No more Wardrobe!

After some consideration, I have decided to abandon the wardrobe approach… in favour of something better. I was beginning to feel that the design was too complicated. I would have needed to mount the wardrobe to the wall, the support arm to the wardrobe, a hook to the support arm, as well as a bespoke system for rotating it out of the way. It would have reduced storage space, been unhelpful to people who do not wish to use the Omni in their bedrooms, and I would have likely needed to keep removing the contents to make space.

So, what method am I adopting now?

The wall mounted approach.

The key to this is the length of the support arm. The longest I could find was this one from RDX. It sticks out 3 feet from the wall.

When not in use it folds down like so:

Taking into account the attachment ring is set back a little. I stood where this would put me and extended my arms to see if the wall would be in the way:

No problem with leaning forward to run either:

My one concern here is that the diagonal strut might be in the way. Raising the support would increase the length of the cord, causing me to lean forward too far. It’s hard to tell without a proper assessment but there should be ways around it. Expect delivery within a week.

I’ve also uploaded a video demonstrating the new swivel I’m using:

I tried some cable management strategies and all I can say is I hope the consumer Rift will be completely wireless! It’s not impossible, but there’s a lot of DIY involved to stop the cables tangling otherwise.

See you on the forums 🙂

Mega Update!

Spent the weekend puzzling over the design and I now see this is going to be quite complicated.

 

Let’s get down to business.

I was going with the idea of putting the support assembly on top of one corner of the wardrobe, as I figured this would be the only thing in the room I could hit.

I repeated the lunge-test, and this time I dangled a thread tied to a weight down from my head to the floor, so I could measure the distance I had traveled.

It came as a shock to see it was four feet.

The problem became clear when I measured the support-arm:

It’s only about 2 1/2 feet. I’m going to bash my head into the wardrobe if I fall that way!

 

Did I consider giving up? Nope, this is the first thought that came into my head…

Hello wardrobe. I want to play a game.

Hello wardrobe. I want to play a game.

 

It became obvious that I would have to mount the support assembly in the front middle, not the corner, which meant practically removing the sides. This will reduce stability however, so I will need to add supports that keep the top from buckling, but which are out of the way of my head should I ever fall in their direction. Here is a crude drawing:

I’ll also need to make the coat rack removable, and find a convenient temporary storage solution for while I’m enjoying VR.

 

The wardrobe must be secured to the wall. A couple of brackets and expansion bolts might do.

I could leave the support arm sticking out into the room, but I’d rather rotate it neatly to one side. My lack of wood/metal working skills may be showing now, but this is the solution I’ve come up with:

schematic

 

 

The support arm has four holes in the base. I’m going to drill a couple of extra ones, and use these to secure it to a circular wooden disk. The disk will be held in place by four corners which are screwed into the wardrobe. The disk can rotate. There are four flat-topped bolts sitting in four holes that are drilled in the disk. There are also four holes in the wardrobe beneath. When the disk is rotated so that the support arm sticks out into the room, the holes line up and the bolts fall down, securing the assembly. When I’m done I use something like a latch to lift the bolts out so I can rotate the assembly to the right. There are a couple of clips attached the left-hand corners that slightly over-hang the wheel, which stops the assembly from tipping over.

 

weak carabiner

The carabiner on the strap looks a little too fragile. I’ll buy two stronger ones made for climbers and replace one on this end. I’ll shorten the cord to the desired length, sew a loop in it, and put the other one there. This will hook through a ball bearing swivel. I’m not sure which one, I’m still browsing – but I’ve seen one designed for big fish that can take 180kgs/400lbs.

The reason for a swivel is so the cord doesn’t get twisted. This could be noticeable, affect how far you can crouch, and also cause you to wobble while falling.

The swivel will go on a strong hook which is bolted onto this brace:

You might recognize it – it’s the same as on the other end! No I don’t have one, I’m going to buy another bracket. Unscrew its brace, drill a couple of holes on the end of the one I have and attach it there. The reason for doing this is simply so I don’t put too much pressure on one point of the support arm – it could fracture or bend it. The second support arm will be useful as a spare in case something goes wrong anyway.

 

So much DIY, kinda tempted to just drill into the ceiling now…
