It's a "pustyak" Andrew.
The voltage for the modelling lights is 6V, and the polarity doesn't matter.
The connecting plugs are standard 2.1mm power plugs, although 2.5mm will
also fit (as will long reach versions of both, though you don't need the
long reach).
Simplest is probably to get a 4xAA battery holder from Radio Shack for each
set of modelling lights you want to power. Another alternative is to get a
large "lantern battery" with screw terminals which puts out 6V.
Or you can do as I did, get two 6V rechargeable lead batteries, which have
power enough for a Winder too. And with simple wiring added, it will allow
you also to run them in series for when you want a power supply for a motor
drive (connect - terminal on one battery to + terminal on the other, then
connect the remaining terminals to the drive. In this case polarity is
important, but is marked on the drive cable).
Use a curly lead to connect to the lights/winder, and you won't have the
unfotunate pendulum problem that Walt mentions - but you will have to carry
a mighty weight around!
The power supply for the Tpower Control 1 is an entirely different kettle of
fish - as far as I can see it is a high voltage input which does require
care, knowledge, and design capability. But I think Douglas Tourtelot has
volunteered for that ;-)

Subject: [OM] Powering macro flash modelling lights
Well recently I've begun exploring the macro possibilities with my current
OM gear and it's led me to look into using my macro flash equipment more.
However, I think it would be really helpful if I could use the modelling
lights on my flashes. This means I need either a 6V power adapter 2 or the
flash AC adapter 3 (added bonus of powering the T Power control as well).

2. Build it. How difficult would it be to build a unit? I'm guessing a
battery powered unit would probably be easier/safer to start with. It looks
like the connectors for the modelling lights are a standard connector. I
tried the various connectors for my universal AC adapter and there were 2
likely candidates (1 which fit better than the other so I'm pretty certain
which to use). I didn't proceed any further because I wasn't certain of the
voltage (although I'm guessing 6V) or the polarity to use and didn't want to
do any damage. The connector for the T Power control is different though, is
it also a standard connector?
