I have a Home Theater with a Lutron Spacer System for lighting, and a Logitech Harmony 900 for control. The problem is, not all my dimmer switches are in line-of-sight of the main blaster or mini-blasters. What I needed was an extension cable.
I had one for my older, Harmony 890, which used 3.5 mm connectors. It's mini-blasters were designed to stick on the device it was controlling. That worked for my projector, but not my lights. I had to point my 890 at each of the three gangs of lights to work. Definitely lacking the cool factor.
Once my 890 started dying (after six years of use) I got a 900. Its mini-blasters could control my lights, but only if located properly. I needed extension cables, but nobody sold them.
Fortunately Blue Jeans Cable
came to the rescue. I sent them an email, and Andrew and I worked on the specs.
Here is one of the cables I was shipped. It looks great. Note that the connectors are stereo. It's wired so that it will work with the 900's mono mini-blasters. (You can click on the photo for a larger image.)
Here is the entrance to my theater. You can see the 4-gang box on the right, clearly out of view of any seating position. I decided to put the blaster under the arm railing on the left.
Here is a wider shot. You can see how turning around to aim the remote at the stairs wasn't an ideal solution. You can also see how any blaster in the equipment rack wouldn't help me, either.
I marked the location of the bottom of the arm railing.
I drilled a ¼" hole in the wall and poked my fish stick down.
Here it is coming out under the stairs.
Pull string attached.
Arm railing back in place. Mini-blaster attached with a square of double-sided tape.
Securing the wire under the stairs. The connection is wrapped in green gaffer tape.
Pardon the fuzzy photo, but here is the main blaster in the door of the equipment rack. (Currently it's attached to the door with tape. Soon to be semi-permanently mounted with Velcro.) Note the two BlueJeans cables attached. The other one goes...
...to the other mini-blaster on the projector's downrod. It can control the PJ, as well as the the other two lighting gangs.
I'm a happy camper now, thanks for the folks at Blue Jeans Cable (forum sponsors, btw.) Give them a shout if you need something. email@example.com
