Ok, I'm about to start my next project and I'm looking for ideas on running
power or the best way to run power through your truss Dob.

Not being electrically minded, I know this. I want a dew heater for my
secondary and a fan to cool the primary. I also want the computer unit of
the Argo Navis to be mounted on the secondary cage. I have a few ideas
on how to achieve this. But would be interested in how others have gone
about it. I plan to use two truss poles to run power up to and through a
duel wire spider to power the dew heater. I would like to hide the Argo Navis
leads and was thinking the only likely candidate is inside one of the truss
poles, but maybe a velcro flap on the light shroud could be used to do this.
But the main concern is powering the dew heater and fan and the room a
battery likely needed to power them will take up on board. So I would
like to have an outside power source. One that can be plugged into the
base board. The tricky bit is designing some sort of swivel connector that
can be incorporated into the pivot bolt between the base board and rocker.
I have a couple of ideas involving a track and brush arrangment. But has
anyone done this before and perhaps can share an idea or two.

I would also like to add, what sort of source or power pack would be needed,
It would need to last at least a weekends worth of observing. Could you
also power the Argo Navis from the same source?
