you need the 9v relay. Its a big black box with a yellow dial. then order from lego the The power function to 9v adapter cables. They come in a few different lengths.

Bingo!
After learning from the LBR store in Alderwood that there isn't any means currently being sold by TLG, a member of SeaLUG (who'd overheard me asking) informed me of the exact same thing Keith wrote. :-)

I found these parts on Bricklink:

Electric, Train Speed Regulator 9V

and

Electric, Train Speed Regulator 9V (12V DC) Power Adaptor 120V 60Hz

http://alpha.bricklink.com/pages/clone/catalogitem.page?P=70931&idColor=11#T=C&C=11

but I can not find any reference to "9 volt adapter cables" on either the LEGO site or BrickLink... Can someone provide a link?

Thanks, Tyler

PS. This will definitely help for my home set up and testing.

PSS. However, for large displays, how can we power a bunch of Power Functions motors and potentially some NXT stuff? Do we need this set-up for each item in the display?

Hey Tyler,

Sounds like you are trying to do the exact same thing I've been working through.

If you do end up bricklinking the train controller let me know and maybe we can both get one and split the shipping?

I'm pretty sure this is the cable Keith is talking about:

http://shop.lego.com/en-CA/LEGO-Power-F ... -Wire-8886

AFAIK that can be connected to the train controller allowing you to use power functions motors without needing batteries.

I think the other option is, if you have an old transformer you can attach it directly to the battery terminals.

NXT is a whole other can of worms.

This is correct. Without totally re-wiring a system and getting to know a lot more about electronics and soldering, the train speed regulator system and the adapter wire is a good way to go. You can place the current PF controllers in series into the system after that to give you some control over specific motors.
I own a bit of Lego. A little obsessive by some peoples standards.

While I am sure that the options for powering up Allan is an interesting discussion on its own, but it wasn't what I was going for...

Paul: AC (in this context) stands for ALTERNATING CURRENT... I hope this helps guide your way though the remainder of this conversation topic....


... and now back to the main topic of this discussion...

Another option for those who don't mind ALTERING their battery box, and have a minimal amount of electrical skill, and access to a few simple tools:

OK as an electrician I'm scared to look at what the other end of that looks like, it's not grounded? :P :shock:
(I'm kidding it doesn't need to be unless its metal)
