I want to mount my HTC Vive Lighthouse in a semi-permanent way, but not drill any holes in my masonry walls. I used an Ikea ELVARLI post to make a solid mounting point for the Lighthouse.

This post is a follow-up from my Wall Mount TV post. In that post I showed how I used some Ikea floor-to-ceiling posts as a mounting point for a TV wall mount. This allowed me to wall-mount the TV without drilling any holes in my stucco walls.

I have an HTC Vive and to use the Vive you need to install or mount two components called Lighthouse to your walls or ceilings. In the past I had just set them on bookshelfs or zip-tied to something else in the room. I decided they should be permanently installed in the room that I use for VR. Since the walls in this room are stucco I did not want to drill holes. For one of the Lighthouses, it was convenient to mount it on the ceiling. For the other, discussed here, it was not convenient to mount on the ceiling so I needed another solution.

The solution is a floor-to-ceiling post from Ikea called ELVARLI. Here is a link to the ELVARLI post.

Here are some photos of the post installed in the corner of my room. I apologize for the poor lighting.

Two screws are used to attach to the ceiling. The floor mount just had a rubber gasket pressed against the floor. It has an adjustment that you use to place the post in compression once it is in the position you like.

The post comes with two nuts that slide into a channel in the upper part of the post. I realized these could be used for mounting the Lighthouse base in a very clean way. Before I saw this I assumed I would have to drill some holes. The nuts use a bolt size M6-1.00. After some experimentation I found that they should be about 3/16 inch long (yes I just mixed metric and imperial). The post does not come with the bolts - you have to buy them at the hardware store. The ones I bought were too long so I had to cut them.

Slide the nuts into the channel in the upper part of the post. Do this before you mount the post to the ceiling and tighten it down. I didn't do this at first and I had to take it down and put it back.

Once you have the post installed and the nuts sitting in the channel, then it is easy to screw down the Lighthouse mount. You can adjust it to whatever height you like in the upper part of the post.

Once the mount is installed you attach the Lighthouse and adjust the angle. I ran the power wire down the back side of the post and attached with some hidden electrical tape.
