes on and off as
required by turnin the control knob, which was a rotary encoder with
detents avery 15degrees. One click and they were off, another click and
they came back on.
